▼ Previous research has documented shifts in microbial hindgut populations resulting from dietary starch inclusion, and recent evidence indicates only 30% of equine cecal contents has been cultured successfully. Next generation sequencing (NGS) techniques allows detection of new species previously undetected. Therefore, the objective of this study was to determine community profiles equine cecal microbiota in response to abrupt dietary starch inclusion. Seven cecally cannulated Quarter horse geldings (497 to 580 kg) were utilized in a crossover design with two 28 d periods and a 28 d washout between each. Horses were randomly assigned to dietary treatments consisting of commercial concentrate offered individually at either 0.6% (LS) or 1.2% BW (HS; as fed) daily divided into 2 meals at 12 h intervals. Prior to start of each period horses were allowed ad libitum access to coastal bermudagrass (Cynodon dactylon) hay and concentrate was fed on d 1 with no adaptation. Samples of cecal fluid were collected on d 1 prior to 0 h and 3, 6, 9, and 12 h post morning meal and on d 1, 2, 3, and 7 at 6 h post morning meal. Cecal pH was determined immediately and a samples of cecal fluid were stored. Genomic DNA was extracted and the V4-V6 segment of 16s rRNA gene was PCR amplified using universal Eubacterial primers 530Fand 1100R and sequenced on the Roche 454 FLX platform. The reads were denoised, chimera checked, and Operational Taxonomic Units (OTUs) were identified using the reference Ribosomal Database Project 16S rRNA dataset. Data were analyzed using PROC MIXED procedure of SAS. Bacterial phyla were largely unaffected by dietary treatment for the first 12 h after the initial concentrate meal except for Verrucomicrobia which was greater in LS horses (P ≤ 0.04). Regardless of treatment, Bacteriodetes increased (P ≤ 0.02) over the first 12 h following initial addition of dietary starch. Adaptation to dietary treatments over 7 d resulted in decreased numbers of Tenericutes (P ≤ 0.07) in HS horses compared to LS. Cecal environment and microbial populations were altered after abrupt and long term exposure to dietary starch.

▼ Eight cecally cannulated Quarter Horse geldings were utilized in a crossover design with two 28 d periods with a 21 d washout period between. Horses were adapted to dietary treatments from d 1 to 19, dry matter intake was determined from d 20 to 24, and cecal fluid was collected on d 28. Horses were paired by age and body weight (BW) and randomly assigned to treatment. Treatments consisted of housing horses individually in stalls or group housed in a dry lot pen. Regardless of treatment, all horses were individually fed a pelleted concentrate at 1% BW (as fed) offered twice daily 12 h apart. All horses had ad libitum access to coastal bermudagrass hay. Hay was offered to stalled horses initially at 2% BW (as fed) then adjusted based on 120% of a previous 3 d average of voluntary intake. A dual marker system was utilized for estimation of voluntary intake in all horses using titanium dioxide (TiO2) as the external marker and acid detergent insoluble ash (ADIA) as the internal marker. Cecal samples were collected 4-h after the morning meal and immediately analyzed for pH. Samples were transported to the USDA/ARS laboratory to enumerate total anaerobic bacteria and lactic acid bacteria, and to determine methane and ammonia activity. Cecal pH was influenced by housing (P = 0.02) with group housed horses having lower cecal pH values when compared to stalled horses (6.52 +/- 0.04 and 6.69 +/- 0.04, respectively). The cecal pH values of this study are similar to other reported values when feeding similar diets (5). Populations of cecal total anaerobic bacteria and lactobacillus were not influenced by housing (P >= 0.21). Treatments did not affect the production of acetate, propionate, or butyrate (P >= 0.15). Additionally, methane and ammonia production were not affected by treatments (P >= 0.17). Forage intake was greater for group housed horses (P = 0.04) than stalled (8.47 +/- 0.89 kg DM/d and 5.17 +/- 0.89 kg DM/d, respectively). In conclusion, confinement housing did not greatly influence the cecal environment of a horse when similar diets were offered. Advisors/Committee Members: Coverdale, Josie A.

▼ Escherichia coli O157:H7 serotype is worldwide zoonotic pathogens responsible for the majority of severe cases of human enterohemorrhagic Escherichia coli (EHEC) disease. The aim of this study was to investigate the prevalence and antimicrobial resistance pattern of E. coli O157:H7 in goat slaughtered at Dire Dawa municipal abattoir, Ethiopia. A total of 235 samples were collected from cecal contents, carcass and environment sample (slaughter house worker’s hand, knife and carcass wash water) as 93, 93 and 49, respectively through the months of January and April. E. coli O157:H7 was identified by the method slightly modified to ISO 16654:2001.The samples were initially enriched in modified trypticase broth containing novobiocin supplement, followed by plating onto sorbitol MacConkey agar. Consequently, the suspected non-sorbitol fermenting (NSF) colonies were confirmed as E. coli biochemically using indole test and selected for serotyping. Out of 235 samples collected, the overall prevalence of 2.55% (comprising of 2.15%, 3.22% and 2.04 of cecal contents, carcass swab and environmental samples respectively) had positive results for Dryspot E. coli O157 latex test kit (Oxoid, DR120M). Eighteen different antibiogram belonging to 10 pharmacological groups including ampicillin, amoxycillin-clavulanic acid, cefotaxime, ceftriaxone, cefoxitin,cefuroxime Sodium, chloramphenicol, ciprofloxacin, erythromycin, gentamicin, kanamycin, nalidixic acid, nitrofurantoin, norafloxacin, streptomycin, sulfamethoxazole-trimethoprim, sulfonamides cpds, tetracycline were used for antimicrobial susceptibility test. Resistance to erythromycin was noted in all of the isolates (100%, n=6/6). Most of E. coli O157:H7 isolates also showed high resistance to ampicillin (83.3%, n=5/6) and moderate resistance to nitrofurantoin (50%, n=3/6). All the isolates were resistant to at least two of the antibiotics tested. No isolated E. coli O157:H7 strain resistance noted to cefotaxime, ceftriaxone, cefuroxime sodium, chloramphenicol, ciprofloxacin, gentamicin nalidixic acid and norfloxacin. This study concludes that the occurrence of E. coli O157:H7 and E. coli O157:H7 multiple antibiotic resistant profiles in goat slaughtered at Dire Dawa municipal abattoir and this may show a risk for public health and food safety. Regulatory control of antibiotics usage in livestock production, meat hygiene and pharmaco-epidemiological surveillance in food animals is hereby recommended to ensure consumer safety. Advisors/Committee Members: Dr. Aklilu Feleke (advisor).

▼ Salmonellosis is one of the most important bacterial food borne illnesses worldwide. Among the many Salmonella serotypes, Typhimurium is the most commonly implicated serotype in human disease in the United States. A major source of infection for humans is consumption of chicken or egg products that have been contaminated with S. Typhimurium. The breadth of knowledge regarding colonization and persistence factors in the chicken is small when compared to our knowledge of factors that are important for these processes in other species used in Salmonella research, such as cattle and mice. Defining the factors important for these processes in the chick is the first step in decreasing the transmission of Salmonella between animal and human hosts. In this work, we developed a chicken model to identify and study intestinal colonization and persistence factors of Salmonella enterica serovar Typhimurium. We studied the degree of enteric and systemic colonization of wild type S. Typhimurium ATCC14028, one of the most widely studied Typhimurium isolates, in White Leghorn chicks and in Salmonella-resistant CBA/J mice during infection. Furthermore, we determined the distribution of wild type S. Typhimurium and a SPI-1 mutant (invA) during competitive infection in the cecum of 1-week-old chicks and 8-week-old mice. Cell associated, intracellular and luminal distributions of these strains in the cecum were analyzed as total counts in each compartment and also as a competitive index. Localization of S. Typhimurium ATCC14028 and the role of SPI-1 in colonization are well studied in murine models of infection, but comparative infection in chicks with the same strain has not been undertaken previously. We show that the cecal contents are the major site for recovery of S. Typhimurium in the cecum of 1-week-old chicks and Salmonella-resistant mice. We also show that while SPI-1 is important for successful infection in the murine model, it is important only for cell association in the cecum of 1-week-old chicks. Finally, we found that in chicks infected at 1 week of age, bacterial counts in the feces do not reflect those seen in the cecum as they do in mice. Advisors/Committee Members: Adams, L. Garry (advisor), Andrews-Polymenis, Helene L. (advisor), Ihrig, Melanie (committee member).

Purpose: Indiana Pouch ileocecal reservoir is currently an accepted and widely used form of continent urinary diversion. We report long term results and complications including metabolic and nutritional consequences as long as the results of the urodynamic evaluation of the reservoir and the continent mechanism, in order to establish the efficacy of this method. Material - Method: We reviewed 33 patients. 32 with bladder cancer and one with fibrosed bladder due to tuberculosis, to mean 2,5 (2 - 9) years, after radical cystoprostatectomy and continent urinary diversion according to the Indiana Pouch procedure, between January 1989 and September 1998. All patients underwent complete laboratory and radiological examination.Laboratory studies included blood count with Ht and MCV (mean corpuscular volume). Serum was analyzed for electrolytes, Urea, Creatinine, Calcium, vitamin B12, vitamin D and folic acid. Arterial blood gases were measured in order to estimate the acid - base homeostasis. Radiological examinations included pouch - ο -gram, I.V.P., C.T. and bone scanning. Urodynamic evaluation performed in 18 patients including measurements of the capacity, and the pressures inside the pouch and the tapered distal ileal segment. Results: Blood measurements were found within the normal values. Arterial blood gases were found also normal. There was no nutritional disturbance confirmed. As long as the upper urinary tract morphology concern, four patients developed middle-severe ureterohydronephrosis. In the urodynamic studies the mean maximum functional volume was found 540 ml, the mean maximum pressure inside the pouch was found 22,95 cmH20, and the mean tapered ileal resistance was found 20,89 cmH20. 4 patients were found incontinent. 2 of them had increased contractility of the pouch. The mean rate of intermitted catheteriazation was 6 / 24h (3 -10). The long term complications were lymphocele, pouch calculi, parasternal hernia, stomal stenosis and recurrent pyelonephritis.Conclusion: Indiana pouch ileoceacal reservoir provides all the necessary advantages that an urinary diversion requires. Although the use of intestinal segments in the urinary tract may cause metabolic disorders, and the resection of colonic and ileal segments may result malabsorption and a decrease in intestinal uptake of different substances, Indiana pouch ileoceacal reservoir does not causes metabolic or nutritional disorders. It offers large capacity, decreased pressures, continence and protection of the upper urinary tract. Therefore it provides an acceptable performance status for the majority of the patients.

A busca por novos fármacos inspirados em substâncias de origem natural é uma estratégia conhecida e há tempos utilizada. As lactonas sesquiterpênicas (LST) são um grupo de substâncias amplo e diverso com várias atividades farmacológicas descritas, e cuja característica estrutural determinante é a de um esqueleto principal contendo 15 átomos de carbono e um anel lactônico. O mecanismo de ação das LST está intrinsicamente relacionado com reações de adição do tipo Michael frente a biomoléculas, provocando alquilações. Há na literatura estudos aprofundados sobre a química medicinal das LST, entretanto pouco há sobre o metabolismo desse grupo de substâncias em ambientes fisiológicos. Neste sentido, este trabalho é focado no estudo do metabolismo e também das vias de fragmentação por eletrospray da budleína A, que possui estrutura química do tipo furanoeliangolido, e pertence à classe dos germacranolidos. Foram realizados ensaios in vitro utilizando-se os modelos de oxidação biomimética com metaloporfirina, microssomas hepáticos e metabolismo pela microbiota intestinal de ceco de porco (pig cecum model), sendo nos dois últimos testado também o correlato 4,5-dihidro-2\',3\'-epoxi-15-desoxigoyazensolido. O estudo de fragmentação também abordou a comparação entre budleína A e a centraterina - um estereoisômero que se diferencia apenas pela orientação da cadeia lateral ligada ao C-8 - em espectrômetros distintos e com suporte de métodos computacionais para cálculos de energia (Gaussian 03 em base B3LYP/6-31G(d)). Nos estudos de fragmentação observou-se a diferença de intensidade dos sinais para íons fragmento comuns às duas LST (m/z 275, 257 e 83), além da presença do íon fragmento de m/z 293 apenas para a budleína A, permitindo a diferenciação destes isômeros por meio de espectrometria de massas com ionização por eletrospray, sem a necessidade de ressonância de magnética nuclear. Os produtos de oxidação detectados na reação com metaloporfirinas acusaram a epoxidação na cadeia lateral envolvendo C-2é C-3ćom a formação de diastereoisômeros. No ensaio com microssomas não foram detectados produtos para a budleína A, enquanto que para a substância correlata observou-se a abertura do epóxido na cadeia lateral e adição de uma hidroxila, formando um diol vicinal. No modelo de ceco de porco observaram-se a formação de adutos de LST com o aminoácido cisteína, os quais foram posteriormente degradados pela ação da microbiota intenstinal, dando origem a diversos metabólitos compostos pela LST e partes de cisteína. Sendo assim, este trabalho lança bases para a maior compreensão do metabolismo de LST do tipo furanoeliangolido em modelos distintos e também contribui para os estudos de espectrometria de massas para este tipo de substância, além de descrever uma ferramenta analítica útil na diferenciação de dois estereoisômeros.

The search for new drugs inspired on compounds from natural products is a wellknown strategy with several successful cases. Sesquiterpene lactones (STL) are a wide and diversified group of compounds which…

A capivara, um roedor herbívoro de estômago simples, vem sendo apontada no mercado de carnes por ter um excelente desempenho zootécnico. Sua carne é apreciada e sua carcaça valiosa, apresenta elevado potencial reprodutivo e manifesta eficiente aproveitamento dos alimentos. Este, provavelmente seja conseqüência da realização da cecotrofia, que faz do ceco, importante órgão na fisiologia digestiva deste animal. Neste trabalho, utilizaram-se dez capivaras adultas, provenientes do criatório da Fazenda Cachoeirinha localizada no município de Viçosa-MG, das quais obtiveram-se dados a respeito da anatomia, histologia e quantificação de células endócrinas e gânglios nervosos do ceco. Foram coletados fragmentos do ápice, corpo, base, da tênia cranial e da região de transição íleo-cecal. Macroscopicamente, o ceco é volumoso, saculado, apresentando capacidade volumétrica média de 3,6 1,7 l e comprimento médio de 70 16,2 cm correspondente a 25% do intestino grosso com média de 280 60 cm. Histologicamente, o ceco apresentou glândulas simples tubulosas de tamanho médio de 0,2 0,02 mm, com epitélio simples cilíndrico secretor de muco, uma única submucosa altamente vascularizada contendo gânglios nervosos de fácil visualização, uma túnica muscular desenvolvida e com numerosos gânglios mioentéricos. Quantitativamente o ceco apresentou um número médio de 2,0 1,0 gânglios submucosos/mm2, 6,7 3,0 gânglios mioentéricos/mm2, 173,1 60,8 células argirófilas/mm2, 207,8 68,3 células argentafins/mm2 e 55,7 27,4 células imunorreativas à serotonina/mm2.

The capybara, an herbivorous rodent of simple stomach, has been pointed out in the market of meats for having an excellent zootechnical performance. It has appreciated meat, valuable carcass, high reproductive potential and presents efficient food usage. The last item must be a consequence of the cecotrophy, which makes the cecum, an important organ in the digestive physiology of such animal. To carry out this study, ten adult capybaras from Cachoeirinhas` Farm in Viçosa-MG, were used. From them it was obtained data regarding the anatomy, histology and quantification of endocrine cells and nervous ganglia of the cecum. Fragments of the apex, body and base of the cranial taenia and of the area of ileocecal transition were collected. Macroscopically, the cecum is voluminous, sacciform, presenting a medium volumetrical capacity of 3,6 1,7 l, and a medium length of 70 16,2 cm completing a total of 25% of whole large intestine that measured 2,8 0,6 m on the average. The cecum histologically showed straight tubulous glands with average length of 0,2 0,02 mm, of prismatic simple mucous secretor epithelium, a highly vascularized submucosal tunic with nervous ganglia observed clearly, a developed and with numerous myenterics ganglia muscular tunic. Quantitatively, the cecum presented a medium number of 2,0 1,0 submucosals ganglia/mm2, 6,7 3,0 myenterics ganglia/mm2, 173,1 60,8 argyrophylics cells/mm2, 207,8 68,3 argentaffins cells/mm2 and 55,7 27,4 serotonin immunoreactive cells/mm2.

▼ Abruptly increasing concentrate in the ration of horses results in altered cecal dynamics which can culminate in digestive distress. Nine Quarter horses previously fitted with cecal cannulae were utilized for 3 consecutive 22-d experiments, each separated by 2 d of rest. During Exp. 1 and 2 horses were acclimated to the same ration for the initial 21 d of each period, followed by a concentrate challenge on d 22. The acclimation ration consisted of a morning meal of 0.5% BW concentrate (Omolene 200, Purina Animal Nutrition, LLC, Gray Summit, MO) fed with 1.5% BW prairie grass hay divided evenly between a morning and evening meal. On d 22 of Exp. 1, horses were fed a morning meal consisting solely of 1.0% BW concentrate while 1.25% BW concentrate was fed on d 22 of Exp. 2. Cecal samples were obtained through cecal cannulae from d 19 to 22 of each experiment every 4 h for h 24 following the morning meal each day. Cecal pH during Exp. 1 was recorded and decreased at h 12 following the concentrate meal on d 22 in comparison to cecal pH at h 12 on d 19 to 21 (P = 0.009). During Exp. 2 cecal pH increased at h 4 (P = 0.02) and decreased at h 12 and 20 (P < 0.0001) following this oncentrate challenge compared to cecal pH recorded at the same time points during the acclimation period. Experiment 3 differed from that of Exp. 2 only in the respect that during the acclimation period horses were fed, in addition to the acclimation ration, either a proprietary supplement (n = 5) or a placebo (n = 5). Cecal samples from d 19 to 22 were analyzed for pH, concentration of lactate, and concentration of VFA. Horses consuming the supplement had increased cecal pH at h 4 (P = 0.009), concurrently decreased cecal lactate (P = 0.02), increased ratio of (acetate+butyrate)/propionate at h 8 and 16 (P ≤ 0.006), and decreased VFA concentration at h 24 (P ≤ 0.05) compared to horses in the control group following the concentrate challenge.

Estudou-se o arranjo do plexo mioentérico, o número de neurônios e a área do perfil do corpo celular (µm2) dos neurônios mioentéricos, nas diferentes porções das regiões apical e basal, do ceco de ratos Wistar. Trinta ratos foram, igualmente, distribuídos em grupos de seis (G-6) e doze meses de idade (G-12S), sedentários, e um grupo com doze meses (G-12T), que foi submetido a um programa de atividade física de intensidade moderada. Foram montados preparados de membrana que receberam as técnicas histoquímica de NADH-diaforase (NADH-d) e NADPH-diaforase (NADPH-d). O arranjo do plexo mioentérico e o número de neurônios foram avaliados comparativamente entre os três grupos e entre as diferentes porções das regiões do ceco. Os neurônios das regiões apical e basal foram distribuídos em classes com intervalos de 100µm2, sendo comparadas às médias da mensuração dos pares, considerando as variáveis de idade e tratamento. Não foram observadas alterações na arquitetura do plexo mioentérico nas diferentes porções do ceco dos animais nos três grupos estudados. O número de neurônios NADH-d positivos foi maior do que o de NADPH-d em todas as porções, de ambas as regiões, de todos os grupos. O grupo G-12T apresentou maior número de neurônios NADH-d reativos do que os animais sedentários, com a mesma idade, em todas as porções do ceco, excetuando-se a porção próxima à ampola cecal. Os neurônios NADPH-d positivos não diferiram em número entre os grupos G-6 e G-12T (p-valor < 5%). A área do perfil dos neurônios NADH-d e NADPH-d reativos foi maior na região apical do que na basal em todos os grupos estudados, com exceção dos neurônios NADPH-d dos animais G-12T. Os neurônios NADH-d reativos são mais afetados pela idade do animal e pelo exercício físico do que os neurônios NADPH-d. Pela primeira vez, o número de neurônios do plexo mioentérico é reportado em porções pré-estabelecidas do ceco de ratos. Nossos resultados reiteram a importância da indicação precisa da porção estudada neste segmento intestinal.

The arrangement of the myenteric plexus, the number of neurons, and the area of the profile of neuronal body (µm2) were studied in the different portions of the apical and basal regions of the cecum of rats. Thirty rats had been, equally, distributed in groups of six (G-6) and twelve months of age (G-12S), were sedentary, and a group with twelve months (G-12T), which was submitted to a program of physical activity of moderate intensity. They had been mounted whole mount preparation and were stained with the NADH-diaforase (NADH-d) and NADPH-diaforase (NADPH-d) histochemical techniques. The arrangement of the plexus and the number of neurons had been evaluated comparatively between the three groups, and the different portions of the regions of cecum. The neurons of the regions apical and basal had been distributed in class with intervals of 100µm2, and the averages of the measurements of the pairs were compared, considering the different ages and treatments. It was not observed alterations in the architecture of the myoenteric plexus…

▼ Anxiety disorders are the most prevalent psychiatric conditions within primary care, affecting up to 29% of people across their lifetime. Generalized Anxiety disorder (GAD) is frequently comorbid with Major Depressive Disorder (MDD), resulting in greater functional impairment. Gut microbiota have been shown to modulate brain chemistry and function, possibly also playing a role in the genesis of anxiety. Bacteria are also able to produce, or interact with the host metabolism of neuroactive substances, including classical neurotransmitters and trace amines, like octopamine, which although found in trace concentrations in the mammalian brain, can affect CNS function. Specifically, trace amines can affect catecholamine release, reuptake and biosynthesis, and modulate dopamine and serotonin metabolism. We investigated whether microbiota from patients with GAD with no signs of immune activation can alter behaviour in gnotobiotic mice and whether this is accompanied by changes in metabolites within the gastrointestinal tract. Germ-free NIH Swiss mice (n=35) were colonized with microbiota from either a GAD patient (n=18) with severe anxiety, comorbid depression, and low serum and fecal octopamine, or an age and sex-matched healthy control (HC) (n=17). Three weeks post- colonization, mouse behaviour was assessed by standard psychometric tests. Emotionality z-scores were calculated to provide a robust integrated behavioural assessment. Microbiota profiles were assessed by 16S rRNA based Illumina, fecal β-defensin-3 level was measured by ELISA. After sacrifice, mouse brain BDNF and GDNF expression was assessed by immunofluorescence, and gene expression in the hippocampus, amygdala, and olfactory bulbs was assessed by Nanostring. Stool and cecum metabolites were measured in all colonized mice by multisegment injection-capillary electrophoresis-mass spectrometry (MSI-CE-MS). There were no differences in fecal β-defensin levels between mice colonized with GAD microbiota as compared to mice colonized with HC microbiota. However, GAD mice exhibited greater anxiety and depressive-like behavior compared to HC mice in the digging and tail suspensions tests. Behavioural z-scoring across all six standard psychometric tests showed a significant increase in group emotionality score means of GAD-colonized mice compared to HC-colonized mice. Mice colonized with microbiota from a GAD patient had distinct bacterial profiles from mice colonized with HC microbiota. Compared to HC mice, GAD mice had lower levels of dopamine, octopamine and acetylcholine in cecum contents. Furthermore, GAD mice had higher expression of BDNF in the amygdala, lower expression of BDNF in the hippocampus, and lower expression of GDNF in the midbrain. GAD mice also had lower expression of CCR2 in the hippocampus, higher Cnlp/CAMP in the amygdala and olfactory bulb, and higher Nfkb1 in the olfactory bulb compared to HC mice. Our results suggest that microbiota from a selected patient with GAD has the ability to induce anxiety and… Advisors/Committee Members: Bercik, Premysl, Collins, Stephen, Medical Sciences (Division of Physiology/Pharmacology).

▼ Abrupt dietary changes increase a horse’s risk for developing gastrointestinal diseases, such as colic or laminitis. Understanding the impact of various feeds and feeding practices on feeding behavior and gastrointestinal function creates a whole-animal perspective that allows for a more holistic interpretation of the effects of abrupt dietary changes on the hindgut environment. Unfortunately, few reports exist that have examined the effects of abrupt dietary changes in the horse. This study was designed to determine the effects of various abrupt dietary changes on the hindgut environment. In 4 sequential experiments, horses were exposed to an abrupt change from a baseline ration to a complete pelleted diet, an abrupt change from a baseline ration to a 100% grass hay diet, an abrupt change from a prairie hay ration to an alfalfa hay ration, and an abrupt change from a baseline ration to a large concentrate meal. These dietary challenges were chosen to mimic real-world scenarios that horse owners are likely to encounter. These experiments were arranged into a longitudinal trial in which the effects of the abrupt dietary change on cecal and fecal pH, total lactate and volatile fatty acid (VFA) concentrations, cecal lactate-utilizing bacterial populations, and fecal dry matter (DM) were compared to values obtained while horses were consuming the baseline diet. In the first experiment, decreased cecal (P ˂ 0.0001) and fecal (P ˂ 0.0001) pH values combined with increased cecal total lactate (P ˂ 0.001) and fecal VFA concentrations (P ˂ 0.0001) indicate that the abrupt change to a complete pelleted diet disrupted the stability of the hindgut environment. Because cecal pH values were below 6.0, this dietary challenge may be significant enough to elicit subclinical fermentative acidosis and, thereby, increase colic risk. The dietary change to grass hay had little impact on the hindgut environment, as pH, total lactate, and VFA concentrations remained stable (P ≥ 0.05). In general, horses may well tolerate an abrupt increase in the fibrous component of the diet and the elimination of concentrate, a dietary shift that presents a more natural diet to the horse. The abrupt change to alfalfa hay elicited alterations in cecal pH (P ˂ 0.01), total lactate (P ˂ 0.0001) and VFA concentrations (P ˂ 0.05), and lactate-utilizing bacterial populations; however, fecal parameters varied little in response to the dietary change (P ≥ 0.05), indicating that the distal hindgut may be more tolerant to abrupt changes in forage sources than the cecal environment. Here, the potentially adverse shifts in cecal parameters indicate that an abrupt change in hay type and quality alters the fermentative environment of the proximal hindgut and may increase a horse’s risk for gastrointestinal disease. Similarly, the abrupt introduction of a large concentrate meal elicited a decrease in cecal pH (P ˂ 0.005) along with increases in total lactate (P ˂ 0.001) and VFA concentrations (P ˂ 0.05) in the cecum that were consistent with previously reported… Advisors/Committee Members: Teresa L.

▼ L'encéphalopathie associée au sepsis (EAS) est définie comme un dysfonctionnement cérébral diffus induit par une réponse systémique à une infection. Chez les patients septiques, l'imagerie par résonance magnétique (IRM) a indiqué à la fois des anomalies de la substance grise (SG) et blanche (SB) associées à des troubles cognitifs graves, y compris le delirium. Pour améliorer notre compréhension des changements hémodynamiques, métaboliques et structuraux associés au sepsis, différentes séquences d'IRM ont été réalisées chez des rats ayant subi une injection ip de solution saline ou de lipopolysaccharide bactérien (LPS) 2,5h plus tôt ou une ligature et ponction caecale 24h plus tôt. Après ip LPS, l'IRM de contraste de phase a été réalisée pour étudier le flux des artères cérébrales antérieures et moyennes et le marquage des spins artériels (ASL) pour étudier la perfusion des structures cérébrales de la SB et SG. Des séquences d'imagerie par diffusion pondérée (DWI) ont été utilisées pour évaluer les changements structurels. Après la chirurgie CLP, ASL a été utilisé pour étudier les changements de la microcirculation. L'imagerie pondérée en T2, l'imagerie du tenseur de diffusion (DTI) et les statistiques spatiales basées sur les faisceaux (TBSS) ont été réalisées pour caractériser les événements structurels dans différentes structures cérébrales. Après imagerie, les animaux ont été sacrifiés et leur cerveau a été traité pour l'histologie afin de détecter l'enzyme synthétisant les prostaglandines vasoactives cyclooxygénase-2 (COX-2) et le canal hydrique astrocytaire aquaporin-4 (AQP4) dont l'expression peut être régulée à la hausse, évaluer la présence d'immunoglobulines périvasculaires (Ig) indiquant une rupture de la barrière hémato-encéphalique (BHE) et étudier la morphologie des glies puisque la microglie et l’astroglie changent de morphologie lors des conditions inflammatoires. L'IRM n'a indiqué aucun changement hémodynamique dans la substance grise après l'administration de ip LPS, alors qu'une perfusion cérébrale accrue a été montrée au niveau du corps calleux comme indiqué par l'ASL. DTI a indiqué une augmentation de la diffusion des molécules d’eau parallèlement aux fibres du corps calleux. Ces changements étaient accompagnés d'une dégradation de BHE dans la SB ainsi que la substance grise corticale et striatale adjacente tel est indiqué par la présence périvasculaire d'IgG, sans aucun changement majeur de COX-2 vasculaire ou de morphologie des glies du coprs calleux. Le dysfonctionnement du SNC induit par le sepsis a résulté en une augmentation du contraste pondéré en T2 dans le cortex, le striatum et la base du cerveau, une diminution de la perfusion sanguine dans le cortex et une augmentation de la diffusion hydrique du corps calleux et du striatum ventral. Ces changements ont été associés dans la SB à des modifications de la morphologie des glies et dans la substance grise à une expression constitutive de COX-2 et AQP4 plus faible dans le cortex cérébral.

▼ Two studies were conducted to determine the effect of litter microbiome on the ontogeny of the intestinal microbiome in broilers over a 6-week growth cycle. In the first study, composite (10 random birds/replicate) ileal mucosa and cecal luminal samples from birds reared on both fresh pine shavings and 2-year old reused pine litter were collected at days 7, 14, 21, and 42. At the same times, litter subsamples were also collected and pooled from multiple locations (brood area, along the water and feed lines, and along the walls) within the broiler house. Microbiome DNA was extracted from all samples using the RBB+C method. Bacterial community profiles were compared among samples (ileum, cecum, or litter) based on each litter type using PCR-DGGE. DGGE banding patterns were analyzed using BioNumerics V.5.1 software, and compared among individual samples with UPGMA clustering analysis using the Dice similarity coefficient. The DGGE banding patterns were also analyzed using SAS and principal component analysis (PCA). All these analyses indicated the following: 1) The two litter types appeared to have very distinct microbiomes, with the reused litter having a greater bacterial diversity than the fresh litter; 2) the litter microbiome is more influential on the ileal than the cecal microbiome; 3) all samples (ileal, cecal and litter) exhibit temporal shifts in the bacterial community structure; and, 4) the intestinal microbiome of the chickens raised on the fresh litter becomes similar to that of chickens raised on reused litter by week six. In addition to microbiome structure, further analysis of the chemical composition of the litter and bird performance in subsequent trials is needed to better understand the relationship between the condition of litter and gastrointestinal health of the broiler chicken. In the second study, a 16S rRNA gene clone library was constructed from microbiome DNA extracted from ileal mucosa and cecal lumen of young chicks (7 days of age) placed on fresh pine shavings or 2-year old reused litter, as well as the litter samples. All the recovered 16S rRNA gene sequences were identified by comparison with database sequences and analyzed using phylogenetic programs. As demonstrated in the 16S clone libraries, all samples had distinct microbiomes at day 7. The predominant genera were Lachnospiraceae Incertae Sedis (19.3%), Lactobacillus (18.1%), Enterococcus (3.4%), Faecalibacterium (3.4%), and Staphylococcus (3.2%). Although the co-occurrence of both Lactobacillus and Enterococcus species was seen between the fresh litter and the ileal clones of chicks placed on fresh pine shavings, very few co-occurrences were seen between the reused litter and ileal clones of chicks placed on reused litter. The majority of clones in the cecal library of chicks placed on reused litter were classified as belonging to Ruminococcaceae (60%), while the majority of clones in the cecal library of chicks placed on fresh pine shavings belonged to… Advisors/Committee Members: Moeller, Steven (Advisor), Zerby, Henry (Advisor).

▼ Campylobacter jejuni is a leading cause of bacterial gastroenteritis in the United States and is primarily acquired through ingestion of contaminated poultry products. C. jejuni colonizes the gastrointestinal tract of chickens asymptomatically, with the primary site of robust bacterial colonization being the mucus layer deep within the crypts of the cecum. The research presented in this thesis focuses on identifying and characterizing factors and events critical in the establishment of a C. jejuni persistent colonization in the chick cecum. We show that upon inoculation, C. jejuni invades the epithelial layer and stimulates a modest inflammatory response characterized by expression of pro-inflammatory cytokines and influx of avian polymorphonuclear cells (termed heterophils) in the cecum. We demonstrate that local invasion is dependent on C. jejuni virB11, a gene encoding a putative type IV secretion system ATPase that is not required for colonization. Inflammation evenutally subsides and C. jejuni persists in the cecal contents without evident symptoms of pathogenicity. However, C. jejuni is recovered from systemic sites (such as the spleen and liver), and antibodies are produced against C. jejuni antigens. Efforts to determine bacterial factors required for benign colonization of the chicken intestinal tract led to identification of a high affinity zinc ABC transporter in C. jejuni and characterization of ZnuA, a zinc-binding periplasmic glycoprotein that is modified by the N-glycosylation system and is essential for chick cecal colonization. Zinc is an essential trace element and many bacterial species encode high affinity zinc ABC transporters (ZnuABC) to acquire zinc in limiting environments. Evaluation of the mechanisms that limit the colonization potential of zinc uptake mutants led to the finding that zinc is limiting in the cecum due to the presence of the microbiota; without znuA, C. jejuni is unable to acquire zinc necessary for replication. A C. jejuni mutant lacking znuA colonized chicks with a limited-flora, but competed unsuccessfully in the presence of conventional cecal microbiota. We hypothesize that the microbiota use and store zinc, as well as modify host metabolic processes, thereby lowering the amount of avialbale zinc in the chick ceca.
