▼ Intestinal Schistosomiasis (SCH) and Soil Transmitted Helminithiasis (STH) are among the major public health problems in the world, especially in Sub-Saharan Africa. About 2 billion people are affected and that 300 million are ill as a result of these infections, the majority being children. In developing countries like Tanzania, poverty, poor nutrition, inadequate sanitation, lack of clean drinking-water and minimal health care makes the situation worse. The highest rates of infection are often in school aged children (5-15 years). This study was conducted to determine the prevalence and risk factors of intestinal SCH and STH and their association to nutritional status among school going children in Kilombero District of Tanzania. A cross-sectional study was conducted involving 403 school going children in Kilombero district, Tanzania. A structured questionnaire was used to collect demographic information and risk factors. Stool samples were collected and analyzed for worm eggs using Kato-Katz technique for quantification of the eggs. Anthropometric data were collected and entered into the WHO AnthroPlus program to obtain nutritional status based on Z-scores while demographic information and risk factors were entered in an excel data sheet. Data was analyzing in STATA. Chi-square or F-test was used where appropriate to measure the association of hookworm worm infections and risk factors, also association of demographic information and nutritional status. Furthermore, simple logistic regression was used to measure the strength of association. The prevalence of hookworm infection, wasting, underweight and stunting was 1.5%, 16.8%, 24.2% and 46.1% respectively. Eggs of Schistosoma mansoni, Trichuris trichiura and Ascaris lumbricoides were not detected. Children without toilets at their homes were 7.3 times more likely to be infected with hookworm than those with toilets (OR = 7.3, 95% CI = 1.4 - 37.1, p = 0.017), also participants who had not received anthelminthitic drugs (Albendazole, Mebendazole, Praziquantel or Ivermectin) in the last Mass Drug Administration were 7.6 times more likey to be infected with hookworm than those who received (OR = 7.6, 95% CI = 1.5-38.9, p = 0.015). Males had 2.43 times higher odds of stunting than girls (OR = 2.43, 95% CI = 1.63-3.65, p < 0.001), however children aged from 5-9 years had 0.32 times less odds of stunting than children 10-15 years (OR = 0.32, 95% CI = 0.19-0.51), p < 0.001). There is a substantially low prevalence of intestinal SCH and STH (predominantly hookworms), and therefore they do not have a public health impact in school going children in the study area. The observed high prevalence rates of under nutrition (stunting, underweight and wasting) may not be associated with helminths infection, signifying that it could be allied with other factors not investigated in this study such as malnutrition.

▼ Background: Soil-transmitted helminths (STHs) remain a major health threat to humans especially children throughout the world, mostly in developing nations including Ghana. The present de-worming program by the Ministry of Health is only for children of school-going age, hence occupational risk groups and non-school going children may remain as sources of infection throughout the year. Objective: To determine the prevalence of intestinal helminth infestation and associated risk factors among children attending Princess Marie children Hospital, in Accra Ghana. Method: A cross-sectional study involving 225 children was conducted between May 2015 to June 2015. Each participant was selected using consecutive sampling method that is every patient available who meet inclusion was recruited. Questionnaire and observations were used to identify socio-demographic and associated risk factors. Fresh stool samples were examined using light microscopy to identify the helminth parasites and the type of species. Data were analyzed using Stata version 12 statistical software. Results: Two species of intestinal helminths were identified with an overall prevalence of 17.33% (39 out of 225 children). The predominant intestinal parasites was Hookworm with a prevalence of 10.22% (23/225) and Ascaris lumbricoides (7.11%; 16/225). There was no double or triple infestation observed. Significant associations were observed between intestinal helminth infestation and age group beyond 47 months, place of residence, washing hands after using toilet and dirt on the fingernails of children (P<0.05). Conclusions: Significant associations were observed between intestinal helminth infestation and age group beyond 47 months, place of residence, washing hands after using toilet and dirt on the fingernails of children. Interventional programs such as deworming should be promptly commenced at Princess Marie Louise Children Hospital that should target every child attending the hospital. The control strategy that should be initiated for STH should involve periodic ant-helminthic drugs treatment of children at the risk area, particularly school-age children and non-school age children with age 0-17 years old. Keywords: Intestinal helminths, Infestation, children, Soil-transmitted helminths, Hookworm, Ascaris lumbricoides, Princess Marie children Hospital. Advisors/Committee Members: Sarfo, B (advisor).

▼ The aim of this work is to extend existing knowledge both with respect to the mode of action of anthelmintics and the biochemical and physiological mechanisms which may be disrupted by drug action. The helminth species examined include nematodes, Ascaris suum, Ascaridia galli and Trichuris ovis and cestodes, Moniezia, T. hydatigena, T. taeniæformis and Echinoccocus granulosus; the anthelmintics studied were methyridine, diethylcarbamazine, pyrantel, morantel, tetramisole, levamisole, dichlorvos, vincofos, cambendazole and mebendazole. The helminth characteristics selected for most intensive study are (a) the occurrence and properties of helminth cholinesterase and (b) the uptake of glucose. The breadth of the study was limited by the availability of fresh material and not all combinations of helminth and drug were investigated. The histochemical localisation of cholinesterase activity in whole mounts and sections of tapeworms using thiocholine esters revealed a complex network of tegumental receptors feeding a nervous system with efferents to suckers, rostellum and hook muscles. It is suggested that tapeworms have reflex arcsinvolving these structures allowing them to maintain their position in the host intestine in spite of peristaltic action. These arcs are susceptible to anticholinesterase anthelmintics. Other cholinesterase activity is associated with the scolex, cirrus, genital pore and sometimes the tegument. High cholinesterase specific activities against acetylthiocholine were measured in Echinococcus scoleces and tapeworms, but lower levels in nematodes. Differential centrifugation of homogenates was used to study their occurrence in the tissue and facilitate further characterisation. However, the enzyme was widely distributed in these species although somewhat higher in the particulate fractions. Activity was increased little, if any, by attempts to solubilise it with the detergent, Triton X-100. Cholinesterase in some fractions particularly from T. ovis, had a high temperature optimum around 60C, but never showed the phenomenon of autoinhibition by substrate at concentrations up to 10-2M. Cholinesterase in species of worm with high levels of enzyme was more sensitive to eserine inhibition than those with lower levels. In studies of glucose uptake from the medium by Ascaris and two tapeworms, it was confirmed that transport into Ascaris was strongly inhibited by certain benzimidazole anthelmintics. Transport into Ascaris, but not the cestodes, was also discovered to be sensitive to local anaesthetics such as procaine or lignocaine. Uptake into tapeworms was inhibited by the absence of sodium ions, phlorizin, iodoacetate and dinitrophenol. It was less inhibited by benzimidazoles and not at all by organophosphate anthelmintics, but was sensitive to phenolic drugs such as hexachlorophene and nitroxynil. In the dog and sheep, a number of anthelmintic drugs administered intravenously showed predominantly nicotinic effects on blood pressure and respiration supporting the cholinergic action of these drugs.…

▼ Highly prevalent HIV and helminth single infections continue to plague a significant proportion of the South African population. The geographic overlap of these infections lands to the expectation that high prevalence of co-infection with HIV and intestinal helminths exists, although this data for the South African adult population is lacking. Each of these single infections has an impact on the immune system, resulting in impaired responses due to the chronic activation. Also, both infections have an impact on the nutritional status, which may affect the potency of the immune responses, further compromising the immunity. A potent immune system requires adequate nutrition. Obesity, a form of malnutrition may mask micro- and macronutrient deficiency. Furthermore, obesity may result in low-grade inflammation, which may result is dysregulated responses. Therefore, malnutrition may start a cyclical process that may further predispose to infection, which in turn may result in malnutrition, where the cause-and-effect thread between malnutrition, infection and immune deficiency is indiscernible. Based on this, it was hypothesized that the HIV-intestinal helminth co-infection may have a deleterious effect on the nutrition and immunity of affected individuals, which may accelerate HIV progression. Thus, the aim of the study was to investigate the interaction between HIV and intestinal helminth single and co-infection with nutrition and immunity in an adult population (n = 263) in KwaZulu-Natal, a province with high prevalence of both HIV and intestinal helminths infections. The study expected to find an association between the co-infection with lower micro- and macro-nutrient levels, higher HIV viral load, increased immune activation, increased gene expression of Th2 and Treg cytokine responses and decreased Th1 cytokine responses compared to those singly infected and those uninfected with HIV and intestinal helminths. However, the study found no significant association between HIV and intestinal helminth single or co-infection with micro- and macronutrient deficiency, although a general pattern of low intake of the nutrients was noted among the investigated cohort, who had a substantial proportion being overweight and obese. Difficulty in the assessment of nutritional status in the milieu of HIV and intestinal helminth co-infection, obesity and inflammation was noted. Furthermore, HIV-intestinal helminth co-infection was associated with an antiviral cytokine response profile of highly expressed IFN-γ and TNF-α cytokine genes and reduced viral load. The co-infected individuals with the IgEhiIgG4hi intestinal helminth infection phenotype had a compromised immune profile of low CD4 counts. We recommend that antihelminthic interventions are included in the HIV management programmes, particularly in adults. Advisors/Committee Members: Mkhize-Kwitshana, Zilungile Lynette.

Dissertação de Mestrado Integrado em Medicina Veterinária

Os equinos apresentam-se, por norma, infectados por inúmeras espécies de helmintes numa complexa fauna parasitológica, muitos deles com elevada patogenicidade. Assim, recomenda-se o delineamento de programas de controlo parasitário capazes de manter baixos níveis de carga parasitária compatíveis com um estado hígido. Pretendendo avaliar a epidemiologia e as formas de controlo de helmintes intestinais aplicadas em equinos criados em regime extensivo no Ribatejo e Baixo Alentejo colheram-se, mensalmente, amostras fecais entre Dezembro de 2012 e Janeiro de 2014, de 60 equinos (20 éguas, seus poldros de mama e respectivos poldros de ano) distribuídos equitativamente por duas coudelarias: concelho de Serpa (CS) e da Azambuja (CA). As amostras foram analisadas segundo técnicas coprológicas quantitativas e qualitativas. Realizou-se ainda a técnica da fita adesiva para pesquisa de ovos/adultos de Oxyuris equi. A análise da informação supracitada permitiu propor um esquema integrado e sustentável para o controlo das parasitoses identificadas. Nas duas coudelarias, identificaram-se animais positivos aos seguintes helmintes intestinais: O. equi (CS-70%; CA-67%), estrongilídeos intestinais [EI] (CS-100%; CA-93%), Parascaris spp. (CS-59%; CA-52%), Strongyloides westeri (CS-10%; CA-4%) e Anoplocephala spp. (CS e CA-3%). O perfil de eliminação de ovos de EI nas éguas foi subtil, verificando-se apenas alguma sazonalidade nos poldros, com picos na Primavera, no Verão e no Outono. O género Cyathostomum, sensu latum foi o mais prevalente (85%) e abundante (99,7%). A eliminação de ovos de EI parece variar também em função da idade dos animais. As éguas eliminam, geralmente, valores mais baixos de ovos por grama de fezes (OPG) que os poldros, tendendo este valor a aumentar com a idade dos poldros. A imunidade tem um papel crucial na eliminação de ovos de ascarídeos, ocorrendo valores de OPG muito elevados nos poldros lactentes e nulos nas éguas. Identificou-se O. equi em poldros de 2 e 3 meses de idade sugerindo um encurtamento do período pré-patente em cerca de 50%, mas também em éguas adultas. A Doramectina revelou-se pouco eficaz no controlo destes helmintes, em especial, de O. equi, enquanto o Febendazol e a Ivermectina/Praziquantel são mais eficazes. Cerca de 94% das éguas foram desparasitadas sem justificação válida (OPG≤500).

ABSTRACT - Melo-Franco, B. (2014). Epidemiology and Control of Intestinal Helminths in Pure Bred Lusitano Mares and their Foals Raised in Extensive System in Ribatejo and Baixo Alentejo. - Horses are usually infected with several different helminths species in a complex parasitological fauna, most of them very pathogenic. Thus, the implementation of anthelminthic control programs should be considered to keep the parasite burden at minor levels, therefore compatible with an adequate animal health status. Intending to evaluate the intestinal helminths epidemiology and their ways of control in horses raised in extensive system in Ribatejo and Baixo…

▼ Little is known about substance use among extant hunting-gathering populations. I therefore conducted one of the first biocultural, and biomarker validated, studies of tobacco and cannabis among the Aka foragers of the Congo Basin. Because tobacco and cannabis contain anthelmintic compounds, and because the Aka suffer from high rates of helminthiasis, I also tested a hypothesis that recreational use of neurotoxic plants helps defend against parasites. Self- and peer-reports of tobacco and cannabis were collected from all Aka residing in the study area (n=379). Detailed questions about substance use were asked among a subset of these. Because female use was low, I restricted saliva, urine and stool sample collections to men. Saliva samples were assayed for cotinine, a nicotine metabolite; urine samples were assayed for THCA, a metabolite of THC; a subsample was genotyped for the CYP2A6 enzyme, which metabolizes nicotine. Stool samples were assayed for intestinal helminth eggs as an index of worm burden. Aka men pay more for tobacco, yet have a higher smoking prevalence (95%) than men in most other populations, whereas Aka women have a low prevalence. Aka thus have one of the largest known gender differences in smoking. Tobacco is widely shared, and might play a central role in this defining aspect of Aka culture. Significant negative correlations between cotinine and worm burden and THCA and worm burden were found. Treating helminths with a commercial anthelmintic reduced cotinine concentration two weeks later, compared to placebo controls. Significant negative rank correlations were found between year 1 cotinine concentrations and reinfection by year 2 and between year 2 THCA concentrations and reinfection. Finally, younger and older participants with slow nicotine-metabolizing alleles had lower worm burdens compared to those with extensive metabolizing alleles. Tobacco advertising cannot easily explain the high prevalence of smoking among Aka men, nor can socioeconomic disparities, proscriptions, or the addictiveness of nicotine easily explain the low prevalence among Aka women. Aka smoking might be better explained by internal, rather than external, cultural and political-economic factors. In addition, these results provide the first support for the hypothesis that substance use helps defend against parasites. Advisors/Committee Members: Hagen, Edward H (advisor).
