1. Pohl, Samantha Kaye. Effects of the Anticoccidial Drug Amprolium on Broiler Breeder Performance and Enteric Health Following Coccidiosis Vaccination.

Degree: 2012, Texas A&M University

Two experiments were performed to evaluate effects of amprolium administration at specific times and concentrations in replacement broiler breeders of three genetic lines vaccinated against coccidiosis. Effects on performance parameters including body weight and flock uniformity, and post-vaccination oocyst cycling patterns were evaluated in addition to development of immunity following clinical Eimeria challenge according to gross and microscopic lesion scoring, post-challenge body weight gain (BWG), and total oocyst output. Experiment one was conducted on fresh pine shavings while experiment two was conducted on used litter remaining in treatment pens from the first trial. No significant differences were seen among treatment groups with regard to body weight in either trial. Increased magnitude of oocyst shedding was observed in trial one, Line A with the group receiving amprolium on day 10. Trends in the data indicated increased uniformity in Line A related to amprolium administration following day 21. The group in Line A receiving amprolium at day 10 showed a significantly lower degree of total oocyst output following challenge than the other medicated groups. The group receiving amprolium on day 10 in Line B showed significant reduction in post-vaccination oocyst shedding following treatment in both trials while all shedding was delayed in trial two when compared to the first trial. Effects on uniformity in Line B pullets varied between trials with trends indicating it being advantageous when used litter was a factor. Higher post-challenge BWG was observed in Line B pullets administered the low concentration at day 16 than the controls. Reductions in gross lesion development were seen in Line B pullets in both trials. Line C pullets receiving the highest concentration of amprolium at day 16 showed significantly less uniformity in trial one while the controls appeared to perform better than all medicated groups in trial two. All medicated groups in Line C exhibited delayed and increased magnitudes of oocyst shedding in trial two. These data indicate that the effects of amprolium on performance and immunity development are variable according to genetic strain and indicated that administration may be influenced by litter condition.

2. Fabiano José Ferreira de Sant Ana. POLIOENCEFALOMALACIA EM RUMINANTES.

Degree: 2010, Universidade Federal de Santa Maria

Na primeira parte dessa tese, foram estudados a epidemiologia, os sinais clínicos e a distribuição das lesões no encéfalo de 31 casos de polioencefalomalacia (PEM) em bovinos do Estado do Rio Grande do Sul (13 casos) e da Região Centro-Oeste do Brasil (18 casos). As taxas de morbidade (0.04%-6.66 %), mortalidade (0.04%-6.66 %) e letalidade (50%-100%) foram semelhantes em ambas as regiões estudadas. Os casos ocorreram principalmente em bovinos criados de forma extensiva em pastagem. Na Região Sul a doença afetou principalmente bovinos jovens, enquanto que principalmente bovinos mais velhos foram afetados no Centro-Oeste. Os sinais clínicos mais freqüentemente observados incluíram cegueira, incoordenação, andar em círculos, opistótono, decúbito e movimentos de pedalagem. A evolução do quadro clínico variou de 12 horas a 8 dias. Em 11 encéfalos não foram observadas alterações macroscópicas; as principais alterações macroscópicas nos outros casos incluíam congestão com tumefação e achatamento das circunvoluções, amolecimento e amarelamento do córtex telencefálico, focos de hemorragia no tronco encefálico, cerebelo e telencéfalo e herniação cerebelar. As principais alterações histológicas ocorreram no córtex dos lobos telencefálicos occipital, parietal e frontal; no entanto, lesões menos acentuadas e menos frequentemente observadas ocorreram no hipocampo, núcleos da base, tálamo, mesencéfalo e cerebelo. O tipo de lesão microscópica cortical era consistente em todos os casos e incluía necrose neuronal laminar segmentar, espongiose, tumefação do núcleo das células endoteliais, astrócitos Alzheimer do tipo II e infiltração por células gitter. Em 20% dos casos havia um leve infiltrado celular linfo-histiocitário e em 13% dos casos havia leve infiltrado de neutrófilos e eosinófilos. Adicionalmente, lesões necro-hemorrágicas leves ou moderadas foram observadas em 49% dos casos nos núcleos da base, em 39% dos casos no tronco encefálico e em 26% dos casos no tálamo. Na substância cinzenta dos telencéfalos frontal, parietal e occipital, as camadas granular externa e interna foram as mais afetadas tanto por neurônios necróticos quanto por edema. Tanto os giros quanto os sulcos foram afetados igualmente. Na segunda parte da tese, foi estabelecido um modelo experimental para o estudo da etiologia, patologia e patogênese da polioencefalomalacia em ruminantes. A condição foi induzida em cinco ovinos pela administração oral de amprólio nas doses diárias de 500 e 1.000 mg/Kg de peso vivo, respectivamente por 28-59 dias e 13-39 dias. O curso clínico foi de 3-7 dias. Os sinais clínicos incluíam depressão, incoordenação, midríase, bruxismo, cegueira e decúbito com opistótono e movimentos de pedalagem. Salivação excessiva e posição de cavalete foi observada em um ovino e mioclonias em um outro. Os principais achados de necropsia restringiam-se ao sistema nervoso central e incluíam tumefação do encéfalo com achatamento dos giros telencefálicos e hemorragias nos lobos parietal e occipital do telencéfalo. Histologicamente, havia necrose… Advisors/Committee Members: David Driemeier, Ricardo Antonio Amaral de Lemos, Glaucia Denise Kommers, Claudio Severo Lombardo de Barros, Ana Lucia Pereira Schild.

3. Golomazou, Eleni. Μελέτη της εποχικότητας και του ποσοστού μόλυνσης των μυξοσποριδίων σε άγριους πληθυσμούς θαλάσσιων ψαριών και μελέτη ορισμένων ανοσολογικών παραγόντων της έμφυτης ανοσίας σε πειραματικές μολύνσεις χιόνας (diplodus puntazzo c.) με το παράσιτο enteromyxum leei Diamant, Lom & Dykova 1994.

Degree: 2007, University of Thessaly (UTH); Πανεπιστήμιο Θεσσαλίας

The present thesis concerns the study of myxosporea infections in Mediterranean maricultured species, with emphasis in the myxosporea infection caused by Enteromyxum leei Diamant, Lom & Dyková 1994. The objectives of the present thesis were: - The estimation of the myxosporea infections in greek aquaculture, in Sparidae family cultured fish, which are the largest part of Greek mariculture and the role of wild fish as myxosporea reservoirs in cultured fish, as well. - The study of E. leei transmission and immune response in receptor fish subjected to experimental infection of E. leei. - The estimation of the efficacy and the toxicity of orally administrated anti-coccidial drugs, commonly used for other cultured animals, for innovative treatments of E. leei in infection in sharpsnout seabream (Diplodus puntazzo Cetti 1777). The thesis is divided in four Chapters, Introduction, Material & Methods, Results and Discussion. In the Introduction, the relevant literature is reviewed. The Chapter is subdivided into four Parts. In Part A, the World, European and Greek aquaculture situation is described. In Part B, the pathological problems that are observed in aquaculture are described. In Part C, the literature of the most important myxosporea infections observed in Mediterranean aquaculture is reviewed. In Part D, the literature associated with the immune response of fish against infections and in particular protozoan parasites is reviewed. In Material and Methods, the protocol used in each experiment and the laboratory techniques used for the detection of parasites and for definition of immunological parameters are described. The statistical packages used for the statistical analysis of the results are also described. In the Results, in subchapter 3.1, an estimation of the seasonality and prevalence caused by myxosporea infections in wild and cultured fish species in Greece is described. E. leei has been observed in both cultured and wild fish neighboring cages of cultured fish. Sharpsnout seabream proved to be the main host of this parasite where the highest prevalence and mortality rate were observed, while white seabream (Diplodus sargus Cetti 1777) proved to be also a significant host. E. leei was also observed in wild gilthead seabream (Sparus aurata Linnaeus 1758) and mullets (Mugil cephalus Linnaeus 1758) neighboring cultured fish. The main target organ of all infected fish was the intestine. In cases where high prevalence was observed in cultured sharpsnout seabream and white seabream, the gallbladder and the gills were also target organs. This is the first time that renal tissue is found as a target organ of this parasite; E. leei mature spores being observed in the kidney of heavily infected cultured sharpsnout seabream. Polysporoplasma sparis Sitjà-Bobadilla & Álvarez-Pellitero 1995, has been observed in both cultured and wild fish neighboring cages of cultured fish. Gilthhead seabream proved to be the main host of this parasite, but it was also observed in cultured sharpsnout seabream. This is the first time that…
