Abstract:

<p class="Normal1">Parasitology can be defined as the branch of biology that studies parasites and parasitism in general, covering diverse areas, such as helminthology, protozoology, ectoparasitology and entomology. Due to the large amount of content studied and the complexity of scientific names, it is generally difficult for students to fix the content taught during the course. Gamification has been gaining ground in current teaching methodologies, as it represents an alternative way of how knowledge can be passed on, as it is clear that the playful form of teaching shows a higher rate of fixation and learning. Therefore, the aim was to develop a quiz application on veterinary parasitology for Android smartphones. The game was called VetParasitoQuiz, having been made available on Google’s online store for downloads on Android devices. Then, it was tested and evaluated by the students enrolled in the discipline of Veterinary Parasitology and the discipline of Parasitic Diseases of the semesters of 2018, of the Veterinary Medicine course at the Federal Institute of Paraíba (IFPB) Sousa campus, where they evaluated the effectiveness of methods alternatives in teaching-learning, where through questionnaires and through the performance evaluation in the game, obtained positive results, showing that the gamification in higher education contributes to the fixation of subjects and that through application there is a stimulus to learning in an unconventional way , allowing greater memorization of the contents.</p>

Abstract:

Theileriosis is a severe blood-parasitic disease, an important problem in veterinary protozoology, since the damage it causes remains significant. The recently widespread practice of importing breeding stock to improve local breeds leads to the fact that in the first summer season, upon contact with infested ticks, the imported animals become very seriously ill, with a mortality rate of up to 90-100%. In this work, 738 samples of cattle were examined using the polymerase chain reaction method, which showed the presence of infection in 598 DNA samples isolated from cattle from 10 districts, 19 settlements of the Turkestan region. Whole blood samples were taken from cattle aged 3 years and older. Upon examination, the animals seemed healthy. The overall positivity rate for the entire region was 81%, highlighting the prevalence of infection among livestock. There are different levels of infection in the regions; in 6 settlements the infection rate of cattle was 100%. In addition, 7 villages showed high PCR positivity rates, ranging from 70% to 97%. While the lowest prevalence of infection showed from 18% to 69% in 6 villages, respectively.

Abstract:

This study was carried out to determine the prevalence of haemoparasites in chickens (Gallus gallusdomesticus) slaughtered at the Samaru Live Bird market of Sabon Gari Local Government Area of Kaduna State, Nigeria. A total of 100 blood samples were collected from male and female chickensat the point of slaughter. The samples were collected in heparinized sample bottles and transported to the Veterinary Protozoology Laboratory of the Faculty of Veterinary Medicine, Ahmadu Bello University, Zaria Nigeria for analysis. Out of the 100 chickens sampled, 51% were males while the remaining 49% were females. Microscopic examination of the Giemsa-stained thin blood smear revealed an overall prevalence of haemoparasites to be 81%. Forty-nine (49%) percent of these were plasmodium species, while 27%, 21% and 3% of the haemoparasites detected were Aegyptianella, Haemoproteus and Leucocytozoonspecies respectively. With respect to sex, the prevalence was higher in cocks (55%) than in hens (45%).More studies are needed to evaluate the prevalence of haemoparasites of chickens in different seasons of the year with the view of providing information that will enhance productivity in the poultry industry.

Abstract:

Objective To determine prevalence of infection with Tritrichomonas fetus in a bull population; assess influence of age, breed, and grouping; assess effects on measures of cow performance (pregnancy rate, weaning percentage, weaning weight); and estimate test sensitivity. Design Epidemiologic study. Animals 1,383 bulls and records for 28,471 cows bred by these bulls in the immediate past breeding season. Procedure Bulls in 11 cattle units on a large ranch were tested for T fetus colonization by vigorous preputial scraping and protozoologic culture until no newly infected bulls were identified. Bull infection prevalence within units was calculated and correlated to production measurements reported for each cattle unit. Results Mean prevalence of T fetus-infected bulls was 11.9% (range, 0 to 35.9%). Significant difference was detected between mean age of infected bulls (5.5 years) and noninfected bulls (3.9 years). Difference in prevalence among breeds was found, although other factors may have influenced this finding. Cow performance measurements (weaning percentage, mean weaning weight, and adjusted mean weaning weight/exposed cow) for cows exposed by breeding to bull groups with the highest prevalence of infection (35.9%) were significantly different from mean values for the entire study population. Test sensitivity for this study (73%) was less than that reported in other studies. Clinical Implications T fetus infection in a natural service beef herd has an adverse impact on several production measures. Severity of impact is related to prevalence of infection in the bull population, where prevalence is bull age and population dependent. (J Am Vet Med Assoc 1999;214:1051–1055)

Abstract:

Prophylactic administration of the immunosuppressive drug cyclosporine A protects Balb/c mice from fatal Leishmania major infections. It is believed that distinct subpopulations of CD4+ T lymphocytes and their distinctive cytokines may determine susceptibility and resistance to leishmaniasis among inbred strains of mice. CsA may enhance disease resistance in Balb/c mice by modulating these T cell subsets and/or their cytokines. We have measured lymphoid cell production of IL-2, IL-4, and TNF-a in naturally resistant C57/Bl/6, CsA-treated Balb/c, and nontreated Balb/c mice during the course of L. major infection. CsA treatment inhibited IL-2 and IL-4 production for the first week of infection. Thereafter the cytokine production of all three groups of mice did not differ greatly except in week two when the treated mice produced significantly enhanced levels of IL-4. C57B1/6 mice did produce slightly more TNF-a than either group of Balb/c mice, but as the CsAprotected and diseased Balb/c mice produced similar amounts of this cytokine, the elevation in C57B1/6 animals probably reflects a strain-related difference rather than disease resistance.

Abstract:

The aim of this thesis was to provide a picture of the trypanosomosis and drug resistance prevalence in Eastern Province of Zambia, to understand the underlying factors of drug resistance (drug use habits), to improve the diagnosis of trypanosomosis in livestock and finally, to improve the diagnosis of isometamidium resistance in T.congolense. After an introductory part where available trypanosomosis and trypanocide resistance diagnostic methods are described and discussed, the body of the thesis is divided in two main sections. In the first section are presented the results of a cross-sectional and a longitudinal epidemiological survey describing the geographical distribution of trypanosomosis cases, of resistant isolates and of cattle treated with isometamidium chloride. The results of the monitoring of unsupervised treatments of cattle with isometamidium by farmers and veterinary assistants with the Isometamidium-ELISA technique are also presented. The second section describes the development of two new diagnostic methods, the first one allowing the diagnosis of trypanosome infections with high sensitivity and specificity through semi-nested polymerase chain reaction and restriction fragment length polymorphism. This is the first report of a pan-trypanosome PCR test (a single PCR test for the diagnosis of all important pathogenic trypanosomes of cattle). The second new method that was developed allows the diagnosis of isometamidium resistant T.congolense strains by PCR-RFLP. This is the first report of a PCR based diagnostic test of trypanocide resistance in T. congolense.

Abstract:

A toxoplasmose é uma infecção comum nos animais causada pelo Toxoplasma gondii configurando-se como uma importante zoonose. O homem infecta-se, principalmente, através da ingestão de carne contaminada com cistos do protozoário. São encontradas altas taxas de prevalência de toxoplasmose nos rebanhos de ovinos do mundo todo, sendo a ingestão de alimentos e água contaminados com oocistos as mais importantes fontes de infecção da espécie. No ovino, a toxoplasmose pode ser assintomática ou causar distúrbios reprodutivos, notadamente abortos, levando a perdas econômicas consideráveis. Com o objetivo de contribuir com dados sobre a freqüência de anticorpos para o T. gondii em ovinos na região da Grande Porto Alegre-RS, foram estimadas as freqüências de anticorpos para T. gondii da classe IgG em soros de ovinos provenientes de propriedades da região citada, utilizando a técnica de Hemaglutinação Indireta (HAI) e Imunofluorescência Indireta (IFI). A freqüência estimada de anticorpos para T. gondii em uma amostragem de 250 ovinos foi de 13,6% pela técnica de HAI e 15,2% pela técnica de IFI. A amostragem foi estratificada em dois grupos experimentais de acordo com o sexo e a idade dos animais. No grupo I, composto de 127 machos, obteve-se 4,8% de positivos para HAI e 7,6% de positivos para IFI. Enquanto nas 123 fêmeas, detectou-se um percentual de 8,8% de positivas pela técnica de HAI e 7,6% reagiram para IFI. Em relação a faixa etária se encontrou: 11 positivos (4,4%) nos animais com menos de um ano e 23 (9,2%) para aqueles com mais de um ano na reação de HAI, num total de 34 (13,6%) animais; enquanto que para técnica de IFI obteve-se o resultado de 19 (7,6%) ovinos jovens e 19 (7,6%) ovinos adultos em 38 (15,2%) animais analisados. A percentagem de co-positividade entre as técnicas utilizados foi de 55,26% e a co-negatividade foi de 93,865, e a concordância total ficou em 88%, enquanto o índice de Kappa calculado foi de 0,513.
Toxoplasmosis is a serious zoonosis. It is a common infection in animals caused by a parasite called Toxoplasma gondii. Human infection occurs mainly for ingestion of meat contaminated with T. gondii cysts. A high prevalence rate of toxoplasmosis is found in sheep cattle all over the world, being the consumption of food and water contaminated with oocystes the major source of infection of the species. In ovine, toxoplasmosis can be assymptomatique or cause reproduction disorders, especially abortions, which leads to significant economic losses.With the objective of providing data about the frequency of T. gondii antibodies in sheep from the Greater Porto Alegre area, we estimated the frequency of IgG class antibodies to T. gondii in sheep sera. The techniques employed were the Indirect Hemagglutination Technique (HAI) and the Indirect Imunofluorescence Test (IFI). The estimated frequency of antibodies to T. gondii in a sample of 250 sheep sera was 13,6% (HAI), and 15,2% (IFI). The sample was stratified into two experimental groups, according to gender and age. In group one, composed by 127 males, 4,8% were HAI positive, and 7,6% were IFI positive, whereas in the group composed by 123 females, 8,8% were HAI positive, and IFI 7,6%. Concerning age group, there were 11 HAI positives (4,4%) among the animals with less than one year of age, and 23 HAI positive (9,2%) among the animals over one year, totalizing 34 animals. For the IFI technique, the results obtained showed 19 (7,6%) young sheep and 19 (7,6%) adults in 38 animals analyzed. The co-positivity between the techniques was 55,26% and the co-negativity was 93,865. Total agreement was 88% while the Kappa index calculated was 0,513.

Abstract:

A toxoplasmose é uma das enfermidades parasitárias mais difundidas entre as transmissíveis. Novos aspectos parecem justificar o reaparecimento da questão da toxoplasmose, uma vez que ela vem sendo diagnosticada em um número crescente de pacientes com imunossupressão devida a várias causas tais como doenças malignas, transplantes de órgãos e principalmente, a Síndrome da Imunodeficiência Adquirida (AIDS). Mais de 50% da população humana mundial acha-se infectada pelo Toxoplasma gondii com variações determinadas por fatores climáticos, sócio-econômicos, tipo de contato com animais, em especial o gato e costumes alimentares relacionados ao consumo de carnes. O T. gondii é um protozoário que infecta praticamente todas as espécies animais. A caprinocultura é uma atividade bastante exercida no Estado, sendo que representa 0,4% de sua atividade pecuária total. O objetivo deste trabalho foi avaliar o papel desempenhado pela espécie caprina na transmissão do T.gondii. A amostragem foi estratificada por idade e gênero. Foram analisadas 360 amostras de soros de caprinos, através da técnica de Hemaglutinaçao Indireta (HAI) e Imunofluorescência Indireta (IFI). Os resultados obtidos pela HAI estimam uma freqüência de 19 % de soro-positividade e pela IFI de 30%, o que representa índices elevados. Em relação a Hemaglutinação Indireta, na variável gênero, foi observada uma freqüência de 20,1% de soropositividade para os machos e 19,3% para as fêmeas, enquanto que na variável idade, os resultados demonstraram freqüências de 16,5% para os indivíduos jovens e 21,1% para os adultos. No que tange à Imunofluorescência Indireta, a variável gênero demonstrou uma freqüência de 14,44% de soropositivos para os machos e 15,56% para as fêmeas. Na variável idade, através desta mesma técnica, observou-se uma freqüência de soropositividade de 13,06% para indivíduos jovens e de 16,94% para indivíduos adultos. Ao compararem-se as duas técnicas os dados obtidos revelam uma associação significativa entre elas, com uma índice de co-positividade para a HAI de 78,6% e de co-negatividade de 81,7%. O índice Kappa utilizado para medir o grau de concordância entre as duas técnicas foi igual a 0,5% que evidencia um grau de concordância moderado entre as técnicas, recomendando, desta forma o uso cauteloso da HAI na espécie caprina. Os dados obtidos nos permitem concluir que os caprinos criados na região estudada podem ser fonte de transmissão de T. gondii.

Abstract:

O estudo teve por objetivo determinar a eficácia do teste de ELISA para Giardia duodenalis e identificar os genótipos do protozoário em amostras fecais de crianças e cães na cidade de Lages, Santa Catarina. Foram avaliadas 1085 amostras fecais distribuídas em quatro grupos: crianças (Grupo I) matriculadas no ensino fundamental das Escolas Municipais de Ensino Básico (EMEB); amostras fecais de crianças obtidas em um laboratório particular da cidade (Grupo II); cães em ambientes domiciliados (Grupo III) e cães provenientes do Centro de Controle de Zoonoses (Grupo IV). Todas as amostras foram processadas pelos métodos coproparasitológicos de flutuação e sedimentação para determinar a presença de cistos de G. duodenalis. As amostras processadas pelos exames coproparasitológicos foram posteriormente analisadas pelo teste de ELISA e as amostras positivas genotipadas. A prevalência de amostras positivas para o parasito foi de 7,19% (78/1085). Das 430 amostras fecais de crianças e cães analisadas pelo teste de ELISA; 19,07% (82) foram positivas para G. duodenalis. A sensibilidade do teste de ELISA foi de 66%, 100% de especificidade, valor preditivo positivo (VPP) e negativo (VPN) de 100%, valor de Kappa = 0,93 e acurácia de 93%. Em relação às populações, o teste de ELISA para o diagnóstico de Giardia em amostras fecais de crianças apresentou sensibilidade de 60% e especificidade de 100%; para cães a sensibilidade foi de 73% e especificidade também de 100%. Conclui-se que o teste de ELISA apresentou alta especificidade, porém não apresentou boa sensibilidade em relação ao exame parasitológico, que aliado ao alto custo faz com que os exames de rotina laboratoriais na área humana e animais baseados na microscopia ainda são a opção mais eficaz para o diagnóstico de G. duodenalis. Em relação à identificação genotípica de isolados de G. duodenalis, através da PCR-RFLP usando o gene gdh, o genótipo (assemblage) A foi identificado nos Grupos I e II em 59,41% (22/39) das amostras com pequena prevalência para o subgenótipo AI (54,55%); o genótipo B foi diagnosticado em 43,59% (17/39) com maior prevalência para o subgenótipo BIV (58,82%). Nos grupos caninos III e IV o genótipo com características zoonóticas (A e B) foi diagnosticado em 64,10% (25/39), sendo diagnosticado AI com 53,85% e 10,26% de BIV. Em relação aos genótipos específicos de carnívoros (C e D) a prevalência foi de 35,90% (14/39) com predominância do genótipo C (71,43%) e 28,57% para o genótipo D. O estudo identificou uma variedade de genótipos em crianças e cães, com elevada prevalência de genótipos de características zoonóticas nos cães.
The study aimed to determine the efficacy of the ELISA test for G. duodenalis and identify the genotypes of the parasite in stool samples from children and dogs in the city of Lages, Santa Catarina. We evaluated 1085 faecal samples divided into four groups: Children (Group I) enrolled in basic public education; faecal samples obtained from children in a private laboratory in the city (Group II ) domiciled dogs ( Group III) and dogs from the Center for Zoonosis Control (Group IV). All samples were processed by the methods of faecal flotation and sedimentation to determine the presence of cysts of G. duodenalis. The samples processed by fecal examinations were subsequently analyzed by ELISA and positive samples genotyped. The prevalence of samples positive for the parasite was 7.19% (78/1085). Of the 430 stool samples from children and dogs analyzed by ELISA; 19.07% (82) were positive for G. duodenalis. The test sensitivity was 66%, specificity 100%, positive predictive value (PPV) and negative (NPV) of 100%, Kappa value = 0.93 and 93% accuracy. In relation to the population, the ELISA test showed sensitivity of 60% and specificity of 100%, for children and sensitivity was 73% and specificity of 100% for dogs. We conclude that the ELISA test is highly specific but less sensitivity to parasitological examination, so the routine tests in laboratory animals and human area-based microscopy are still the most efficient option for the diagnosis of G. duodenalis. Regarding the identification of G. duodenalis genotypes, by PCR-RFLP using the gdh gene, genotype (assemblage) A was identified in Groups I and II in 59.41% (22/39) samples with low prevalence to subgenotype Al (54.55%) , genotype B was diagnosed in 43.59% (17/39) with higher prevalence in subgenotype BIV (58.82%). Canine groups III and IV genotype with zoonotic characteristics (A and B) was diagnosed in 64.10% (25/39) was diagnosed with AI 53.85% and 10.26% of BIV. In specific genotypes of carnivorous (C and D) the prevalence was 35.90% (14/39) with predominant genotype C (71.43%) and 28.57% for genotype D. The study identified a variety of genotypes in children and dogs, with a high prevalence of genotypes characteristics zoonotic in dogs.

Abstract:

finalidade a extração da pele para fabricação de casacos, mas alguns criadores utilizam sua carne como alimento. A capivara é o maior roedor do mundo, sendo o roedor silvestre mais abundante no Rio Grande do Sul. Elas são comercialmente criadas para produção de carne, couro e óleo. A giardíase é uma das doenças parasitárias mais comuns em chinchilas e uma das mais importantes também. É produzida pela Giardia lamblia, que é um pequeno parasito que comumente causa problemas intestinais, podendo causar estragos em uma criação de chinchilas. A via de transmissão é fecal-oral e como sinais clínicos observa-se diarréia, anorexia e perda de peso. A criptosporidiose é uma zoonose causada pelo protozoário do gênero Cryptosporidium.Este é um parasito intracelular obrigatório, onde a principal fonte de infecção é a matéria fecal contendo oocistos, de indivíduos enfermos ou portadores. O Cryptosporidium causa diarréia severa em chinchilas. A Eimeria é um parasito protozoário pertencente ao filo apicomplexa. A eimeriose é uma doença que ocorre em áreas de pouca sanidade e é transmitida através das fezes, contaminando alimentos e a água. As capivaras são suceptíveis a Eimeria spp. Com o objetivo de contribuir para um melhor conhecimento dos protozoários intestinais da chinchila e capivara no Estado do Rio Grande do Sul, foram utilizados os Métodos de Faust e Colaboradores, Método de Sheather- modificado por Benbrook, E. A e Método de Coloração de Ziehl- Neelsen, modificada por Angus em 250 amostras de fezes de chinchilas. Já nas 250 amostras fecais de capivaras utilizou-se apenas o Método de Sheater-modificado por Benbrook, E.A. As chinchilas foram divididas em dois grupos: grupo I, constituído por animais com idade menor ou igual a 11 meses e grupo II, constituído por animais com idade igual ou maior que 12 meses. A partir destes grupos, os animais foram classificados de acordo com o sexo em dois grupos: machos e fêmeas. As capivaras pertenciam a apenas um grupo, constituído de 250 animais. O gênero Giardia foi encontrado em 8% das amostras fecais de chinchilas. Nenhuma das amostras fecais de chinchilas apresentou oocistos de Eimeria e Cryptosporidium. O gênero Eimeria foi detectadoem 52,4% das amostras fecais de capivaras, sendo que quatro espécies foram encontradas, que foram: E. trinidadensis, E. ichiloensis, E. boliviensis e uma espécie de Eimeria que não foi identificada. Com relação ao número total de oocistos contados, a freqüência relativa das diferentes espécies de Eimeria foi a seguinte: E. trinidadensis (55,04%), E. ichiloensis (32,56%), E. boliviensis (4,77%) e Eimeria não identificada (7,63%).
Giardiasis is one of the most frequent and most important parasite infections that affect chinchillas. It is caused by Giardia lamblia, a small parasite that often causes intestinal disorders, and can negatively impact chinchilla breeding. Transmission occurs through the fecaloral route, and clinical signs include diarrhea, anorexia and weight loss. Cryptosporidiosis is an infection caused by an obligatory intracellular protozoan parasite of the genus Cryptospodidium. The main source of infection is fecal matte containing oocysts from infected or carrier individuals. Cryptosporidium causes severe diarrhea in chinchillas. Eimeria is a protozoan parasite of the pylum Apicomplexa. Eimeriosis is found in areas with poor sanitation, where oocysts are passed in the feces, and then ingested in contaminated food and water. Capybaras are susceptible to Eimeria spp. In order to investigate the intestinal protozoa that commonly infect chinchillas and capybaras in the state of Rio Grande do Sul, we used the methods developed by Faust et al., Sheater’s method modified by Benbrook, E. A., and the Ziehl-Neelsen staining method modified by Angus in 250 fecal samples of chinchillas. For the 250 fecal samples of capybaras, only Sheater’s method modified by Benbrook, E. A., was used. The chinchillas were split into two groups: group I, which consisted of animals aged 11 months or younger, and group II, which included animals aged 12 months or older. After that, the animals were classified into male and female. The capybaras belonged to a single group of 250 animals. The genus Giardia was detected in 8% of the fecal samples of chinchillas. None of these samples revealed oocysts of Eimeria and Cryptosporidium. The genus Eimeria was found in 52,4% of the fecal samples of capybaras, and the four species detected were E. trinidadensis, E. ichiloensis, E. boliviensis and an unidentified Eimeria specie. With regard to the total number of oocysts found, the relative frequency of different Eimeria species was the following: E. trinidadensis (55,04%), E. ichiloensis (32,56%), E. boliviensis (4,77%) and unidentified Eimeria specie (7,63%).

Hepatozoon spp. são os protozoários intracelulares mais frequentemente encontrados em serpentes. Tendo em vista a variedade de formas parasitando tais animais e as divergências dos dados encontrados em literatura, o objetivo deste estudo foi tentar separar espécies de Hepatozoon de serpentes, testando oligonucleotídeos que amplifiquem regiões genômicas menos conservadas, detectando diferenças entre as espécies, bem como realizar as caracterizações morfológicas, morfométricas e moleculares de Hepatozoon spp. de serpentes naturalmente infectadas. Para tal, foram utilizadas serpentes doadas ao Centro de Estudos de Venenos e Animais Peçonhentos (CEVAP) da Universidade Estadual Paulista de Botucatu que, em exames de rotina, mostraram-se positivos para tais parasitas. O sangue foi coletado por punção da veia caudal, foram confeccionados esfregaços sanguíneos e uma alíquota foi congelada a -20°C, para posterior extração do DNA. As caracterizações morfológicas e morfométricas foram realizadas utilizando um software especializado para análise de imagens. Dos 215 espécimes investigados, foram eleitos cinco exemplares de Crotalus durissus terrificus, nos quais foi visualizado um tipo de gamonte em cada espécime. Pela análise morfológica e morfométrica, estes gamontes foram agrupados em três populações. As alterações provocadas por tais parasitas, nas hemácias, também foram analisadas. Para a caracterização molecular das espécies de Hepatozoon através de sequenciamento genético, foram testados sete pares de oligonucleotídeos que amplificam regiões distintas do gene rDNA utilizando-se a técnica da PCR. Os testes realizados apontaram os pares de oligonucleotídeos HepF300/Hep900 e HEMO1/HEMO2 como eficientes em amplificar e caracterizar regiões genômicas Hepatozoon spp. de serpentes...
Hepatozoon spp. are the most frequent intracellular protozoa found in snakes. Given the variety of forms parasitizing these animals and differences of the data found in literature, the aim of this study was to attempt to separate Hepatozoon species of snakes, testing oligonucleotides that amplify less reliable genomic regions, detecting differences among species, as well as perform the morphological, morphometric and molecular characterization of Hepatozoon spp. of naturally infected snakes. For this purpose, were used snakes donated to Center for the Study of Venoms and Venomous Animals of the São Paulo State University/Botucatu (CEVAP) that, in routine were detected positive for such parasites. Blood was collected by the tail vein puncturing, blood smears were prepared and an aliquot was frozen at -20° C for subsequent DNA extraction. The morphological and morphometric characterization were performed by using a specialized image analysis software. Of the 215 investigated animals, five specimens of Crotalus durissus terrificus were elected, in which were found five parasitic forms that, by morphometric analysis, were grouped into three populations. The changes caused by these parasites in red blood cells were also analyzed. For the molecular characterization of Hepatozoon species through genetic sequencing, were tested seven pairs of primers that amplify different regions of the rDNA gene using the PCR technique. Only the primers HepF300/Hep900 and HEMO1/HEMO2 were efficient in amplifying and characterizing genomic regions of snakes Hepatozoon spp.. The best results were achieved when the sequences amplified from the both primers were analyzed together and the results were associated with the morphology and...

Abstract:

In 1930 the university Diploma in Tropical Veterinary Medicine was instituted as a postgraduate course for Colonial Veterinary Officers. It was not taught during the war but resuscitated in 1954. In 1962 a Tropical Unit was formed in the Department of Animal Health, funded by the Ministry of Overseas Development. Students came from 44 countries. In 1970 the CTVM was officially opened. Additional tropical courses were developed but cuts in Government spending created problems. Tuition fees had to cover costs. In the 1980s students came from 74 countries. In the 1990s research on protozoology, helminthology, microbiology and animal husbandry were largely based in the tropics. Publications and short courses were developed. Students (1,158) from 109 countries graduated from the CTVM before it ceased to function by 2005.
