ABSTRACT

A 12-month-old mule (sterile hybrid equine species) presented unspecific neurological changes (symmetric ataxia, dysmetria, conscious proprioceptive deficit and weakness). Due to poor prognosis and to the fact that a sibling from the previous generation exhibited similar clinical signs that were not definitively diagnosed, the animal was euthanized. Diagnosis of neuroaxonal dystrophy was confirmed by anatomohistopathological analysis. This is the first clinical case of neuronal dystrophy in a mule reported in the world. The clinical and histopathological characteristics of this disease were very similar to those reported for several equine breeds. Therefore, the disease should also be considered in the diagnosis of neurological conditions in mules and donkeys.(AU)


Relata-se o caso de uma mula de 12 meses que apresentou alterações neurológicas inespecíficas (ataxia simétrica, dismetria, déficit proprioceptivo consciente e fraqueza). Devido ao mau prognóstico e ao fato de um irmão da geração anterior apresentar sinais clínicos similares sem diagnóstico conclusivo, o animal foi eutanasiado. O diagnóstico de distrofia neuroaxonal foi confirmado por análise anátomo-histopatológica. Esse é o primeiro caso clínico de distrofia neuroaxonal em muar relatado no mundo. As características clínicas e histopatológicas dessa doença foram muito semelhantes às relatadas em várias raças de equinos. Portanto, a doença também deve ser considerada no diagnóstico de condições neurológicas em muares e asininos.(AU)

ABSTRACT

Abstract The objective of this study was to determine the parasitological profiles of traction equids from the semi-arid climate of Paraíba (PB) State. We analyzed 96 equids that performed traction work, with no defined breed, males and females, and all older than 24 months. Among the analyzed animals, 51% were donkeys, 41.7% mules, and 7.3% horses. Fecal material and blood were collected for parasitological examination and to determine the packed cell volume (PCV), respectively. The samples were sent to the Veterinary Parasitology Laboratory, Veterinary Hospital - IFPB, Sousa-PB campus, and epidemiological questionnaires were provided to the owners. It was observed that 83.3% of equids tested positive for gastrointestinal parasites. Strongylidae was the most prevalent parasite (83.3%), followed by Giardia sp. (5.3%), and Eimeria sp. (2.1%). The mean eggs per gram (EPG) value of the fecal samples was 1143. Fecal analysis revealed that 78.9% of the larvae were from "small strongyles". The presence of ectoparasites was not observed in the studied animals. The answers to our questionnaire revealed that 69.8% of the animals had never been dewormed and that the remaining 31.2% had only been dewormed once. We concluded that the prevalence of gastrointestinal parasites among traction equids in the municipality of Sousa-PB is high.


Resumo Objetivou-se determinar o perfil parasitológico de equídeos carroceiros no município de Sousa, Sertão da Paraíba. Foram analisados 96 equídeos que realizavam trabalho de tração, sem raça definida, machos e fêmeas, idade superior a 24 meses. Dentre os animais analisados 51% foram asininos, 41,7% muares e 7,3% equinos. Foi coletado material fecal para exames coproparasitológicos e sanguíneo para determinação do volume globular (VG), encaminhados ao Laboratório de Parasitologia Veterinária, Hospital Veterinário - IFPB, campus Sousa-PB. Foi aplicado questionários epidemiológicos aos proprietários. Observou-se que 83,3% dos equídeos carroceiros foram positivos nos exames parasitológicos fecais. Os Estrongilídeos foram os parasitos mais prevalentes (83,3%), seguidos por Giardia sp. (5,3%). e Eimeria sp. (2,1%). A média de OPG dos equídeos carroceiros foi 1143. Nas coproculturas, constatou-se que 78,9% das larvas eram de "pequenos estrôngilos". Não foi observada a presença de ectoparasitas. Em 69,8% dos animais nunca haviam sido vermifugados e os demais 31,2% apenas uma vez. Concluiu-se que é alta a prevalência de parasitos gastrintestinais em equídeos carroceiros do município de Sousa-PB.

ABSTRACT

A anemia infecciosa equina (AIE) é uma doença causada por um lentivirus que possui distribuição mundial. Essa enfermidade é um entrave ao desenvolvimento da equinocultura no Brasil devido à obrigatoriedade de eutanásia dos animais positivos. Este trabalho teve como objetivo estimar a prevalência de AIE em equídeos de tração no Distrito Federal, assim como identificar fatores de risco associados à doença. Foram sorteados aleatoriamente 350 proprietários (Unidades Primárias de Amostragem- UPA) e foram amostrados todos os equídeos (Unidades secundárias de Amostragem) de cada proprietário sorteado, totalizando 496 animais. As amostras sanguíneas foram analisadas no Lanagro/MG por meio da técnica de imunodifusão em ágar gel (IDGA). No momento da coleta de sangue, também foi aplicado um questionário epidemiológico para a análise de possíveis fatores de risco. A prevalência de AIE nas UPA foi estimada em 2,29%, (IC 95%: 1,01-4,2%) e nos animais foi de 1,81% (IC 95%: 0,55-3,07%). A prevalência foi significativamente maior em muares do que em equinos. Não foi possível comprovar a presença de nenhum outro fator de risco associado à doença. Este estudo demonstra que a prevalência da AIE em equídeos de tração é baixa no Distrito Federal, porém mais alta do que os dados de vigilância de rotina sugerem, o que justifica a eutanásia dos equídeos reagentes, com a finalidade de promover a erradicação da enfermidade. Ratifica-se a importância da realização de exames periódicos nesses animais e a manutenção das atividades de vigilância.(AU)


Equine Infectious Anaemia (EIA) is a disease that has worldwide distribution and it is caused by a lentivirus. The disease constrains the development of horse breeding in Brazil, leading to compulsory slaughter of test positive animals. The objective of this study was to estimate the prevalence of EIA in traction equids and identify potential risk factors in the Federal District. Three hundred and fifty (350) owners were randomly selected (Primary Sampling Units-PSU) and all equids (Secondary Sampling Units - SSU) from each owner were sampled, in a total of 496 animals. Blood samples were tested in LANAGRO/MG using the agar-gel immunodiffusion test (AGID). An epidemiological questionnaire was used to collect data on potential risk factors associated with the disease. The prevalence of PSU (owners) was estimated at 2.29% (95% CI: 1.01-4.2%) and the prevalence in animals was 1.81% (95% CI: 0.55-3.07%). Prevalence was higher in mules than in horses. None of the other variables analyzed as potential risk factors was associated to the presence of the disease. The present study demonstrated that the prevalence of EIA in traction equids is low in the Federal District, which strengthens the case for the maintaining the test-and-cull policy and the need for disease surveillance measures aimed at eradicating the disease.(AU)

ABSTRACT

Abstract Brazilian spotted fever (BSF) is a fatal zoonosis because of the difficulties in its early diagnosis and treatment. Occurrences of BSF in the northeast of the state of Paraná prompted investigation of areas at risk of this rickettsiosis in the municipalities of Japira, Jaboti, Pinhalão and Tomazina. To determine the areas at risk, 592 serum samples from dogs and 230 from equids were analyzed by means of the indirect immunofluorescence assay (IFA) for Rickettsia rickettsii and R. parkeri . In addition, risk probability maps were drawn up using the kriging indicator technique. Among the samples tested, 5.3% (43/822) indicated presence of antibodies reactive to at least one of the two Rickettsia species tested: 7.8% of the equids (18/230) and 4.2% of the dogs (25/592) were positive. Geostatistical analysis showed that the average seropositivity rate was 5 to 6%. Although the average seropositivity rates observed among these dogs and equids were lower than those reported from endemic areas of Brazil, the biotic components (etiological agent, vector and reservoirs) and environmental aspects of BSF epidemiology were present in these municipalities.


Resumo A febre maculosa brasileira (FMB) é uma zoonose fatal devido às dificuldades para diagnosticá-la e tratá-la precocemente. A ocorrência de casos de FMB no Estado do Paraná suscitou a investigação de áreas de risco desta rickettsiose nos municípios de Japira, Jaboti, Pinhalão e Tomazina, na mesorregião norte pioneiro do Paraná. Para determinar as áreas de risco foram analisadas amostras de soro de 592 cães e 230 equídeos submetidos à reação de imunofluorescência indireta para Rickettsia rickettsii e R. parkeri. Além disto, foram construídos mapas de probabilidade de risco pela técnica de krigagem indicatriz. Das amostras testadas 5,3% (43/822) continham anticorpos para pelo menos uma das duas rickettsias testadas. Os equídeos apresentaram uma positividade de 7,8% (18/230) e os cães de 4,2% (25/592). A análise geoestatística mostrou que a soropositividade média é de 5 a 6%. Embora as soropositividade médias de cães e equídeos constatadas tenham sido menores do que as relatadas em áreas endêmicas do território brasileiro, os componentes bióticos (agente etiológico, vetor e reservatórios) e ambientais da epidemiologia da FMB se fazem presentes nos municípios referidos.

ABSTRACT

The hematological parameters and total protein concentration in healthy donkeys during pregnancy, under grass handling conditions in tropical weather, were evaluated. Fifth-two Marchador Brasileiro breed healthy donkeys, ranging from 8 to 16 years old, were evaluated, 36 of which were pregnant. The animals were separated in four groups: non pregnant (control), pregnancy from 25 to 110 days (first phase), from 111 to 210 days (second phase), and from 211 to 340 days (third phase). Total protein, erythrocyte, and leukocytes counts; packed cell volume; hemoglobin concentration; hematimetric absolute rates of mean corpuscular volume (MCV); mean corpuscular hemoglobin (MCH); and mean corpuscular hemoglobin concentration (MCHC) were evaluated. Total protein and eosinophils count decreased in the first phase. Red blood cells, hemoglobin concentration, and MCHC increased in the third phase of pregnancy. However, MCV and MCH decreased in the same phase.

ABSTRACT

Five healthy adult male Iranian donkeys [Equus asinus] were selected and Ivermectin [0.2,0.6 and 0.9 mg/kg, orally at different times] for 14 days was administered. Before dosing, control blood samples were taken on day 0. Blood samples were taken on days 1,2,3,7 and 14 following ivermectin administration at different doses. The results showed that the activity of serum AST and LDH increased on days 7 and 14 following ivermectin [0.2, 0.6 and 0.9 mg/kg, orally] administration [p<0.05]. ALP activity and BUN concentration increased significantly on day 14 following ivermectin [0.2, 0.6 and 0.9 mg/kg, orally] administration [p<0.05]. Changes of ablumin, creatinin,glucose, total protein, Phosphorous and calcium concentrations and hemoglobin, PCV, MCH, MCHC, MCV and percentages of neutrophils, eosinophils, monocytes, lymphocytes and platelet numbers were not significant [p>0.05]. As it was shown in short term, no abnormal clinical and laboratory findings were detected following different oral doses of ivermectin and it seems that the drug can be safely administered to this species
