ABSTRACT

Se describe un caso de posible resistencia al fenbendazol en una ternera Jersey infestada por Dictyocaulus viviparus. En el municipio de Entrerríos (Antioquia, Colombia), una hembra de la raza Jersey de 6 meses de edad, presentó un serio cuadro de bronco-neumonía, el cual no mejoró con la aplicación de fenbendazol y enrofloxacina como terapia de mantenimiento. En la necropsia, se observó un número elevado de parásitos vivos compatibles con Dictyocaulus viviparus, determinando una bronquitis verminosa. Este nematodo, el cual se trata rutinariamente con fenbendazol en las fincas lecheras colombianas, ha demostrado ser resistente frente algunos bencimidazoles; finalmente, se señalan las posibles causas de esta resistencia de Dictyocaulus viviparus en la ternera Jersey.


It describe the clinical case of a possible resistance to fenbendazole in a Jersey calf infested by Dictyocaulus viviparous described. In the municipality of Entrerrios (Antioquia, Colombia) a female Jersey breed of 6 months of age, presented serious sings of bronchopneumonia. which did not improve with the application of fenbendazole and enrofloxacin as maintenance therapy. At the necropsy, a large number of live parasites compatible with Dictyocaulus viviparus were observed, determining a verminous bronchitis. This nematode, which is routinely treated with fenbendazole in Colombian dairy farms, has been proved resistance when is trated with some benzimidazoles. This specific case shows the possible causes of the Dictyocaulus viviparus resistance in Jersey calf.

ABSTRACT

A neosporose tem grande importância em bovinos, e sua patogênese neste hospedeiro, em termos gerais, está esclarecida, porém, em equídeos é pobremente conhecida. Na Colômbia ainda não foram reportados anticorpos Anti-Neospora spp. em equídeos, sendo assim objetivou-se no presente estudo avaliar a ocorrência do parasito em jumentos (Equus asinus) de fazendas que apresentavam risco da doença nestes animais. Foram utilizados 56 animais no estado de Sucre (Colômbia), escolhidos aleatoriamente dentro das fazendas selecionadas. Utilizou-se um peptídeo recombinante originado de Neospora caninum (NcGRA1) para o diagnóstico por Dot-ELISA, e o soro foi diluído em 1:200. Este estudo reporta, pela primeira vez no estado de Sucre e na Colômbia, a presença de anticorpos anti-Neospora spp. na espécie Equus asinus, com uma ocorrência de 19,7% (11/56) dos animais amostrados...


The neosporosis has great importance in cattle, and its pathogenesis in this host has been generally clarified, however, in horses, neosporosis is poorly known, and in Colombia anti-Neospora spp antibodies have not been reported. Therefore, the main objective in the present study was to evaluate the occurrence of this parasite in donkeys (Equus asinus) from farms that presented a risk of disease in these animals, as well as no health plan for them. Were used 56 animals randomly chosen inside selected farms in the state of Sucre (Colombia). A recombinant peptide originated from Neospora caninum (NcGRA1) was used for the diagnosis with Dot-ELISA and serum was diluted 1:200. This study is the first to report the presence of anti-Neospora spp. in donkeys (Equus asinus) in the state of Sucre, and in Colombia. The occurrence was in 19.7% of the animals sampled (11/56)...
