Summary
The prevalence of drug-resistant parasites in goats in West Malaysia has rarely been reported. Ten commercial goat farms were surveyed for resistance to anthelminthics by measuring the reduction in faecal egg counts (FECs) after treatment with levamisole, pyrantel pamoate and fenbendazole. Resistance to fenbendazole was seen in most farms; there was no evidence of resistance to levamisole but some resistance to pyrantel pamoate was detected on one farm. The significance of the findings are discussed.
Résumé
La prévalence de parasites résistant aux médicaments chez des chèvres a rarement été rapportée en Malaisie. Une enquête a été réalisée sur les chèvres de dix élevages commerciaux pour déterminer la résistance aux anthelminthiques en mesurant la réduction du nombre d'oeufs dans les fèces après traitement avec du levamisole, du pamoate de pyrantel et du fenbendazole. Les animaux de la plupart des élevages ont montré une résistance au fenbendazole mais non au levamisole alors que ceux d'un élevage ont résisté à l'action du pamoate de pyrantel. Les raisons de ces observations sont discutées.
Resumen
Se ha informado pocas veces de la existencia de resistencia a los antihelmínticos en cabras en Malasia Occidental. Debido a esto, se monitorearon 10 granjas comerciales, midiendo la reducción en el conteo fecal de huevos después del tratamiento con levamisol, pamoato de pirantel y fenbendazol. La resistencia contra fenbendazol fue evidente en todas las granjas; no hubo evidencia de resistencia a levamisol, pero se encontró alguna resistencia a pamoato de pirantel en una de las granjas estudiadas. Se discuten el significado de estos hallazgos.
