NATURAL INFECTION BY GASTROINTESTINAL AND BRONCHOPULMONARY NEMATODES IN MOUFLONS (OVIS MOSIMON) AND THEIR RESPONSE TO NETOBIMIN TREATMENT

Gastrointestinal and bronchopulmonary nematode infections and the effi cacy of netobimin (Hapasil(R)) were analyzed by way of fecal examinati on in 10 female mouflons (Ovis musimon), in central Spain, February 19 93. Before treatment all 10 mouflons had Trichostrongylus axei, Telado rsagia circumcincta and Marshallagia spp.; six had Nematodirus spp., t wo had Trichuris sp., one had Capillaria sp., seven had bronchopulmona ry Dictyocaulus filaria and 10 mouflons had protostrongylid lungworms (Muellerius capillaris, Protostrongylus rufescens, Cystocaulus ocreatu s or Neostrongylus linearis). Netobimin (7.5 mg/kg) was 100% effective against T. axei, T. circumcincta, Marshallagia spp., and D. filaria i nfections whereas one animal continued eliminating Nematodirus spp. eg gs. The drug also was effective against Capillaria spp. but not agains t Trichuris spp. or protostrongylid infections.
