Resumo: Helmintosis is one of the main sanitary problems of modern sheep raising whereas the resistance to anthelmintic is a severe impend for its control. With the objective of verifying the phenomenon in relation to albendazole, ivermectin and moxidectin in the region of Londrina, Parana, Brazil, 850 animals from 10 properties were selected, from January to March 1997. These animals were distributed in four randomic groups, T1-albendazole, T2-ivermectin, T3-moxidectin and T4-control, and were monitored by the method of counting eggs by each gram of faeces in order to obtain the percentage of reduction in the average of gastrintestinal nematod's eggs. The results showed that anthelmintic resistance occurred in all properties with percentages of 100, 80 and 20% for albendazole, ivermectin and moxidectin, respectively. Through the analysis oflarvas's culture it was observed that Haemonchus spp. was the most frequent type of nematodes and, probably, the major reason for the resistance to the drugs used in the experiment.

Com o objetivo de verificar a resistência frente ao albendazole, ivermectin e moxidectin, na região de Londrina, Paraná, Brasil, foram selecionados 850 animaisde 10 propriedades, no período de janeiro a março de 1997. Estes ovinos foram distribuídos aleatoriamente em quatro grupos, T1- albendazole, T2 - ivermectin, T3 - moxidectin e T4 - controle, e monitorados pelo método de contagem de ovos por grama de fezes para obtenção do índice percentual da redução da média de ovos de nematóides gastrintestinais. Os resultados apresentados demonstraram que a resistência a anti-helmínticos ocorreu em todas as propriedades com percentual de 100, 80 e 20%, respectivamente, para o albendazole, ivermectin e moxidectin. Pela análise das culturas de larvas, observou-se que o Haemonchus spp. foi o gênero de nematóide mais freqüente e, possivelmente, o principal responsável pela resistência às drogas utilizadas no experimento.  UEL2009-01-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/501110.5433/1679-0359.1998v19n1p31Semina: Ciências Agrárias; Vol. 19 No. 1 (1998); 31-37Semina: Ciências Agrárias; v. 19 n. 1 (1998); 31-371679-03591676-546Xreponame:Semina.
