Abstract

The Brazilian Northeast area is known for the caprineculture, whose main problem is the gastrointestinal nematodes, and the control of the parasites has been jeopardized by the anthelmintic resistance. The purpose of this study was to verify the sensibility of the goat nematodes to the activity of the substances ivermectin 1% and albendazole 10%. The work was carried out in 30 goat herds located in the city of Mossoró, Rio Grande do Norte, Brazil, within January and November, 2008. In each property, 45 animals were selected and divided into three groups (one control and two treatments). The geographical coordinates of all the properties were obtained by GPS. The obtained data were analyzed by the statistical program RESO. The animals received the vermifude and 10 days after-treatment feces were collected. In the studied properties, the Haemonchus contortus showed greater prevalence in all the treated groups, 90% of the helmints population was resistant to albendazole and 36.6% to ivermectina. Trichostrongylus sp. was found in 70% of the properties and its percentile of the helmint population resistant to ivermectina and to albendazole was of 33.3% and 42.8%, respectively. The reduction in the egg counting in the feces (RECF) after 10 days of treatment with ivermectina and albendazole varied within 43% and 100%, and within 29% to 100%, respectively. The profile of the properties demonstrated that the anthelmintic most commonly used were from the following groups: benzimidazol (63.3%), ivermectin (33.3%), and imidazol (3.3%).
