Efeitos dos imidazotiazóis (levamisol e tetramisol) sobre nematóides gastrintestinais de bovinos no Município de Lavras da Mangabeira no Cariri Cearense.

Abstract

Parasitic infections are among the major causes of economic losses in cattle in the world, with emphasis on the gastrointestinal helminthiasis, diseases that cause production losses because of morbidity, mortality , costs of prophylaxis and / or treatment and decreased productivity in interaction with stress nutritional , environmental , management and other health aspects. The intensive use of anthelmintics , underdosing , and misdiagnosis and lack of turnover pharmacological bases have caused a serious health problem , which is the resistance of nematodes to drugs . This study aimed to evaluate the sensitivity of gastrointestinal nematodes of cattle to anthelmintics in Lavras da Mangabeira, Ceara. Given the enormous resistance found in different wormers, this assessment has enormous economic importancia both for producers and for the health of animals. The sensitivity to anthelmintics was evaluated by testing the reduction of eggs per gram of feces made in the Laboratory of Parasitic Diseases of Domestic Animals (LPD) of the Academic Unit of Veterinary Medicine (UAMV) Health Center and Rural Technology (CSTR), University Federal de Campina Grande (UFCG). The results showed that there was resistance to gastrointestinal helminths of cattle anthelmintics (levamisole and tetramisole) after the 14th day after treatment. For the period of the day was the afternoon shift that occurred largest egg retrieval.
