TRIPANOSSOMÍASE EM BOVINOS LEITEIROS DO MUNICÍPIO DE MORRINHOS - GO: RELATO DE CASO

Abstract

Trypanosomiases are diseases caused by unicellular protozoa belonging to the genus Trypanosoma, which can infect humans, domestic and wild ungulate animals. In Brazil, Trypanosoma vivax is the species considered to be the most pathogenic and of greatest economic interest, responsible for considerable losses in ruminant production. The occurrence of the disease in endemic areas is related to the presence of vectors, displacement and introduction of animals into herds, iatrogenic transmission and the pathogenicity of the agent. Trypanosomiasis does not present pathognomonic clinical signs, so it is crucial the laboratory diagnosis through parasitological, serological and molecular methods. The differential diagnosis is necessary because the symptoms are similar to other diseases that affect cattle. The treatment can be preventive or curative, depending on the epidemiological characteristics of each region. The trypanocide drugs available in Brazil to be used in the treatment and prophylaxis of the disease are: Diminazene Diaceturate and Isometamidium Chloride. The objective of the present study was to report the occurrence of trypanosomiasis in five Dutch cows, treated in a dairy farm in the municipality of Morrinhos-Go. The response of the animals to treatment with isometamidium chloride was effective in controlling parasitemia and remission of clinical signs.
