This report aims to discuss the occurrence of protozoan infestation in a Girolanda cattle herd in the state of Bahia / BA. Bovine trypanosomiasis is a severe disease that is harmful to cattle, inducing large productive and economic losses. The animals are affected by protozoa of the genus Trypanosoma spp...
Abstract Trypanosoma vivax infections cause nonspecific clinical signs in cattle associated with aparasitemic intervals, making disease diagnosis a challenge. In Brazil, diminazene aceturate and isometamidium chloride (ISM) are available to treat bovine trypanosomosis. The objective of this study was to ...

Abstract Trypanosoma (Duttonella) vivax is an important cause of economic losses among feedlot cattle. These losses are related to the morbidity, mortality, reproductive issues and decreased production. It is known that the clinical signs observed in infections by this protozoon are similar to other hemo...
