Abstract

Anaplasmosis is known for causing anemia in cattle. However, morphological changes in the red and white blood cells are not often described in bovine anaplasmosis cases. Thus, the aim of this work was to describe changes in blood cell morphology, such as the incidence of basophilic stippling in red ...

Abstract

Anaplasmosis is a worldwide hemolytic disease in cattle caused by a gram-negative obligatory intracellular bacterium, characterized by anemia and jaundice. Among the treatments used for anaplasmosis is a drug called imidocarb dipropionate, also indicated as an immunomodulator agent. However, it...

Abstract

Rhipicephalus microplus is a vector of cattle tick fever, a disease caused by the protozoans Babesia bovis and B. bigemina, and also anaplasmosis, produced by the Rickettsiales Anaplasma marginale. These tick-borne pathogens cause considerable losses to Brazilian livestock breeders and represent an ...
