Resumo: | ABSTRACT Ehrlichia infections in cattle are frequent in Africa but have also been reported in Brazil and North America. This paper reports natural infection by Ehrlichia sp. associated with Babesia bigemina and Anaplasma marginale in a calf in the municipality of Campo Grande, state of Mato Grosso do Sul, Brazil, presenting polioencephalomalacia. The molecular evidence, based on a fragment of the dsb gene, indicates a species of Ehrlichia genetically related to Ehrlichia canis and other species of the genus found in the tick Rhipicephalus (Boophilus) microplus and a calf from Brazil (99 to 100% identity). It was not possible to associate the clinical signs with Ehrlichia infection due to co-infections and histological evidence of another disease. However, the circulation of the bacteria in bovines in Brazilian Cerrado was confirmed and more attention should be given to clinical suspicion of tick-borne pathogens in cattle to clarify the pathogenic potential of Ehrlichia sp.
