Concomitant Babesia gibsoni and Ehrlichia canis infection in a dog

Experimental transmission of Babesia gibsoni in a dog, in a state of subclinical infection by Ehrlichia canis, resulted in a severe concomitant infection of E. canis and B. gibsoni characterized by neurological signs, including nystagmus and seizures. Mononuclear cells harbouring the characteristic morulae of E. canis were numerous in lung impression smears. B. gibsoni were observed in the peripheral blood in erythrocytes and within macrophages in spleen, liver and kidney impression smears. Erythrocytes were found trapped within capillaries of the brain. B. gibsoni were seen in various stages of division and on average 16 merozoites were seen in a single infected erythrocyte.
