Abstract

Thirty naturally infected dogs were divided into three groups (10 animals each): group I (canine leishmaniosis), group II (canine ehrlichiosis) and group III (dogs co-infected by both infectious agents). Ten clinically healthy dogs were used as controls. A haematological profile was obtained and dog sera were assessed for the presence of platelet-bound IgM and IgG antibodies (PBIgM, PBIgG) using flow cytometry. Eight of the naturally co-infected dogs (80%), five of the leishmaniotic dogs (50%) and six of the ehrlichiotic dogs (60%) had detectable levels of platelet-bound antibodies (PBIg). No PBIg were observed in the control group. The hypothesis that Leishmania and Ehrlichia co-infection could more severely affect the immune response of infected dogs is discussed.
