Babesia canis and Babesia rossi Co-infection in an Untraveled Nigerian Dog

Abstract

A sexually intact 6-month-old female Alsatian dog was presented to the Veterinary Clinic of the National Veterinary Research Institute, Vom, Plateau State, Nigeria, for the following complaints: anorexia, hemoglobinuria, fever, tick infestation and general malaise. Microscopy revealed piroplasms with a wide range of sizes (1–5 min length) in red blood cells, raising a suspicion of a co-infection with two or more Babesia species. Specific PCR assays for canine Babesia spp. and DNA sequencing revealed the presence of Babesia canis and Babesia rossi co-infection. This study constitutes the first report of co-infection with B. canis and B. rossi in the West African sub-region and the first report of autochthonous B. canis on the African continent. Practitioners should be aware of potential changes in the species/sub-species of Babesia causing canine babesiosis in this region.
