Mycoplasma haemocanis (Mhc) and Candidatus Mycoplasma haematoparvum (CMhp) have been described in dogs. Historically, microscopic visualization of hemotropic Mycoplasma spp. has occurred most often in immunocompromised or splenectomized dogs. The aim of this study was to determine the Mhc and CMhp prevalences among dogs from the United States. Novel 16S rRNA and RNAseP gene PCR assays were used to amplify hemotropic Mycoplasma species DNA for GenBank sequence alignment. Among the study population, hemoplasma prevalence was 1.3% (7 out of 506), with Mhc and CMhp prevalences of 0.6% and 0.8%, respectively. Two of six CMhp-infected dogs were co-infected with a Bartonella sp., and a third dog was seroreactive to Bartonella henselae antigens. The prevalence of Mhc and CMhp in this study was low; potential blood donors should be screened; and dogs and people can be co-infected with hemoplasma and Bartonella spp.
