Hemoplasmas are epierythrocytic bacteria that infect mammals. Candidatus Mycoplasma haemoalbiventris was detected in white-eared opossums (Didelphis albiventris) from southern and central-western Brazil. The present study aimed at i) screening opossums for tick-borne (TBP) pathogens (Piroplasmida and Anaplasmataceae) and ii) detecting and characterizing hemoplasma species infecting opossums from Curitiba and Foz do Iguaçu cities in the Paraná State, southern Brazil. Thirty blood samples from white-eared opossums were evaluated by PCR assays. Animals were not infested by ectoparasites. The mammalian endogenous gapdh gene was consistently amplified in all samples. All opossums tested negative for Theileria/Babesia spp. and Ehrlichia/Anaplasma spp. by PCR based on 18S rRNA and 16S rRNA genes, respectively. A genus-specific PCR assay based on the 16S rRNA gene of hemoplasmas showed that three/13 (23.08%; CI 95% 8.18-50.26%) opossums from Foz do Iguaçu were positive for hemotropic Mycoplasma sp. All opossums from Curitiba tested negative for hemoplasmas. Sequencing of both the 16S and 23S rRNA genes revealed that the animals were infected by Ca. M. haemoalbiventris. Although Ca. M. haemoalbiventris is prevalent in opossums in Brazil, clinical signs associated with its infection and its putative vectors remain unknown.(AU)
