Two hemoplasma species are known in dogs: Mycoplasma haemocanis (Mhc) and 'Candidatus Mycoplasma haematoparvum' (CMhp). Although their transmission routes are poorly understood, Rhipicephalus sanguineus has been suggested as a potential tick vector. The aim of the present study was to assess the prevalence, risk factors, and clinical importance of canine hemoplasmas in countries with a Mediterranean climate where R. sanguineus is highly prevalent using TaqMan real-time PCR, and to molecularly characterize the identified isolates. DNA (canine glyceraldehyde-3-phosphate dehydrogenase) was successfully amplified from all samples collected from 850 dogs in Italy, Spain, and Portugal, and 82 (9.6%) were PCR-positive for canine hemoplasmas (43 Mhc, 34 CMhp and 5 co-infected). The hemoplasma sample prevalence was significantly higher in Portugal (40%) than in Italy (9.5%) and Spain (2.5%). Risk factors for infection included living in kennels, young age, crossbreeding, and mange infection. No association was found with anemia. Phylogenetic analyses of the 16S rRNA and RNase P genes revealed >99% identity to other European isolates. In conclusion, canine hemoplasma infections were readily encountered in Mediterranean countries. The climate and living conditions seemed to influence canine hemoplasma prevalence. The clinical importance of canine hemoplasma infections appeared to be low, but the infection stage of the presented dogs was unknown.

Hemotropic mycoplasmas (hemoplasmas) are cell-wall deficient, epierythrocytic bacteria that cause infectious anemia in several mammalian species. The prevalence of hemoplasma species was examined by screening and species-specific PCR using blood samples collected from 51 sika deer in Hokkaido, Japan. Molecular analyses were performed for the 16S rRNA, 23S rRNA and RNase P RNA (rnpB) gene sequences. A total of 23/51 (45%) deer DNA samples were positive for hemoplasmas in the screening PCR. Using species-specific PCR, 12 and 17 samples were positive for 'Candidatus Mycoplasma haemocervae' and 'Candidatus M. erythrocervae', respectively. Sequencing and phylogenetic trees of those three genes indicate that the 'Candidatus M. haemocervae' and 'Candidatus M. erythrocervae' detected in Japanese deer are potentially different species from the cervine hemoplasma found in deer from America and Brazil.
