Introduction: Hemotropic mycoplasmas are widely distributed in several regions of the world. The aim of the present work was to determine the presence of hemotropic mycoplasma species in cattle, buffaloes, dogs and ticks in Cuba.
Methods: They were analyzed thirty-nine buffalo and 41 cattle blood samples to investigate the presence of Mycoplasma wenyonii and 'Candidatus Mycoplasma haemobos'. They were analyzed and 391 dog blood samples and 247 tick pools to detect the presence of Mycoplasma haemocanis and 'Candidatus Mycoplasma haematoparvum'. In all cases it was used the species-specific TaqMan® real-time PCR assay.
Results: For M. wenyonii 53 animals were positive and 33 for 'Ca. Mycoplasma haemobos'; in coinfection with M. wenyonii, with similar prevalence in cattle and buffalo. 17.9% of dog samples were positive for at least one hemoplasma species, with 15.1% positive for M. haemocanis, 4.4% for 'Ca. Mycoplasma haematoparvum', and 1.5% co-infected. The ticks were identified as Rhipicephalus sanguineus sensu lato; none of the pools were positive for the canine mycoplasma species under study. It was demonstrated he presence of five different haplotypes for M. haemocanis and four haplotypes for 'Ca. M. haematoparvum'; one of these haplotypes showed 100 % identity with one isolated from Grenada, which was associated with cases of zoonotic exposure. Conclusions. These results constitute the first molecular evidence of infection by hemoplasma species in cattle and buffaloes in Cuba and the Caribbean and the first molecular report of the occurrence of single infections and co-infections caused by M. haemocanis and 'Ca. M. haematoparvum' in dogs in Cuba. For the first time is evident the circulation of a genotype of ‘Ca. M. haematoparvum' with zoonotic potential, common between the Greater and Lesser Antilles of the Caribbean.
