Abstract [en]

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.

Introducción: Los micoplasmas hemotrópicos se encuentran ampliamente distribuidos envarias regiones del mundo. El presente trabajo tuvo como objetivo determinar la presencia deespecies de micoplasmas hemotrópicos en bovinos, bufalinos, perros y garrapatas de Cuba.

Métodos: Se analizaron 39 muestras de sangre de búfalos y 41 bovinos para investigar lapresencia de Mycoplasma wenyonii y ‘Candidatus Mycoplasma haemobos’; 391 muestrasde sangre de perros y 247 pools de garrapatas para detectar la presencia de Mycoplasmahaemocanis y ‘Candidatus Mycoplasma haematoparvum’ mediante ensayos de PCR en tiemporeal TaqMan® (especie específicos).

Resultados: Para M. wenyonii 53 animales fueronpositivos y 33 para ‘Ca. Mycoplasma haemobos’; en coinfección con M. wenyonii, con prevalenciassimilares en bovinos y bufalinos. El 17,9 % de las muestras de perros fueron positivaspara al menos una especie de hemoplasma, con el 15,1 % positivo para M. haemocanis, el4,4 % para ‘Ca. Mycoplasma haematoparvum’, y el 1,5 % coinfectados. Las garrapatas seidentificaron como Rhipicephalus sanguineus sensu lato; y ninguno de los pools fue positivoa las especies de micoplasmas caninos en estudio. Se demostró la presencia de 5 haplotiposdiferentes para M. haemocanis y 4 haplotipos para ‘Ca. M. haematoparvum’; uno de estoshaplotipos mostró 100 % de identidad con un aislado de Granada, que se asoció con casosde exposición zoonótica.

Conclusiones: Estos resultados constituyen la primera evidencia molecular de la infección por especies de hemoplasmas en bovinos y bufalinos de Cuba y elCaribe y el primer reporte molecular de la ocurrencia de infecciones simples y coinfeccionescausadas por M. haemocanis y ‘Ca. M. haematoparvum’ en perros de Cuba. Por primera vezse evidencia la circulación de un genotipo de ‘Ca. M. haematoparvum’ con potencial zoonótico,común entre las Antillas mayores y menores del Caribe.
