Molecular Investigation of Hemotropic Mycoplasmas in Human Beings, Dogs and Horses in a Rural Settlement in Southern Brazil

Abstract: SUMMARYThe aims of this study were to determine the prevalence of hemoplasmas in a rural Brazilian settlement's population of human beings, their dogs and horses, highly exposed to tick bites; to identify the tick species parasitizing dogs and horses, and analyze factors associated with their infection. Blood samples from 132 dogs, 16 horses and 100 humans were screened using a pan-hemoplasma SYBR green real-time PCR assay followed by a species-specific TaqMan real-time PCR. A total of 59/132 (44.7%) dog sampl… Show more

“…The overall prevalence of hemoplasmas in in our study was similar to the prevalence observed in rural dogs in southern Chile [21], and in rural or free-ranging dogs worldwide, such as Australia [77] and Brazil [78]. Rural environments were suggested to be a risk factor for hemoplasma infections when compared with urban environments [21,79], and, accordingly, in free-ranging compared with domestic pet dogs [80].…”

“…Although Mycoplasma spp. infection has previously been reported in dogs (Ramos et al, 2010;Valle et al, 2014;Vieira et al, 2015) and has been correlated with exposure to ticks and fleas in Brazil (Valle et al, 2014), our findings corroborate other reports from Brazil, Greece and Africa, which did not find any association between hemoplasma infection and ticks (Barker et al, 2010;Tennant et al, 2011;Vieira et al, 2015). Since the clinical examinations were limited to the time of sampling, it is possible that these dogs may have acquired and eliminated ticks before this time.…”

“…Hemotropic mycoplasmosis has been recognized in Brazil and has been reported in several wild canids and felids as well as in humans [379382]. Several species of hemotropic mycoplasmas have been detected in dogs and cats [308, 361, 382388]. The most predominant species in dogs is M. haemocanis , which has been recognized in South and Southeast Brazil.…”
