Occurrence of Ehrlichia canis and Anaplasma platys in household dogs from northern Parana

Abstract: Canine monocytic ehrlichiosis caused primarily by Ehrlichia canis and canine thrombocytic anaplasmosis induced by Anaplasma platys are important emerging zoonotic tick-borne diseases of dogs. There is evidence that these pathogens can also affect humans. This study evaluated the presence of E. canis and A. platys in blood samples collected from 256 domiciled dogs in the municipality of Jataizinho, located in north region of the State of Parana, Brazil, by PCR assay. The occurrence of E. canis and A. platys was… Show more

“…These results largely contrast to all other regions of Brazil that have been investigated, where recent studies have indicated, by molecular methods, that a considerable proportion of the dogs was infected by E. canis, A. platys, B. vogeli, and/or H. canis (RAMOS et al, 2010;SPOLIDORIO et al, 2011;VIEIRA et al, 2011;COSTA-JÚNIOR et al, 2012;SILVA et al, 2012;DEMONER et al, 2013). Indeed, these results are directly related to the absence of infestations by R. sanguineus s.l.…”

“…Many recent studies have shown that canine babesiosis (caused by Babesia vogeli), hepatozoonosis (caused by Hepatozoon canis), monocytic ehrlichiosis (caused by Ehrlichia canis), and anaplasmosis (caused by Anaplasma platys) are endemic in many parts of the country (RAMOS et al, 2010;SPOLIDORIO et al, 2011;VIEIRA et al, 2011;COSTA-JÚNIOR et al, 2012;SILVA et al, 2012;DEMONER et al, 2013). While H. canis seems to be primarily associated with ticks of the genus Amblyomma in Brazil (FORLANO et al, 2007;DEMONER et al, 2013), the other agents mentioned above have been associated with Rhipicephalus sanguineus sensu lato ticks (DANTAS-TORRES, 2008;VIEIRA et al, 2011).…”

“…In the past various studies have been carried out regarding the molecular prevalence of E. canis worldwide and the prevalence rate has been reported to range from 3.1% to 88.0% (Murphy et al 1998;Dagnone et al 2003;Bulla et al 2004;Macieira et al 2005;Diniz et al 2007;Carvalho et al 2008;Alexandre et al 2009;Dagnone et al 2009;Faria et al 2010;Silva et al 2012). As regards the Indian scenario, a small number of published reports are available: the prevalence of E. canis was reported to be 50% (49/98) in Chennai (Lakshmanan et al 2007) and 20.6% from four different regions of India (Abd Rani et al 2011).…”

“…Further, correlation of various risk factors viz. age, sex, breed of host and season with the prevalence of the disease has been documented in past Lakshmanan et al 2006;Singh et al 2011;Silva et al 2012) but similar reports from this part of the country using molecular assays are lacking. Therefore, the current study was undertaken to investigate the PCR-based prevalence of infection and its correlation with various risk factors.…”

“…Anaplasma platys has been molecularly detected in dogs in the states of from Mato Grosso do Sul (DAGNONE et al, 2009), São Paulo (DAGNONE et al, 2009), Pernambuco (RAMOS et al, 2010 and Paraná (SILVA et al, 2012). The percentage of A. platys positive samples by PCR assay in our study (1.6%) was lower than that found by Dagnone et al (2009) (45%) in dogs of Campo Grande, MS, probably because all the dogs sampled in the earlier study showed clinical signs of tick-borne diseases and the presence of intracytoplasmic inclusion bodies in leucocytes and platelets.…”
