Abstract: The current study evaluated the prevalence of Ehrlichia canis Donatien and Lestoquard in domestic dogs, Canis familiaris L., and Rhipicephalus sanguineus (Latreille) (Acari: Ixodidae) ticks from different areas of Brazil. In Monte Negro County (state of Rondônia, Brazilian western Amazon), the indirect immunofluorescence assay detected E. canis-reactive antibodies (titer > or = 40) in 58/153 (37.9%) and 40/161 (24.8%) dogs from the urban and rural areas, respectively. These values were significantly different … Show more

“…In the Monte Negro district of the State of Roraima, utilizing a randomly-selected sample of the urban area, Aguiar et al (2007b) obtained a prevalence rate of 37.9% (58/153) similar to the one observed in the present study. In another study, conducted by Carlos et al (2007) in two cities in the Southwestern region of the State of Bahia, Itabuna and Ilhéus, the infection rate was 36% (72/200), also similar to that of the present study; it should be noted, however, that the dogs in the study by Carlos et al were chosen from animals receiving clinical care.…”

“…There are scarce data available regarding E. canis infection in R. sanguineus (MURPHY et al, 1998;UNVER et al, 2001;NDIP et al, 2007). In the study performed by Aguiar et al (2007b) in Monte Negro (State of Rondônia) and São Paulo (State of São Paulo), E. canis-infection rates in R. sanguineus ticks varied from 2.4 (4/165) to 6.2% (10/162). Results similar to those obtained in the present study were observed in Africa, where the infection rate was 21% (19/92), with the tick specimens examined having been collected from 15 dogs (NDIP et al, 2007).…”

“…Molecular methods demonstrated similar results for the effects of sex and age relative to infection by E. canis in Cuiaba, State of Mato Grosso (SILVA et al, 2010), and Ilheus and Itabuna, State of Bahia (CARVALHO et al, 2008). This pattern was also observed with serological assessments performed in several Brazilian cities: Cuiaba, State of Mato Grosso (SILVA et al, 2010), Monte Negro, State of Rondonia (AGUIAR et al, 2007), Patos, State of Paraiba (AZEVEDO et al, 2011), and southern cities in the State of Rio Grande do Sul (SAITO et al, 2008). Serological surveys made in the USA (RODGERS et al, 1989), Israel (HARRUS et al, 1997, and Japan (INOKUMA et al, 1999) revealed similar findings.…”

“…Canine ehrlichiosis has been reported from subtropical and tropical areas of the world where it is one of the very common disease reported during veterinary practice in dogs (Rani et al 2011). One of the major reasons for the common occurrence of E. canis is the tick vector, Rhipicephalus sanguineus sensu lato, which is common in rural and urban areas in tropical and subtropical areas of the world (Aguiar et al 2007;Dantas-Torres 2008;Aktas 2014;Aktas et al 2015). 1 These two authors have contributed equally to the manuscript.…”
