“…Age and gender was not associated with the risk of seropositivity among the canine population, a finding that is in agreement with most epidemiological studies (23)(24)(25)(26) . However, in studies with dogs older than one or two years of age, the dogs have a higher frequency of anti-B.…”

The aim of this study was to determine the prevalence of anti-Ehrlichia canis and anti-Babesia vogeli IgG antibodies in dogs and correlate this prevalence with risk factors to evaluate the relation of serological status to hematological findings. Blood samples of dogs attended from September 2011 to March 2012 at the veterinary hospital of the Federal University of Lavras, Brazil, were analyzed using an indirect fluorescence antibody test (IFAT). Of the total 160 dog serum samples, 23.7% (38 dogs; CI 95 17.7% -30.7%) were seropositive for E. canis, 40.0% (64 dogs; CI 95 40.0% -59.2%) for B. vogeli, and 5.6% (9 dogs) for both hemoparasites. None of the epidemiological variables showed a significant association (P>0.05) with seropositivity to E. canis and B. vogeli. Dogs seropositive for E. canis showed lower values for hematocrit (P<0.05). However, for the erythrogram, the platelet count, the leukogram and clinical signs, no significant difference (P>0.05) was observed between dogs that were seropositive and seronegative for E. canis or for B. vogeli. Serological results suggest that infection with E. canis and B. vogeli is endemic in the canine population in question, with a prevalence of the subclinical phase (asymptomatic) in dogs that are seropositive for ehrlichiosis or babesiosis. Keywords: babesiosis; canine; ehrlichiosis; IFAT; laboratory findings. ResumoO objetivo deste estudo foi determinar a prevalência de anticorpos IgG anti-Ehrlichia canis e antiBabesia vogeli em cães e correlacionar com a prevalência e fatores de risco para avaliar a relação do estado sorológico com os achados hematológicos. Amostras de sangue de cães coletadas de setembro de 2011 a março de 2012, no Hospital Veterinário da Universidade Federal de Lavras, Brasil, foram analisadas usando o teste de reação de imunofluorescência indireta (RIFI). Do total de amostras de soro de 160 cães, 23,7% (38 cães; IC95 17,7% -30,7%) foram soropositivos para E. canis, 40,0% (64 cães; IC95 40,0% -59,2%) para B. vogeli, e 5,6% (9 cães) para os dois hemoparasitas. Nenhuma das variáveis epidemiológicas mostrou associação significativa (P> 0,05) com a soropositividade para E. canis e B. vogeli. Cães soropositivos para E. canis mostraram valores médios mais baixos para hematócrito (P<0,05). No entanto, para o eritrograma, a contagem de plaquetas, o leucograma e os sinais clínicos, nenhuma diferença significativa (P> 0,05) foi observada entre cães soropositivos e soronegativos para E. canis ou para B. vogeli.

“…Canine babesiosis is a tick-borne disease of domestic and wild canids characterized by fever, depression, and anaemia (KUTTLER, 1988). Previous parasitological and serological studies carried out in Brazil have shown that canine babesiosis due to Babesia canis is distributed among different states with rates of seropositivity ranging from 1.9 to 66.9% in Minas Gerais (RIBEIRO et al, 1990;RODRIGUES et al, 2002;BASTOS et al, 2004;SOARES et al, 2006), 35.7% in Paraná (TRAPP et al, 2006, 5.2% in Rio de Janeiro (O'DWYER et al, 2001), and 10.3% in São Paulo (DELL'PORTO et al, 1993). In addition, the disease was also reported in the state of Mato Grosso, where it was molecularly confirmed as B. canis vogeli (SPOLIDORIO et al, 2011).…”

Canine ehrlichiosis and babesiosis are the most prevalent tick-borne diseases in Brazilian dogs. Few studies have focused attention in surveying tick-borne diseases in the Brazilian Amazon region. A total of 129 blood samples were collected from dogs living in the Brazilian eastern Amazon. Seventy-two samples from dogs from rural areas of 19 municipalities and 57 samples from urban stray dogs from Santarém municipality were collected. Serum samples were submitted to Indirect Immunofluorescence Assay (IFA) with antigens of Babesia canis vogeli, Ehrlichia canis, and six Rickettsia species. The frequency of dogs containing anti-B. canis vogeli, anti-E. canis, and anti-Rickettsia spp. antibodies was 42.6%, 16.2%, and 31.7%, respectively. Anti-B. canis vogeli antibodies were detected in 59.6% of the urban dogs, and in 29.1% of the rural dogs (P < 0.05). For E. canis, seroprevalence was similar among urban (15.7%) and rural (16.6%) dogs. For Rickettsia spp., rural dogs presented significantly higher (P < 0.05) prevalence (40.3%) than urban animals (21.1%). This first study on tick-borne pathogens in dogs from the Brazilian eastern Amazon indicates that dogs are exposed to several agents, such as Babesia organisms, mostly in the urban area; Spotted Fever group Rickettsia organisms, mostly in the rural area; and Ehrlichia organisms, in dogs from both areas studied.Keywords: Ehrlichia, Babesia, Rickettsia, dogs, Amazon, Pará state. ResumoEhrliquiose canina e babesiose canina são as doenças parasitárias transmitidas por carrapatos de maior prevalência em cães do Brasil. Poucos estudos pesquisaram doenças transmitidas por carrapatos na região da Amazônia brasileira. Um total de 129 amostras de sangue foram colhidas de cães da Amazônia oriental brasileira. Setenta e dois cães eram de áreas rurais de 19 municípios do Estado do Pará, e 57 amostras foram colhidas de cães errantes vadios da área urbana do município de Santarém-PA. As amostras de soro foram submetidas ao ensaio de imunofluorescência indireta, com antígenos de Babesia canis vogeli, Ehrlichia canis, e seis espécies de Rickettsia. A frequência de cães com anticorpos anti-B. canis vogeli, anti-E. canis, e anti-Rickettsia spp. foi de 42,6%, 16,2% e 31,7%, respectivamente. Anticorpos anti-B. canis vogeli foram detectados em 59,6% dos cães urbanos, e em 29,1% dos cães rurais (P < 0.05). Para E. canis, a soroprevalência foi parecida entre os cães urbanos (15,7%) e rurais (16,6%). Para Rickettsia spp., cães rurais apresentaram prevalência (P < 0.05) significativamente maior (40,3%) do que os cães urbanos (21,1%). Esse primeiro estudo sobre agentes transmitidos por carrapatos entre cães da Amazônia oriental brasileira indica que estes animais estão expostos a vários agentes. Estes incluem Babesia principalmente na área urbana, Riquétsias do grupo da Febre Maculosa principalmente nas áreas rurais, e Erliquia em cães de ambas as áreas, rural e urbana.

“…In Brazil, babesiosis disease is of great veterinary importance, being endemic throughout the country, and has been increasingly reported in different places (Bastos et al, 2004). Molecular studies have characterized B. vogeli (Passos et al, 2005;Sá et al, 2006), B. gibsoni (Trapp et al, 2006), and R. vitalii as the agents responsible for canine piroplasmosis in Brazil (Silva et al, 2011;Soares et al, 2011;Lemos et al, 2012).…”
