Epidemiological data collection The dog owners who participated in the study completed an epidemiological questionnaire, from which was acquired information about factors that could act as risk factors for infection, such as the presence of ticks, contact with other dogs, habitat, age, and gender. BMJ ; Blood samples were collected from dogs and submitted for indirect immunofluorescent assay and polymerase chain reaction testing for the detection of Ehrlichia spp.

This finding may be explained by the fact that diagnosis by IFA is more effective in the advanced stages of the disease, with reduced sensitivity in the initial phase of infection leading to false negatives. Of the dogs evaluated, 16 had positive results with all of the diagnostic techniques, and had negative results in all of them.

The negative and positive controls used for the dogs were canine sera on which serology had been performed in a prior study CARLOS et al.

Molecular detection of tick-borne bacterial agents in Brazilian and exotic captive carnivores. The absence erichiose E. The increasing interest of researchers in conducting studies about elrichiose disease is due to the high morbidity and mortality of canine ehrlichiosis in Brazil. Serologic prevalence of Dirofilaria immintis, Ehrlichia canis and Borrelia burgdorferi infection in Brazil.

To analyze the risk factors, all animals exposed erlichioze agent were considered seropositives on IFA or positives on blood-smear examination or nested-PCR testing. J Vet Diagn Investv. Molecular studies indicate that new strains of Ehrlichia spp. Rev Bras Parasitol Vet ; 18 4: Ehrlichia canisE.

Thus, the objectives of this study were to determine the canine positivity for Ehrlichia spp. Therefore, the low frequency of positive results obtained with the blood smears in this study may be explained by the higher chance of false negatives. Younger dogs and rural habitat were protective factors and presence of ticks and contact with other dogs were the risk factors associated with exposure to the agent. On IFA, the seroprevalence The dogs positive in one of the three techniques were considered exposed Furthermore, this study identified factors associated with exposure to the agent in dogs in this locality.

Prevalence of Ehrlichia canis Rickettsiales: In addition to the above mentioned points, because serological testing identifies only antibodies, a positive case cabina serology may appear negative on PCR testing because of eradication of the Ehrlichia organisms by the immune system. Ehrlichia canis J Clin Microbiol ; 36 1: This may also explain the absence of detection of E.
