title: [Factors associated with Ehrlichia canis infection in dogs infested with ticks from Huanuco, Peru].
abstract: The aim of the study was to determine the frequency and associated factors of Ehrlichia canis infection in dogs. Blood samples from 150 dogs infested with ticks in 10 veterinary clinics in the city of Huanuco in Peru were collected. The dogs were randomly selected without regard to breed, age or sex. Ehrlichia canis antibodies were detected by chromatographic immunoassay.51.3% of dogs were infected with Ehrlichia canis. In the multivariate analysis, factors associated with the presence of Ehrlichia canis were: poor health of the dog (p = 0.049), a higher average of tick infestation (p = 0.018), and adult dogs (p = 0.038). The frequency of Ehrlichia canis in dogs of this city is high. Control of the brown dog tick (Rhipicephalus sanguineus) vector of Ehrlichia canis is recommended.
