--- Canine ehrlichiosis is well known as a worldwide, very important and potentially fatal infectious disease of dogs and other members of the canidae family. It is caused by Ehrlichia canis and transmitted by the brown dog tick Rhipicephalus sanguineus. The aim of this work was to make a retrospective case-control study in order to evaluate the risk factors associated with the presence of canine ehrlichiosis in dogs from the Clínica de Animales Menores y Laboratorio de Patología Clínica de la FMV-UNMSM. For this purpose, cases (dogs with ehrlichiosis: n igual a 50) as well as controls (dogs without ehrlichiosis: n igual a 100) from clinic charts data among the years 2002-2005 were used. The data recollected was grouped by breed, sex, age, ticks history and place. Chi square, odds ratio (OR), and logistic regression were performed. Fifteen different breeds were seen. From the cases, a 50% large breeds, 72% males, 64% older than 2 years, and 82% ticks were found. The risk factors associated with the disease were large breeds (OR igual a 12.8, p igual 0.024), German shepherd dog (OR igual a 12.2, p menor a 0.01), age (menor a 2-4 years: OR igual a 4, p igual a 0.008) and ticks history (82% (48/50) for the cases and 1% (1/100) for the controls). Key Words: E.canis, tick, case-control, risk factors, odds ratio.
