The study aimed to identify risk factors associated with Chlamydophila abortus infection in sheep and goats from the Litoral/Zona da Mata and Agreste region of Pernambuco state, Brazil. Serum samples (n=290) were analyzed to detect Chlamydophila spp. antibodies in 12 farms. Questionnaires were applied to identify risk factors. Frequency of serum-reactive animals were 10.3% (12.0% in ewes and 8.1% in goats) and 1/12 (91.6%) infection focuses were identified. This is the first report on anti-Chlamydophhila abortus antibodies in goats and sheep in Pernambuco and Brazil, respectively. Risk factors associated with goat infection were breed (OR=9.10) and management (OR=6.41). No significant associations in any of the analyzed factors were found for sheep. In summary, Chlamydophila sp. infection is disseminated in sheep and goat herds in the region. Control measures should be established, focusing primarily risk factor identified in this study, to reduce the possibility of infection by the agent.
