Background: Chlamydophilosis is a disease caused by the bacterium Chlamydophila abortus, responsible for reproductive damage in small ruminants, and economic losses to animal production. In addition, it is classified as a zoonosis once it presents symptoms similar to numerous bacterial and viral infections of the reproductive system, making clinical diagnosis difficult. The objective of this work was to estimate the seroprevalence of anti-C. abortus antibodies in goats and to identify the risk factors for the disease in two mesoregions of Rio Grande do Norte, Brazil.Material, Methods & Results: This research was carried out in two mesoregions of the State of Rio Grande do Norte (Central Potiguar - CP and West Potiguar - WP) located in the Northeast of Brazil. These mesoregions together represent 83% of the regional herd. A total of 54 properties were studied. Those are distributed in seven municipalities: Afonso Bezerra, Angicos, Lages and Pedro Avelino, in the CP mesoregion; and Apodi, Caraúbas, and Mossoró, in the OP mesoregion. We used 540 animals from herds characterized as non-defined breed (NDB) and native breed, regardless of their productive functions, being frequent the consortium of caprine and ovine species. Blood samples were collected through jugular venipuncture by vacuum system with 5 mL tubes without anticoagulant. After collection, the tubes were centrifuged at 1500 g for 15 min. Detection of anti-Chlamydophila sp. antibodies was performed by the Complement Fixation Test. In parallel with the collection, a questionnaire was applied addressing general property and producer characteristics. Seroprevalence of chlamydophilosis in the CP mesoregion was 3.04% (7/230) for the animals and 26.1% (6/23) for the properties, whereas, in the WP mesoregion, the values were 4.2% (13/310) and 35.5% (11/31), respectively.[...](AU)
