Resumo: | ABSTRACT: This study aimed to characterize the outbreaks of equine infectious anemia (EIA) identified, between the years 2009 and 2015, in the western region of the state of Rio Grande do Sul, Brazil. We identified 26 positive horses on 24 properties. Each positive property was considered an outbreak of the disease. The diagnoses were made using the agar gel immunodiffusion (AGID) test as a part of the sanitary checks conducted during animal transportation or certification of the horse´s sanitary status. The positive properties included farms or horse barns, and the infected animals were used for ranch work, sports, or reproduction. One outbreak was identified in animals that were being illegally transported from Argentina to Brazil. Fifteen outbreaks occurred on properties that were not registered with the Official Veterinary Service (OVS). Eleven outbreaks were identified in urban areas and 13 in rural areas. Twelve of the 24 outbreaks were diagnosed in 2015 alone, nine of which occurred in São Borja county. On two properties, a diagnosis could not be confirmed with a retest; therefore, these outbreaks were discharged. During sanitation checks on three properties, 12 additional positive animals were identified among a population of 1,108 susceptible animals. Based on these findings, we concluded that a subclinical form of the infection is present in that area, which is linked to properties that are not registered with the OVS, and that animals which are transported illegally across international borders represent a potential risk.
