ABSTRACT
This study aimed to diagnose Mycobacterium avium subsp. paratuberculosis (MAP) infections in sheep in the state of Pernambuco, Brazil. A total of 276 blood samples were analyzed using the enzyme-linked immunosorbent assay IDEXX Paratuberculosis Screening kit, and 261 fecal samples were submitted for bacterial culture and polymerase chain reaction tests. An animal-level sero-frequency of 0.72% (n = 2/276) and a farm-level sero-frequency of 20% (n = 2/10) were found. All fecal sample cultures were negative, and molecular analyses were also negative. To the best of our knowledge, this is the first study of MAP infection in sheep in the state of Pernambuco and one of the pioneers in the country. It is an asymptomatic disease that is difficult to diagnose in this species because the susceptibility of sheep to the organism is lower than that of other ruminant species. However, the sero-frequency found reveals that there is MAP exposure in sheep flocks in the region. In addition, serological monitoring can contribute to the observation of the organism's behavior in herds. Our results support the potential risk of MAP infection in sheep in the state of Pernambuco, Brazil.
