Isolation of Actinobacillus seminis from a goat with clinical epididymo-orchitis in Brazil

Abstract

The present study reports the first isolation of Actinobacillus seminis from a goat in Brazil. A fouryear- old Moxotó breeding goat in a flock of 70 goats and 65 sheep reared together in the county of Patos, semiarid region of Northeastern Brazil, showed clinical signs of unilateral orchitis and epididymitis. Diagnosis of A. seminis infection was confirmed by association of clinical findings, bacterial isolation and 16S rRNA gene sequencing. This result suggests that A. seminis may be an additional cause of infertility in goats, and that sheep may be the source of infection because the mixed farming system allows the contact between sheep and goats in the semiarid region of Northeastern Brazil. © 2014, Sociedade Brasileira de Microbiologia.
