In Brazil, goat livestock has social and economic importance for rural populations, mainly in the Northeast region. The productive performance, however, is unsatisfactory, due to the low use of technologies, as well as the inefficient reproductive health management. This is can result in serious consequences in the productivity of the herds. Infections, especially bacterial infections, can cause subfertility or infertility. Normal microbiota species are important in maintaining health and in the possibility of causing disease. These are capable of becoming pathogenic in errant conditions or in situations of immunosuppression. In addition, the absence of normal bacterial flora in the prepuce may facilitate the establishment of opportunistic infections by pathogens of clinical importance. Some studies have described the bacterial microbiota present in the prepuce of animals, however, there are very few publications on the prepuce microbiota in goats. To detriment of the scarce data, the objective of this study was to describe, through isolation and identification, the bacteria that inhabit the prepuce of goat breeders in the Agreste Paraibano and Borborema regions of the state of Paraíba, Brazil. Samples from the preputial cavity of 40 goats were collected and analyzed microbiologically. The results showed bacterial growth in all prepositional Swabians, the 81 isolates found belong to 16 genera and 26 different species. The most prevalent bacteria were Bacillus spp. (28.4%), Citrobacter sp. (9.9%), Corynebacterium sp. (7.4%), Staphylococcus sp., Klebsiella sp. and Streptococcus spp. (4.9% each), S. lutrae and Tatumella spp. (3.7% each). The results differed from those found in the literature and showed a good diversity of bacteria from the prepuce microbiota of these goats. Although most of the isolated bacteria are considered commensal, several can be opportunistic pathogens under favorable conditions.
