Bovine genital campylobacteriosis (BGC) is an infectious disease caused by Campylobacter fetus, which determines temporary infertility, mild endometritis, miscarriage in females and also increases the calving interval. The occurrence of BGC in the Brazilian herds has varied widely among regions. The aim of this study was to identify by polymerase chain reaction (PCR) the occurrence of C. fetus in bovines from Rio Grande do Sul (RS), Brazil using samples collected from1999 to 2010. A total of 816 samples from 37 counties localized predominantly in the Southwest and Central Western regions of the RS state were analyzed. Four hundred eighty preputial aspirated samples (92 from artificial insemination centers and 388 from farms that use natural mating) and 324 cervical aspirates and abomasal contents of 12 aborted fetuses were analyzed. As result, 10.9% (89/816) were positive for C. fetus. When the results were analyzed in relation to its origin, 6.5% (6/92) of the males samples from insemination centers were positive, and the ones from natural mating 9% (35/388) were positives. For the females, this percentage was 13.6% (44/324) of positivity, and the samples from the aborted fetuses 33.3% (4/12) were positive. When the 91 farms that used natural mating and the 37 counties were analyzed, it showed a positivity rate of 44.0% (40/91) and 63.2% (24/37), respectively. This study shows the importance of BGC for bovine herds, and a larger occurrence of positive samples among females when compared to male.
