Resumo
In successful artificial insemination (AI) programs, it is critical that AI studs produce high-quality
semen samples. Samples presenting bacterial contamination reduce in vitro sperm quality and also
act as vehicles for disease transmission. The objective of this study was to identify the presence of
bacteria contaminants in the vulvar secretion of inseminated sows and in semen and preputial secretion
of the boars used as semen donors and to relate such presence with clinical findings. Three crossbred
F1 boars and 15 sows from a commercial swine farm were evaluated. The microorganism isolated
from the vulva, prepuce and sperm were submitted to biochemical and stain characterization. One of
the evaluated boars presented clinical signs of genital infection. From the five sows inseminated with
semen from such boar, three returned to estrus after AI and two presented purulent vulvar discharge.
Escherichia coli and Staphylococcus aureus were the agents isolated from the samples. Simultaneous
contamination with both agents was observed in two boars and in 20% of the sows. The presence of E.
coli as a single contaminant was only observed in females (13%), whereas the presence S. aureus alone
was observed in both sexes. The presence of pathogens in the examined samples suggests that it might
be responsible for the low reproductive performance in the herd.
