Vectors represent an important role in the transmission of Salmonella in pigs by introducing these microorganisms on farms, constituting source of contamination or receptors in the existing infections on farms. In order to emphasize the role of vectors in the transmission of Salmonella in pigs, in the present study was started by collecting and analyzing samples of faeces from pigs, and vectors (rats / mice, birds, insects) nearby. Out of 100 collected faecal samples from pigs, a total of 40% (40/100) of samples were positive Salmonella spp. Analyzing the 50 samples of stool collected from mice and rats, it was found a total of 30% (15/50) positive samples, from birds of the 50 samples collected 26% (13/50) samples were positive, and of the 30 insects analyzed, 20% (6/30) samples were positive for Salmonella spp. The most common serovars isolated by means of API 20 E, such as pigs and vectors were S. Typhimurim, and S. Choleraesuis, S. Derby was isolated only in pigs. Based on these results we can say that the vectors constitute an important role in the spread of Salmonella in pig farms, but the role of rodents seems to be more relevant to other vectors in the study (birds, insects). Therefore to reduce the risk of contamination of pigs with Salmonella spp. are necessary for the application of control measures on farms.
