The main objective of this work was to determine the prevalence and correlation between urinary tract infections and the presence of Actinomyces suis in the urine of 1,745 pregnant sows in southern Brazil. Urinary infections were present in 29.54 % of the sows raised in confinement and in 16.46% of the sows raised outdoors. The overall prevalence of urinary infections was 28.31%. For the presence of A. suis, 22.24% of the sows raised in confinement and 6.71% of the sows raised outdoors had the bacteria in their urine. The prevalence of A. suis in all sows was 20.63%. Negative correlation was demonstrated between the presence of urinary infections and the presence of A. suis. In other words, sows which had urinary infections had lesser prevalence of A. suis (13.67%) than those sows without urinary infections (23.12%). In the same way, sows positive for A. suis had lesser prevalence of urinary infections (17.43%) than those negative for the bacteria (28.62%). Only 3.60% of the sows had urinary infection and A. suis in the urine simultaneously.
