Sterile guarded swabs were used to sample the anterior vaginal and cervical area of 23 normal healthy sows during various stages of the reproductive cycle. At least one positive sample was obtained from each sow and at each stage of the reproductive cycle. Most positive samples (78.3 percent) were obtained on the day of farrowing and the least 3 weeks after mating (19.0 percent). A wide range of bacteria including aerobic and anaerobic species, were recovered from 142 isolates. Both the percentage of bacterial isolates as well as the type of culture (pure or mixed) were similar to those frequently reported in clinical cases of vulval discharge syndrome. The results indicate that sows usually develop infections of the reproductive tract at farrowing and mating but these infections do not normally persist.
