The association between positive cases of Salmonella sp isolated from vaginal swabs collected within 24 hours of the parturition and stillbirth in a guinea pig farm in Huancayo, Peru was evaluated. The study included 258 breeding females using a Case- Control design, where litter size was paired between the two groups and parity and number of birth and barn of the breeding female were used as co-variables. In the ‘Case’ group were included females with at least one stillbirth per litter and in the ‘Control’ Salmonelosis asociada a mortinatalidad en cuyes group were included females where the entire litter was alive. Results showed that 8.5% of the breeding females in the ‘Case’ group were positive to Salmonella sp, and by the logistic regression analysis was estimated an Odds Ratio of 4.32 (95% confidence interval; p<0.05) for positive cases in relation to the controls. On the other hand, the cause of death in 91.5% (118/129) of the females with stillbirths was due to other infectious or non- infectious causes. The results show that Salmonella should be considered as a cause of stillbirths in guinea pigs
