Salmonellosis as risk factor for stillbirth in guinea pigs
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 CaseControl 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’ 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 noninfectious causes. The results show that Salmonella should be considered as a cause of stillbirths in guinea pigs.

Se evaluó la asociación entre casos positivos a aislamiento de Salmonella sp a partir de hisopados vaginales dentro de las 24 horas del parto y la mortinatalidad en una granja de cuyes en Huancayo, Perú. Se trabajó con 258 cuyes siguiendo un diseño de Caso-Control, pareando el tamaño de camada y utilizando como covariables al número de parto y el galpón de procedencia de la reproductora. En el grupo de ‘Caso’, se incluyeron hembras en cuyo parto hubo por lo menos un mortinato y en el ‘Control’ hembras con toda la camada viva. El 8.5% de las reproductoras en el grupo de ‘Caso’ resultaron positivas a Salmonella sp, y mediante el análisis de regresión logística se estimó una Odds Ratio de 4.32 (95% de intervalo de confianza, p<0.05) de los casos positivos respecto a los controles. Por otro lado, la causa de muerte en el 91.5% (118/129) de hembras con mortinatos se debería a otras causas infeccionas o a causas no infecciosas. Los resultados indican que la salmonelosis debe ser considerada como una de las causas de mortinatalidad en cuyes.
