Animal Models of Ascending Genital‐Tract Infection in Pregnancy [PDF]

open access: yesInfectious Diseases in Obstetrics and Gynecology, 1994
This article reviews animal models currently used for investigation of ascending genital‐tract infection in pregnancy. The specific models reviewed are those in the rabbit, monkey, and mouse. These models investigate both the direct effects of bacteria in the setting of ascending infection and the role of cytokines produced by the immune system.
