Enhancement of Herpesvirus Type 2 Infection in Pregnant Mice

Abstract
Pregnant and nonpregnant mice were infected with HSV-2 by the intravaginal, i.p., i.v. and intranasal routes. An enhancement of infection in pregnant mice was demonstrated only by the intravaginal route. Infection with a respiratory virus (influenza A) demonstrated that pregnant mice were not more susceptible and were perhaps more resistant than nonpregnant mice to this infection.
