Case reports also document the use of ampicillin for Salmonella infections. In one instance, a pregnant woman came down with gastroenteritis one week before delivery. The newborn infant was subsequently treated with Principen, gentamicin (an antibiotic), and amoxicillin
(an antibiotic); however, five months later, Salmonella was still present. In this case, researchers discussed the potential route of infection and the guidelines for treatment and management of this type of bacterial infection in pregnancy and post-partum.
