Vertical transmission of Salmonella enterica serotype Paratyphi A leading to abortion

Abstract

Introduction. Enteric fever, caused by Salmonella enterica serotype Typhi (typhoid fever) or S. enterica serotype Paratyphi A, B or C (paratyphoid fever), is a major health problem in developing countries. Vertical transmission of Salmonella can cause miscarriage, still birth, preterm labour and neonatal sepsis. In the literature, many cases of vertical transmission of S. enterica Typhi from mother to foetus have been reported, but there are very limited studies showing vertical transmission of S. enterica Paratyphi. Case presentation. Here, we report a rare case of S. enterica serotype Paratyphi A infection in a pregnant woman resulting in a spontaneous miscarriage. S. enterica serotype Paratyphi A was isolated from placental membrane in culture. Conclusion. A high index of suspicion, along with timely cultures of relevant samples, like blood and stool, and timely initiation of antibiotic therapy in pregnancy could possibly save the lives of such foetuses.
