Hormonal changes and its inhibitory effect on the immune system in pregnant women may predispose them to various infections, including typhoid fever caused by Salmonella enterica. Gastroenteritis and septicemia caused by this bacterium can infect the placenta and fetus if they occur during pregnancy, and if not treated early, they may be associated with risks such as abortion. This report is about a pregnant woman with an infectious abortion who referred to Sarem Hospital in Tehran. Patient Information In this report, a case of abortion caused by Salmonella enterica serotype Typhi was reported in a 35-year-old pregnant woman who was admitted to a hospital in Iraq with symptoms of gastroenteritis about a month before abortion and was discharged without antibiotics. Widal serological test and blood culture of the patient were negative and the bacterium was isolated from placenta in culture. Conclusion Gastroenteritis and gastrointestinal symptoms such as diarrhea and vomiting in pregnant women, especially in the first trimester of pregnancy, should be monitored for salmonella infections, because there is a risk of infection and abortion due to infection. Serologic tests such as Widal test or a blood culture are not enough for this purpose, as false negative results are likely to occur in such cases.
