A Case of Maternal Sepsis and Fetal Demise Associated with Streptococcus pseudoporcinus

Abstract

Streptococcus pseudoporcinus has recently been described in relation to its colonization of the female genitourinary tract. Since prior reports have linked S. pseudoporcinus only with minor morbidities, the organism previously has not been considered to be a cause of serious puerperal infections. A 41-year-old gravida 2, para 1-0-0-1 presented with abdominal pain and intrauterine fetal demise. A beta hemolytic Streptococcus was isolated from her placenta, endometrium, urine, and two blood culture sets. The isolate was a Streptococcus pseudoporcinus, which colonizes the female genital tract and can resemble Streptococcus agalactiae. This case demonstrates that S. pseudoporcinus is a potential cause of severe maternal and fetal morbidity and mortality.
