Abstract

OBJECTIVE: Streptococcus porcinus has previously been isolated from the genitourinary tract of reproductive-aged women. However, very little is known about the pathogenicity of this microorganism in pregnancy. The study aimed to report pregnancies complicated by vaginorectal S. porcinus and associated adverse outcomes. MATERIALS AND METHODS: We present 2 patients with 3 pregnancies complicated by vaginorectal S. porcinus and preterm cervical change. RESULTS: The first patient lost a twin pregnancy to previable preterm rupture of membranes. During her subsequent pregnancy, again positive for S. porcinus, cervical shortening prompted antibiotic treatment and cerclage. The second patient delivered preterm despite cerclage placed for sonographic indications. CONCLUSIONS: Our cases suggest that S. porcinus may contribute to the pathogenesis of preterm rupture of membranes and cervical insufficiency.
