Abstract

Ruminococcus gnavus is a Gram-positive anaerobe and normal gut commensal in the human host. There have been a small number of reported cases of infections attributed to R. gnavus, and no cases of urogenital infections have previously been published. We describe here a case of bilateral tubo-ovarian abscesses (TOAs) which cultured a pure growth of R. gnavus in a young female with concurrent deep infiltrating endometriosis and evidence of pelvic inflammatory disease. This case provides an insight into the behaviour of R. gnavus as a coloniser of the human host and provides further incentive to investigate its potentially pathogenic role in inflammatory conditions such as pelvic inflammatory disease.
