Vaginal microbiota as an unusual cause of spondylodiscitis

Abstract

The incidence of extra pelvic infections due to vaginal microflora bacteria has increased as growth media and methods of isolation have improved. However, bone infections seem to be still relatively rare, and little is known about their risk factors, clinical presentation, treatment and final outcome. We describe here a spondylodiscitis due to Gardnerella vaginalis, Atopobium vaginae, Peptostreptococcus indolicus and Prevotella amnii, anaerobic bacteria from vaginal microbiota. Our patient had no obvious predisposing factor and recovered after antibiotic treatment. To our knowledge, this case is the first reported spondylodiscitis caused by polymicrobial vaginal flora in a healthy, immunocompetent woman.
