Post-partum, post-sterilization tubo-ovarian abscess caused by <it>Fusobacterium necrophorum</it>: a case report

<p>Abstract</p> <p>Introduction</p> <p>Post-partum, post-sterilization tubo-ovarian abscess is a rare event. <it>Fusobacterium necrophorum</it> subspecies <it>funduliforme</it>, a normal flora found mainly in the oral cavity, appears to be the etiologic organism.</p> <p>Case presentation</p> <p>In this case report, a 25-year-old Thai woman had a post-partum, post-sterilization tubo-ovarian abscess caused by the strictly anaerobic bacterium, <it>Fusobacterium necrophorum</it> subspecies <it>funduliforme</it>. Progressively severe symptoms started 3 weeks after her third vaginal delivery with a tubal sterilization on the following day. On admission, she presented with peritonitis and impending shock. An exploratory laparotomy showed a ruptured left tubo-ovarian abscess. A segment of her ileum had to be resected because of severe inflammation.</p> <p>Conclusions</p> <p><it>Fusobacterium necrophorum</it> subspecies <it>funduliforme</it> can be an etiologic organism of a ruptured tubo-ovarian abscess following tubal sterilization in a healthy host.</p
