Vagococcus: An under-recognized and emerging cause of antibiotic-resistant infection

Abstract

Vagococcus, a bacterium generally isolated from fish and domestic animals, is a rarely reported human pathogen whose clinical characteristics and antimicrobial susceptibility remain uncertain. In this case report we describe a 19-year-old active-duty military sailor who suffered a blast injury to the left foot from a firework explosion. The injury was complicated by a polymicrobial wound infection that included Vagococcus fluvialis. Vagococcus spp. infections in humans are often associated with skin and soft tissue infection, including those resulting from trauma or blast injuries. This case serves to highlight this pathogen’s role in causing invasive infections and as well as the importance of recognizing its clinical characteristics and antibiotic resistance profiles.
