A Rare Surgical Site Infection Caused by Leifsonia aquatica (Non-diphtheric Corynebacterium) in an Immunocompetent Patient: A Case Report From North India

Here we present a case report on a <i>Leifsonia aquatica</i> (<i>L. aquatica, </i>non-diphtheria <i>Corynebacterium</i>) infection in an apparently immunocompetent patient. The organism was isolated from the collection of a lesion in the thigh that presented 15 days post surgery of a fractured femur. The patient had undergone a surgical procedure for a fractured femur with an external device placed, after which she developed pus discharge from the surgical site. This discharge was not associated with any other symptoms such as fever, malaise, chills, or rigor. Pus was processed conventionally for culture, and sensitivity and identification of organisms were done on an automated system. The organism isolated from the sample was identified as <i>L. aquatica,</i> which is a non-diphtheria coryneform bacteria that is considered a rare cause of infection. It was susceptible to vancomycin, linezolid, teicoplanin, and quinolones. The present case report describes the rare case of <i>L. aquatica</i> from surgical site infection.
