Urinary Tract Infection Caused by the Novel Pathogen, Lactococcus Garvieae: A Case Report

Ezza Fatima Tariq et al. Cureus. .

Abstract

Lactococcus garvieae is a part of the genus Lactococcus which was previously a part of the genus Streptococcus. It has been associated with serious diseases in aquaculture. However, human infections are rare. The most common presentation in humans is infective endocarditis. Urinary tract infection (UTI) is a unique presentation of this pathogen. We report the case of a 70-year-old male with a past history of benign prostatic hyperplasia who presented with confusion. Urinalysis confirmed the growth of L. garvieae. A seven-day treatment course of amoxicillin-clavulanate successfully treated the patient. The risk factors for acquiring the L. garvieae infections include contact with seafood or aquaculture. Other risk factors include immunosuppression, gastric acid suppression, and anatomical or physiological defect in the gastrointestinal tract. Special tests, such as VITEK® 2, API® 32 strep system, 16S rRNA, or polymerase chain reaction (PCR) testing, are needed for its diagnosis. Hence, we suggest underreporting of the infection may be possible. It is a novel cause of UTI, we suggest a high index of suspicion should be kept, especially in people with associated risk factors or exposure to seafood.

Keywords: amoxicillin – clavulanate; aquaculture; lactococcus garvieae (l. garvieae); urinary tract infection (uti).
