Reviewing the Emergence ofLactococcus garvieae: A Case of Catheter Associated Urinary Tract Infection Caused byLactococcus garvieaeandEscherichia coliCoinfection

Abstract

Lactococcus garvieaeis considered a low virulence organism which is rarely associated with human infections. Most of the reported cases have been associated with bacteremia with or without endocarditis. We report a rare case of catheter associated urinary tract infection (CAUTI) caused byLactococcus garvieaeandEscherichia colicoinfection without any bacteremia in a patient with indwelling urinary catheter placed for benign prostatic hyperplasia (BPH). The patient also had a history of gastroesophageal reflux disease (GERD) with long standing famotidine treatment. In our case,Lactococcus garvieaewas initially misidentified asEnterococcusspecies but was later detected by automated microbial identification system VITEK-2 (BioMerieux, Marcy-l'Étoile, France) and was confirmed with API 32 Strep system (BioMerieux, Marcy-l'Étoile, France). The patient responded well to a two-week course of cephalosporin. Interestingly, apart from the acid suppressive treatment, no other risk factors were identified.
