Introduction: Most Corynebacteria and other gram positive rods have been classically considered contaminants of microbiological samples, however, advances in microbial identification offer a new insight on their pathological significance. In this report, we present a first case of clinically significant bacteremia of urinary origin caused by Corynebacterium aurimucosum and a brief review of the literature.
Case Report: Corynebacterium aurimucosum was isolated in both urinary and blood samples of a 94-year old patient with fever and bacteremia. The isolated pathogenic organism was identified in the samples using mass spectometry (MALDI-TOF), and was treated with amoxicillin/clavulanic with clinical improvement and stability at three weeks follow up. This was the first reported case of clinically significant bacteremia caused by this isolate, although infections at different sites have reported.
Conclusion: New techniques of microbial identification show gaining importance of Corynebacterium spp. in clinically-relevant infections, thus modifying progressively the established spectrum of disease caused by GPRs. Detailed reporting of new cases could contribute to a better understanding of the burden of the disease.
Keywords: Aurimucosum, Bacteremia, Corynebacterium, Gram-positive rods
