Abstract
BackgroundKocuria, previously classified into the genus of Micrococcus, is commonly found on human skin. Two species, K. rosea and K. kristinae, are etiologically associated with catheter-related bacteremia.Case presentationWe describe the first case of K. kristinae infection associated with acute cholecystitis. The microorganism was isolated from the bile of a 56-year old Chinese man who underwent laparoscopic cholecystectomy. He developed post-operative fever that resolved readily after levofloxacin treatment.ConclusionOur report of K. kristinae infection associated with acute cholecystitis expands the clinical spectrum of infections caused by this group of bacteria. With increasing number of recent reports describing the association between Kocuria spp. and infectious diseases, the significance of their isolation from clinical specimens cannot be underestimated. A complete picture of infections related to Kocuria spp. will have to await the documentation of more clinical cases.

ConclusionOur report of K. kristinae infection associated with acute cholecystitis expands the clinical spectrum of infections caused by this group of bacteria
Kocuria, previously classified into the genus of Micrococcus, is commonly found on human skin
Kocuria is previously classified as Micrococcus and, being inhabitants of the skin, it is not surprising that K. rosea and K. kristinae have been incriminated as pathogens causing catheter-related bacteremia [2,4]
Summary
Previously regarded as an innocuous microorganism, there have been a number of recent reports describing the association between Kocuria spp. and infectious diseases. The complete clinical spectrum of infections caused by this group of bacteria will be more apparent after the report of more cases. The physician should not underestimate the importance of K. kristinae when isolated from clinical specimens
