Annals of Clinical Microbiology and Antimicrobials 2011 10 31 http content 10 1 31 ANNALS OF CLINICAL MICROBIOLOGY AND ANTIMICROBIALS CASE REPORT Open Access Central venous catheter-related bacteremia caused by Kocuria kristinae Case report and review of the literature Ryan Dunn1 Sara Bares2 and Michael Z David3 Abstract Kocuria species are unusual human pathogens isolated most commonly from immunocompromised hosts such as transplant recipients and cancer patients undergoing chemotherapy or from patients with chronic medical conditions. A case of catheter-related bacteremia with pulmonary septic emboli in a pregnant adult female without chronic medical conditions is described. A review of other reported Kocuria infections is provided. Introduction Kocuria species are ubiquitous in the environment and part of normal skin and oral flora of humans and other mammals 1 . They are however uncommon human pathogens with only a limited number of cases reported in the literature. K. kristinae is a facultative anaerobic bacterium that is a non-motile catalase-positive coagulase-negative gram- positive coccus that occurs in tetrads. It has been previously reported to cause bacteremia in chronically ill patients with malignancies or other immunosuppressed states 2-4 . K. kristinae has been associated with one case of cholecystitis 5 . Recently it has been associated with two cases of peritonitis related to peritoneal dialysis 6 7 . To the best of our knowledge we present here the first reported case of K. kristinae bacteremia in a pregnant but otherwise healthy adult female. Case Presentation In August 2010 a 29-year-old African American female who was 16 weeks pregnant presented to her primary care physician complaining of a fever of 103 degrees Fahrenheit chills pleuritic chest pain shortness of breath and a non-productive cough for 2 days. Her pregnancy had been complicated by thyrotoxicosis and hyperemesis gravidarum requiring the .
