We report a rare case of urinary tract infection caused by uncommon gram positive entity Kocuria species, which are gram positive cocci often considered to be contaminant. In present case a 65 years male patient a known case of diabetes mellitus for past 30 years was admitted with complain of fever, generalized lower abdomen pain, discomfort and pain during micturition along with increased frequency and discomfort. Renal function test showed alteration. Urine sample was sent for routine microscopy and culture sensitivity for 3consecutive days. On each occasion tetrads and irregular clusters were seen on culture smear, initially we considered it as contaminant, since similar growth pattern and microscopic findings was seen on repeated isolation. We considered them significant by co-relating to patient’s clinical condition. Conventional methods showed coagulase negative (both slide and tube coagulase), mannitol was not fermented; however Kocuria species was identified with help of Vitek-2 compact. Antibiotic susceptibility testing showed sensitivity to vancomycin, Linezolid, Amikacin, Erythromycin, Teicoplanin. Most of the clinical microbiology laboratories ignore such bacteria as laboratory or specimen contamination, with increase reports of infection with this bacteria, it has now become important for clinical Microbiologists to identify them as potential pathogens and enumerate the antibiotic susceptibility pattern of these bacteria which will be helpful to clinicians for management of such patients.
