Coagulase negative Staphylococci (CoNS) were generally considered to be contaminants in the past having little clinical significance. Over the past two decades, these organisms have become recognized as important agents of human disease. S. epidermidis is the predominant agent in nosocomial infection, bacteremia, surgical wound and urinary tract infections. Characterization of CoNS isolated from urine samples, their antibiogram and methicillin resistance. The study was conducted from December 2014 to August 2015. We received 518 urine samples, 33 strains of CoNS were isolated. The organisms were identified and speciation was done by standard biochemical reactions. Antibiotic susceptibility testing was done by Kirby-Bauer disk diffusion method and following Clinical laboratory standards institute guidelines (2015). From urine culture, 33/518 (6%) were obtained as CoNS isolates. From CoNS isolates, majority was in the age group of 0- 14 years 25(76%). Maximum isolates were from females 20(60%) than males 13(40%). The most common species isolated was S. epidermidis 18(55%), followed by S. saprophyticus 14(42%) and S. lugdunensis 1(3%). Methicillin resistance was found 61% of strains. Linezolid (100%), Amikacin (79%), Doxycycline (76%), Nitrofurantoin (67%), Gentamicin (61%), Erythromycin and Norfloxacin (each 58%) and Ciprofloxacin (55%) were found to be the most effective antibiotics. S. epidermidis was the predominant species isolated and more susceptible antibiotics were Linezolid and Amikacin.
