Abstract :

Introduction: CoNS are recognized as important pathogen for nosocomial infections. We aimed to analyze the emergence of CoNS isolates and its antimicrobial resistance. Materials and methods: study from Jan – April 2017.A total of 5220 samples were studied. All samples were subjected to direct microscopy and culture. Culture positive samples were processed by doing Gram staining and Coagulase test. CoNS isolates were subjected for antibiotic susceptibility testing. Result: Out of the 5220 samples cultured, 2210 samples showed significant bacterial growth among these 684 samples showed the growth of Gram positive isolates. Out of the 684 isolates 141(20.61%) were CoNS. The isolates showed 100% sensitivity to vancomycin and linezolid. But 55% CoNS were MR CoNS. Most of the isolates were showing high degree of resistance towards the commonly using antibiotics like ampicillin (87%), penicillin (65%) and erythromycin (65%).While least resistant was showed against clindamycin, gentamicin and amikacin. Conclusion. The emergence of antibiotic resistance against CoNS is a matter of serious concern. If this acquires resistance to major antibiotics it is going to become a threat to the clinical settings.
