CoNS which were considered as contaminants with minimal significance, have emerged as important agents of human disease. The recognition of increasing antimicrobial resistance among CoNS isolates constitutes a potentially worrisome emerging characteristic. Hence, this study was done to speciate and determine the resistant pattern of CoNS.
122 clinically significant CoNS isolates were obtained from various clinical samples between August 2016 to July 2017. These samples were processed conventionally.
Of the 122 CoNS species isolated majority were from pus. Identification of CoNS showed S.epidermidis 70 (57.4%), as the most frequently isolated species. Antimicrobial susceptibility pattern of the isolates showed maximum resistance to Penicillin. Methicillin resistance was seen among 19 (15.6%) isolates. But all the isolates showed 100% sensitivity to glycopeptides and Linezolid.
Meticulous identification, speciation and resistant pattern of the isolate is of paramount importance in clinical management of patients.
