Abstract
Background and Objectives: Increased frequencies of CoNS infection is being observed in various hospital setups and a need for better understanding of species distribution and antimicrobial susceptibility pattern prevailing among them has arisen. The rising incidence of bacteraemia along with the long term use of indwelling prosthetic devices is of great concern and demands further research. The study is done to speciate the Coagulase negative Staphylococci isolated from various clinical samples and to reveal the antimicrobial susceptibility pattern among them.
Method: The present study was conducted in the Department Of Microbiology and Department of Medical Laboratory Technology, Government Medical College Thiruvananthapuram. A total of 52 strains of Coagulase negative Staphylococci isolated as a sole agent from various clinical samples were included in the study. The speciation of CoNS was done based on the biochemical reactions.
Results & Conclusion: Out of 52 sample, 61.5% is male population and most of the samples were exudates and 27% of the patients were coming under the working age group. Staphylococcus epidermidis is recognized as the predominant species (58% of the total isolates). 19.2% were Methicillin resistant CoNS (MR-CoNS). 44.2% of all isolates shows induced Clindamycin resistance.
Keywords: CoNS, MR CoNS.
