In the present research, a total of 27 Wound swab samples were collected for the isolation of Methicillin Resistant-Coagulase Negative Staphylococci. Out of these, 3.7% of the samples have been shown the presence of Methicillin Resistant-CoagulaseNegative Staphylococci (MR-CoNS). The preliminary coagulase activity has been identified by Coagulase slide and tube method. The HiCrome MeReSa agar medium has been used for the preliminary identification of Methicillin resistance.

The genomic DNA was isolated from Methicillin resistant Coagulase Negative Staphylococciand other species of Staphylococcithrough Modified DNA extraction method. The isolated DNA was amplified through the thermal cycler using suitable forwardand reverse oligonucleotide primers, for the amplification of 527bp of mecA gene. The amplified DNA product has been identified by agarose gel electrophoresis using suitable 100bp ladder marker.
