Methicillin-Resistant Staphylococcus aureus (MRSA) is responsible for an increasing number of serious hospital and community acquired infections. Methicillin resistance has become an important problem in the community. Thus it is very essential to study the clinical correlation to know the significance. This study reports the prevalence of MRSA isolated at a tertiary care centre, Hyderabad and the clinical correlation. A total of 110 consecutive S. aureus isolates were obtained from clinical samples during the study period of Jan 2013-May 2014. All the strains were tested phenotypically by conventional methods and genotypically by Uniplex-PCR targeting S. aureus nuc gene, Panton-valentine leucocidin (PVL) toxin gene and mec A reisistance genes. Of these 82 (74.5%) of the total number of the isolates were recovered from pus/ exudates (skin and wound infections) followed by blood 21 (19%) and sputum (lower respiratory tract infection) 7 (6.3%). 53(48%) isolates of MRSA caused infections. All the 110 strains previously identified phenotypically as S.aureus with bacteriological examination were positive for amplification of 460 base pair fragments specific for nuc gene of S.aureus. Moreover, 48% of S. aureus were positive for amplification of 300 base pair fragments specific for mec A gene, while only 47% of MRSA were positive for amplification of 976 base pair fragments specific for PVL gene. Methicillin resistance was 48 %
