  ABSTRACT: Phenotypic tests have limited discrimatory power to identify closely related members of genus Staphylococcus and particularly for identification of S. aureus. 157 isolates of S. aureus obtained from different clinical specimens were included in our study. To present a demonstration of our method’s sensitivity and ability to correctly detect S. aureus from uncultured clinical specimen, 30 known S. aureus positive but leftover uncultured clinical specimens from clinical microbiology laboratory were processed by our protocol and analyzed. All the 30 clinical specimens were confirmed as S. aureus among which 26 specimen were identified as MRSA and the remaining 4 as MSSA. These 30 clinical specimens used in the study showed 100% correlation with coagulase test and Cefoxitin disc diffusion method. Though commercial molecular diagnostic kits are available for detecting MRSA from swabs, this is probably the first time that multiplex PCR is being demonstrated directly on a variety of uncultured clinical specimens.
