Background: Sore throat and pharyngitis are one of the most common of the physical complaints, which result in a clinical visit for diagnosis and treatment. Group A Streptococci (GAS) is the most common cause of bacterial pharyngo-tonsillitis. MATERIALS AND METHODS: The present study was conducted during a one year period from January to December 2012. A total of 158 throat swab samples were processed during the study period using standard techniques. The throat swabs were inoculated on to sheep Blood Agar & MacConkey agar, and incubated over night at 370C. Any growth was smeared for Gram’s stain, and the organisms were further processed, and antibiotic sensitivity done using Microscan autoSCAN-4 instrument (SIEMENS). RESULTS & CONCLUSIONS: A total of 158 throat swabs were processed during the study period (January to December 2012). Out of 158 samples, 67 samples (42.4%) were positive for growth of pathogens and 91 (57.59%) were negative. Staphylococcus aureus was the predominant isolate (34.32%), followed by Streptococcus pyogenes- 25.37% and Klebsiella pneumoniae- 23.88%. Group A Streptococcal pharyngitis has to be identified properly and treated promptly to avoid un-necessary complications further.
