Back ground -Group A Streptococcus (GAS) is one of the most common cause of pharyngitis. It may lead to rheumatic heart disease as complication. Prevalence of GAS pharyngitis in India is 4.2-13.7%. A study was conducted to find out prevalence of Group A Streptococcus causing sore throat in patient attending a tertiary care hospital of Western Odisha. Materials & method- Throat swabs of 350 patients presenting with sore throat were collected aseptically and culture was done as per standard protocol. Streptococcus pyogenes was identified with the help of colony morphology, bacitracin disc (0.04U) and group A specific antisera. Blood sample was collected from all culture positive patients and was tested for ASO test. GAS pharyngitis was considered only when patient was positive in both culture and ASO test. Antibiotic sensitivity test was performed as per CLSI guideline. Result-Prevalence of Group A Streptococcus in sore throat patients was 6%. Most of the positive cases were found in rainy season and in young (<30 yrs) patients of female sex. Penicillin and Amoxy clav showed 100% sensitivity against GAS and Erythromycin was 86% sensitive. Levofloxacin showed high resistance rate (43%). Conclusion- Prevalence of GAS in Western Odisha was lower than most of the studies in India. Penicillin and Amoxycillin were still 100% sensitive against GAS.
