Streptococcus pyogenes is one of the commonest bacterial pathogen that causes pharyngitis especially among children. Aim: To isolate Streptococcus pyogenes from children attending paediatric and ENT OPD, AIMSR, Bathinda and to find their antimicrobial susceptibility pattern. Material & Method: 200 children, aged 5-15 years, clinically suspected of acute Streptococcal pharyngitis and tonsillitis were included in the present study. The study was conducted over a period of one year from January 2015 to December 2015. Throat swabs were collected from patients for gram stain and culture. Streptococcus pyogenes was identified by beta hemolytic colonies on blood agar and confirmed by Bacitracin sensitivity and PYR positivity. Results: Among 200 clinically suspected children, Streptococcus pyogenes was isolated from 26 cases, prevalence being 13%. The prevalence was more in the age group 5-10 years. All the isolates were sensitive to Penicillin, Amoxicillin, Cephalexin, Cefuroxime (100%), 95.83% of isolates were sensitive to Azithromycin while 70% were sensitive to Erythromycin. 30.76% of the culture positive cases were also positive for the Antistreptolysin ‘O’ antibodies.
