Abstract
Introduction: Βeta haemolytic streptococcal infections have a worldwide distribution among children and it poses an important health problem globally. So, a five months study was conducted to know the prevalence of beta haemolytic streptococci (BHS) in the throat of school children. Materials and Methods: Throat swabs from 200 school children of Kirtipur were collected, transported to the laboratory and were processed for BHS following standard microbiological procedures. Group A Streptococci (GAS) were identified by beta haemolytic colonies, bacitracin sensitivity and catalase negativity test. ASO test was also performed from serum samples. Result: Altogether 18 (9%) BHS isolates were identified from 200 samples, out of which 11 (5.5%) isolates were from males and 7 (3.5%) were from females. Among the 18 BHS isolates, 10 were identified as GAS isolates. The number of GAS presented only 5% of total sample. There was no significant sex difference in colonization of GAS (p> 0.05). Majority of cases were asymptomatic. All GABHS isolates were sensitive to Penicillin. In Serological examination, i.e. Antistreptolysin O (ASO) titre, all serum samples showed less than 200 IU ASO titre. Conclusion: This result highlights the current situation of GABHS throat infection in school children of Kirtipur.

Highlights
Beta haemolytic streptococci (BHS) have been recognized as pathogens causing a wide variety of disease states
Throat swabs of 200 school children within age limit of 3-6 years were collected for the purpose of the study
The sample was transported to the laboratory of Kathmandu Clinic within 2 hours of sample collection for processing as standard microbiological procedures[6, 7, 8]
Summary
Beta haemolytic streptococci (BHS) have been recognized as pathogens causing a wide variety of disease states. Group A Streptococcus (GAS) consists of a single species, Streptococcus pyogenes[1] It belongs to Lancefield group A and is beta-hemolytic, called Group A beta-hemolytic Streptococci (GABHS)[2]. A five months study was conducted to know the prevalence of beta haemolytic streptococci (BHS) in the throat of school children. Group A Streptococci (GAS) were identified by beta haemolytic colonies, bacitracin sensitivity and catalase negativity test. Result: Altogether 18 (9%) BHS isolates were identified from 200 samples, out of which 11 (5.5%) isolates were from males and 7 (3.5%) were from females. Conclusion: This result highlights the current situation of GABHS throat infection in school children of Kirtipur
