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.
