Abstract:
This study was done to investigate the rate of Streptococcus pyogenes or Group A streptococcus (GAS) and antimicrobial susceptibility pattern of isolates in asymptomatic school children in Kathmandu and Sindhuli districts. Pharyngeal swabs were collected and subjected to crystal violet blood agar (CVBA). A total of 468 asymptomatic school aged children were included and 51 (10.8%) were found to be GAS carrier. Among the isolates 23 (12.0%) were from boys where 28 (10.1%) were from girls. The GAS colonization rate was statistically insignificant (P > 0.05) with sex and age sub-group, although the rate was slightly higher among the boys and age sub group 10-12 years. GAS was significantly higher in large family size (p < 0.05). Out of 51 isolates, 100.0% isolates were sensitive to antibiotic penicillin where as 7.8% and 5.8% isolates were resistant to antibiotic ampicillin and erythromycin respectively.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
