Microbiological profile of common bacterial isolates from acute tonsillitis in pediatric age group patients

Ashish Sharma, Naga Babu Pyadala


Background: The paediatric age group are more prone to tonsillitis. The management of tonsillitis mainly based on understanding of microbiological and pathological features. This study aimed to discuss the microbiological profile of acute tonsillitis in children.

Methods: Children fewer than 16 years age group was included in this study and the children underwent tonsillectomy or in antibiotics for at least one month were excluded from study. The throat swabs were taken for microbiological diagnosis.

Results: A total of 150 children were diagnosed as acute tonsillitis during the period of 1 year from January 2019 to December 2019. The mean age group of children were 9.6 years. There were total 70 males and 80 females. The most common isolates were Streptococcus viridians group, Group A β-hemolytic Streptococci. There were only 3 cases with polymicrobial growth. The histopathological examination reported acute tonsillitis with follicular hyperplasia in all children.

Conclusions: The understanding of microbiological profile could help in management of acute tonsillitis. The pathological profile can help us to identify the organisms which are difficult to culture.
