Isolation and Identification of Streptococcus pyogenes from Patients with Tonsillitis in Baghdad Province

Abstract

The present study included isolation of 40 samples of Streptococcus pyogenes from throat clinical samples. The research results indicated that infections of Streptococcus pyogenes in children are greater than in adults. Therefore, clear that the age group patients (5–9) years recorded highest percentage of injury with throat infection (pharyngitis), so that the infection percentage reached to 22 (55.0%). Compared with other age groups which recorded the percentage 8 (20.0%) in the age group (<5) years. While the age group (10–15) years recorded the percentage 10 (25.0%) relatively to all cases. Also this study show the distribution of cases studied according to the gender. The results show that the percentage of male’ infection is higher than females’ infection. So that the number and percentage of males infection were 25 (62.5%), compared with females infection were 15 (37.5%), and in urban are greater than rural, which were 26 (65.0%). While the incidence percentage in rural patients were 14 (35.0%). showed that most of S. pyogenes isolates were resistant against erythromycin, while they sensitive for vacomycin and penicillin by using disc diffusion technique.
