Group A Beta Haemolytic Streptococci Isolated From Throat Samples in Children Applying to Pediatri Polyclinic and Their Antibiotic Susceptibility

Abstract

INTRODUCTION: A group beta-haemolytic streptococi (AGBHS) are the most common bacterial cause of these infectionms which can be complicated by severe nonsuppurative sequelae, including acut rheumatic fever and glomerulonephritis. Streptococal infections arde hyperendemic in our region. METHODS: Throat samples were taken from 200 children with symptoms of the upper respiratory tract infection, at the age of 0-10 years, Patients were divided into 0-2, 2-6, 6-10 age groups. 30 children without having upper respiratuary tract complain of 0-6 years were included in the study as control group. Streptococci strains were identified with conventional methods. Antibiotic sensivitiy was evaluated by the disk diffusion method. RESULTS: All samples taken, 51 isolated were confirmed as beta haemolytic streptococi (BHS), accounting for 25.5 %of the total in the patient group and control group (5) isolated were BHS (16.7 %). Distribution of isolated positive of BHS among patients of different ages were 28.3%of in 0-21 age group, 27.5 %in 2-6 age group, and 20.0 in 6-10 age group. Of total 51 BHS isolated from patients group, 36 (70.6 %) isolated and 5 (60 %) of the control group were identified as AGBHS. AGBHS among the different age group had a similar distribution pattern with 70.6 %in 0-2 age group, 77.3 %in 2-6 age group, 58.3 %in 6-10 age group, respectively. Prevalance of AGBHS was found 60.6 %in control group. All isolated were susceptible to penicilin, ampicillin and amoksicillin.Resistance was found to 13.9% erythromycin and 16.7% ofloxacin, respectively. DISCUSSION AND CONCLUSION: Infection rates and resistance to antibiotics should be investigated periodically.
