Background and objectives: Group A β-Hemolytic Streptococci are the most prevalent pathogenic bacteria that
can cause rheumatic fever and acute glomerulonephritis in adolescents so its
correct diagnosis and treatment is very important.
This study was done with multi stage random sampling method between threehundred
12-14 year old healthy students in Aras Free Zone guidance schools.
Material and Methods :Sixty seven group A β-Hemolytic Streptococcus (GABHS) strains were isolated and
were tested with disc diffusion method against sixteen antibiotics including Penicillin,
Erythromycin and some second line drugs such as Amoxicillin, Ampicillin, Coamoxiclav, Tobramycin, Gentamicin, Clindamycin, Vancomycin, Tetracycline,
Cotrimoxazole, Cloxacillin, Cephalothin, Cephalaxin, Cefazolin, Cefixime.
Results: This study indicated that of 300 students, %22 were healthy carriers ofGABHS. Of 67
healthy carriers, 17 cases (%27) were female students of first base class thatwas the
highest rate, whereas 4 cases (%8.5) were female students of second base class that was
the lowest rate.
Conclusion: All of GABHS strains (%100) were sensitive to Penicillin and resistance to
Cotrimoxazole and Clavulanic acid were detected up to %92 and %89 respectively.
Our results showed that prescription of second line drugs must be prescripted more
cautiously.
