The study population was examined clinically for the presence or absence of signs and symptoms of pharyngitis, throat swab culture and the isolation of group A and other groups of β _hemolytic streptococci was confirmed using serogroping strep test. The result of this study show that the isolation rate of β _hemolytic streptococci was 47.66% and of group A was 23.66% among the study population. The isolation was higher in the following situations (4_8) year olds, among children lived in crowded conditions, among children with recurrent tonsillitis. The antimicrobial susceptibility testing revealed that the highest sensitivity rate of the group A streptococci was to Azithromycin (80.3%) followed by Penicillin G (77.5%) and Ceftriaxone (74.7%). Gentamycin was the least effective antimicrobial agent tested.
