Group A streptococci in children with acute pharyngitis in Sousse, Tunisia
AbstractA 1-year prospective study in 2 paediatric outpatient clinics in Sousse, Tunisia, aimed to determine the presence of group A streptococci in acute pharyngitis cases and carriers, and the distribution of the serotypes and biotypes. Group A streptococci were found in 9.0% of throat swabs from 155 controls and 17.7% from 474 patients [P < 0.05]. Of 43 strains isolated from patients and submitted for typing, 15 different types were identified, the most common being M75 [14 strains; 32.5%], M9 [6 strains; 14.0%], M76 [5 strains; 11.6%] and M12 [4 strains; 9.3%]. Three strains were non-typeable [7.0%]. Biotyping of the strains showed 3 predominant biotypes: biotype 3 [n = 14], biotype 2 [n = 11], and biotype 1 [n = 7]

Boukadida, J.; Hannechi, N.; Boukadida, N.; Ben Said, H.; El Mherbech, H.; Errai, S. (2003)To determine the role and importance of beta-haemolytic streptococci in acute pharyngitis and its relative susceptibility to antibiotics, we cultured samples from 143 patients [age range: 3-72 years] who presented over a 5-month period in 2001 at three primary health care centres in Sousse, Tunisia. The cultures yielded 80 beta-haemolytic streptococci [59 group A streptococci and 21 non-group A streptococci]. All strains were susceptible to benzylpenicillin, amoxicillin, chloramphenicol, rifampicin and pristinamycin. Susceptibility was variable ...
