Beta-haemolytic streptococci in acute pharyngitis.
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 in erythromycin, tetracycline, fosfomycin, telithromycin and levofloxacin. Minimum inhibitory concentrations were determined by E-test for penicillin, erythromycin and levofloxacin. Our results confirm that penicillin is still the reference treatment for acute pharyngitis. However, to minimize the potential for complications arising from its use, continued vigilance is required.
