Abstract (2. Language): 
Antimicrobial resistance in beta- hemolytic streptococci isolated from respiratory tract infec-tions. Between 1997 and 2001, a total of 103 beta- hemolytic streptococcus isolated from pati-ents were examined. Group determinations were peıformed by presumptİve İdentİficatİon and latex agglutination tests. Isolation results of groups were as foîlows A (62), B (5), C (6), D (4), F (14) and G (12). In susceptİbİIity assays usİng disk diffusion and deteeting MIC values (E-Test), ali straİns wcrc found to be susceptible to penicillin (one moderately susceptible in gro¬up D), but 3 to eryfhromycin (one moderately susceptible), 2 to chlarithromycin, 11 to azith-romyein (8 moderately susceptible), 5 to cİprofîoxacin (1 moderately susceptible) were detec-ted to be resistant and 2 moderately susceptible to levofloxacine. Only one strain was found to be moderately susceptible to chlarithromycin by disk diffusion but resistant by E test.
Abstract (Original Language): 
1997-2001 yıllarında çocuk ve erişkin hastalardan izoîe edilen 103 beta hemolitik streptokok suşu incelenmiştir. Tahmini tanı ve latcks aglutinasyon yöntemleri uygulanarak yapılan grup-landırmada suşlann 62'si, 14'ü F, 12'si G, 6'sı C, 5'İ B, 4'ü D grubu olarak belirlenmiştir. Antibiyotiklere duyarlılıklar disk difüzyon ve MİK değerleri (E test) belirlenerek yapılmış ve suşlann tümü penisiline duyarlı (D grubundan 1 suş orta duyarlı), eritromisine 3(l'i orta duyarlı), klaritromisine 2, azitromisine ll(8'i orta duyarlı), siprofloksasine 5 (l'i orta duyarlı) suş dirençli, levofîoksasine 2 suş orta duyarlı bulunmuştur. Dİsk difüzyon yöntemi ile klaritromisine orta duyarlı bulunan yalnız 1 suş MİK değerine göre dirençli kabul edilmiştir.
