Investigation of Penicillin Tolerance and Erythromycin Resistance in Group A-Beta Hemolytic Streptococci Isolated From Throat Cultures. Mikrobiyoloji Bülteni, 32(1), 9-13.0374-9096https://hdl.handle.net/20.500.12395/16823In this study, the penicillin tolerance and erythromycin resistance of 100 strains of group A beta hemolytic streptococci, isolated from throat cultures of patients who admitted to outpatient clinics of Selcuk University Medical School, were investigated by microdilution method. If the ratio of Minimal Bactericidal Concentration to Minimal Inhibitory Concentration (MBC/MIC) were higher than 32 ?g/ml, the strains have been evaluated as penicillin tolerant, if the MIC was equal and/or higher than 8 ?g/ml, the strains have been evaluated as erythromycin resistant. As a result, none of the strains was found as penicillin tolerant, whereas 4% of strains were found as erythromycin resistant.trinfo:eu-repo/semantics/closedAccessErythromycin ResistanceGroup a Beta Hemolytic StreptococciPenicillin ToleranceArticle321913Q4
