THE FREQUENCY OF RESISTANCE TO ERYTHROMYCIN IN GROUP-A STREPTOCOCCI IN ANKARA

The frequency of resistance to erythromycin of group A beta-haemolytic streptococci in the last 7 years was determined in three medical cent res in Ankara, While all group A beta-haemolytic streptococci strains were susceptible to penicillin, a gradual increase in resistance to er ythromycin until 1992 was observed. However, a substantial increase in erythromycin resistance occurred in 1993 when newer macrolides became available and were widely used in the latter part of 1992. Conclusion The data show that frequent testing for resistance to erythromycin of group A beta-haemolytic streptococci is required for the use of this antibiotic in our country.
