Abstract:
Objective To evaluate the activities of four demestic macrolides against C. trachomatis and C. pneumoniae by antimicrobiai susceptibility testing. Methods Cell culture and immunoflourescence staining of chlamydial inclusions were used to determine MICs of four demestic macrolides against C. trachomatis and C. pneumoniae. Results MIC (0.5 μg/ml) was found for acylspriramycin,erythromycin and azithromycin against C. trachomatis serovar B while it was 4 μg/ml for acetylspiramycin. Agaisnt C. trachomatis serovar D, MIC was 0.25 μg/mi in both acylspriramycin and azithromycin, and MICs were 0.5 μg/ml and 2 μml in erythromycin and acetylspiramycin, separately. Agaisnt C. pneumoniae TWAR, erythromycin was the most active with MIC≤0. 016 μg/ml, acylspriramycin and azithromycin were the second with same M1C of 0.032 μg/ml. However, acetylspiramycin was less active with 0.5 μg/ml of MIC. Conclusion Except acetylspiramycin, acylspriramycin erythromycin and azithromycin had reliable activities against both C. trachomatis (serovar B and D) and C. pneumoniae.
