title: In vitro evaluation of CP-62,993, erythromycin, clindamycin, and tetracycline against Chlamydia trachomatis.
abstract: The antimicrobial activity of CP-62,993 against four Chlamydia trachomatis isolates was compared with those of erythromycin, clindamycin, and tetracycline. The MIC of CP-62,993 was 0.26 to 1.02 micrograms/ml for 100% inclusion inhibition and 0.031 to 0.063 microgram/ml for 50% inclusion inhibition. With pharmacokinetic and antimicrobial studies demonstrating prolonged half-life and in vitro effectiveness, CP-62,993 may make possible a single, short-course treatment regimen for C. trachomatis infection.
