Cc. Kuo et al., IN-VITRO ACTIVITIES OF AZITHROMYCIN, CLARITHROMYCIN, AND OTHER ANTIBIOTICS AGAINST CHLAMYDIA-PNEUMONIAE, Antimicrobial agents and chemotherapy, 40(11), 1996, pp. 2669-2670
The in vitro susceptibilities of Chlamydia pneumoniae isolates to macr
olide, tetracycline, and quinolone antibiotics were determined. Tetrac
ycline, clarithromycin, and erythromycin had the lowest MICs in the fi
rst cell culture passage. Azithromycin required the lowest concentrati
on for complete inhibition of inclusion formation on the second pass i
nto antibiotic-free medium, likely reflecting its high intracellular c
oncentrations.
