IN-VITRO SUSCEPTIBILITIES OF CHLAMYDIA-PNEUMONIAE STRAINS RECOVERED FROM ATHEROSCLEROTIC CORONARY-ARTERIES

Chlamydia pneumoniae strains have been recovered from arteriosclerotic coronary arteries, but their antibiotic susceptibility profiles have not get been examined, We report in vitro susceptibility data for five cardiovascular C. pneumoniae isolates. These strains did not differ s ignificantly from respiratory strains in their patterns of susceptibil ity to azithromycin, erythromycin, roxithromycin, ofloxacin, doxycycli ne, rifampin, and penicillin G. Roxithromycin was the most active macr olide, and rifampin was the most effective drug overall.
