Abstract
Doxycycline (α-6-deoxy-oxytetracycline) was tested against various bacteria of recent clinical origin with 30-μg discs. The antibiotic susceptibility of these bacteria to commonly used antimicrobial agents was also established. Those bacteria which responded with equivocal zones of inhibition about the tetracycline compounds were tested by the tube dilution technique. Staphylococci and enterococci consistently displayed greater in vitro susceptibility to doxycycline than to tetracycline or demethylchlortetracycline.
