In vitro antimicrobial susceptibilities of strains of Yersinia pestis
Smith MD., Vinh DX., Nguyen TT., Wain J., Thung D., White NJ.
The in vitro activities of 14 antimicrobial agents were determined for 78 strains of Yersinia pestis. The most active antibiotics were ceftriaxone and ciprofloxacin, followed by ofloxacin and ampicillin. The agents traditionally used for the treatment of plague (streptomycin, tetracycline, and chloramphenicol) were considerably less active. Azithromycin showed poor activity against all strains.
