Penicillin,ciprofloxacin(and other quinolones),doxicyclin,ampicillin,imipenem.clindamycin, clarithromycin,vancomycin,chloramphenicol,rifampicin are effective antimicrobials. Antimicrobial therapy for 60 days is recommended.Human anthrax vaccine is available. Administration of anti-protective antigen(PA) antibody in combination with ciprofloxacin produced 90%-100%survival.The combination of CPG-adjuvanted anthrax vaccine adsorbed(AVA) plus dalbavancin significantly improved survival.展开更多
