Unless engineered, B. anthracis is susceptible to penicillin, amoxicillin, chloramphenicol, doxycycline, erythromycin, streptomycin, ciprofloxacin, and other quinolones. It is resistant to ceftriaxone and other 3 rd generation cephalosporins. Treatment for anthrax consists of a multi-drug regimen of ciprofloxacin, and at least one other agent of vancomycin, chloramphenicol, or penicillin [14] . For inhalational anthrax, the recommended regimen is ciprofloxacin or doxycycline, plus clindamycin and rifampin. Doxycycline and clindamycin, however, exhibit poor cerebrospinal fluid penetration and should be avoided in cases of anthrax meningoencephalitis. The addition of rifampin serves for the prevention or treatment of neurological manifestations [14] in cases treated with doxycycline or clindamycin. Treatment duration is long; a 60-day course is not unusual, given that spores can remain dormant for a long time. Corticosteriods are recommended in all patients who have pulmonary edema, respiratory failure, and meningitis [12] . In anthrax meningitis, steroids have been reported to improve survival [26] ; however, their use is controversial in adults, but it has improved outcome in children.
