Respiratory anthrax, in the absence of early antibiotic treatment, is a fatal disease. This study aimed to test
the efficiency of antibiotic therapy in curing infected animals and those sick with anthrax. Postexposure
prophylaxis (24 h postinfection [p.i.]) of guinea pigs infected intranasally with Bacillus anthracis Vollum spores
with doxycycline, ofloxacin, imipenem, and gentamicin conferred protection. However, upon termination of
treatment, the animals died from respiratory anthrax. Combined treatment with antibiotics and active vaccination
with a protective antigen-based vaccine leads to full protection even after cessation of treatment.
Delaying the initiation of antibiotic administration to over 24 h p.i. resulted in treatment of animals with
anthrax exhibiting various degrees of bacteremia and toxemia. Treatment with doxycycline or ciprofloxacin
cured sick guinea pigs and rabbits exhibiting bacteremia levels up to 105 CFU/ml. Addition of anti-protective
antigen (PA) antibodies augmented the efficiency of protection, allowing the cure of guinea pigs and rabbits
with 10- to 20-fold-higher bacteremia levels, up to 7  105 CFU/ml and 2  106 CFU/ml, respectively.
Treatment with ciprofloxacin and a monoclonal anti-PA antibody rescued rabbits with bacteremia levels up to
4  106 CFU/ml. During antibiotic administration, all surviving animals developed a protective immune
response against development of a fatal disease and subcutaneous challenge with Vollum spores. In conclusion,
these results demonstrate that antibiotic treatment can prevent the development of fatal disease in respiratoryanthrax-
infected animals and can cure animals after disease establishment. A therapeutic time window of 40 h
to 48 h from infection to initiation of efficient antibiotic-mediated cure was observed.
