摘要

Bacillus anthracis spores, the dormant metabolically inactive cells, can germinate in the host in the presence of nutrients and become lethal. The vegetative form of B. anthracis produces exotoxins; lethal toxin (LT) made up of protective antigen (PA) and lethal factor (LF) and edema toxin ET made up of PA and edema factor (EF), which inhibit the ability of macrophages to kill spores, cause infections in mammals (Setlow, 2003; Brahmbhatt, et al., 2007) . Anthrax, the disease caused by B. anthracis, can occur according to one of three routes of encounter: (i) cutaneous, the most common, by contact with animals or their products; (ii) inhalation, the most serious; or (iii) gastrointestinal form (Kubler-Kielb, et al. 2008). Each of these forms can lead to a systemic dissemination of the pathogen and promote bacteremia, toxemia, septicemia, and death (Friedlander 1999).
