Multiplying vegetative cells enter the bloodstream and may reach levels of gene product, edema factor (EF), to receptor-bound PA (53).

However, most of the agents considered significant threats either have been eradicated or rarely infect humans alive today.

As such, vaccine efficacy cannot be determined in human clinical trials but must be extrapolated from experimental animal models.

By increasing c AMP concentrations in neutrophils, ET inhibits phagocytosis and blocks particulate as well as phorbol myristate acetate-induced respiratory burst responses (64).

ET also differentially regulates macrophage responsiveness to lipopolysaccharide-induced production of tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) (40).

(i) The enhancement of survival in vaccinated non-human primates and rabbits challenged with spores is clearly related to the prevention of mortality in exposed humans.

(ii) More than one species that is expected to react with a response predictive for human beings is used.

This mysterious disease became a significant problem among British wool sorters and German ragpickers following the introduction of mohair from Turkey and alpaca from Peru to Europe in the 1830s (13).

Inhalation anthrax has a clinical incubation period of 1 to 6 days, during which nonspecific symptoms of malaise, fatigue, myalgia, and fever develop.

ET is an adenylate cyclase that increases intracellular cyclic AMP (c AMP) levels in susceptible cells.
