<< Anthrax, contagious disease of warm-blooded animals, including humans, caused by the bacterium Bacillus anthracis. One of the oldest known diseases, it was once epidemic and still appears in many world areas, but only sporadically in the western and southern United States. It was the first disease for which the causative organism was isolated, by C. J. Davaine in 1863, for which a pure culture was obtained, by Robert Koch in 1876, and for which an effective vaccine was developed, by Louis Pasteur in 1881.
Animals acquire the disease from drinking water draining from contaminated soil, in which the infectious bacteria may live for years; from eating infected carcasses and feedstuffs; and from the bites of bloodsucking insects. The disease, sometimes manifested by staggering, bloody discharge, convulsions, and suffocation, may be fatal almost immediately in acute cases and within three to five days in subacute cases. Death is caused by toxemia. The disease can be prevented by immunization, and in animals that have not been vaccinated, it can be treated with antibiotics.

I hope this settles any rattled nerves.
