bacillus (bəsĭl`əs), any rod-shaped bacterium or, more particularly, a rod-shaped bacterium of the genus Bacillus. Some bacterium in the genus cause disease, for example B. anthracis is the cause of anthraxanthrax
, acute infectious disease of animals that can be secondarily transmitted to humans. It is caused by a bacterium (Bacillus anthracis) that primarily affects sheep, horses, hogs, cattle, and goats and is almost always fatal in animals.

Bacillus [bah-sil´us] a genus of aerobic or facultatively anaerobic, spore-forming rods, most of which are gram-positive and motile. There are three pathogenic species: B. an´thracis, which causes anthrax; B. ce´reus, a common soil saprophyte that causes food poisoning by the formation of an enterotoxin in contaminated foods; and B. sub´tilis, a common soil and water saprophyte that often occurs as a laboratory contaminant and occasionally causes conjunctivitis. B. subtilis also produces the antibacterial agent bacitracin.

A few species are animal pathogens; some species evoke antibody production. The type species is Bacillus subtilis. [L. dim. of baculus, rod, staff]
