===Overview===
 
 
*Mostly non-pathogenic environmental organisms
 
*''[[Bacillus anthracis]]'' causes anthrax
 
*Anthrax is a severe disease affecting all mammals worldwide
 
*Ruminants are highly susceptible to anthrax, dying of a septicaemic form
 
*Pigs and horses are moderately susceptible, but carnivores are fairly resistant
 
*''[[Bacillus licheniformis]]'' may cause shoradic abortions in cattle and sheep
 
*''[[Bacillus cereus]]'' causes food poisoning in humans and mastitis in cows
 
 
 
===Characteristics===
 
 
*Large, Gram positive rods
 
*Produce endospores
 
*Aerobes or facultative anaerobes
 
*Grow on non-enriched media
 
*Motile
 
*Catalase positive, oxidase negative
 
*''Bacillus anthracis'' colonies are up to 5mm diameter, flat, dry, grey, with a ground-glass appearance; curled outgrowths from the edge of the colony give a 'medusa head' appearance; non-haemolytic (differentiate from ''Bacillus cereus'')
 
*''Bacillus licheniformis'' forms dull, rough, wrinkled colonies, with hair-like outgrowths
 
*Biochemical tests for identification
 
*Can often tolerate adverse environmental conditions
