| − | ===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
