|Categories:||Causes hemolysis; spore forming; motile|
|Etymology:||Genus name: small rod|
Species epithet: wax colored
|Type Strain:||ATCC 14579 = CCUG 7414 = NCTC 2599|
||Large, opaque, grey-yellow, granular, flat colonies (diameter 5-10 mm). Most strains produce a clear broad zone of hemolysis on blood agar.|
||Large (1 x 5-10 µm) motile rods, centrally located endospores can sometimes be seen as uncolored regions after Gram staining of cells from older cultures. May form spores.|
|Gram +/Gram -:||G+ (Cells from older cultures can appear as G - because the cell wall degenerates)|
|Other Enzymes:||Lecithinase +|
|Fermentation of carbohydrates:||
||MYP agar is often used for confirmation of suspected B. cereus colonies from food samples.|
|Disease:||Food poisoning, can occasionally be isolated from cattle with mastitis.
|16S rRNA Seq.:|
||About 250 species have been described within the genus Bacillus. B. cereus is very closely related to Bacillus anthracis and Bacillus thuringiensis.|
|The revised taxonomy of the mollicutes|
The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.Published 2021-11-25. Read more...
