Gram positive (or positive only in early stages of growth), rod shaped cells, mostly straight, 0.3-2.2 x 1.2-7
μm. Majority motile with lateral flagella. Heat-resistant endospores formed. Chemoorganotrophs; strict
aerobes or facultative anaerobes. Some characters (like vegetative cell wall, glucose fermentation, growth
temperature, etc.) are very variable.

According to Genersch et
al. 2006,
P. larvae subsp.
and P. larvae
subsp. larvae
reclassified as a single

Strains of B. carotarum, B.
, B. cobayae, B.
, B. maroccanus
B. macroides were
reclassified as

According to Wang et al.
B. mojavensis  is an
earlier heterotypic synonym
Bacillus axarquiensis  
Bacillus malacitensis.
