Bacillales

Bacillales, from Latin "bacillus", meaning "little staff, wand", are an order of Gram-positive bacteria, placed within the Bacillota. The Bacillales are the most productive order of the phylum "Firmicutes". Representative genera include Bacillus, Listeria and Staphylococcus.

Staphylococcaceae, from Ancient Greek σταφυλή (staphulḗ), meaning "bunch of grapes", and κόκκος (kókkos), meaning "sphere", are a family of Gram-positive bacteria that includes the genus Staphylococcus, noted for encompassing several medically significant pathogens.

Bacillaceae, from Latin "bacillus", meaning "little staff, wand", are a family of gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. Motile members of this family are characterized by peritrichous flagella. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are not pathogenic, but certain Bacillus species are known to cause disease in humans.

The Paenibacillaceae are a family of Gram-positive bacteria.

Gemella is a genus of Gram-positive bacteria that thrive best at high partial pressure of CO2.

The Alicyclobacillaceae are a family of Gram-positive bacteria. All members of this family are aerobic and form endospores.

The Thermoactinomycetaceae are a family of Gram-positive endospore-forming bacteria.

Sporosarcina is a genus of bacteria.

The Sporolactobacillaceae are a family of Gram-positive bacteria including the genera Sporolactobacillus and Tuberibacillus.

Pasteuria is a genus of mycelial and endospore-forming, nonmotile gram-positive bacteria that are obligate parasites of some nematodes and crustaceans. The genus of Pasteuria was previously classified within the family Alicyclobacillaceae, but has since been moved to the family Pasteuriaceae.

The Caryophanaceae is a family of Gram-positive bacteria. In 2020, the now defunct family Planococcaceae was merged into Caryophanaceae to rectify a nomenclature anomaly. The type genus of this family is Caryophanon.

Sporolactobacillus is a genus of anaerobic, endospore-forming, gram-positive, motile, rod-shaped, lactic acid bacteria.

Tumebacillus is a genus of Gram-positive, rod-shaped, spore-forming bacteria. Members of the genus can be motile or non-motile, and form white or yellow colonies on R2A agar.
