Priestia megaterium [1] (Bacillus megaterium prior to 2020) [2] is a rod-like, Gram-positive, mainly aerobic, spore forming bacterium found in widely diverse habitats. [ 3 ] [ 4 ] It has a cell length up to 100 μm and a diameter of 0.1 μm, which is quite large for bacteria. [ 5 ]
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.

Bacillus megaterium for example, synthesizes a capsule composed of polypeptide and polysaccharides. Bacillus anthracis; Streptococcus pyogenes synthesizes a hyaluronic acid capsule. Streptococcus pneumoniae [20] has at least 91 different capsular serotypes. [21] These serotypes are the basis for the pneumococcal vaccines.
Foodborne botulism is a potentially deadly condition that’s caused by eating food contaminated with botulinum toxin, a potent toxin that attacks the body’s nervous system.The disease is ...
Two invalidly published species, "Bacillus pseudoflexus" and "Bacillus zanthoxyli", are also found to group with other members of Priestia in phylogenetic trees, as well as share the same molecular markers in the form of CSIs. [1] Their transfer was not officially proposed, though, due to the lack of culture strain information.
The body is continually exposed to many species of bacteria, including beneficial commensals, which grow on the skin and mucous membranes, and saprophytes, which grow mainly in the soil and in decaying matter. The blood and tissue fluids contain nutrients sufficient to sustain the growth of many bacteria.
In addition, the genus Bacillus has been restricted to include only species closely related to Bacillus subtilis and Bacillus cereus. [ 1 ] [ 3 ] The name Cytobacillus can be broken down into the prefix "cyto-" (from the Greek noun kytos , referring to hollow, vessel, jar or a cell in biology) and the suffix "-bacillus" (from the Latin noun ...
