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 ]
Cereulide is a toxin produced by some strains of Bacillus cereus, Bacillus megaterium and related species. It is a potent cytotoxin that destroys mitochondria. It causes nausea and vomiting. Cereulide acts as ionophore with a high affinity to potassium cations.

Priestia, as of May 2021, contains 10 species with validly published names. [3] This genus was identified as a monophyletic clade and phylogenetically unrelated to other Bacillus species in studies examining the taxonomic relationships within Bacillus. [1]
From E. coli traced to slivered onions on McDonald's Quarter Pounders to mass recalls of frozen waffles due to listeria risk, foodborne illness seems ever-present in the headlines.
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Hand, foot and mouth disease (HFMD) A diagnosis usually can be made by the presenting signs and symptoms alone. If the diagnosis is unclear, a throat swab or stool specimen may be taken. Medications are usually not needed as hand, foot, and mouth disease is a viral disease that typically resolves on its own. Under research [15] [16] Sin Nombre ...
An endospore stain of the cell Bacillus subtilis showing endospores as green and the vegetative cell as red Phase-bright endospores of Paenibacillus alvei imaged with phase-contrast microscopy. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota.
