Bacillus cereus is a Gram-positive rod-shaped bacterium commonly found in soil, food, and marine sponges. [1] The specific name, cereus, meaning "waxy" in Latin, refers to the appearance of colonies grown on blood agar.
Bacillus cereus biovar anthracis is a variant of the Bacillus cereus bacterium that has acquired plasmids similar to those of Bacillus anthracis. As a result, it is capable of causing anthrax . [ 1 ] [ 2 ] In 2016, it was added to the CDC 's list of select agents and toxins .
Most of the cytotoxic activity of B. cereus isolates has been attributed to the level of Nhe, which may indicate a highly diarrheic potential. [2] The exact mechanism by which B. cereus causes diarrhoea is unknown. Hbl, cytotoxin K (CytK) and Nhe are all putative causes. Both Hbl and Nhe are three-component cytotoxins composed of a binding ...
Later, this B. cereus strain and its relatives were classified as a brand-new species called Bacillus cytotoxicus, which is the thermo-tolerant member of the B. cereus genus. [2] The cytotoxin-K gene is present in approximately 50% of Bacillus cereus isolates, and its expression is regulated by several factors, including temperature and ...
The autopsy found the presence of Bacillus cereus, which was also detected in the pasta. The bacteria is an organism that can cause two types of food poisoning: emetic (meaning to induce vomiting ...
Rice is commonly consumed as food around the world. It occurs in long-, medium-, and short-grained types. It is the staple food of over half the world's population.. Hazards associated with rice consumption include arsenic from the soil, and Bacillus cereus which can grow in poorly-stored cooked rice, and cause food poisoning.
