    Classification. Here I will give you the entire classification of Bacillus cereus, some information on what makes the taxonomic class unique, along with other examples of organisms in the same classification!Some may ask 'What do you mean by classification?' Well, classification is a method of organizing different organisms into different groups based on similar characteristics. Bacillus aerius is a species of bacteria first isolated from cryogenic tubes used for collecting air samples from high altitudes, hence its name. Its type strain is 24K T (=MTCC T =JCM T).Family: Bacillaceae.

Bacillus cereus strain F was isolated and cultured from a sample of permafrost, aged presumably about 3 million years, on the Mammoth Mountain (62°56′N, °59′E). These genome data provide the basis to investigate Bacillus cereus F, identified as a long-term survivor of the extremely cold and close environment.

Bacillus cereus is a gram-positive aerobic or facultatively anaerobic spore-forming rod. It is a cause of food poisoning, which is frequently associated with the consumption of rice-based dishes. The organism produces an emetic or diarrheal syndrome induced Cited by: Bacillus cereus is a Gram-positive, rod-shaped, facultatively anaerobic, motile, beta-hemolytic, spore forming bacterium commonly found in soil and food.

The specific name, cereus, meaning "waxy" in Latin, refers to the appearance of colonies grown on blood strains are harmful to humans and cause foodborne illness, while other strains can be beneficial as probiotics for : Bacilli.

ABSTRACT. Bacillus cereus CenBiot fulfilled the requirements to be used as probiotic. The spores showed D 80 of 14 hs, inhibited Escherichia coli and Yersinia pseudotuberculosis after 24 hs in associative culture, were innocuous for suckling and adult mice and were not inhibited by antibiotics at low concentrations.

Key words: probiotic, Bacillus cereus. Bacillus cereus is associated primarily with 2 toxin-mediated foodborne illnesses, emetic and diarrheal, but it also can cause invasive extraintestinal infection.

The emetic syndrome develops after a short incubation period, similar to staphylococcal foodborne illness. It is characterized by nausea, vomiting, and abdominal cramps, and diarrhea can follow in up to a third of patients. Bacillus cereus is a causative agent in both gastrointestinal and in nongastrointestinal infections.

Enterotoxins, emetic toxin (cereulide), hemolysins, and phoshpolipase C as well as many enzymes such as beta-lactamases, proteases and collagenases are known as potential virulence factors of B. cereus.A special surface structure of B.

1 CHAPTER ONE INTRODUCTION Bacillus cereus is spore forming, aerobic to facultative, gram-positive, motile rod, ubiquitously opportunistic pathogen, frequently isolated from soil and growing plants, but it is also well adapted for growth in the intestinal tract of insects and mammals.

Bacillus cereus is an ubiquitary microorganism that may cause food borne disease. Pathogenicity, however, depends on various characteristics such as the ability to form (entero)-toxin(s) that can not be detected by microbiological methods. Further characterization of pathogenic properties is not only of importance to identify strains from.

Trophic Level-Bacillus cereus is a heterotrophic feeder. Heterotrophic in Latin translates to hetero= "another" trophic="nutrition". This means that to be heterotrophic, you feed on other organisms to acquire you nutrition. Also, Bacillus cereus can be classified as a parasitic organism, because it utilizes hosts such as humans and insects.a.
