BACKGROUND Bacillus species are spore-forming bacteria that are ubiquitous in the environment and display a range of virulent and avirulent phenotypes. This range is particularly evident in the Bacillus cereus sensu lato group; where closely related strains cause anthrax, food-borne illnesses, and pneumonia, but can also be non-pathogenic. Although much of this phenotypic range can be attribute...

objective: bacillus cereus (b. cereus) is a gram-positive, spore-forming bacteria widely distributed in the environment. this bacteria is an opportunistic human pathogen that can cause diarrheal and emetic types of food poisoning. the diarrhea type of food poisoning can be caused by hemolysin bl (hbl), non-hemolytic (nhe), and cytotoxin k enterotoxins. rice is commonly contaminated with b. cere...

AIMS To determine the contribution of potential modes of action of a Bacillus cereus aquaculture biological control agent in inhibition of the fish pathogen, Aeromonas hydrophila. METHODS AND RESULTS When B. cereus was tested in plate well inhibition studies, no production of antimicrobial compounds was detected. Bacillus cereus had a high growth rate (0.96 h(-1)), whereas Aer. hydrophila con...

Bacillus cereus is a rare cause of endocarditis, typically associated with intravenous drug abuse, rheumatic heart disease, prosthetic heart valves, pacemakers, or immunodeficiency. We present the first case of native valve Bacillus cereus endocarditis with no apparent risk factors. The patient had a fulminant course requiring emergent valve replacement.

The purpose of this study was to assess the efficacy of a probiotic containing Bacillus cereus var. Toyoi spores (Toyocerin) and benzoic acid (VevoVitall) on growth performance and diarrhoea in weaning pigs, against negative controls. The trial groups were as follows: (a) NC group (Negative Controls): No treatment (b) TOYO group: Same feed as in the controls plus Toyocerin at a dose of 1 x 10(9...

A selective medium that allows for growith of Bacillus anthracis while inhibiting common contaminants and closely related sporeformers (e.g., Bacillus cereus) is described. This medium contains polymyxin, lysozyme, dLsodium ethylenediamine tetraacetate, and thallous acetate as the selective ingredients. It may also be used as a differential medium to distinguish B. anthracis from A. cereus and ...

Representative strains of the Bacillus cereus group of bacteria, including Bacillus anthracis (11 isolates), B. cereus (38 isolates), Bacillus mycoides (1 isolate), Bacillus thuringiensis (53 isolates from 17 serovars), and Bacillus weihenstephanensis (2 isolates) were assigned to 59 sequence types (STs) derived from the nucleotide sequences of seven alleles, glpF, gmk, ilvD, pta, pur, pycA, an...

Antibacterial activities of zinc oxide nanoparticles against two toxigenic bacteria isolated from Egyptian food (Bacillus cereus and Staphylococcus aureus) were investigated in this study. Fifteen samples of five types of sandwiches (Falafel with salad, falafel without salad, bean, sausage and beef luncheon) were purchased from El-Mahla El-Kobra restaurants Tanta, Egypt and investigated for som...

All 47 food-borne isolates of Bacillus cereus sensu stricto, as well as 10 of 12 food-borne, enterotoxigenic isolates of Bacillus thuringiensis, possessed appendages. Spores were moderately to highly hydrophobic, and each had a net negative charge. These characteristics indicate that spores of food-associated B. thuringiensis and not only B. cereus sensu stricto have high potential to adhere to...
