چکیده
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.

Identification of surface proteins involved in the adhesion of a probiotic Bacillus cereus strain to mucin and fibronectin.
Several Bacillus strains isolated from commercial probiotic preparations were identified at the species level, and their adhesion capabilities to three different model intestinal surfaces (mucin, Matrigel and Caco-2 cells) were assessed. In general, adhesion of spores was higher than that of vegetative cells to the three matrices, and overall strain Bacillus cereus(CH) displayed the best adhesi...
متن کاملCharacterization of Bacillus probiotics available for human use.
Bacillus species (Bacillus cereus, Bacillus clausii, Bacillus pumilus) carried in five commercial probiotic products consisting of bacterial spores were characterized for potential attributes (colonization, immunostimulation, and antimicrobial activity) that could account for their claimed probiotic properties. Three B. cereus strains were shown to persist in the mouse gastrointestinal tract fo...
متن کاملProbiotic Bacillus cereus Strains, a Potential Risk for Public Health in China
Bacillus cereus is an important cause of foodborne infectious disease and food poisoning. However, B. cereus has also been used as a probiotic in human medicine and livestock production, with low standards of safety assessment. In this study, we evaluated the safety of 15 commercial probiotic B. cereus preparations from China in terms of mislabeling, toxin production, and transferable antimicro...
متن کاملAntagonistic Activity of Bacillus Cereus against Human and Fish Pathogenic Bacteria
The most commonly used probiotic is usually characterized as gram positive, non motile, non sporulating bacteria that produce lactic acid as their main by product due to fermentation. The Morphological, Biochemical, Acid and Bile salt tolerance, Haemolytic test are used for identification and conformation of probiotic bacteria. Isolated Bacillus cereus was analyzed using the agar diffusion meth...
متن کاملProbiotic Activity of a Bacterial Strain Isolated from Ancient Permafrost Against Salmonella Infection in Mice.
Bacillus cereus strain F, collected from relict permafrost located in Siberia, was analyzed for probiotic activity in the mouse Salmonella enterica model. Viable bacterial cells were found in frozen soils taken at Mammoth Mountain in Yakutia from a depth below the level of seasonal thawing. Geological data indicated the absence of a thawing within millions of years of deposited soils, which hel...
