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...

Among 200 selected dairy samples 50 each of pasteurized milk, cream, butter and paneer were analyzed for the presence of Bacillus cereus the paneer samples were found to have the highest incidence of Bacillus cereus (52.94%) followed by cream sample (29.41%) and pasteurized milk sample (17.64%) however none of the butter samples were found to be contaminated with Bacillus cereus. These isolates...

The bacterial strain Bacillus cereus is closely related to Bacillus thuringiensis, although any genetic relationship between the two strains is still in debate. Using rep-PCR genomic fingerprinting, we established the genetic relationships between Brazilian sympatric populations of B. cereus and B. thuringiensis simultaneously collected from two geographically separate sites. We observed the fo...

materials and methods two-hundred pasteurized (n = 100) and nonpasteurized (n = 100) cheese samples were collected. the initial isolation was performed on pemba specific medium. antibiotic susceptibility testing was performed using several antibiotic disks, according to the guidelines of the clinical laboratory and standards institute. specific primers amplifying the hbla enterotoxin-encoding g...

More evidence has recently been presented suggesting that Bacillus species other than Bacillus anthracis should not be readily discarded as contaminants, especially when isolated from neutropenic patients with cancer1•`3). Although very rare, infections with Bacillus cereus, such as bacteremia, pneumonia or meningitis, are most likely to occur in patients with acute leukemia, and often follow a...

Flagellar antigen of Bacillus cereus H.1 was purified and tested for serodiagnostic antigen by ELISA. The antibody against the flagellar antigen of B. cereus H.1 reacted not only with the homologous specific antigen but also reacted with the flagellar antigens of 23 strains of B. cereus. This common flagellar antigen of B. cereus was found to be due to 61-kDa protein by SDS-PAGE and immunoblot ...

The Bacillus cereus group contains vertebrate pathogens such as Bacillus anthracis and Bacillus cereus and the invertebrate pathogen Bacillus thuringiensis. Microbial biopesticides based on B. thuringiensis (Bt) are widely recognized as being among the safest and least environmentally damaging insecticidal products available. Nevertheless, a recent food poisoning incident prompted a European Fo...

Polyhydroxybutyrate producing bacteria from garden soil were isolated and characterized for their morphological, biochemical properties. Based on their 16S rRNA gene sequences, they were identified as Bacillus mycoides DFC1, Bacillus cereus DC1, Bacillus cereus DC2, Bacillus cereus DC3 and Bacillus cereus DC4. The bacteria were screened for PHB production and compared for the intensity of fluor...

leaf-colonizing strain of Bacillus cereus. and Bacillus thuringiensis and in a subsp. kurstaki expressed in Escherichia coli the NRD-12 isolate of Bacillus thuringiensis Insecticidal activity of the CryIIA protein from

This paper describes a specific, sensitive, semiautomated, and quantitative Hep-2 cell culture-based 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay for Bacillus cereus emetic toxin. Of nine Bacillus, Brevibacillus, and Paenibacillus species assessed for emetic toxin production, only B. cereus was cytotoxic.
