Hemolysin BL (HBL) is the multi-component enterotoxin causing diarrheal type of Bacillus cereus food poisoning. The hbl operon of B. cereus was divided into 4 coding sequences (CDS) and identified as hblC, hblD, hblA and hblB genes consisting of 1,319, 1,221, 1,128 and 1,401 nucleotides encoding proteins of 439, 406, 375 and 466 amino acids with predicted sizes of 49.3, 43.8, 41.7 and 52.3 kDa,...

Bacillus cereus infection is rarely associated with actual infection and for this reason single positive blood culture is usually regarded as contamination . However it may cause a number of infections, such catheter-related bloodstream infections. Significant catheter-related bloodstream infections (CRBSI) caused by Bacillus spp. are mainly due to B. cereus and have been predominantly reported...

Injection of a Japanese cedar pollen suspension into silkworm hemolymph kills the silkworms. A certain species of bacteria proliferated in the hemolymph of the dead silkworms. A 16S rDNA analysis demonstrated that the proliferating bacteria were Bacillus cereus, Bacillus thuringiensis, Bacillus weihenstephanensis, and Bacillus amyloliquefaciens. Among them, B. cereus, B. thuringiensis, and B. w...

Matrix-assisted laser desorption-ionization (MALDI) time-of-flight mass spectrometry was used to characterize the spores of 14 microorganisms of the Bacillus cereus group. This group includes the four Bacillus species B. anthracis, B. cereus, B. mycoides, and B. thuringiensis. MALDI mass spectra obtained from whole bacterial spores showed many similarities between the species, except for B. myc...

In this study rapid pyrosequencing was used for identification and fatty acid analysis of enterotoxic and non-enterotoxic Bacillus cereus. Presumptive B. cereus strains were isolated from ready-to-eat foods on mannitol-egg yolk-polymyxin agar and the identification was made based on the characteristics of B. cereus sp. Pyrosequencing was carried out on amplicons derived from 3 different 16S gen...

Among the facultative bacteria capable of growth on mesquite wood which were isolated from the asceptically dissected hind-gut of the termite Reticulitermes hesperus were two strains of Bacillus cereus, one strain each of Arthrobacter, Alcaligenes and Serratia, and a very small Gram-negative fermentative rod. The B. cereus strains, the Serratia marcescens strain and the Arthrobacter sp. grew we...
