The cytotoxin CytK produced by Bacillus cereus is believed to be involved in food-borne diseases. The transcriptional activity of the cytK promoter region in a food-poisoning strain was studied using a reporter gene and compared with that in the reference B. cereus strain ATCC 14579. In the food-poisoning strain, cytK is more strongly transcribed, possibly explaining the pathogenicity. The glob...
Variation among isolates of Bacillus anthracis was examined by using restriction fragmentation patterns and the PCR performed with arbitrary and sequence-specific oligonucleotide primers. The patterns were compared with the patterns generated from strains of closely related species belonging to the "Bacillus cereus group" of bacteria, including B. cereus, Bacillus thuringiensis, and Bacillus my...
Typical bacterial strain differentiation methods are often challenged by high genetic similarity between strains. To address this problem, we introduce a novel in silico peptide fingerprinting method based on conventional wet-lab protocols that enables the identification of potential strain-specific peptides. These can be further investigated using in vitro approaches, laying a foundation for t...
Background and purpose: Dairy products often associated with problems such as short shelf life and poor hygiene control. A novel approach is to utilize bacteriocin or bacteriocin producer strains, to control undesirable micro flora as Listeria monocytogenes and Bacillus cereus in foods. Hence, we studied the effect of nisin like producing Lactococcus lactis against Listeria monocytogenes and ...
با توجه به گسترش عفونت¬های قارچی و ظهور گونه¬های مقاوم به درمان، یافتن ترکیبات ضد¬قارچی جدید امری اجتناب ناپذیر به نظر می آید. از این رو منابع مختلف تولید کننده آنتی¬بیوتیک مورد غربال¬گری قرار می¬گیرند که از بین آن¬ها باکتری¬ها بویژه باسیلوس¬ها از گزینه¬های مهم برای یافتن آنتی¬بیوتیک و تولید صنعتی آن هستند. گونه¬های مختلف باسیلوس سریع رشد کرده و قادر به تولید متابولیت¬های مختلفی هستند. هدف از ت...
The draft genome sequences of six Bacillus strains, isolated from the International Space Station and belonging to the Bacillus anthracis-B. cereus-B. thuringiensis group, are presented here. These strains were isolated from the Japanese Experiment Module (one strain), U.S. Harmony Node 2 (three strains), and Russian Segment Zvezda Module (two strains).
Bovine Bacillus anthracis isolates from Cameroon were genetically characterized. They showed a strong homogeneity, and they belong, together with strains from Chad, to cluster Aβ, which appears to be predominant in western Africa. However, one strain that belongs to a newly defined clade (D) and cluster (D1) is penicillin resistant and shows certain phenotypes typical of Bacillus cereus.
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...
The first guidance for applicants on how to assess toxigenic potential of species of the genus Bacillus was developed by the then Scientific Committee on Animal Nutrition (SCAN) and published in 2000 with the title Opinion on the Safety of use of Bacillus species in Animal Nutrition (EC, 2000). The SCAN guidance took as its basis the then existing knowledge on the structure and biogenesis of to...
Bacteriocins are proteinaceous antibacterial compounds that exhibit bactericidal activity against species closely related to the producer strain. The aim of this research was to investigate the production of bacteriocin by Bacillus spp. isolated from intestinal bacterial flora of the Caspian Frisian Roach (Rutilus frisii kutum). A bacteriocin produced by the bacterium Bacillus cereus strain RF ...
