ApoFnr binds as a monomer to promoters regulating the expression of enterotoxin genes of Bacillus cereus.
Bacillus cereus Fnr is a member of the Crp/Fnr (cyclic AMP-binding protein/fumarate nitrate reduction regulatory protein) family of helix-turn-helix transcriptional regulators. It is essential for the expression of hbl and nhe enterotoxin genes independently of the oxygen tension in the environment. We studied aerobic Fnr binding to target sites in promoters regulating the expression of enterot...
متن کاملDetection and expression of enterotoxin genes in endophytic strains of Bacillus cereus.
AIMS The aim of this study was to determine whether endophytic Bacillus cereus isolates from agronomic crops possessed genes for the nonhaemolytic enterotoxin (Nhe) and haemolysin BL (HBL) and, therefore, have the potential to cause diarrhoeal illness in humans. METHODS AND RESULTS PCR followed by sequencing confirmed the presence of enterotoxin genes nheA, nheB, nheC, hblA, hblC, hblD in...
متن کاملهمسانهسازی و بیان ژنهای ممزوجی دومن - a1 آنتیژن حفاظتی با سیلوس آنتراسیس و زیرواحد B سم شیگلا در باکتری E. coli
Introduction: Shigella enterotoxin(STxB) is one of the major virulent factors in Shigella dysenteriae type 1 and E. coli O157:H7, which its immunogenicity, adjuvant and delivery characteristic have been proven. Anthrax is a common disease in humans and animals and identifies domain a-1 antibodies of protective antigen(PA) which is 62% of the PA antigens of Bacillus anthracis. Therefore, the pur...
متن کاملPutative virulence factor expression by clinical and food isolates of Bacillus spp. after growth in reconstituted infant milk formulae.
Forty-seven strains representing 14 different Bacillus species isolated from clinical and food samples were grown in reconstituted infant milk formulae (IMF) and subsequently assessed for adherence to, invasion of, and cytotoxicity toward HEp-2 and Caco-2 cells. Cell-free supernatant fluids from 38 strains (81%) were shown to be cytotoxic, 43 strains (91%) adhered to the test cell lines, and 23...
