Representative strains of the Bacillus cereus group of bacteria, including Bacillus anthracis (11 isolates), B. cereus (38 isolates), Bacillus mycoides (1 isolate), Bacillus thuringiensis (53 isolates from 17 serovars), and Bacillus weihenstephanensis (2 isolates) were assigned to 59 sequence types (STs) derived from the nucleotide sequences of seven alleles, glpF, gmk, ilvD, pta, pur, pycA, an...
Antibacterial activities of zinc oxide nanoparticles against two toxigenic bacteria isolated from Egyptian food (Bacillus cereus and Staphylococcus aureus) were investigated in this study. Fifteen samples of five types of sandwiches (Falafel with salad, falafel without salad, bean, sausage and beef luncheon) were purchased from El-Mahla El-Kobra restaurants Tanta, Egypt and investigated for som...
All 47 food-borne isolates of Bacillus cereus sensu stricto, as well as 10 of 12 food-borne, enterotoxigenic isolates of Bacillus thuringiensis, possessed appendages. Spores were moderately to highly hydrophobic, and each had a net negative charge. These characteristics indicate that spores of food-associated B. thuringiensis and not only B. cereus sensu stricto have high potential to adhere to...
Genetic differentiation between sympatric populations of Bacillus cereus and Bacillus thuringiensis.
Little is known about genetic exchanges in natural populations of bacteria of the spore-forming Bacillus cereus group, because no population genetics studies have been performed with local sympatric populations. We isolated strains of Bacillus thuringiensis and B. cereus from small samples of soil collected at the same time from two separate geographical sites, one within the forest and the oth...
BACKGROUND Kawasaki disease (KD) is a systemic vasculitis of unknown etiology. The innate immune system is involved in its pathophysiology at the acute phase. We have recently established a novel murine model of KD coronary arteritis by oral administration of a synthetic microbe-associated molecular pattern (MAMP). On the hypothesis that specific MAMPs exist in KD sera, we have searched them to...
جهت کنترل بیولوژیکی بیماری پژمردگی آوندی میخک، ناشی از قارچ fusarium oxysporum f.sp . dianthi، اثر آنتاگونیستی 141 باکتری جدا شده از فراریشه (ریزوسفر) میخک علیه قارچ بیمارگر به روش کشت متقابل مورد بررسی قرار گرفت. از این تعداد، 16 استرین دارای خاصیت آنتاگونیستی بودند که 7 استرین با بیشترین هاله بازدارندگی برای آزمون های بعدی انتخاب شدند. بر اساس آزمون های بیوشیمیایی، فیزیولوژیکی و مرفولوژیکی اس...
Background and Objective: Bacillus cereus is responsible for several outbreaks of foodborne diseases. Therefore, the purpose of the study was to replace routine culture testing, by employing PCR directly from food to detect the bacteria and its enterotoxins. Methods: In the present study, a total of 75 Kibda sandwiches, Sausage sandwiches, Luncheon chicken, Luncheon meat and shawarma sandwiche...
Bacillus cereus is a foodborne pathogen causing emetic and diarrheal-type syndromes. Here, we report the whole-genome sequences of 11 B. cereus food isolates.
Three bacterial isolates from the activated sludge of a distillery wastewater treatment plant identified as Xanthomonas fragariae, Bacillus megaterium and Bacillus cereus were found to remove COD and colour from anaerobically digested distillery wastewater in the range of 55 to 68% and 38 to 58% respectively.
