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.
Bacillus cereus is an important cause of foodborne infectious disease and food poisoning. However, B. cereus has also been used as a probiotic in human medicine and livestock production, with low standards of safety assessment. In this study, we evaluated the safety of 15 commercial probiotic B. cereus preparations from China in terms of mislabeling, toxin production, and transferable antimicro...
background & aim: rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. the objective of this study was to optimize alizarin production in intact plant of r.tinctorum by induction with biotic elicitors. experimental: to increase the synthesis ...
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 ...
