Environmental Persistence of Bacillus anthracis and Bacillus subtilis Spores
There is a lack of data for how the viability of biological agents may degrade over time in different environments. In this study, experiments were conducted to determine the persistence of Bacillus anthracis and Bacillus subtilis spores on outdoor materials with and without exposure to simulated sunlight, using ultraviolet (UV)-A/B radiation. Spores were inoculated onto glass, wood, concrete, ...
متن کاملکلونکردن ژن آنتی‌ژن ایمنی‌بخشBacillus anthracis در Bacillus subtilis
سابقه و هدف: آنتی‌ژن ایمنی‌بخش(PA) (Protective antigen) Bacillus anthracis به‌عنوان واکسن سیاه زخم مورد استفاده قرار می‌گیرد. کلون و بیان ژن PA در سویه‌های مختلف گزارش شده است که بیش‌ترین بیان، در B. subtilis تا μg/ml 160 بوده است. هدف از این تحقیق کلون کردن ژن PA در ناقل بیان‌کننده pWB980 و انتقال آن به B. subtilis سویه WB600 می‌باشد. مواد و روش‌ها: در این مطالعه پلاسمید pXO1 از...
متن کاملMethionine regeneration and aminotransferases in Bacillus subtilis, Bacillus cereus, and Bacillus anthracis.
The conversion of ketomethiobutyrate to methionine has been previously examined in a number of organisms, wherein the aminotransferases responsible for the reaction have been found to be members of the Ia subfamily (L. C. Berger, J. Wilson, P. Wood, and B. J. Berger, J. Bacteriol. 183:4421-4434, 2001). The genome of Bacillus subtilis has been found to contain no subfamily Ia aminotransferase se...
متن کاملOligochlorophens are potent inhibitors of Bacillus anthracis.
Bacterial cytoskeletal proteins are an emerging set of targets for antibiotic development. This paper describes oligochlorophen analogs based on the monomer 4-chloro-2,6-dimethylphenol as antimicrobial agents against Bacillus anthracis. The most potent analogs have a MIC of 160 to 320 nM against B. anthracis and may target the cytoskeletal protein FtsZ. B. anthracis develops resistance to the o...
متن کاملHtrC is involved in proteolysis of YpeB during germination of Bacillus anthracis and Bacillus subtilis spores.
Bacterial endospores can remain dormant for decades yet can respond to nutrients, germinate, and resume growth within minutes. An essential step in the germination process is degradation of the spore cortex peptidoglycan wall, and the SleB protein in Bacillus species plays a key role in this process. Stable incorporation of SleB into the spore requires the YpeB protein, and some evidence sugges...
