In Ontario, Canada's most populous province with more than 14 million residents, we have recently linked microbiology test results to healthcare administrative datasets,[2]such that it is now possible to study the relative risk of death amo...
或单独直接降解进入E.coli细胞中的具有游离DSE的外源DNA(如λ或T4噬菌体DNA);用于CRISPR记忆的间隔序列的产生也依赖于RecBCD对主要通过复制叉解体形成的DSE的处理(由于Chi序列在E.coli染色体而非外源DNA中大量存在,且在外源DNA[高拷贝外源质粒和噬菌体DNA]上存在更多复制叉,所以用于CRISPR记忆的间隔序列主要来自外源DNA...
E. coliinfections aren't typically treated with antibiotics unless the infection is outside the intestinal tract, such as with a UTI. Within the intestinal tract, though, "antibiotics may kill other beneficial bacteria in the gut, allowing more space and nutrients for theE. colito grow," said...
(σ32)是E.coli拥有的七个转录调控因子之一,可在E.coli细胞受到热击、高渗、氧化、干燥、抗生素等环境压力时通过诱导热休克反应提高细胞的生存能力和适合度。因此,与RpoS一样,RpoH也是一个一般压力反应调控因子。RpoH具有广泛的调控作用,可在温度升高时控制数百个基因的转录,这些基因编码的功能涉及蛋白质稳态维持、...
The finding could lead to the development of beta-blockers as a therapy to impede this cellular signaling system, causing the harmful bacteria to pass blindly through the digestive tract, according to Vanessa Sperandio, assistant professor of microbiology."You're not really attacking the bacteria ...
Aims: E. coli is a widely known model organism for life science research, especially in modern bio-engineering and industrial microbiology. The goal of our current study is to understand the growth inhibitory mechanism of biosynthesized CdS nanoparticles on E. coli bacteria. Main methods: ...

In the image below Escherichia coli can be seen growing on MacConkey agar. Escherichia coli culture on MacConkey agar. View Media Gallery Definitive diagnosis is based on the isolation of the organism in the microbiology laboratory from clinical specimens. Specimens may be blood, urine, sputum, ...
Is there an infant mortality in bacteria? It is based on the selection of stained cells through flow cytometry and the derivation of their ages at death from their sizes. If an infant mortality effect can be identified in E. coli it can be conjectured that a similar ... EM Garcia-Roger...
摘要:PolⅣ和PolV作为E.coli中的Y家族DNA聚合酶,分别由dinB和umuDC基因编码。由于其特殊结构,PolⅣ和PolV可对带有非编码损伤的DNA进行移损合成。移损合成作为一种损伤耐受机制,可在DNA损伤暂时未被修复的情况…
