New research shows that a large, ubiquitous mobile genetic element changes the antagonistic weaponry of Bacteroides fragilis, a common bacterium of the human gut. Bacteria evolve rapidly in the ...
Interestingly, in Bacteroides fragilis, DNA inversions turned OFF the production of polysaccharide A, a molecule coating the ...
Rival tribes of bacteria armed with poison darts are fighting it out in your gut, with armies of traitors often winning the day ...
New research from the University of Chicago shows that a large, ubiquitous mobile genetic element changes the antagonistic weaponry of Bacteroides fragilis, a common bacterium of the human gut.
在我们的肠道里，细菌们就像是一群小战士，通过互相分享基因来快速进化。拟杆菌（Bacteroidales）是一类大量存在的肠道细菌，它们可以交换数百种基因。但这些基因转移对细菌或宿主健康的具体影响，我们还知之甚少。最近，芝加哥大学的研究人员发现了一种大 ...
维生素 D 生物利用度的增加会导致微生物组发生有利于脆弱类杆菌（Bacteroides fragilis，这是一种在人体和小鼠中都有的厌氧性革兰氏阴性菌）的变化。
Bacterial vaginosis is confined to an asymptomatic state in at least half of the cases. Symptomatic BV, on the other hand, is most typically accompanied by foul-smelling, profuse vaginal discharge ...
抗生素自面世以来，以其良好的抗菌效果的得到广泛使用，同时也逐渐在治疗后期产生的抗药性。抗生素耐药病原体的广泛流行加剧了治疗感染的挑战，并对人类健康构成威胁。据预测，到2050年，耐药性感染每年可能导致全球1000万人死亡。

Your gut bacteria are at war - and force their enemies to switch sidesIn this bug-shoot-bug world, one of the most vicious is a species called Bacteroides fragilis, which releases a range of ...
New research from the University of Chicago shows that a large, ubiquitous mobile genetic element changes the antagonistic weaponry of Bacteroides fragilis, a common bacterium of the human gut.
Bacteria evolve rapidly in the human gut by sharing genetic elements with each other. Bacteriodales is a prolific order of gut bacteria that trade hundreds of genetic elements. Little is known ...
