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 ...

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 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 ...

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.

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.

Named lipopolysaccharide (LPS) and sourced from the Gram-negative bacteria Bacteroides fragilis found in our gastrointestinal (GI) tract, the specific neurotoxin in question is identified as BF-LPS.
