研究 Enterococcus faecalis 在铁暴露及谷胱甘肽缺乏条件下的代谢与转录响应，发现 Δgsh 突变体通过降低铁含量、激活尿素循环和甘油代谢补偿谷胱甘肽不足，维持生长。基因组模型显示 arginine 代谢（arcoperon）和能量生成途径是关键补偿机制，且转录因子 ArgR 的调控 ...

Acute graft-versus-host disease occurs when donor immune cells attack the recipient's tissues after an allogeneic hematopoietic stem cell transplantation (allo-HCT). Researchers recently identified a ...

Singapore scientists have found a new way to disarm antibiotic-resistant bacteria and speed up chronic wound healing using ...

Researchers found that a common antibiotic-resistant bacterium prevents wounds from healing by chemically paralyzing skin cells rather than attacking them directly. Scientists from an international ...

本研究评估天然产物芦竹黑素（Equisetin）对多重耐药肠球菌的强效抗菌作用，发现其通过破坏膜完整性、诱导蛋白/DNA泄漏、去 ...

A new study finds that two subtypes of pathogenic Escherichia coli (E. coli) produce five to 16 times more protective capsular 'slime' when Enterococcus faecalis (EF) is present. The finding could ...

This type of infection cannot be eliminated by host defense mechanisms, and needs to be treated by chemical–mechanical procedures. 6 Irrigation by chemical solutions should be aimed to eliminate both ...

A new study led by a research team from Massachusetts Eye and Ear and Harvard Medical School describes how bacteria adapted to the modern hospital environment and repeatedly cause antibiotic-resistant ...
