本研究针对家蚕微粒子病（Pebrine）防治难题，揭示了肠道共生菌Enterococcus faecalis LX10通过分泌肠球菌素（EntLX）抑制Nosema bombycis（N. bombycis）感染的分子机制。研究发现EntLX依赖凝胶酶（GelE）加工和二硫键形成蛋白（DsbA）激活，能显著降低细胞感染率并修复肠道 ...

抗生物膜活性及抗菌机制研究。 近年来，耐药性细菌的感染问题日益严峻，其中以凝固酶阴性葡萄球菌（*Staphylococcus epidermidis*）和肠球菌（*Enterococcus faecalis*）为代表的生物膜相关病原体，因其形成的稳定生物膜结构可显著增强抗生素耐受性，成为医院感染防控 ...

Enterococcus faecalis is a species of bacteria that is naturally found in the intestines. While it tends to be harmless in that environment, it has the potential to cause a serious infection if it ...

2019年4月15日 讯 /生物谷BIOON/ --近日，一篇发表在国际杂志Science Translational Medicine上的研究报告中，来自美国多家研究机构的科学家们通过研究阐明了一种常见的人类肠道细菌如何通过进化的方式转变成为致死性的病原体，文章中，研究者描述了粪肠球菌 ...

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 ...

Microbial symbioses likely drive the evolution of diet within animals, yet these symbiotic relationships remain poorly understood for many organisms. The bacterial endosymbiont Enterococcus faecalis ...

A new study describes how bacteria adapted to the modern hospital environment and repeatedly cause antibiotic-resistant bloodstream infections. This study examined one of the first sustained hospital ...

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 ...

For three decades, the deadly bacteria sat in cold storage. Normally, Enterococcus faecalis lives harmlessly in the human gut. One particular strain, however, caused a series of strangely persistent ...
