研究团队还发现，来自癌组织的咽峡炎链球菌菌株通过产生甲硫氨酸促进胃癌。进一步观察显示，在癌症粪便宏基因组中 metE 基因的丰度和普遍性较高。研究团队进一步构建了敲除 metE 基因的咽峡炎链球菌突变株（S.anginosusΔmetE），证实了 ...

研究者根据宏基因组数据重建了功能谱，发现胃癌患者中有百余条显著富集的通路，其中值得关注的包括涉及腺苷钴胺素、放线硫醇和尿素衍生物的生物合成，以及儿茶酚和甲苯降解的通路，与肠菌代谢有关。

近日，上海交通大学医学院附属仁济医院房静远院士团队联合深圳华大基因股份有限公司在消化领域著名学术期刊GUT（IF：26.2）上在线发表了题为“Streptococcus anginosus-derived methionine promotes ...

Streptococcus agalactiae (Group B Streptococcus, GBS) is a Gram-positive bacterium, which colonizes the vaginal tract in 10–30% of women. Colonization is transient in nature, and little is known about ...

生物通报道：血链球菌（Streptococcus sanguinis）是形成牙菌斑的多种微生物之一，通常对人体无害，但进入血液（很可能通过口腔微小伤口）后有可能引起细菌性心内膜炎（有致死性）。弗吉尼亚州立大学(Virginia Commonwealth University)研究人员最近完成了S.sanguinis基因 ...

A recent study published in the medical journal Gut has revealed a novel cancer-promoting mechanism of Streptococcus ...

A bacterial pathogen that causes strep throat and other illnesses cloaks itself in fragments of red blood cells to evade detection by the host immune system, according to a study publishing December 3 ...

Researchers have found a further reason for the severity of dual infection by influenza and Streptococcus pneumonia -- a new virulence mechanism for a surface protein on the pneumonia-causing bacteria ...

A concerning increase in global rates of severe invasive infections becoming resistant to key antibiotics has a team of infectious disease researchers studying a recently emerged strain of bacteria ...

Researchers at the University of California (CA, USA) have uncovered a mechanism that allows Group A Streptococcus (GAS) to avoid immune detection, enhancing bacterial virulence and decreasing ...
