英国肯特郡今年3月暴发侵袭性脑膜炎球菌病疫情,21人感染,其中9人需重症监护。牛津大学马丁·梅登团队对6名患者的细菌全基因组测序发现,肯特菌株从无害细菌中获取了多个基因,使其能更好地躲避免疫系统并从血液中摄取铁,从而迅速增殖。研究者认为,这些发现有助于开发更有针对性的疫苗,但无法预测下一株高侵袭性菌株。
原文开头
The bacterium behind 21 cases of meningitis in southern England in March became a “super powerful bug” after taking genes from other microbes, finds Carissa Wong A SEVERE outbreak of invasive meningococcal disease, which can cause meningitis and sepsis, in Kent in the UK earlier this year was driven by a bacterial strain that took genes from harmless microbes. This helped the resulting bacteria evade the immune system and obtain iron from blood, boosting their growth. “What was really unusual about the outbreak is quite how explosive it was,” says Emma Wall at Queen Mary University of London, who wasn’t involved in the discovery. …
