We report that enteroinvasive Escherichia coli (EIEC) serotypes considered to be nonmotile produce an unusually large (77 kDa) flagellin that is assembled into functional flagellum filaments that allow the bacteria to swim in modified motility agar. The EIEC flagellin showed N-terminal identity to most common enterobacterial flagellins, especially those of the E. coli H7 serotype. These data are important in terms of the epidemiology, evolution, and biology of EIEC.
我们报告称,被认为无运动性的肠侵袭性大肠杆菌(EIEC)血清型产生一种异常大的(77 kDa)鞭毛蛋白,该蛋白组装成功能性鞭毛丝,使细菌能够在改良的运动性琼脂中游动。EIEC鞭毛蛋白在N端与大多数常见肠道细菌鞭毛蛋白具有同一性,尤其是大肠杆菌H7血清型的鞭毛蛋白。这些数据在EIEC的流行病学、进化和生物学方面具有重要意义。
