Mice of the NCS and NCS-D colonies, bred at the Rockefeller University, harbored in their intestine an endemic strain of slow lactose-fermenting Escherichia coli 081+/-: :H21 serotype. In addition, NCS mice have recently acquired E. coli 0109+/-:K48:H14. Both strains persisted during the period of observation, whereas they were not encountered in the feces of mice from two other colonies. Other coliform strains encountered were more transient in their occurrence. Since strains of E. coli 081+/-: :H21 and 0109+/-:K48:H14 are extremely uncommon in human beings, it seems probable that they possess specificity for the mouse host.
在洛克菲勒大学培育的NCS和NCS - D群体的小鼠,其肠道中存在一种地方性的缓慢乳糖发酵大肠杆菌081+/-: :H21血清型。此外,NCS小鼠最近又感染了大肠杆菌0109+/-:K48:H14。在观察期间,这两种菌株都持续存在,而在其他两个群体的小鼠粪便中未发现它们。所遇到的其他大肠菌群菌株出现的时间更短暂。由于大肠杆菌081+/-: :H21和0109+/-:K48:H14菌株在人类中极为罕见,它们似乎对小鼠宿主具有特异性。
