The serotype distributions of Escherichia coli isolated from animal faeces, human faeces and from meat have been compared. There were marked differences in serotype distribution in strains from man and animals. The meat strains generally resembled animal strains. The results suggest either that animal strains of E. coli are not reaching the general human population outside hospital to any great extent, or, if they do so, are failing to implant in the bowel.
对从动物粪便、人类粪便以及肉类中分离出的大肠杆菌血清型分布进行了比较。来自人和动物的菌株在血清型分布上存在显著差异。肉类中的菌株通常与动物菌株相似。结果表明,要么大肠杆菌的动物菌株在很大程度上没有传播到医院以外的普通人群中,要么即便传播到了,也无法在肠道中定植。
