We investigated the clonal relationships among 63 Escherichia coli strains of antigen serogroup O78 isolated from infections in humans, cattle, sheep, pigs, and chickens. Both septicemic and enterotoxigenic isolates were included in the study. A main group of 55 E. coli strains consisting of 52 septicemic isolates and 3 human enterotoxigenic E. coli isolates were clustered in related clones. The remaining eight strains, four human and four animal isolates, were clonally heterogeneous. The main group of 55 clonally related strains included isolates from human and animal infections. This result indicates that animals are a possible source of serogroup O78 septicemic E. coli infections in humans.
我们研究了从人类、牛、羊、猪和鸡的感染中分离出的63株O78抗原血清群大肠杆菌菌株之间的克隆关系。该研究包括败血症型和产肠毒素型分离株。由52株败血症型分离株和3株人类产肠毒素型大肠杆菌分离株组成的55株大肠杆菌菌株的主要群体聚集在相关克隆中。其余8株菌株，4株人类分离株和4株动物分离株，在克隆上是异质的。55株克隆相关菌株的主要群体包括来自人类和动物感染的分离株。这一结果表明，动物是人类O78血清群败血症型大肠杆菌感染的可能来源。
