Abstract

A series of nearly isogenic O4-12, and O-6,7 Salmonella typhimurium strains differing in regard to the enterobacterial common antigen (ECA) were constructed by conjugation. When tested in intraperitoneal infection of mice, the O-4,12 strains containing ECA were more virulent than their O-4,12 sister recombinants without ECA (P = less than 0.001). The same difference could be shown with ECA-positive and ECA-negative S. typhimurium derivatives, whose O antigens were of the group C type (O-6,7). The ECA-positive and ECA-negative O-4,12 strains did not differ in their growth rates in broth or clearance rates in vivo.

摘要

通过接合构建了一系列在肠杆菌共同抗原(ECA)方面存在差异的近等基因鼠伤寒沙门氏菌O4 - 12和O - 6,7菌株。当在小鼠腹腔感染实验中进行测试时,含有ECA的O - 4,12菌株比其不含ECA的O - 4,12姐妹重组体更具毒力(P<0.001)。对于O抗原为C组类型(O - 6,7)的ECA阳性和ECA阴性鼠伤寒沙门氏菌衍生物,也能显示出同样的差异。ECA阳性和ECA阴性的O - 4,12菌株在肉汤中的生长速率或体内清除率方面没有差异。
