O:15型小肠结肠炎耶氏菌毒力株的发现与鉴定

Isolation and Differentiation of Yersinia Enterovolitica O:15 Virulence Strains from Patient and Pig

从腹泻病人和猪各分离出1株O:15型小肠结肠炎耶氏菌,它们含有毒力质粒(45megadaltons)、VW抗原和Vi抗原,并与毒力因子血清发生凝集反应,在小鼠体内能大量繁殖。这些特征指出:这是两个典型的毒力株,这在该型中是少见的。

Two strains of Yersinia enterocolitica O : 15 were isolated from diarrheal patient and pig. They contain virulent plasmid (45 megadaltons), Vi antigen, and VW antigen, and can be agglutinated by antiserum against virulent factors of Yersinia enterocolitica. These cha-racters comfirmed that the two strains were virulent.
