摘要
1991年3月从一只家鼠的回盲部、结肠和直肠分离到一株发酵蕈糖但不发酵蔗糖以及VP反应阴性的克氏那氏菌(YersiniaKristensenii),血清型属O:10,毒力测定包括依钙试验、自凝试验。毒力菌落和毒力质粒均阴性。同年10月至12月,从118只家鼠的直肠,分离到3株VP、山梨糖和肌醇阴性的小肠结肠炎那氏菌(Yersiniaenterocolitica),血清型为O:3,毒力测定阳性。结果表明这3个菌株均属小肠结肠炎那氏菌生物3型VP阴性变异株。这是我国首次成功地从家鼠分离和鉴定克氏那氏菌和小肠结肠炎那氏菌生物3型VP阴性变异株。
In March 1991,a strain of Yersinina Kristensenii serotype O:10 was isolatedfrom the caecum,colon and rectum of a house rat.This isolate fermented trehalose but failed toferment sucrose,and theVoges-proskauer reaction was negative.The isolate was tested for viru-lence characteristics including calcium dependency,autoagglutination,virulence colony and viru-lence plasmid,and all were negative.During the period between October and December 1991,atotaI of 118 samples taken from the rectum of 118 house rats were examined.Three strains ofYersinia entercolitica belonging to serotype O:3 were isolated.The isolates did not fermentsorbose and inositol,and gave a negative Voges-proskauer reaction,The virulence tests werepositive,The results indicate that these three isolates are Yersinia enterocolitica Voges-proskau-er-Negative variants of biotype 3.This is the first successful isolation and identification ofYersinia kristensenii and Yersinia enterocolitica Voges-proskauser-Negative variant of biotype3 from house rats in China。
