Yersinia enterocolitica biotype 1, serotype O:21 was isolated from feces or rectal washings of three members of one family in northwestern Saskatchewan. The three isolates gave positive pathogenicity tests in guinea pigs with cultures grown at 22 degrees C as inoculum. All three cases showed clinical symptoms consistent with yersiniosis. All three cases had symptoms of diarrhea and abdominal pain, and two cases had recorded fever. In two cases, appendicitis was initially suspect. One case with ileitis and peritonitis was fatal. The environmental source of the infection was not found, but river water, milk, and person-to-person spread are discussed as possible sources of the infections. The need for microbiology laboratories to culture stool specimens specifically for Y. enterocolitica, using cold-enrichment techniques is emphasized. This family outbreak of yersiniosis provides further evidence that certain biotype 1 strains of Y. enterocolitica are pathogenic.
小肠结肠炎耶尔森菌生物1型，血清型O:21，从萨斯喀彻温省西北部一个家庭的三名成员的粪便或直肠冲洗物中分离得到。这三株分离菌在以22摄氏度培养的豚鼠培养物作为接种物时，致病性试验呈阳性。所有三例均表现出与耶尔森菌病一致的临床症状。所有三例均有腹泻和腹痛症状，两例有发热记录。最初有两例怀疑为阑尾炎。一例患回肠炎和腹膜炎，死亡。未发现感染的环境来源，但讨论了河水、牛奶和人传人作为可能的感染源。强调微生物学实验室需要使用冷增菌技术专门培养粪便标本以检测小肠结肠炎耶尔森菌。这次家庭爆发的耶尔森菌病进一步证明了某些小肠结肠炎耶尔森菌生物1型菌株具有致病性。
