From July 1976 to May 1977, 270 rats (259 Rattus norvegicus and R. rattus) in Sapporo were examined for the presence of Yersinia enterocolitica in house rats. The organism was isolated in 55 rats (54 R. norvegicus and 1 R. rattus). Isolated strains were determined as O group (O)3, biovar 4; O4, biovar 1; O5A, biovar 1; and O6, biovar 1. The isolation of O3, biovar 4 strains from R. norvegicus is the first in the world, as far as we know. The organism was isolated from the duodenum in 3 rats, the jejunum in 7 rats, the ileum in 8 rats, the cecum in 34 rats, the colon in 23 rats, the rectum in 16 rats, and the mesenteric lymph nodes in 5 rats. The organism was not isolated from liver, spleen, and kidneys. Isolation of the organism from the mesenteric lymph nodes was made in 1 out of 2 O3-positive rats, 1 out of 7 O5A-positive ones, and 3 out of 29 O6-positive ones. A high agglutinin titer was recorded in the two O3-positive rats and in one O6-positive animal.
1976年7月至1977年5月，对札幌市的270只大鼠（259只褐家鼠和黑家鼠）进行检查，以确定家鼠体内是否存在小肠结肠炎耶尔森氏菌。在55只大鼠（54只褐家鼠和1只黑家鼠）中分离出了该菌。分离出的菌株被鉴定为O群（O）3，生物变种4；O4，生物变种1；O5A，生物变种1；以及O6，生物变种1。据我们所知，从褐家鼠中分离出O3，生物变种4菌株在世界上尚属首次。该菌在3只大鼠的十二指肠、7只大鼠的空肠、8只大鼠的回肠、34只大鼠的盲肠、23只大鼠的结肠、16只大鼠的直肠以及5只大鼠的肠系膜淋巴结中被分离出来。在肝脏、脾脏和肾脏中未分离出该菌。在2只O3阳性大鼠中有1只、7只O5A阳性大鼠中有1只以及29只O6阳性大鼠中有3只从肠系膜淋巴结中分离出了该菌。在2只O3阳性大鼠和1只O6阳性动物中记录到了高凝集素滴度。
