A total of 184 strains of S. Enteritidis isolated from patients with sporadic cases of diarrhea during the period from April 1985 to March 1991 in Yamanashi Prefecture, were examined for their drug susceptibility, phage typing and plasmid profile. The results can be summarized as follows: 1) In 1989, cases of sporadic diarrhea due to S. Enteritidis has drastically increased twenty-eight-fold from 4 to 112 cases. 2) The most predominant ages of S. Enteritidis isolates were that of 2 years age. 3) The predominant phage type (PT), accounting for almost 71% of the strains isolated, was PT 34 in 1989. 4) Eighty-two (73.2%) out of 112 strains of S. Enteritidis were resistant to SM single in 1989. In 1990, SM single resistant strains were 49 (90.7%) out of 54 strains of S. Enteritidis. 5) The predominant plasmid profile of S. Enteritidis isolates were 60, 55 Kbp plasmids. 6) In 1989, the characteristic of S. Enteritidis isolated from the cases of sporadic diarrhea were resistant to SM single, identified as belonging to PT 34 or PT 4. Almost S. Enteritidis strains of PT 34 carrying 60, 55 Kbp plasmids and many strains of PT 4 S. Enteritidis possessed only 60 Kbp plasmid.
对1985年4月至1991年3月期间从山梨县散发性腹泻患者中分离出的184株肠炎沙门氏菌进行了药敏试验、噬菌体分型和质粒图谱分析。结果总结如下：1）1989年，肠炎沙门氏菌引起的散发性腹泻病例从4例急剧增加到112例，增加了28倍。2）肠炎沙门氏菌分离株最主要的年龄是2岁。3）1989年，最主要的噬菌体类型（PT）是PT 34，占分离菌株的近71%。4）1989年，112株肠炎沙门氏菌中有82株（73.2%）对链霉素单一耐药。1990年，54株肠炎沙门氏菌中有49株（90.7%）对链霉素单一耐药。5）肠炎沙门氏菌分离株的主要质粒图谱是60、55千碱基对的质粒。6）1989年，从散发性腹泻病例中分离出的肠炎沙门氏菌的特征是对链霉素单一耐药，鉴定为属于PT 34或PT 4。几乎所有携带60、55千碱基对质粒的PT 34肠炎沙门氏菌菌株和许多PT 4肠炎沙门氏菌菌株仅拥有60千碱基对的质粒。
