1967 年至 1996 年间，比利时从患者的各种胃肠道和肠外部位回收了超过 18,700 株耶尔森氏菌（不包括鼠疫耶尔森氏菌），两个比利时参考实验室进行了全面鉴定和血清分型。小肠结肠炎耶尔森氏菌 O:3 血清群占主导地位（占菌株的 79.4%），其次是 O:9 血清群（11.1%）。其余 9.5% 的分离株属于通常被认为是非致病性的血清群和相关物种。急性小肠结肠炎是 Y 小肠结肠炎感染最常见的临床形式，主要影响 5 岁以下的儿童。自1967年以来，隔离病例每年都在稳步增加，1975年有305例，1986年达到1,469例。从1987年起，尽管参与的实验室和培养技术数量保持不变，但报告病例数明显减少。小肠结肠炎耶尔森氏菌感染发生率的显着下降可能是由于屠宰程序和人群饮食习惯的变化所致。
Between 1967 and 1996, > 18,700 strains of Yersinia species, excluding Yersinia pestis, were recovered in Belgium from a variety of gastrointestinal and extraintestinal sites in patients, Full identification and serotyping were performed by the two Belgian reference laboratories. Yersinia enterocolitica serogroup O:3 predominated (79.4% of strains), followed by serogroup O:9 (11.1%). The remaining 9.5% of isolates belonged to serogroups and related species generally considered nonpathogenic, Acute enterocolitis was the most common clinical form of Y, enterocolitica infection, affecting primarily children younger than 5 years of age. Since 1967, there was a steady increase in isolations every year, with 305 cases in 1975 and up to 1,469 in 1986. From 1987 on, there was a clear decrease in the number of reported cases, although the number of participating laboratories and culture techniques remained constant. This significant decrease in the occurrence of Y. enterocolitica infections may be explained by changes in the slaughtering procedures and eating habits of the population.
