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.
1967年至1996年间，比利时从患者的各种胃肠道和肠外部位分离出18700多株耶尔森菌（不包括鼠疫耶尔森菌）。比利时的两个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无致病性的血清群和相关菌种。急性小肠结肠炎是小肠结肠炎耶尔森菌感染最常见的临床形式，主要影响5岁以下儿童。自1967年以来，分离株数量逐年稳步增加，1975年有305例，1986年增至1469例。从1987年起，报告病例数明显减少，尽管参与检测的实验室数量和培养技术保持不变。小肠结肠炎耶尔森菌感染发生率的显著下降可能是由于屠宰程序和人群饮食习惯的改变。
