To determine the risk factors for Yersinia enterocolitica (YE) infection in Belgium, which is the country with the highest incidence of this infection, 40 persons with YE infections due to serotype O:3 (n = 36) or O:9 (n = 4) were compared with matched controls. Most patients had acute gastroenteritis; 1 had a liver abscess. 20% were admitted to hospital; the mean duration of hospital stay was 9 days. YE infection was strongly associated with eating raw pork in the 2 weeks before onset (odds ratio = 12, p = 0.00002), a factor that accounted for 58% of the YE infections studied. 14 (18%) of 79 families surveyed at a well-baby clinic fed their children raw pork from a median age of 18 months. Specific control measures to reduce contamination and consumption of raw pork may reduce the incidence of YE infections.
为确定在耶尔森氏菌小肠结肠炎（YE）感染发病率最高的比利时，YE感染的风险因素，将40例由O:3血清型（n = 36）或O:9血清型（n = 4）导致的YE感染患者与匹配的对照组进行了比较。大多数患者患有急性肠胃炎；1例有肝脓肿。20%的患者入院治疗；平均住院时间为9天。YE感染与发病前2周内食用生猪肉密切相关（优势比= 12，p = 0.00002），该因素占所研究的YE感染病例的58%。在一家母婴诊所对79个家庭进行调查，其中14个家庭（18%）从孩子18个月大的中位数年龄起就喂他们吃生猪肉。采取具体的控制措施以减少生猪肉的污染和消费，可能会降低YE感染的发病率。
