近年来,美国东北部地区的肠炎沙门氏菌血清型感染明显增加.为此,作者以病例对照研究调查了一起医院内肠炎沙门氏菌爆发感染的宿主危险因素.随机选择粪便培养证实为沙门氏菌肠炎的75例病人为病例组,80例粪便培养阴性的病人为对照组.病例组平均年龄为68岁(男性占55%),对照组为66岁(男性占49%).上述两组病例均进食过已知被肠炎沙门氏菌污染的色拉.食用低钠色拉者为高度暴露,常规含钠色拉者为低度暴露.调查的宿主危险因素包括饮食和原发性疾病.
In recent years, serotypes of S. Enteritidis serotypes have been significantly increased in the northeastern United States, and as a result, the authors investigated a case-control study of a host of risk factors for hospital-acquired outbreaks of Salmonella enteritidis in 75 patients randomly selected for stool culture as Salmonella enteritidis In the case group, 80 patients with fecal culture negative were control group.The average age of patients in the case group was 68 years (55% in men) and 66 years in control group (49% in men) Salad contaminated with Salmonella enteritidis Low sodium salads are highly exposed and low sodium salads are low exposures The host risk factors investigated include diet and primary disease.
