调查了丹麦一家猪场肠沙门氏菌复发感染的流行情况。对同一猪场（1996年及以后收集）经沙门氏菌污染的动物粪便（浆液）和亚临床分离物的粪便分离物的脉冲凝胶电泳图谱进行比较，显示出相同的图谱，表明肠炎沙门氏菌血清型鼠伤寒沙门氏菌DT12克隆在畜群环境中长期存在。此外，当被沙门氏菌污染的泥浆处理在农业土壤上时（一种常见的废物处理做法），病原体在传播后长达14天被分离出来，这表明病原体在环境、动物和人类中传播的潜在高风险。
Prevalence of Salmonella enterica on a Danish pig farm presenting recurrent infections was investigated. A comparison of the pulsed-held gel electrophoresis patterns of fecal isolates from piggeries, waste slurry, and agricultural soil amended with Salmonella-contaminated animal waste (slurry) and subclinical isolates from the same farm (collected in 1996 and later) showed identical patterns, indicating long-term persistence of the Salmonella enterica serovar Typhimurium DT12 clone in the herd environment. Furthermore, when Salmonella-contaminated slurry was disposed of on the agricultural soil (a common waste disposal practice), the pathogen was isolated up to 14 days after the spread, indicating potentially high risks of transmission of the pathogen in the environment, animals, and humans.
