A combination of typing methods was used to identify the strains and the infection source in a food-borne outbreak of Salmonella enterica occurring in a summer camp and affecting 25 children. All isolates tested were found to be serovar Enteritidis, with an identical biotype API 20E and ribotype. However, they differed in their plasmid profiles and/or antibiograms, and were grouped into three strains. One strain was found in human stools, another in a hen's egg, and the third in both stools and another egg pointing to large Spanish omelettes to be the contaminated food source.
采用多种分型方法对一个夏令营发生的一起沙门氏菌食源性暴发进行菌株和感染源鉴定，该暴发影响了25名儿童。所有检测的分离株均为肠炎血清型，具有相同的API 20E生物型和核糖体分型。然而，它们的质粒图谱和/或抗菌谱不同，被分为三个菌株。在人类粪便中发现了一个菌株，在一枚鸡蛋中发现了另一个菌株，在粪便和另一枚鸡蛋中均发现了第三个菌株，这表明大份西班牙煎蛋饼是受污染的食物来源。
