A foodborne outbreak of Salmonella enteritidis PT4 is described. This microrganism was detected in a home-made dessert, in the duck and hen eggs used for its preparation and in faecal samples of six persons involved in the outbreak. PCR ribotyping revealed that all the strains shared a profile of S. enteritidis never previously identified in southern Italy and quite different from that of the strains simultaneously isolated in the same geographic area. The possible identification of a clonal variant of S. enteritidis PT4 host-adapted to duck is hypothesized.
本文描述了一起由肠炎沙门氏菌PT4引起的食源性疾病暴发。在一种自制甜点、用于制作该甜点的鸭蛋和鸡蛋以及6名疫情相关人员的粪便样本中检测到了这种微生物。PCR核糖体分型显示，所有菌株均具有一种肠炎沙门氏菌的图谱，该图谱在意大利南部从未被鉴定过，且与同一地理区域同时分离出的菌株图谱有很大不同。推测可能鉴定出了一种适应鸭宿主的肠炎沙门氏菌PT4克隆变体。
