This study aimed at gaining information on the presence of Salmonella in UK turkey hatcheries and possible epidemiological links between breeding farms, hatcheries and finishing farms. The presence of ciprofloxacin-resistant E. coli in hatchery samples, as well as in faecal samples from farms, and trends in occurrence of resistance were also investigated. Over a 2 year-period, four British turkey hatcheries were visited and intensively sampled for the presence of Salmonella and ciprofloxacin-resistant E. coli. In two hatcheries, a link could be demonstrated between the presence of certain Salmonella serovars in the hatcheries and on breeding and finishing farms. Within the hatcheries, serovars linked to breeding farms were found more frequently in the poult processing and dispatch areas, whereas serovars identified as 'resident hatchery contaminants' were predominantly found inside the hatcher cabinets. Ciprofloxacin-resistant isolates of S. Senftenberg were identified in one hatchery, which coincided with enrofloxacin treatment of some of the breeding flocks. Ciprofloxacin-resistant E. coli was found in two hatcheries, and the majority of these isolates showed multidrug resistance.
本研究旨在获取英国火鸡孵化场中沙门氏菌存在的信息，以及种鸡场、孵化场和育肥场之间可能存在的流行病学联系。本研究还调查了孵化场样本和农场粪便样本中存在的环丙沙星耐药大肠杆菌，以及耐药性的发生趋势。在两年的时间里，对四家英国火鸡孵化场进行了深入采样，以检测沙门氏菌和环丙沙星耐药大肠杆菌的存在。在两家孵化场中，发现孵化场和种鸡场中存在的某些沙门氏菌血清型之间存在联系。在孵化场内，与种鸡场有关的血清型更频繁地出现在雏鸡加工和发货区域，而被鉴定为“孵化场固有污染物”的血清型则主要出现在孵化器内部。在一家孵化场中发现了环丙沙星耐药的森夫滕贝格沙门氏菌分离株，这与一些种鸡群的恩诺沙星治疗相吻合。在两家孵化场中发现了环丙沙星耐药的大肠杆菌，其中大多数分离株表现出多药耐药性。
