An increase in the number of human isolates of Salmonella virchow phage type (PT) 26 in England and Wales during 1994 was investigated. A national case control study was conducted which included 88 cases and 182 controls. The cases were mostly young adults (median age 26) and 13 (15%) were admitted to hospital. Acquisition of S. virchow PT 26 was associated with the consumption of any chicken (OR 2.5, CI 1.1-5.8), of chicken curry from restaurants and take aways (OR 2.9, CI 1.4-6.1), and of some other diverse types of pre-prepared chicken (OR 3.8, CI 1.9-7.6). Halal chicken was associated (P = 0.006) with illness in a subset. There were negative associations with contact with animals (OR 0.47, CI 0.23-0.95) and with the consumption of chicken cooked whole (OR 0.37, CI 0.21-0.66). The increase in S. virchow PT 26 may be due to changing epizoology and may be an indicator of what will become the dominant salmonella strain in poultry in future years. The increasing incidence of S. virchow PT 26 is of particular concern because of its association with more invasive disease in humans.
对1994年英格兰和威尔士甲型副伤寒沙门氏菌噬菌体分型（PT）26型人类分离株数量的增加情况进行了调查。开展了一项全国性病例对照研究，包括88例病例和182名对照。病例大多为年轻人（中位年龄26岁），13例（15%）入院治疗。感染甲型副伤寒沙门氏菌PT 26型与食用任何鸡肉（比值比2.5，可信区间1.1 - 5.8）、食用餐厅和外卖的咖喱鸡（比值比2.9，可信区间1.4 - 6.1）以及其他一些种类的预制鸡肉（比值比3.8，可信区间1.9 - 7.6）有关。在一个亚组中，清真鸡肉与发病有关（P = 0.006）。与接触动物（比值比0.47，可信区间0.23 - 0.95）和食用整只烹制的鸡肉（比值比0.37，可信区间0.21 - 0.66）呈负相关。甲型副伤寒沙门氏菌PT 26型数量的增加可能是由于流行病学变化，可能预示着未来几年家禽中哪种沙门氏菌菌株将成为优势菌株。甲型副伤寒沙门氏菌PT 26型发病率的上升尤其令人担忧，因为它与人类更具侵袭性的疾病有关。
