目的了解新疆维吾尔自治区部分地区不同年龄段的健康人群军团菌感染状况。方法2005年4月～5月对297名健康体检人群进行血清嗜肺军团菌1型(Lp1)、3型(Lp3)和6型(Lp6)抗体水平调查。结果血清嗜肺军团菌三种抗体均有阳性检出、阳性率为26.60%(79/297),其中Lp3型阳性率最高15.82%(47/297),其次为Lp6型11.11%(33/297)和Lp1型7.07%(21/297),同时感染2种血清型者占5.05%(15/297)、同时感染3种血清型者占1.01%(3/297)。健康体检人群主要为两个民族,其中维吾尔族占56.90%(169/297),汉族占43.10%(128/297),汉族阳性率占15.49%(46/297),维吾尔族阳性率占11.11%(33/297),两者差异有统计学意义(P<0.01)。结论新疆健康人群普遍存在一定程度的嗜肺军团菌感染。
Objective To understand the status of Legionella infection in healthy population of different ages in some areas of Xinjiang Uygur Autonomous Region. Methods The levels of Lp1, Lp3 and Lp6 antibodies in 297 healthy volunteers from April 2005 to May 2005 were investigated. Results The positive rate of the three antibodies against Legionella pneumophila was 26.60% (79/297). The positive rate of Lp3 was 15.82% (47/297), followed by that of Lp6 (11.11%, 33/297 ) And 7.07% (21/297) of Lp1 type, 5.05% (15/297) with two serotypes, and 1.01% (3/297) with three serotypes. The majority of health examination population are two ethnic groups, of which 56.90% (169/297) are Uyghur, 43.10% (128/297) are Han nationality, 15.49% (46/297) are Han nationality, 11.11% are Uighur nationality, (33/297), the difference was statistically significant (P <0.01). Conclusion The prevalence of Legionella pneumophila infection is common in healthy population in Xinjiang.
