为了解太原地区军团菌感染的菌型分布特点及优势种型，作者用ＥＬＩＳＡ法分别对太原市三城区、一郊区的部分人群进行了９种１５型军团菌ＩｇＧ抗体的检测，结果军团菌各种型均有阳性出现，所调查的人群以嗜肺军团菌感染为主，Ｌｐ１尤著，非嗜肺军团菌抗体阳性率较低，其中Ｌａ感染者较多。优势种型城区与城区间及城区与郊区间有所不同，嗜肺军团菌在城区的感染菌型主要是Ｌｐ１，郊区则是Ｌｐ４；非嗜肺军团菌在南城、北城及河西区分别以Ｌｊ、Ｌｇ及Ｌａ抗体阳性率为高，而郊区Ｌａ、Ｌｂ抗体阳性率稍高，未见Ｌｊ感染者 In order to understand the distribution characteristics and dominant species of Legionella infection in Taiyuan, the authors used ELISA to detect nine kinds of Legionella IgG antibodies to some populations in three cities and suburbs of Taiyuan. The results showed that Legionella Lactobacillus Legionella infection, Lp1 especially, non-Legionella pneumophila antibody positive rate is low, La infection more. The dominant species of urban and urban areas and between urban and suburban areas are different, Legionella pneumophila infection in urban areas is mainly Lp1, suburbs is Lp4; non-Legionella pneumophila in South City, North City and Hexi District, respectively, Lj , Lg and La antibody positive rate is high, while the suburbs La, Lb antibody positive rate is slightly higher, no Lj infection
