摘要
1987年4～10月在全国铁路人群中进行了一次军团菌感染血清流行病学调查。按统一方案整群抽查14个地区饮服职工3088人,并选择齐齐哈尔、衡阳、成都三地深入调查不同职业人群2917人。五种(12型)军团菌抗体阳性率0.22～23.81％。调查获得大量数据和资料揭示了我国铁路人群军团菌感染的许多基本特征,如地区差别、菌种(型)分布、年龄特点、职业分布差异、大量隐性感染、正常滴度上限等。为我国制定军团病防制策略,提供了较系统而全面的基础背景材料。
A nationalwide seroepidemiological survey on 5 species (12 serogroups) legionella infections on the railway population in China was carried out from April to October, 1987. According to the unified plan of research, a tatal
of 5494 healthy persons who covered all ages, sexes, and 9different occupations in railway people sampled from 14 various configurational areas in 13 provinces were investigated. The antibodies to L.pneumophila serogroups 1-8
(Lpl-8) , L. bozemanii (Lb) , L. micdadei (Lm) , L. dumoffii (Ld) and L. gormanii (Lg) were detected by microagglutination test. The results suggest the potential infections with 5species(6-12 serogroups) may be existing among the populations in the areas above mentioned. The positive rate in antibodies to Ld was the highest, to Lp 3 ,6, Lm and Lg the next, and to Lp 2, 4, 7, 8 the lowest. The antibody levels in train-man and railway maintance workers were the highest, whereas in cooks, waiters, pupils and nurses the lowest. The pattern of age-specific prevalence and the geographically-uneven distribution were observed. In addition, a brief suggestion on the ULNT of the 12 Jegio-nella suitable for China was made
