Objective To realize the contamination status and etiological characteristics of Legionella pneumophila in public places in Shiyan City from 2017-2020,provide targeted measures for the prevention and control of legionnaire disease. Methods The shower water,condensed water and cooling water collected from public places in Shiyan City during 2017-2020 were detected for Legionella pneumophila. The isolates of Legionella pneumophila were classified by serotyping and pulsed field gel electrophoresis(PFGE). Results A total of 517 samples were collected and tested,and the detection rate of Legionella pneumophila was 7.54%.The detection rate of Legionella pneumophila in hotels was the highest(28.79%),and there was statistically significant difference in the detection rate among different places(P0.01). The detection rate of shower water,condensate water and cooling water was4.41%,12.50% and 27.42%,respectively,and the difference was statistically significant (χ~2=42.04,P0.01). The 41 isolates of Legionella pneumophila were divided into five serotypes,furthermore,LP1 was the dominant serotype(53.66%). The 41 isolates produced 19 types of PFGE with similarity between 43%-100%,indicating a local genetic diversity. Conclusion The contamination status of Legionella pneumophila in public places in Shiyan City from 2017-2020 can not be ignored,and it is necessary to strengthen the health supervision and monitoring according to the contamination status and etiological characteristics of Legionella pneumophila in public places in Shiyan City.
