【摘要】：目的研究GB 5749—2006《生活饮用水卫生标准》中常规监测指示菌与介水传染病之间的相关性。方法从公共卫生科学数据中心获取2014年全国介水传染病发病数据和饮用水常规指示菌监测数据;采用主成分分析对全国22个省市常规指示菌合格率作排名和分级;对常规指示菌与介水传染病及常规指示菌间的相关性采用Spearman偏相关分析。结果在22个省市饮用水常规指示菌合格率分级中,黑龙江省、江苏省、北京市和河北省等级较高。枯水期间除总大肠菌群水平与副伤寒发病率呈正相关(P0.05)外,其他指示菌与疾病之间均无显著相关性;4种常规指示菌间均两两呈正相关(P0.05)。丰水期间除总大肠菌群水平与伤寒、副伤寒发病率呈正相关(P0.05)外,其他指示菌与疾病之间无显著相关性;除大肠埃希菌与菌落总数无显著相关性外,其他常规指示菌间两两呈正相关。结论 GB 5749—2006中的常规指示菌与介水传染病相关性并不显著,建议进一步进行常规指示菌与介水传染病相关性的定量研究及探寻新型指示菌。
[Abstract]:Objective to study the relationship between routine surveillance of indicator bacteria and infectious diseases in drinking water standard GB 5749-2006.Methods the data of infectious diseases and routine indicator bacteria in drinking water were collected from the Public Health Science data Center in 2014, and the qualified rate of routine indicator bacteria in 22 provinces and cities were ranked and graded by principal component analysis (PCA).Spearman partial correlation analysis was used to analyze the correlation between conventional indicator bacteria and infectious diseases.Results in 22 provinces and cities, the grade of qualified bacteria in drinking water was higher than that in Heilongjiang Province, Jiangsu Province, Beijing City and Hebei Province.There was no significant correlation between the total coliform group level and the incidence of paratyphoid fever (P0.05), but there was no significant correlation between the other indicator bacteria and the disease.Except for the total coliform group level and the incidence of typhoid fever and paratyphoid fever, there was no significant correlation between the total coliform group level and the incidence rate of paratyphoid fever (P0.05), but there was no significant correlation between the other indicator bacteria and the disease, except Escherichia coli and the total number of bacteria.There was a positive correlation among other routine indicator bacteria.Conclusion there is no significant correlation between conventional indicator bacteria and intermediate water infectious diseases in GB 5749-2006. It is suggested that further quantitative study on the relationship between conventional indicator bacteria and intermediate water infectious diseases should be carried out and a new type of indicator bacteria should be explored.
