纸片法快速检测生活饮用水中总大肠菌群的探讨

Study on rapid detection of total coliform bacteria in drinking water by paper strip method

目的探讨使用纸片法快速检测生活饮用水中大肠菌群的可行性。方法使用纸片法与多管发酵法同时检测本地区收集的水样106份,对两种方法对大肠菌群的检出率进行比较。结果在106份生活饮用水水样中,多管发酵法和纸片法均检出总大肠菌群阳性2份,组间差异无统计学意义(P>0.05)。结论纸片法可以达到快速、准确、简便地检测总大肠菌群的目的,可以用于快速、便捷的检测生活饮用水。

Objective To investigate the feasibility of rapid detection of coliform bacteria in drinkingwater using paper strip method.Methods Simultaneous detection of106samples of water collected in the regionby using paper strip and multiple-tube fermentation.The detection rate of coliform bacteria by two methodswere compared.Results In106drinking water samples,2samples with total coliform bacteria positive detectedby the multiple-tube fermentation and the paper strip method,and there was no statistically significant differencebetween the two groups.Conclusion The paper strip method can quickly,accurately and conveniently detectthe total coliform bacteria,and can be used to detect drinking water quickly and conveniently.
