【摘要】：目的探讨海河流域诺如病毒与新型指示微生物——通用拟杆菌的相关性。方法于2013年12月—2014年11月对天津海河流域水中的粪大肠菌群、F(+)噬菌体、通用拟杆菌3项指示微生物和沙门菌、诺如病毒2项致病微生物进行监测。结果粪大肠菌群浓度为0~6.85×10~4 CFU/100 ml,F(+)噬菌体浓度为0~7.70×103 PFU/L,通用拟杆菌浓度为0~6.07×10~6copies/ml,沙门氏菌检出率为30.95%,诺如病毒检出率为27.38%。统计学分析显示,粪大肠菌群与沙门菌具有相关性(r=0.243,P0.05),与诺如病毒没有相关性;通用拟杆菌与诺如病毒具有相关性(r=0.289,P0.01),与沙门菌没有相关性;F(+)噬菌体与沙门菌和诺如病毒均没有相关性。结论海河流域中诺如病毒与通用拟杆菌具有相关性,而与粪大肠菌群无相关性。
[Abstract]:Objective to investigate the relationship between Norovirus and a new indicator microorganism, Bacteroides generalis.Methods from December 2013 to November 2014, the bacteriophage of fecal coliform group F (), three indicator microorganisms of Bacteroides generalis and Salmonella, two pathogenic microorganisms of Norovirus in Haihe River basin of Tianjin were monitored.Results the concentration of fecal coliform bacteria was 0.0.85 脳 10 ~ (4) CFU/100 路ml ~ (-1) bacteriophage was 0.0.70 脳 10 ~ (3) PFU / L, the concentration of Bacteroides generalis was 0.6.07 脳 10 ~ (6) copias / ml, the detection rate of Salmonella was 30.955 and the detection rate of norovirus was 27.38%.Statistical analysis showed that fecal coliform was correlated with Salmonella, but not with norovirus.There was no correlation between the bacteriophage and Salmonella and norovirus and the bacteriophage had no correlation with Salmonella and Norovirus. The results showed that the bacteriophage had no correlation with Salmonella and Norovirus. The bacteriophage had no correlation with Salmonella and norovirus.Conclusion there is a correlation between Norovirus and Bacteroides generalis in Haihe River Basin, but no correlation with fecal coliform bacteria.
