|
We detected waterborne enteric viruses from the raw water and tap water in Busan metropolitan city by the total culturable virus assay of EPA standard method. According to the results of survey from July 2001 to November 2002, thirteen out of twenty one in raw water samples were positive (61.9%) for enteric viruses and all of the treated water and tap water samples were negative. The enteric viruses in raw water were mainly distributed through the summer to the early winter, suggesting the seasonal characteristics of virus distribution in water. The titer of enteric viruses per 100 liters of the raw water was ranged from 1.92 to 9.70 MPN by TCVA-MPN program. The isolated viruses were identified as either human poliovirus type 1 or enteroviruses by the immunofluorescent assay.
