Detection of adenoviruses and enteroviruses in tap water and river water by reverse transcription multiplex PCR.
A reverse transcription (RT) multiplex polymerase chain reaction (PCR) assay was developed to simultaneously detect adenoviruses and enteroviruses, both of which have attracted much attention as molecular indices of viral pollution in environmental samples. The method involves a reverse transcription step, followed by a multiplex nested PCR in which the combination of primers amplifies cDNA from enteroviruses and adenoviruses. The sensitivity of this assay was found to be similar to that of each monoplex PCR or RT-PCR assay, and to be consistent regardless of relative concentrations of adenoviruses and enteroviruses. To assess suitability and environmental application of the RT multiplex PCR assay, a total of 12 river water samples and 4 tap water samples were analyzed by RT multiplex PCR, each monoplex PCR or RT-PCR, and cell culture assay on the Buffalo Green Monkey kidney cell line. The sensitivity of the RT multiplex PCR was also found to be similar to that of each monoplex PCR in environmental samples. This suggests the RT multiplex PCR assay could be applied to the routine monitoring of viral pollution in environmental waters.
