1. UV inactivation and resistance of rotavirus evaluated by integrated cell culture and real-time RT-PCR assay.

Rotaviruses are double-stranded RNA viruses which are among the most resistant waterborne enteric viruses to UV disinfection. An integrated cell culture and real-time RT-PCR (ICC real-time RT-PCR) assay was developed to detect the infectivity of rotaviruses in water, which uses real-time RT-PCR to...
