| Outline of Final Research Achievements |
This study aimed to develop a novel method to detect infectious enteric viruses in water samples. In the first year, cellular responses, including apoptosis, in the early stage of enteric virus infection with human cultivated cells were investigated as possible indicator for the virus detection. As a result, it was shown that infectious enterovirus 71 (EV71) was possible to detect within 12 hours when the concentration in a inoculated sample was high enough. In the second year, the effect of multiple virus infection with host cells on the early detection of infectious viruses was investigated. As a result, the detection of adenovirus 40 (AdV40) was significantly inhibited by the co-infection of EV71. This result implies that the inhibition of EV71 growth is necessary when AdV40 is a target virus in water samples.
