| Abstract: | A strain of porcine epidemic diarrhea virus (PEDV), P-5V, utilized as a live virus vaccine in Japan was infected to a swine cell lines, KSEK6 and IB-RS-2 cells. Clear CPE, characterized by cellular destruction, started to appear in the infected cells on 2-3 days post infection (DPI) and affected cells was completely degenerated on 4 DPI. The virus was serially passaged in the cells even without addition of trypsin. Small but clear plaques were formed under an agar overlay medium on the cells. The infective titer in the order of 10(7.00-7.50) TCID50 per ml was obtained at usual incubation temperature. |
