Fig. 6From: Trypsin-independent porcine epidemic diarrhea virus US strain with altered virus entry mechanismSurvival curves and virus shedding of nursing piglets inoculated with PEDV KD, AA, or 8aa at various passage numbers. a Survival curves of 1–4 day old piglets inoculated with PEDV KD P120 (KD P120), PEDV AA P103 (AA P103), PEDV 8aa P40 (8aa P40), PEDV 8aa P70 (8aa P70) or PEDV 8aa P105 (8aa P105). b and c Virus shedding of piglets inoculated with each strain. Daily rectal swabs were collected and virus shedding was determined by real-time RT-qPCR. The Ct values were converted to TCID50/ml equivalent values (log10). The mean and the standard errors are shownBack to article page
