Figure 2. Virus replication expressed as Cp values at different times after infection of GF-1 cell cultures.

A) Cell-associated compartment. No detectable virus genome was found at 0 dpi. Samplings 0–14 dpi: Significant changes between all samplings separated one week or more in time (P<0,001–0,05), 14 dpi: significant change to 24 dpi (P<0,05). B) Supernatant. Samplings 0–7 dpi: Significant changes compared to all samplings in the study (P<0,001–0,01), 14 dpi: significant change to 21 (P<0,01) and 24 dpi (p<0,05) (One way ANOVA). The cells were washed after 4 h of incubation with virus, and samples were collected sequentially, as indicated, post infection. The 0 h time point is the first sampling after incubation and washing. The experiment included three parallels at each time point (n = 3).
