Samples include distilled H2O (1 L) with treatments sediment (7.5, 25, 50, and 100 g/L), pH (4,6,8,10), salinity (0.05, 1.0, 3.0, and 35 g/L) and temperature (4, 20 and 30 °C) spiked with EHV-1 (103.5 TCID50/ml). Run over 21 days are sampled at six different points (days). +denotes positive for any CPE in cell culture. −denotes negative for any CPE in cell culture.
