Fig. 4From: Effects of physical and chemical factors on pseudorabies virus activity in vitroPRV survival time under different humidity conditions. Plates were quickly air-dried with a fan set to the maximum setting or allowed to air-dry naturally in a biological safety cabinet at a temperature of 26 °C. A sealed plate containing a known titer of PRV cell culture medium was set as a control. The viral titer in each group was determined by a TCID50 assay. The experiment was repeated three timesBack to article page
