Table 6.

Summary of the “log titer “ for each virus as indicated for each indicated condition: “stock”, water dilution (“H₂O”), dilution in cell culture media (“CCM+”), or after a 5-minute formaldehyde (FA) treatment. The final virus infectivity (as TCID50/mL) is shown. FA-treated samples boxed in gray; nd = values < 1.2 log omitted due to failing control well. ** indicates that complete inactivation was reached only in one out of three repeat experiments. Titer reduction is shown compared to the initial virus stock.
