The amount of the sample orally administered to the mice is incredibly small. If the 7.13~7.33 log10 TCID50/ml influenza presence is accurate then the sample would have to have been an isolate. 3,000,000 plaque forming units would be just about the total 0.05 milliliters compared to the unaltered sample. This indicates that the mice were not given milk but instead given the isolated virus as a massive concentrated dose into their mouths.
