  • a Ferrets were inoculated i.n. with 106 PFU of Perth/09 virus or vaccinated with TIV. ELISA plates were coated with purified Perth/09 inactivated virus. Titers from 4 ferrets per group are for the largest dilution of the sample having a mean optical density greater than the mean plus two standard deviations of the value for the similarly diluted control (unimmunized) sample. ND, not detected; no dilution read above the mean plus 2 standard deviations of the control sample.
