Figure 4
Body temperatures of infected and contact ferrets.
Body temperatures were recorded by rectal thermometer during 10 days post-inoculation in groups of 4 index ferrets infected with 1.25×105 PFU of recombinant A/Brisbane/59/2007-like wild-type (WT) virus as well as H275Y and H275Y/Q222R mutants (A) and in groups of 4 naïve ferrets that were placed in direct contact with index ferrets 24 h later (B).
