Infectious titers of poliovirus inocula dried on stainless steel carriers. An inoculum of 50 μL of culture supernatant fluid containing poliovirus was applied on stainless carriers in duplicate. It was dried and thereafter recovered by using wet flocked swabs at 0, 90 or 150 min. The infectious titers were determined and expressed as Log10 TCID50.mL-1. The results are the mean +/- S.D of three independents experiments.
