Figure 5. Elution of influenza A(H9N2) viruses (UDL-01/08 and SKP-827/16 A/T/V180) from Pakistan from erythrocytes. Virus elution was recorded at 1, 2, 3, 4, 5, 6, and 24 hours posttreatment with bacterial receptor-destroying enzyme. Points plotted indicate hour at which full loss of hemagglutination was achieved for each concentration of receptor-destroying enzyme. A) Canine erythrocyte elution with UDL and 827 A/T/V180; B) chicken erythrocyte elution with UDL and 827 A/T/V180; C) guinea pig erythrocyte elution with UDL and 827 A/T/V180. mgP, milligram of protein.
