Fig. 6. Viral replication of H9N2 viruses from ex vivo cultures of the tree shrew respiratory tract.

Fig. 6

Tissues isolated from different sites of the respiratory tract were infected with 106 TCID50/mL of H9N2 viruses (Y280-wt or Y280-PB2-E627K) at 37 °C. Virus titers in ex vivo culture of tree shrew nasal turbinate (a), trachea (b), and lung (c) tissues (n = 3 per time point) were determined by TCID50 assays. Asterisks represent statistical significance compared to 1 hpi. *p < 0.05
