Infection and proliferation of isolated strains in PAMs. (a) Passages of GDHZ109/2020 and GDYS162/2022 in PAMs were detected at 40x magnification. (b) PAMs were infected with GDHZ109/2020 and GDYS162/2022 at an MOI of 0.1. The viral supernatants were collected at indicated time points from infected cells and titrated by IFA. All tests were performed in triplicate and repeated twice (; ).
