Figure 2.
(a) Immunofluorescence assay of MDBK cells infected with BPIV-3 SC (MOI = 1) at 36 h post-infection. The specific fluorescence was observed in BPIV-3-infected MDBK cells, and mock-infected MDBK cells were used as the negative control. (b) Paramyxovirus-like particles were observed under transmission electron microscopy (bar = 100 nm). The red arrows point to the virus particles.
