Figure Lengend Snippet: Immortalised primary bovine fibroblasts were pre-treated for 24 h with increasing concentrations of type I IFN prior to a low MOI (0.001 PFU/cell) infection. a , Western blotting for interferon-stimulated genes pSTAT1, Mx1, and RSAD2 at 24 h post IFN-treatment. b , virus in the supernatant of infected cells were titrated by plaque assay on MDCK cells at indicated timepoint post-infection. Data are from three biological repeats and plotted are the titres from each experiment as mean +/− s.d. Data were log-transformed and the statistical significances between IFN treatmented and untreated viruses within each group were measured by two-way ANOVA with Dunnett’s multiple comparisons tests (α = 0.05). P values in bold indicate statistical significance. c and d , Udder slices infected with r-Tx/37/(H5N1) with 10 6 genome copies/slice of tissue. Staining for NP in the duct of udder slices as brown signal in the epithelium and cells detaching from the epithelium. Mx-1 signal is located in the cytoplasm of duct epithelium of udder slices. Confocal images of udder slices with staining for NP and Mx-1 show little colocalization of the signal (merged) in the duct epithelium of infected udder slices. Bars, 100 μm ( c ) and 20 μm ( d ).
