Fig. 1From: Newcastle disease virus infection in chicken embryonic fibroblasts but not duck embryonic fibroblasts is associated with elevated host innate immune responseComparison of multicycle growth kinetics and progeny virus outputs of SS-10 and NH-10 strains on chicken embryo fibroblasts (CEFs) and duck embryo fibroblasts (DEFs). CEFs and DEFs were inoculated with SS-10 (a) and NH-10 (b) at a moi of 1, and cell supernatant was sampled at the time points indicated. Virus titers in the cell supernatant were determined in CEFs via plaque assay. SS-10 (c) and NH-10 (d) at a moi of 1 conferred higher levels of accumulation of P/V/W gene RNA in CEFs than in DEFs. Values represent averages of the results from three independent experiments with standard error bars. *p < .05, **p < .01, ***p < .001, as determined by an unpaired Student’s t-testBack to article page
