Fig. 8From: The M, F and HN genes of genotype VIId Newcastle disease virus are associated with the severe pathological changes in the spleen of chickensViral load of the chimeric viruses in the spleen. Tissue virus loads were determined in chicken embryo fibroblasts and expressed as the average mean titers (log10 TCID50/g tissue). Error bars show standard error of the mean (SEM). Virus titers were analyzed among the chimeric viruses derived from the same backbone using one-way ANOVA followed by LSD multiple-comparison test. Asterisk (*) indicates significant difference at p < 0.05. The dotted lines indicate the lower limit of virus detectionBack to article page
