Table 1.

Virus titers in tissues of infected chickens. Nine chickens (6 weeks-old) were inoculated intranasally with the viruses at a dose of 105.5 TCID50. Three chickens from each group were euthanized at 3 dpi and5 dpi, and tissue samples (trachea, lung, pancreas, spleen, kidney and bursa of fabricus) were obtained for virus titration. a:2/3 infected chickens were positive for virus detection, and the titer values were shown as (mean ± SD); -: virus was not detected in any chicken.
