| no evidence for adaptation of current egg drop syndrome 1976 viruses to chickens. | in order to determine whether the current field strains of egg drop syndrome (eds) 1976 viruses adapt to chickens, we compared the growth efficiency of three japanese field strains (pa-1/79, awi/98, gifu/01) in chicken and duck embryo liver cells. the growth efficiency in chicken or duck embryo liver cells was almost similar in these strains. the fiber protein may carry the type-specific antigen and the hemagglutination activity, and hexon protein may contain the subgroup-specific antigenic dete ... | 2004 | 15077820 |
