Fowl Adenoviruses Type 8b Isolated from Chickens with Inclusion Body Hepatitis in Japan.

Fowl adenovirus (FAdV) type 8b isolated from chickens with inclusion body hepatitis (IBH) in Japan from 2018 to 2019 were characterized serologically and genetically. Serologically, all isolates were well neutralized by antisera against the FAdV-8b strain, but they were not neutralized by antisera against the FAdV-8a strain. Phylogenetic analysis of the part of the hexon protein gene that includes the L1 region revealed that these isolates were all identical.

Intracellular localization of Equine herpesvirus type 1 tegument protein VP22.

Intracellular localization of Equine herpesvirus type 1 (EHV-1) tegument protein VP22 was examined by using a plasmid that expressed VP22 fused with an enhanced green fluorescent protein (EGFP). Also a recombinant EHV-1 expressing VP22 fused with a red fluorescent protein (mCherry) was constructed to observe the localization of VP22 in infected cells. When EGFP-fused VP22 was overexpressed in the cells, VP22 localized in the cytoplasm and nucleus.
