The genomic organization of egg drop syndrome virus strain AA-2 isolat
ed in China is reported here. The genome was found to be 32 838 bp in
length, approximately 2 kb shorter than those of the human subgenus C
adenoviruses. Analysis of open reading frames indicated that the genes
for major viral structural proteins (55 K, Penton base, pVII, pX, pVI
, Hexon, 100 K, pVIII and Fiber), as well as EP, DNA polymerase and IV
a II are present in the expected locations in the genome. EDSV posses
ses no identifiable E3 and E4 regions and most proteins encoded by E3
and E4 regions of other adenoviruses genome were not presented in EDSV
.
