Phylogenetic Analysis of Fowl Adenoviruses Isolated from Chickens withGizzard Erosion in Japan

[摘要] References(18)Thirty-four fowl adenoviruses (FAdVs) isolated from chickens with gizzarderosion (GE) from 1999 to 2010 were characterized phylogenetically together with foreignisolates. The phylogenetic analysis based on part of the hexon gene classified these 34FAdV isolates into 3 groups: FAdV-1, �?8a and 8b, thereby suggesting that FAdVs associatedwith GEs in chickens are diverse. All 30 FAdV-1 isolates were genetically identical, andthey were also identical with FAdV-1 isolates from GEs in chickens in European countries(Germany, Poland, Austria, Hungary and Italy). Thus, the same type of FAdV-1 has beenassociated with outbreaks of GE in Japanese chickens for the past 10 years, which may havespread from a common ancestor, although the epidemiological relationship is unknown.
