摘要

A high level replication fowl adenovirus (FAdV) isolate capable of reaching a viral titer of at least 3 log 10 is described. Said FAdV is a non-pathogenic strain of fowl adenovirus serotype 4, identified as FAdV-4 ON1. Additionally, the present disclosure also provides a viral vector comprising the fowl adenovirus, which has inserted an exogenous nucleotide sequence coding for at least one antigenic site of a disease of concern, as well as a method for obtaining said viral vector and an immunogenic composition comprising the same.
