Identification of a novel Aleutian mink disease virus B-cell epitope using a monoclonal antibody against VP2 protein.

•386HLQQNFSTRYIYD398 is a linear B-cell epitope of the AMDV VP2 protein.•Sequence alignments demonstrated that linear epitope is highly conserved among AMDV strains except 386H, and less conserved among Raccoon dog amdovirus, Gray fox amdovirus, Red fox amdovirus, Bat parvovirus and Mink enteritis parvovirus.•The identified epitope can be recognized by AMDV positive serum, it may be useful for clinical applications.
