Limited antigenic variation among recent infectious bursal disease virus isolates from France

Limited antigenic variation among recent infectious bursal disease virus isolates from France Seven neutralizing monoclonal antibodies (Mabs) to infectious bursal disease virus (IBDV) were used in an antigen-capture ELISA for the antigenic characterization of 58 IBDV isolates obtained in France since 1989. Fifty-six isolates exhibited an antigenic profile which was different from reference strain Faragher 52/70, and similar to French very virulent IBDV strain 89 163 (no binding of two Mabs). Two strains (3.4%), isolated in 1991 and 1994, showed additional antigenic modifications resulting in suppressed or reduced binding activity of three other Mabs. The two atypical viruses were not re-identified in field samples subsequently collected, hence showing that antigenic variants of IBDV do not tend to replace the antigenically dominant 89 163-like strains that have prevailed in France since 1989. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

Seven neutralizing monoclonal antibodies (Mabs) to infectious bursal disease virus (IBDV) were used in an antigen-capture ELISA for the antigenic characterization of 58 IBDV isolates obtained in France since 1989. Fifty-six isolates exhibited an antigenic profile which was different from reference strain Faragher 52/70, and similar to French very virulent IBDV strain 89 163 (no binding of two Mabs). Two strains (3.4%), isolated in 1991 and 1994, showed additional antigenic modifications resulting in suppressed or reduced binding activity of three other Mabs. The two atypical viruses were not re-identified in field samples subsequently collected, hence showing that antigenic variants of IBDV do not tend to replace the antigenically dominant 89 163-like strains that have prevailed in France since 1989.
