| recombinant expression of a truncated capsid protein of beak and feather disease virus and its application in serological tests. | beak and feather disease virus (bfdv) causes severe disease characterized by irreversible feather disorders and severe immunosuppression in many psittacine species. bfdv cannot be propagated in tissue or cell cultures, rendering virus propagation and thus diagnosis rather difficult. to develop reliable diagnostic methods, the region encoding the bfdv capsid protein c1 was cloned from an infected sulphur-crested cockatoo (cacatua galerita). phylogenetic analysis showed this gene had 76.3 to 83.2% ... | 2004 | 15223562 |
