Genetic diversity of the Rep gene of beak and feather disease virus in South Africa.

A study on the genetic variation of Beak and feather disease virus (BFDV) isolates in South Africa was performed by amplifying and sequencing a region within the ORF1 of the genome. Six different BFDV isolates were found in 15 psittacine species from 6 regions within South Africa, representing three unique isolates and three isolates that clustered into a budgerigar lineage (BG) previously described.
