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

Author:
Kondiah, K.; Albertyn, J.; Bragg, R. R.

Archives of virology 2006 v.151 no.12 pp. 2539-2545
ISSN:

Subject:
Beak and feather disease virus; budgerigars; genes; genetic variation; South Africa
Abstract:
... 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 describ ...

Abstract:
... Beak and feather disease virus (BFDV), a member of the genus Circovirus, was detected in six dead African grey parrots (Psittacus erithacus) in Portugal. The complete nucleotide sequences of these six BFDVs (PT05, PT08, PT08-2, PT08-3, PT09, and PT09-2) were determined and analyzed. The seven open reading frames (ORFs) described for other BFDVs were detected in all strains, except for PT05 and PT0 ...

Abstract:
... Beak and feather disease virus (BFDV) is a significant pathogen both for wild and captive psittacine birds globally. Genotypic differentiation of BFDV isolates is crucial to establish effective control strategies for the conservation of endangered species and epidemiological investigations of disease outbreaks. The technique developed in this study is a simple, rapid and inexpensive genotyping met ...

Abstract:
... Beak and feather disease virus (BFDV), which causes psittacine beak and feather disease (PBFD), is known to infect a wide range of bird species, with all members of the Psittaciformes recognised as being susceptible. Across the world, genetically distinct circovirus species cause feather disease akin to PBFD in the Australian Raven (Corvus coronoides), as well as a wide range of columbids, anatids ...

Abstract:
... Pathogen outbreaks in the wild can contribute to a population’s extinction risk. Concern over the effects of pathogen outbreaks in wildlife is amplified in small, threatened populations, where degradation of genetic diversity may hinder natural selection for enhanced immunocompetence. Beak and feather disease virus (BFDV) was detected for the first time in an island population of red-crowned parak ...

Abstract:
... Psittacine beak and feather disease (PBFD) is one of the most significant viral diseases in psittacine birds. The aim of the presented study was to develop a highly specific and sensitive TaqMan real-time PCR assay for universal detection of beak and feather disease virus (BFDV). Primers and a hydrolysis probe were selected on the highly conserved regions belonging to the ORF1 of the BFDV genome w ...
