Abstract
Avian bornaviruses (ABV) are the causative agents of proventricular dilatation disease (PDD), a fatal neurological disease considered to be a major threat to psittacine bird populations. We performed a RT-PCR survey to detect the presence of Canary avian bornavirus (CnBV) in passeriformes related to different clinical manifestations, such as sudden death, neurological signs, apathy, anorexy, excessive beak growth and PDD. A total of 227 samples from captive and wild canaries were included, of which 80 samples were captive birds, comprising saffron finches (n=71) and common canary (n=9), and 147 samples were from wild birds distributed among a variety of several species. Two samples from captive birds (2/80) were positive for ABV, and in wild birds, only one sample was positive for ABV. The positive samples were subjected to DNA sequencing, and only the serotype CnBV-1 was found. This was the first time that the serotype CnBV-1 was detected outside of Germany. Phylogenetic analysis confirmed that avian bor...

Background Avian bornaviruses are a genetically diverse group of viruses initially discovered in 2008. They are known to infect several avian orders. Bornaviruses of parrots and related species (Psittaciformes) are causative agents of proventricular dilatation disease, a chronic and often fatal neurologic disease widely distributed in captive psittacine populations. Although knowledge has considerably increased in the past years, many aspects of the biology of avian bornaviruses are still undisc...

Abstract We present the latest version of the Molecular Evolutionary Genetics Analysis (Mega) software, which contains many sophisticated methods and tools for phylogenomics and phylomedicine. In this major upgrade, Mega has been optimized for use on 64-bit computing systems for analyzing larger datasets. Researchers can now explore and analyze tens of thousands of sequences in Mega The new version also provides an advanced wizard for building timetrees and includes a new functionality to automa...

Knowledge of bornaviruses has expanded considerably during the last decade. A possible reservoir of mammalian Borna disease virus has been identified, divergent bornaviruses have been detected in birds and reptiles, and endogenous bornavirus-like elements have been discovered in the genomes of vertebrates of several species. Previous sequence comparisons and alignments have indicated that the members of the current family Bornaviridae are phylogenetically diverse and are not adequately classifie...

Avian bornavirus (ABV) has been identified as the cause of proventricular dilatation disease in birds, but the virus is also found in healthy birds. Most studies of ABV have focused on captive birds. We investigated 86 free-ranging psittacine birds in Brazil and found evidence for natural, long-term ABV infection.

Abstract Avian bornaviruses are the causative agents of proventricular dilatation disease (PDD), a fatal neurological disease considered to be a major threat to psittacine bird populations. We performed a survey of the presence of avian bornaviruses and PDD in pet psittacines in Brazil and also studied PDD's clinical presentation as well as the genomic variability of the viruses. Samples from 112 psittacines with clinical signs compatible with PDD were collected and tested for the presence of bo...

Abstract Avian bornaviruses (ABV) are the causative agents of proventricular dilatation disease (PDD), a widely distributed disease of parrots. Distinct ABV lineages were also found in various non-psittacine avian species, such as canaries, but the pathogenic role of ABV in these species is less clear. Despite the wide distribution of ABV in captive parrots and canaries, its mode of transmission is poorly understood: both horizontal transmission via the urofaecal-oral route and vertical transmis...

SUMMARY An outbreak of proventricular dilatation disease (PDD), a fatal inflammatory disease of psittacines (Aves: Psittaciformes), is described in native Brazilian psittacines. Twenty captive psittacines that died of suspected PDD were necropsied and 10 were submitted to histopathology, reverse transcriptase PCR (RT-PCR), and immunohistochemistry (IHC) for avian bornavirus (ABV). Examined species were one pileated parrot (Pionopsitta pileata), three vinaceous-breasted parrots (Amazona vinacea),...

Abstract Avian bornaviruses (ABV) are known to be the causative agent of proventricular dilatation disease (PDD) in parrots and their relatives (Psittaciformes). A broad range of ABV genotypes has been detected not only in psittacine birds, but also in other avian species including canary birds ( Serinus canaria forma domestica) and Bengalese finches ( Lonchura striata f. dom.), which are both members of the order songbirds (Passeriformes). During this study 286 samples collected from captive an...

Avian bornavirus (ABV) was identified in 2008 as the causative agent of proventricular dilatation disease (PDD) in psittacine birds. In addition, ABV variants were detected in wild waterfowl and in a canary bird. PDD-like diseases were also reported in various other avian species, but it remains unknown whether ABV is involved. In this study we detected ABV in 12 of 30 tested canary bird flocks (40%), indicating a wide distribution of ABV in captive canary birds in Germany. Sequence analysis ide...
