“…APV infection was demonstrated in several species of wild birds: buzzards, falcons, and red-faced lovebirds (9). Furthermore, high prevalence of APV antibody was found in free-ranging greater sulphur-crested cockatoos in Australia (16). It is likely that many other species of birds are susceptible to infection.…”

“…There is strong evidence that APV occurs in wild birds on various continents (16). APV infection was demonstrated in several species of wild birds: buzzards, falcons, and red-faced lovebirds (9).…”
Introduction: The aim of the study was to investigate the occurrence of goose haemorrhagic polyomavirus (GHPV) in wild birds inhabiting Poland. Material and Methods: Samples from 508 birds of different species were obtained between 2010 and 2015. The internal organ sections were homogenised and then total cellular DNA was isolated. The study was performed by means of PCR assay using primers complementary to the VP1 gene of the GHPV. Results: The presence of genetic material of GHPV was detected in 22 (4.33%) samples. Conclusion: It was the first such study in Poland to emphasise the role of wild birds as a potential source of GHPV infection for farmed geese.

Proliferative leg skin lesions have been described in wild finches in Europe although there have been no large-scale studies of their aetiology or epizootiology to date. Firstly, disease surveillance, utilising public reporting of observations of live wild finches was conducted in Great Britain (GB) and showed proliferative leg skin lesions in chaffinches (Fringilla coelebs) to be widespread. Seasonal variation was observed, with a peak during the winter months. Secondly, pathological investigations were performed on a sample of 39 chaffinches, four bullfinches (Pyrrhula pyrrhula), one greenfinch (Chloris chloris) and one goldfinch (Carduelis carduelis) with proliferative leg skin lesions and detected Cnemidocoptes sp. mites in 91% (41/45) of affected finches and from all species examined. Fringilla coelebs papillomavirus (FcPV1) PCR was positive in 74% (23/31) of birds tested: a 394 base pair sequence was derived from 20 of these birds, from all examined species, with 100% identity to reference genomes. Both mites and FcPV1 DNA were detected in 71% (20/28) of birds tested for both pathogens. Histopathological examination of lesions did not discriminate the relative importance of mite or FcPV1 infection as their cause. Development of techniques to localise FcPV1 within lesions is required to elucidate the pathological significance of FcPV1 DNA detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
