Cutaneous and diphtheritic avipoxvirus infection confirmed by PCR in a great horned owl (Bubo virginianus) in Mexico

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract A juvenile female great horned owl (Bubo virginianus) from Nuevo León, Mexico, presented with proliferative eyelid, beak, and pedal lesions, and yellow nodules on the hard palate. Histopathology revealed epidermal hyperplasia, ballooning degeneration and numerous eosinophilic intracytoplasmic inclusion bodies (Bollinger bodies), which are ...

Phylogeny Drives Carrion Consumption by Vertebrate Scavengers Towards Distantly Related Species

Ecology Letters, Volume 29, Issue 9, September 2026.
Carrion is a highly nutritious resource that plays a key role in ecosystem functioning, but may pose pathogen risks, particularly between phylogenetically close carcass‐scavenger pairs. Using camera traps, we assessed how phylogenetic distance influenced scavenging in a Mediterranean wetland.

New Type of Papillomavirus and Novel Circular Single Stranded DNA Virus Discovered in Urban Rattus norvegicus Using Circular DNA Enrichment and Metagenomics. [PDF]

PLoS ONE, 2015
Rattus norvegicus (R. norvegicus) are ubiquitous and their presence has several effects on the human populations in our urban areas on a global scale.

Demographic responses to population recovery illustrated by 30 years of monitoring a once critically endangered parrot

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings highlight the dynamic nature of demographic processes throughout population recovery and emphasise the value of continued monitoring beyond apparent recovery to detect density‐dependent shifts in demographic rates of wildlife populations.

A blocking ELISA for the detection of antibodies to psittacine beak and feather disease virus (BFDV) [PDF]

Journal of Virological Methods, 2009
Currently, the only diagnostic test available routinely for the sero-diagnosis of BFDV is the haemagglutination-inhibition (HI) assay. This test, whilst useful and applicable to samples from a wide range of psittacine birds, is not an ideal assay; it requires erythrocytes from live animals, virus purified from the feathers of infected birds and ...

Clinical approach to small psittacines and passerines

In Practice, Volume 48, Issue 4, Page 181-189, May 2026.
Background: The most commonly encountered small avian species in clinical practice are psittacines, such as budgerigars, cockatiels and lovebirds, and passerines, such as finches and canaries. These birds are increasingly presented for veterinary treatment, with owners expecting a high standard of care.

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.

Molecular detection and analysis of beak and feather disease viruses in Iran

Frontiers in Veterinary Science, 2022
The beak and feather disease virus (BFDV) is one of the few pathogens capable of causing extinction of psittacines. To determine the prevalence and the nature of BFDV mutation, this study investigated the presence of the BFDV among 1,095 individual birds

Climate Change Projected to Double the Richness and Abundance of Soilborne Phytopathogenic Fungi in Southern Maritime Antarctica

Global Change Biology, Volume 32, Issue 5, May 2026.
We sequenced fungal DNA in barren soils sampled from 12 sites along a 1900‐km transect through sub‐ and Maritime Antarctica and Patagonia. Using LASSO regression, we found air temperature ‐ and notably mean annual air temperature (BIO1) ‐ to be a highly significant predictor for the richness and relative abundance of soilborne plant pathogens.

Molecular Survey of Pathogens in Wild Amazon Parrot Nestlings: Implications for Conservation

Diversity, 2021
South America presents the greatest Psittacidae diversity in the world, but also has the highest numbers of threatened parrot species. Recently, exotic viruses have been detected in captive native psittacine birds in Brazil, however, their impacts on the
