Efficacy and safety evaluation of artificial intelligence-identified antimicrobial peptides for use against avian pathogenic Escherichia coli in the poultry industry

Emre Demirsoy, Teagan I Parkin, Shaeleen E Mihalynuk, Anna H. Dema et autres

ABSTRACT The overuse of antibiotics in both veterinary and human medicine has resulted in the emergence of antibiotic-resistant bacteria, prompting a search for effective alternatives. Antimicrobial peptides (AMP) are short, often cationic, peptide-based molecules with antimicrobial and immunomodulatory activity, which makes them …

Anticoagulant Rodenticide Toxicity in Terrestrial Raptors: Tools to Estimate the Impact on Populations in North America and Globally

John E. Elliott, Veronica M. Silverthorn, Simon G. English, Pierre Mineau et autres

Abstract Anticoagulant rodenticides (ARs) have caused widespread contamination and poisoning of predators and scavengers. The diagnosis of toxicity proceeds from evidence of hemorrhage, and subsequent detection of residues in liver. Many factors confound the assessment of AR poisoning, particularly exposure dose, timing …

Descriptive Epidemiology and Phylodynamics of the “First Wave” of an Outbreak of Highly Pathogenic Avian Influenza (H5N1 Clade 2.3.4.4b) in British Columbia and the Yukon, Canada, April to September 2022

Cassandra L. Andrew, Shannon Russell, Michelle Coombe, James E. A. Zlosnik et autres

Highly pathogenic avian influenza (HPAI) is a viral disease that causes significant rates of morbidity and mortality in domestic poultry and wild birds, with occasional spillover into mammals, including humans. Beginning in November 2021, Canada experienced its longest and largest outbreak of …

Assessing plastic ingestion in birds of prey from British Columbia, Canada

Kerry Schutten, Akshaya Chandrashekar, Madelaine P.T. Bourdages, Victoria Bowes et autres

Since first being introduced for public use in the 1960s, plastic has become one of the most pervasive and ubiquitous forms of pollution globally. The potential fate and effects of plastic pollution on birds is a rapidly growing area of research, but …

Long‐term population decline of a genetically homogeneous continental‐wide top Arctic predator

Marianne Gousy‐Leblanc, Jean‐François Therrien, Thomas Broquet, Delphine Rioux et autres

Genetic analysis can provide valuable information for conservation programmes by unravelling the demographic trajectory of populations, estimating effective population size or inferring genetic differentiation between populations. Here, we investigated the genetic differentiation within Snowy Owls Bubo scandiacus in North America, a species …

A threat from both sides: Multiple introductions of genetically distinct H5 HPAI viruses into Canada via both East Asia-Australasia/Pacific and Atlantic flyways

Tamiru Negash Alkie, Sara Lopes, Tamiko Hisanaga, Wanhong Xu et autres

Abstract From 2016 to 2020, high pathogenicity avian influenza (HPAI) H5 viruses circulated in Asia, Europe, and Africa, causing waves of infections and the deaths of millions of wild and domestic birds and presenting a zoonotic risk. In late 2021, H5N1 HPAI …

Anticoagulant Rodenticide Contamination of Terrestrial Birds of Prey from Western Canada: Patterns and Trends, 1988–2018

John E. Elliott, Veronica M. Silverthorn, Sofi Hindmarch, Sandi Lee et autres

As the dominant means for control of pest rodent populations globally, anticoagulant rodenticides (ARs), particularly the second-generation compounds (SGARs), have widely contaminated nontarget organisms. We present data on hepatic residues of ARs in 741 raptorial birds found dead or brought into rehabilitation …

A novel calicivirus discovered in trumpeter swans (Cygnus buccinator) expands the richness of known avian caliciviruses

Marta Canuti, Laurie Wilson, Victoria Bowes, Tony Redford et autres

Caliciviruses are ssRNA viruses that can infect a wide range of hosts, including birds. While several avian caliciviruses have been discovered, their taxonomy and host distribution are largely unknown. We molecularly characterized a novel calicivirus (trumpeter swan calicivirus: TruSCV) in trumpeter swans …

Are ocean conditions and plastic debris resulting in a ‘double whammy’ for marine birds?

Mark C. Drever, Jennifer Francoise Provencher, Patrick D. O’Hara, Laurie Wilson et autres

We report a mortality event of Red Phalaropes (Phalaropus fulicarius) that occurred from October to November 2016 on the north coast of British Columbia, Canada. All individuals were severely underweight and showing signs of physiological stress. The guts of all carcasses contained …
