Identification of aviadenovirus and dependoparvovirus in an Adélie penguin fecal sample from Cape Royds (Ross Island, Antarctica)

Arch Virol. 2026 Sep 4;171(10):268. doi: 10.1007/s00705-026-06726-x.ABSTRACTAdenoviruses (Adenoviridae) and their associated replication-deficient dependoparvoviruses (Parvoviridae) are recognized as significant components of the avian virome. While well-studied in domestic birds, these viruses remain underexplored in wild Antarctic birds. Information is limited on viruses circulating in penguins, particularly outside of the Antarctic Peninsula Region. Here we leverage a … Read more

Genomes of cressdnaviricots and phixviricots in a freshwater lake sample from Arizona, USA

Microbiol Resour Announc. 2026 Aug 28:e0092026. doi: 10.1128/mra.00920-26. Online ahead of print. ABSTRACT A viral metagenomic analysis of a 40 ml water sample from a small freshwater lake near Flagstaff, Arizona, USA, resulted in the identification of 295 circular viral genome sequences. Of these, 126 are members of Cressdnaviricota and 169 of Phixviricota phyla. PMID:42663468 … Read more

Effects of Nutrient Limitation on Antarctic Microbial Community Diversity, Composition, and Interactions: A Cryoconite Microcosm Study

Microorganisms. 2026 Aug 16;14(8):1807. doi: 10.3390/microorganisms14081807. ABSTRACT Dry, harsh, nutrient-limited environments such as the McMurdo Dry Valleys, Antarctica, may be particularly susceptible to changes in nutrient availability, demonstrating strong deterministic community assembly processes shaping communities within an ecosystem largely dominated by stochastic processes. Utilizing previously characterized cryoconite hole sediments from Canada Glacier in Taylor Valley, … Read more

Atypical myxomatosis in European rabbits is caused by the recombinant myxoma virus involved in species jumping into hares

bioRxiv [Preprint]. 2026 Jul 27:2026.07.25.740729. doi: 10.64898/2026.07.25.740729. ABSTRACT Myxoma virus (MYXV), a member of the Leporipoxvirus genus (species Leporipoxvirus myxoma; family Poxviridae ), causes a highly lethal disease known as myxomatosis in European rabbits. In late 2018, a new natural MYXV isolate, MYXV-Tol (a.k.a. hare MYXV; ha-MYXV), emerged and caused myxomatosis-like disease with high mortality … Read more

Novel circoviruses identified in short-finned pilot whale and orca from the North Atlantic Ocean

Virology. 2026 Feb;615:110768. doi: 10.1016/j.virol.2025.110768. Epub 2025 Dec 5. ABSTRACT The family Circoviridae comprises viruses with small single-stranded DNA genomes that are known to infect various animals, resulting in considerable morbidity and mortality in some hosts. Circoviruses have been recently identified through metagenomic sequencing in diverse terrestrial vertebrate species, but their distribution and diversity in … Read more

Population ecology and biogeochemical implications of ssDNA and dsDNA viruses along a permafrost thaw gradient

Nat Commun. 2025 Dec 11;17(1):375. doi: 10.1038/s41467-025-67057-0. ABSTRACT Anthropogenic-driven climate change is accelerating permafrost thaw, threatening to release vast carbon stores through increased microbial activity. While microbial roles are increasingly studied, the contributions of viruses remain largely unexplored, in part due to soil-associated technical challenges that have hindered their detection and characterization. Here, we applied … Read more

Canine Parvovirus and Vaccine-Origin Feline Panleukopenia Virus in Wastewater, Arizona, USA: July 2022-June 2023

Microorganisms. 2025 Sep 11;13(9):2124. doi: 10.3390/microorganisms13092124. ABSTRACT Canine parvovirus (CPV) is a virus of veterinary health significance and a member of the Parvoviridae family. Despite its clinical significance and global distribution, surveillance is often limited to cases serious enough to result in veterinary visit and/or hospitalization, thereby limiting our understanding of its evolution and diversity. … Read more

Age-stratified Data Highlight Worldwide Variability in Organ Donation Rates and the Potential Increase in Organ Donation

Transplantation. 2026 Mar 1;110(3):e707-e714. doi: 10.1097/TP.0000000000005564. Epub 2025 Nov 6. ABSTRACT BACKGROUND: Ongoing shortages of organs for transplantation have prompted the critical question of which countries have the highest organ donation rates and how each can increase those rates. The existing metric of donors per million population is flawed because it does not sufficiently account … Read more

Identification and characterization of a novel papillomavirus in thornback skate (Raja clavata)

Microb Genom. 2025 Nov;11(11):001541. doi: 10.1099/mgen.0.001541. ABSTRACT Papillomaviruses are non-enveloped, double-stranded DNA viruses capable of infecting a wide range of vertebrates, from chondrichthyans to mammals. In this study, we report for the first time the identification and complete genome of a papillomavirus in the thornback skate (Raja clavata), named Raja clavata papillomavirus 1 (RclaPV1). The … Read more

Diversity of polyomaviruses and papillomaviruses in penguins from eastern and western Antarctica

Microb Genom. 2025 Nov;11(11):001580. doi: 10.1099/mgen.0.001580. ABSTRACT Polyomaviruses and papillomaviruses are icosahedral viruses with small circular dsDNA genomes. Limited information on their diversity and evolution in avian hosts is available, with even less known regarding Antarctic penguins. Prior to this study, only one polyomavirus and two papillomaviruses had been identified in Adélie penguins (Pygoscelis adeliae). … Read more
