Relatedness of Gardnerella prophages and their endolysins

bioRxiv [Preprint]. 2026 Sep 29:2026.09.28.754664. doi: 10.64898/2026.09.28.754664.ABSTRACTThe Gardnerella genus includes a complex sub-taxonomy of bacterial species and subgroups which have been implicated in bacterial vaginosis. We analyzed G. leopoldii, G. swidsinski, G. piotii , and G. vaginalis genomes available in public databases and predicted proviral sequences using Cenote-Taker3. We clustered 266 prophage sequences into 140 … Read more

ICTV Virus Taxonomy Profile: Bacilladnaviridae 2026

J Gen Virol. 2026 Sep;107(9). doi: 10.1099/jgv.0.002321. ABSTRACT Bacilladnaviridae is a family of viruses with single-stranded, circular DNA genomes that range from 3.4 to 6 kb and contain a short double-stranded region of 0.5-1 kb. The genome is replicated by the rolling-circle mechanism. Bacilladnavirids encode a jelly-roll capsid protein which forms non-enveloped icosahedral capsids with … Read more

New Parvovirus and Other Swab-Associated Viruses Identified in the Eurasian Goshawk (Astur gentilis)

Pathogens. 2026 Sep 5;15(9):942. doi: 10.3390/pathogens15090942. ABSTRACT Cloacal swabs were collected from 12 Eurasian goshawk chicks during routine veterinary inspections to evaluate the gut-associated virome of goshawks used for falconry. The material was used for metagenomic screening with high-throughput sequencing. Sequences belonging to several viral families (Poxviridae, Circoviridae, Anelloviridae, Retroviridae, Parvoviridae and Astroviridae) were detected … Read more

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. ABSTRACT Adenoviruses (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 … 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

Three Distinct Circovirids Identified in a Tapeworm Recovered from a Bobcat (Lynx rufus)

Incidence and diversity of circoviruses, polyomaviruses, and adenoviruses in exotic free-roaming rosy-faced lovebirds from Phoenix, Arizona, USA

Incidence and diversity of circoviruses, polyomaviruses, and adenoviruses in exotic free-roaming rosy-faced lovebirds from Phoenix, Arizona, USA Kraberger, S., Custer, J. M., Hammond, R., Gibson, M., Aguiar de Souza Penha, V., McGraw, H., Fountain-Jones, N. M., Olivo, D., Vargas, K. L., Kaján, G. L., Harrach, B., McGraw, K. J. & Varsani, A., Oct 2025, In: … Read more
