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
