Rapid Expansion of Highly Pathogenic Avian Influenza A(H5N1) Clade 2.3.4.4b Genotype D1.1 Virus across Flyway Regions, North America, Fall 2024

Emerg Infect Dis. 2026 Jul 13;32(8). doi: 10.3201/eid3208.260205. Online ahead of print.ABSTRACTHighly pathogenic avian influenza clade 2.3.4.4b virus continues to circulate in North America and has caused severe human disease. That clade includes genotype D1.1, which became dominant in birds in late 2024. Recent phylodynamic reconstructions place D1.1 emergence in mid-2024 but differ on its … Read more

ORAL AND GASTRIC PLAQUES, PAPILLOMAS, SQUAMOUS CELL CARCINOMAS AND PAPILLOMAVIRUSES IN SLENDER-HORNED GAZELLES (GAZELLA LEPTOCEROS )

J Zoo Wildl Med. 2026 Jun;57(2):393-405. doi: 10.1638/2024-0055. ABSTRACT The slender-horned gazelle (SHG, Gazella leptoceros) is a small, sand-colored antelope native to northern Africa. It is endangered due to poaching and habitat loss. Limited reports describe health or disease in wild or zoo populations. Mucosal plaques in the oral cavity (n = 2), papillomas in … Read more

Divergent poxvirus identified in a non-native black rat from Madagascar

Virology. 2026 Jun 30;623:111021. doi: 10.1016/j.virol.2026.111021. Online ahead of print. ABSTRACT Non-native rodents serve as bridges between anthropogenic and natural landscapes. They have expanded across the planet alongside humans while bringing competition, predation, and pathogens, such as poxviruses, to naïve ecosystems. Although rodents serve as reservoirs for multiple zoonotic poxviruses, limited research has focused on … Read more

Angiostrongylus cantonensis Rat Lungworm Detected in Rats, Madagascar, 2022-2023

Emerg Infect Dis. 2026 Jul;32(7):1188-1192. doi: 10.3201/eid3207.260142. ABSTRACT Angiostrongylus cantonensis, the rat lungworm, is a zoonotic parasite that causes eosinophilic meningitis in humans; the parasite is maintained in rat definitive hosts and transmitted through gastropod intermediate hosts. We report A. cantonensis prevalence and mitochondrial genome from oral swab specimens from rats in Madagascar, supporting swabs … Read more

Mammal-infecting DNA viruses identified in lemurs and rodents in Madagascar mirror the evolutionary history of their hosts

Microb Genom. 2026 May;12(5). doi: 10.1099/mgen.0.001728. ABSTRACT Given that some DNA viruses have been found to exhibit virus-host co-evolution and establish lifelong infection, mammals with unique evolutionary histories in island ecosystems likely host exceptionally diverse viruses. Madagascar is inhabited by endemic non-human primate and rodent lineages interacting with expansive populations of introduced non-native rodents across … Read more

ICTV Virus Taxonomy Profile: Anelloviridae 2026

J Gen Virol. 2026 Mar;107(3):002222. doi: 10.1099/jgv.0.002222. ABSTRACT The family Anelloviridae includes viruses with circular, negative-sense, ssDNA genomes of 1.7-3.9 kb. Anelloviruses form non-enveloped icosahedral virions constructed of the ORF1 protein, which adopts the single jelly-roll structural fold. Anelloviruses have been isolated from a broad range of birds and mammals, including humans, but are not … Read more

Host-anellovirus interactions in an island ecosystem: non-human primates and rodents in Madagascar harbour diverse, rich anellovirus populations

Microb Genom. 2026 Apr;12(4):001681. doi: 10.1099/mgen.0.001681. ABSTRACT Anelloviruses are circular, negative-sense single-stranded DNA viruses that have remarkable diversity and ubiquity across mammals. However, few studies have attempted to determine anellovirus diversity and dynamics across a biodiverse landscape. Madagascar offers a unique opportunity to study anellovirus diversity, with speciose, endemic mammalian lineages that have evolved in … Read more

Changes to virus taxonomy, the international code of virus classification and nomenclature, and the ICTV statutes ratified by the International Committee on Taxonomy of Viruses (2025)

Arch Virol. 2025 Dec 18;171(1):23. doi: 10.1007/s00705-025-06485-1. ABSTRACT The 56th meeting of the Executive Committee (EC) of the International Committee on Taxonomy of Viruses (ICTV) was held in Bari, Italy, in July/August, 2024, and 115 submitted taxonomy proposals were reviewed. A total of 112 were subsequently ratified by the ICTV membership. An additional 9 error … Read more

Metagenome-assembled genomes of anelloviruses in crowned lemur and aye-aye swabs

Microbiol Resour Announc. 2026 Mar 12;15(3):e0147325. doi: 10.1128/mra.01473-25. Epub 2026 Feb 18. ABSTRACT Two circular, complete genomes of anelloviruses were identified from a crowned lemur anal swab and an aye-aye skin swab from individuals at the Duke Lemur Center (Durham, NC, USA). The anelloviruses represent two species in the Anelloviridae family and expand a developing … Read more

Turbulent dynamo in the terrestrial magnetosheath

Nat Commun. 2026 Feb 18;17(1):2909. doi: 10.1038/s41467-026-69469-y. ABSTRACT Dynamo action refers to energy exchange processes through which magnetic fields are generated at the expense of kinetic energy of the plasma flows. Dynamos can generate magnetic fields across scales larger or smaller than the flows themselves. Multi-scale dynamo processes underpin magnetic phenomena from planetary cores to … Read more
