Genomic and antigenic evolution of influenza A(H3N2) after the COVID-19 era: a scoping review with focus on J and K subclades and implications for vaccine effectiveness

Germs
The objective of this scoping review is to systematically map and synthesize the available evidence on the post-pandemic genomic and antigenic evolution of influenza A(H3N2), with particular focus on emerging antigenic drift variants, including those later designated as subclade K (J.2.4.1), and their implications for vaccine effectiveness and public ...

Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

Zoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

Subclade 2.2.1-Specific Human Monoclonal Antibodies That Recognize an Epitope in Antigenic Site A of Influenza A(H5) Virus HA Detected between 2015 and 2018

, 2019
Highly pathogenic avian H5 influenza viruses persist among poultry and wild birds throughout the world. They sometimes cause interspecies transmission between avian and mammalian hosts. H5 viruses possessing the HA of subclade 2.3.4.4, 2.3.2.1, 2.2.1, or

Genomic, antigenic and transmission dynamics of influenza A(H3N2) subclade K in Canada, early 2025/26 season

Abstract Influenza A(H3N2) subclade K virus was detected in Canada early in the 2025/26 influenza season, bearing an antigenic transition in the hemagglutinin (HA) glycoprotein. Analysis of 396 HA sequences from Canada showed antigenic divergence from 2025/26 influenza vaccine strains, consistent with partial mismatch.

Morphometrics and Mitochondrial (COI‐Based) Molecular Barcoding of Diptychus maculatus Steindachner, 1866, Snow Trout from the Trans‐Himalayan Region of Ladakh, India

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT The present study integrates morphometric analysis, length–weight relationship (LWR), condition factor, and mitochondrial COI‐based molecular barcoding to elucidate the biological characteristics of Diptychus maculatus and confirm species identity, respectively, from the Trans‐Himalayan region of Ladakh, India.

A Novel Mastadenovirus from Nyctalus noctula Which Represents a Distinct Evolutionary Branch of Viruses from Bats in Europe

Viruses
Bats are natural hosts of a wide variety of viruses, including adenoviruses. European bats are known to carry mastadenoviruses categorized as species B (widespread in European Vespertilionidae bats) and whose taxonomy has not been clarified.

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, Volume 309, Issue 10, Page 2790-2837, October 2026.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Characterisation of Typical Enteropathogenic Escherichia coli (tEPEC) and bfpA Genes From Five Bat Species Reveals Australian Pteropus Spp. Are Natural tEPEC Hosts

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This study revealed that Australia's five Pteropus bat species are all natural hosts of typical Enteropathogenic Escherichia coli (tEPEC)—historically considered a human‐specific pathogen. Across the five Pteropus spp., tEPEC prevalence ranged between 14.2% and 37.0%, with 18 bat‐specific tEPEC strain types and 24 bat‐specific bfpA allele types ...
