Dairy cattle movement networks govern the spread and persistence of H5N1 B3.13 in the United States

The paper analyzes the spread of H5N1 B3.13 in U.S. dairy cattle using genomic data and movement networks, finding that cattle movement, not birds, drives the outbreak.

Outbreak of H9N2 avian influenza viruses in lesser rhea in Peru, June-July 2025

The paper reports the first known outbreak of H9N2 avian influenza in lesser rhea in Peru, identifies the virus as low pathogenic North American strain, and finds mutations potentially linked to increased virulence and host adaptation.

Emergence of D1.1 reassortant H5N1 avian influenza viruses in North America

The paper identifies the emergence of D1.1 reassortant H5N1 viruses in North America, which show increased transmissibility, host range, and human spillover potential.

The emergence and molecular evolution of H5N1 influenza viruses in United States dairy cattle

This study tracks the emergence and molecular evolution of H5N1 influenza viruses in U.S. dairy cattle, identifying increased mutation rates and positive selection after spillover from birds.

Begomovirus species demarcation based on genome-sequence identity often yields non-monophyletic species: A case study of sweet potato-infecting begomoviruses

The paper analyzes sweet potato-infecting begomoviruses and finds that genome-sequence identity thresholds fail to produce monophyletic species due to recombination and paraphyly.

Novel Highly Pathogenic Avian Influenza (A)H5N1 Triple Reassortant in Argentina, 2025

Genomic sequencing identified a novel triple-reassortant H5N1 virus in Argentina, highlighting ongoing evolution of clade 2.3.4.4b in the Americas.
