Emergence and interstate spread of highly pathogenic avian influenza A(H5N1) in dairy cattle

This study identifies a reassortment event in wild birds leading to HPAI A(H5N1) infection in cattle and highlights the risk of virus spread through asymptomatic cattle to humans.

Neu5Gc binding loss of subtype H7 influenza A virus facilitates adaptation to gallinaceous poultry following transmission from waterbirds but restricts spillback

This study shows H7 influenza A viruses lose Neu5Gc binding during adaptation to chickens, enhancing transmissibility in poultry but reducing transmission back to wild birds.

SARS-CoV-2 occurrence in white-tailed deer throughout their range in the conterminous United States

This study reports SARS-CoV-2 infection and exposure in white-tailed deer across the conterminous US, showing decreasing prevalence and increasing seroprevalence over time.

Pathology of natural infection with highly pathogenic avian influenza virus (H5N1) clade 2.3.4.4b in wild terrestrial mammals in the United States in 2022

The paper reports the first cases of H5N1 avian influenza in wild mammals in the US, showing neurological symptoms and lesions linked to bird-to-mammal spillover.

Intercontinental movement of H5 2.3.4.4 Highly Pathogenic Avian Influenza A(H5N1) to the United States, 2021

The paper tracks the intercontinental spread of H5N1 avian influenza to the U.S. via wild waterfowl movement in 2022.

SARS-CoV-2 exposure in wild white-tailed deer (Odocoileus virginianus)

The paper detects SARS-CoV-2 antibodies in 40% of wild white-tailed deer sampled from four U.S. states in 2021.

An outbreak of SARS-CoV-2 with high mortality in mink (Neovison vison) on multiple Utah farms

This paper reports an outbreak of SARS-CoV-2 in mink farms in Utah, showing rapid transmission, high mortality, and tissue-specific viral distribution.

Natural SARS-CoV-2 infections, including virus isolation, among serially tested cats and dogs in households with confirmed human COVID-19 cases in Texas, USA

The study investigates SARS-CoV-2 infections in cats and dogs from households with human COVID-19 cases, finding 47.1% of cats and 15.3% of dogs tested positive, with most asymptomatic and viral RNA persistence observed.

From people to Panthera: Natural SARS-CoV-2 infection in tigers and lions at the Bronx Zoo

The paper reports the first natural SARS-CoV-2 infections in tigers and lions at the Bronx Zoo, identifying two distinct viral strains and suggesting human-to-animal transmission.
