NewsStudy of influenza D in human cells and tissue hints at spillover potential
The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows.

NewsCinnamic acid blocks plasmid conjugation to slow antibiotic resistance spread
A new study reveals that cinnamic acid, a widely used food additive found in cinnamon, can effectively inhibit plasmid‑mediated conjugation, a major route for the global spread of antibiotic resistance genes (ARGs).

NewsMalaria shaped distribution of early human populations
Scientists investigated whether Plasmodium falciparum induced malaria shaped human habitat choice between 74,000 and 5,000 years ago, finding that malaria influenced habitat choice by pushing human groups away from high-risk environments and separating populations across the landscape.

NewsScientists find a new way coronaviruses can get into human cells
An international team of researchers has identified an East African bat coronavirus capable of entering human cells. Whilst the virus can bind to a cell receptor found in the human lung, preliminary testing in Kenya suggests it has not spilled over into the local human population.

NewsResearch on tick-transmitted disease reveals potential weakness, opening paths to new treatments
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Scientists have isolated and studied a set of proteins that play a central role in infection, revealing a potential weakness.

NewsNew clues to hepatitis B species restriction could help build a novel model for studying infection and testing therapies
For decades, it was thought that the barrier to creating a workable mouse model for hepatitis B is an inability for the virus to gain a genetic foothold in the mouse due to its unique type of DNA. Now researchers have discovered that the problem is something different altogether—likely a misstep in the entry process.

NewsNew research reveals cell proteins that drive severe viral infections
Researchers have identified two human cell proteins, NUP98 and NUP153, that play a crucial role in how viruses such as tick-borne encephalitis virus (TBEV), West Nile virus, and dengue virus replicate in the body.

NewsNovel research reveals the active role that skin cells play in rabies infection
A new study provides direct evidence that keratinocytes can support viral replication and transmit the rabies virus to neurons. The investigators offer a mechanistic explanation for how superficial skin exposures from scratches or minor bites by dogs and bats can lead to neuroinvasion.

NewsFirst continent-wide map of dominant avian influenza strain explains its spread
Scientists provided the most complete view of bird flu’s spread through wild bird populations across North America, explaining how the dominant strain advanced, maintaining the risk of human infections.

NewsAfrican swine fever is quietly spreading across Nepal’s pig sector
A new study provides the first comprehensive analysis of African swine fever outbreaks in Nepal, revealing a disease that has quietly dismantled livelihoods, disrupted food security, and exposed deep gaps in the country’s animal health system — with no vaccine in sight.

NewsUnraveling the complexities of the Borna disease virus 1
Researchers have published the first detailed structural description of the nucleoprotein-RNA complex in the family Bornaviridae. Their observations revealed the three-dimensional structure of this nucleoprotein-RNA complex, showing ring-like assemblies and viral RNA binds in the inner groove.

NewsTwo research projects to study immune responses to dengue and Zika viruses
Dr. James Earnest, an assistant professor at the Burnett School of Biomedical Sciences, is leading two new research projects to examine how humans build an immune response to dengue and the Zika virus over time, in pursuit of creating better preventative measures.

NewsWildlife trade increases pathogen transmission
A study combining forty years of legal and illegal wildlife import-export data with compilations of host–pathogen relationships found that wild mammals that are traded are 1.5 times more likely to share infectious agents with humans than those that are not involved in trade.

NewsAfrican swine fever: a novel model for assessing transmission between domestic pigs and wild boar
Researchers have developed an innovative multi-host epidemiological model for African swine fever incorporating both pig farms and wild boar habitats and calibrated using empirical outbreak data. The model uses detailed data from the first phase of the Romanian epidemic.

NewsA smarter way to build vaccines: scientists harness AI to target emerging alphaviruses
Scientists have developed a new computational pipeline that could dramatically accelerate the development of vaccines against a group of mosquito-borne viruses known as alphavirus.

NewsRapid and visual on-site detection system for Epizootic Hemorrhagic Disease Virus
Epizootic Hemorrhagic Disease (EHD), a vector-borne disease affecting both wild and domestic ruminants, is transmitted by biting midges of the genus Culicoides. Researchers developed a rapid and visual test strip for EHDV RNA detection based on RT-ERA and CRISPR-Cas12a.

NewsPhase I study for human monoclonal antibody for Lyme disease demonstrates safety, tolerability, pharmacokinetics
A Phase I clinical trial of a human monoclonal antibody discovered and developed for the prevention of Lyme disease in the U.S. was well tolerated and showed lasting serum concentrations in participants, according to data.

NewsBird flu spread could be impacted by where waterfowl like to live
The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations. Researchers found that birds travel much shorter distances in areas with human activity.

NewsThree-dimensional microscopy reveals how tick-borne virus replicates
Researchers show how tick‑borne viruses remodel human cells into virus factories, using an advanced microscopy method. The findings provide new insight into how the virus replicates and matures, knowledge that may become important for future treatments against TBE.

NewsUnlocking how dogs’ fungal ear infections evade treatment points vets to drug stewardship
Mutations in a key protein make a yeast found in dogs with common outer ear infections more resistant to the topical antifungals used to treat it, veterinarians and pathobiologists found in a new study.
