#H5N1 : An infected herd was recently detected in Wisconsin, and genome sequencing indicates that this is yet another spillover event, making it the fourth detected one. How do these spillovers happen and why are they restricted, so far, to the US? www.aphis.usda.gov/news/agency-...

Our lab's paper describing the North American H5N1 epizootic is out now in Nature! So thrilled to have this out, and congratulations to @lambod50.bsky.social for all the fantastic work on this: www.nature.com/articles/s41...

I want to spell this out in case the implications aren't clear: This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited. The file allowed this. Cut that - cut off all tools the public & others were using.

🚨 NEW: The majority holder of the world's genetic sequence data is a bad actor who can cut off access to critics and competing services. We've tolerated this for years, and now it threatens the pandemic treaty. Time for WHO to step in. With @ctrlalttim.com: www.thinkglobalhealth.org/article/to-f...

We’ve identified a highly divergent betacoronavirus from South American bat that encodes a functional furin cleavage site. Another fascinating reminder of how diverse coronavirus evolution is in wildlife reservoirs. #Virology #VirusEvolution #Bats #Coronavirus www.biorxiv.org/content/10.1...

After years in the making, Joe McKellar @viroscope.bsky.social’s final PhD paper is finally out today in PNAS! 🎉 🎉🎉 www.pnas.org/doi/10.1073/...

And the sister paper from collaborator and good friend Katie Doores ... A deeper dive into how some of these broadly neutralising #sarbecovirus #coronavirus #sars2 #covid antibodies actually work www.biorxiv.org/content/10.1...

Our first post on here and it's a doozy 😍🤩. Our epic piece on #sarbecovirus host range. #virology #sars2 #covid #vaccines. Enjoy and please repost. www.biorxiv.org/content/10.1...

Really excited to have been a small part of this work investigating sarbecovirus host range, receptor usage and antigenicity! www.biorxiv.org/content/10.1101/2025.09.03.673949v1

In new study led by @ckikawa.bsky.social, we provide near real-time data on human neutralizing antibody landscape to influenza by measuring ~26,000 titers to >100 recent viral strains Data can inform vaccine selection & evolutionary/epidemiological modeling www.biorxiv.org/content/10.1...

New preprint! If some merbecoviruses use DPP4 and others use ACE2, what do those hedgehog merbecoviruses use?! As it turns out, neither! In our latest study, we uncover the "missing" receptor for the MERS-related viruses in hedgehogs. [These findings were first shared at ASV this year] (1/6)

The cow udder may be a mixing vessel where different strains of influenza can recombine--"underscoring its potential role in generating novel influenza viruses with pandemic risk." [Preprint] www.biorxiv.org/content/10.1...

Finally!

Really excited to have been a part of this study, lead by @willharv.bsky.social on how reassortment of H5N1 in birds has lead to a 'specialist' genotype that thrives in seabirds and drives summer/spring (rather than winter) waves of poultry outbreaks www.biorxiv.org/content/10.1...

Come work with us👇

Very pleased to have our new work out where we perform a structure/function study on the bornavirus polymerase complex with fantastic coauthors. Have a read www.nature.com/articles/s41... @warwicklifesci.bsky.social @loiccarrique.bsky.social @franziskaguenl.bsky.social

🚨 New paper alert! 🚨 Here we show that stabilized influenza hemagglutinin HPAI H5 immunogens improve the quality of elicited antibody responses. Thank you to @open_phil for funding this work! bit.ly/4lgr0rM

Exciting new work from my @ciddpsu.bsky.social colleagues showing that pandemic H1N1 immunity reduces susceptibility to H5N1 infection and disease in ferrets.

🦇 NEW RESEARCH: Our 3-year study of Australian flying foxes identified six co-circulating coronaviruses, with highest rates of infection and co-infection in young bats, and evidence of circulating recombinants 🧪🌏 🧵 Available open access in @natcomms.nature.com 📄 www.nature.com/articles/s41...

Very happy that our paper on the receptor binding properties of contemporary H3N2 viruses is now published @CellReports # glycotime www.cell.com/cell-reports...

This is quite late but our lab has a preprint out about a SARS-CoV-2 situation we had in mink in Lithuania back in 2021. It's a doozy with re-emergence of extinct lineages, a country-wide test of all mink farms in Lithuania & some interesting dynamics in mink. www.medrxiv.org/content/10.1... 1/5🧵

A hybrid coronavirus, formed of cat and dog coronaviruses, caused a severe outbreak of disease among cats in Cyprus, researchers found. Their work, in Nature, showed how this new virus was able to cause widespread cases of Feline Infectious Peritonitis (FIP) among the island’s cats.

I am paw-sitively thrilled to say that out latest work is out in Nature today! #Virology #Genomics #Coronavirus #AnimalHealth #InfectiousDisease #Sequencing #FIP #FCoV23 www.nature.com/articles/s41...

Our new paper on SARS-CoV-2 furin cleavage site is now out at JVI. Study examines disruption (rather than deletion) of the FCS & maintains the longer S1/S2 loop found in #SARS2. FCS disruption attenuates pathogenesis, but not required (but helps) transmission. journals.asm.org/doi/10.1128/...

Excited to present the first review from my lab! Which mutations allow H5 influenza to jump into humans or other mammals? How close is H5 to a pandemic? This review has the answers and explains the molecular mechanism behind the mutations. Led by @fcapelastegui.bsky.social. doi.org/10.1099/jgv....

Rab11B is required for entry of current H3N2 isolates! 1/n www.biorxiv.org/content/10.1...

Happy to have this story now published in @PNAS The Q226L mutation can convert a highly pathogenic H5 2.3.4.4e virus to bind human-type receptors | PNAS #glycotime www.pnas.org/doi/10.1073/...

A flu lineage has likely gone extinct since 2020 🧵

I’m delighted that we could contribute the #cryoEM data to this incredible antiviral discovery project from the group of @neytsjohan.bsky.social 💊 "A coronavirus assembly inhibitor that targets the viral membrane protein" www.nature.com/articles/s41... A huge congrats to everyone involved! 🎉

When the US reported a year ago that the H5N1 avian influenza virus had infected dairy cattle, it seemed some rare confluence of factors had allowed the virus to infect the cows’ udders. Then it happened again. And again. Story in @science.org on some questions about the origins of H5N1 in cows… 🧪

One year after the first infections were reported, it's still unclear how highly pathogenic avian influenza virus H5N1 jumped into U.S. cattle—and why it keeps doing so. Science Insider article by @kakape.bsky.social www.science.org/content/arti...
