Imagine youโre a plasmid conjugating into a recipient cell. How would you overcome CRISPR-Cas and other bacterial defense systems? Encoding anti-defense mechanisms is one obvious way.
But where? And how? @BruriaSamuel set out to explore! ๐งต 1/6

Contrast below Tweet w one in tweet 22 of same thread by @veeslerlab
XBB.1 only has ~4-fold decrease in antibody *binding* to RBD but ~100+ fold decrease in *neutralization*
Underscores how SARS-CoV-2 preferentially evolving to escape antibody neutralization rather than binding
We're happy to announce that https://t.co/V6wjsrjajZ now has weekly updated #RSV analyses:

Thanks to Laura Urbanska at @unibasel_en, who has set up a full genome analysis, as well as analyses focusing on the genes G and F for RSV A & B.

too bad this study wasn't posted on a preprint server -- the community would have had an opportunity to discuss the data and give feedback to the authors before it ends up in final form in a journal. 5/5
Huge congrats to @richardneher for receiving the 3rd Symposium for Emerging Viral Diseases @gcevd Award! So well deserved for tireless hard work during the pandemic and on @nextstrain!
For his award lecture he will speak on adaptive evolution in #influenza & #SARSCoV2.
In new study, we examine evolution of #SARSCoV2 mutation spectrum. https://t.co/KkcVh7UUEg
TLDR: There have been changes in relative rates of mutations during SARSCoV2โs evolution, & mutation spectrum is becoming more similar to other sarbecoviruses.
Thread below.
๐Coming in 2023: The Hodcroft Lab!!๐
I'm so so excited to announce that my @snsf_ch Starting Grant was funded!
I'll be focusing on the amazing world of #Enteroviruses at the fantastic @SwissTPH as an Assistant Prof!

๐The new and improved https://t.co/wVE7ucgcg6 is here! ๐
We're hoping to make this a one-stop location to track not only the 'headline' variants, but many different #SARSCoV2 mutations & variants that scientists are keeping an eye on.
Let's take a tour of the site!

Paper by @gonzalezreiche Sordillo @VivianaSimonLab van Bakel et al showing onward transmission of highly mutated #SARSCoV2 variant that evolved in chronic infection. This may be first explicitly documented example of transmission from chronic infection https://t.co/5nNqqG0z5j
We're now starting to see the evolution of new potentially impactful sublineages of Omicron with particular focus on mutations at spike residue 452. Here, I'd like to highlight lineages B.2.12.1 in New York, as well as BA.4 and BA.5 in South Africa. 1/17
Where do variants of concern come from?
In a study led by @SheriHarari we compared mutations across 27 chronic infections, ๐งต below :
https://t.co/4BflURlHKK. TL;DR: we think a trade-off between immune evasion and transmissibility constrains evolution in chronic infection.
we are on a biorxiv spree.... check this out, cool & super easy method to find real mutations from MinION sequencing, with @ugophna :
