Congratulations to Burrell St Sexual Health: First UK patient into SOS Global - Evaluating mucosal shedding of spirochetes in heterosexual individuals with syphilis. Great collaboration led by Melbourne Sexual Health Centre focused on understanding syphilis transmission.

In a trial in healthy U.K. adults who were challenged with S. Paratyphi A in a controlled human infection model, two doses of the candidate vaccine CVD 1902 led to protection against S. Paratyphi A infection. Full VASP phase 2b trial results: nej.md/3Lypfd5 #MedSky #IDSky

Want to come work on SNAP, BALANCE+, and STRAP? And change how we treat and manage bloodstream infections? See below. #IDSky

I am exciting to publish our validated, lab-based model of oral gonorrhoea infection! With this model we can begin to understand how gonorrhoea behaves in the mouth (which is lacking) and screen for new compounds for interventions such as a gum to prevent infections. sti.bmj.com/content/earl...

Phenomenal piece of work by a great team across @mrcunitgambia.bsky.social @lshtm.bsky.social @sheffielduni.bsky.social - Delighted to have played a small part in combining epidemiology & immunology to shed light on what protection for #StrepA might look like & help advance vaccine development.

Fantastic to see this immense body of excellent work published! Well done @alexjkeeley.bsky.social and everyone involved 👏 #StrepA @floreyinstitute.bsky.social @molmicrosheffield.bsky.social

VERY excited by our latest work on StrepA below, but also rhe multiple collaborations and work to come off the back of this at MRCG

Latest from @mrcunitgambia.bsky.social #StrepA group. Show clinical decision rules developed elsewhere (mostly HIC) have poor performance in Gambia & molecular tests detect far more #StrepA than culture. Given burden of RhD in Africa we urgently need better & affordable tests for #StrepA diagnosis

Mr T Mkaliainga presents unpub data re verbal autopsies of RHD deaths with caregivers in Malawi and their experiences. Overall the caregivers report thankfulness but a recurrent theme is a distrust of BPG and attribution of mortality to this - another call 4 better Strep A marketing #LISSSD #idsky

@stephlo.bsky.social & global partners describe the extent (worldwide) of intra-country spread (<4 years) of pneumococcus through in silico genotyping, then outlines genotypic methods of predicting vaccine escape (capsules 33F -> 33E) using this in silico data. #LISSSD25 #idsky

Jewish Labour Bund activist Dr Marek Edelman, who was the last surviving #WarsawGhettoUprising ZOB commander (Jewish Combat Organisation). The uprising began on April 19 1943. Like Marek in this photo (I imagine) we will never forget to honour the memory of fallen comrades.

Great to see the funding for the STRAP trial. A linked UK funding application should be going in imminently.
