🔉Out today in Communications Biology - our genomic analysis of earliest H58 S. Typhi organisms isolated from returning travellers to the UK suggests this highly successful lineage emerged in 1987 in India, likely from a chronic carrier, and was already MDR. nature.com/articles/s4200…

The ability of H58 to acquire & maintain AMR genes continues to pose a threat, as the emergence and spread of #XDR typhoid in Pakistan has demonstrated. Continued & expanded 🧬surveillance is needed to inform #TCV introduction and measure its impact #VaccinesWork

How can these findings help to #TakeOnTyphoid? Data found drug resistant transmission and patterns, highlighting the importance for decision-makers to take strategic action to protect communities! #Typhoid conjugate #VaccinesWork to protect against drug resistant strains💉

Great to see so many long term colleagues and friends on this paper. I remember the origins of STRATAA at the Wellcome. Came after we pointed out a gap and an opportunity. It has delivered.

Lovely work from the STRATAA consortium, led by Zoe Anne Dyson Ashton & @DrKatHolt. Consistent community surveillance in Africa and Asia dissected the behaviour of highly localised clusters of S. Typhi w/ AMR spreading between age groups and lasting over several seasons.

New research alert 🔔 A study in The Lancet Microbe by Zoe Anne Dyson reveals high levels of drug-resistant typhoid in Bangladesh, Nepal, and Malawi. Calls for increased focus on vaccination and WASH to combat this public health threat. Read more👇 bit.ly/45X8mz0

📣 🎉 Congratulations to Gladys Maria Pangga and Zoe Anne Dyson on winning our 2025 Publication Prize at London School of Hygiene & Tropical Medicine 🏆 Read more about their winning papers and impactful AMR research🔬 👇 bit.ly/4iM7uCh

Zoe Anne Dyson won the Staff Prize for her work revealing that most AMR typhoid infections in Bangladesh, Nepal, and Malawi are driven by ongoing local transmission of existing resistant strains—not new variants.
