We wrapped up #IMMEM XIV over the weekend and it was a fantastic success with over 250 participants from 35 countries. A big thank you to the organisers and specifically @esgem-sg.bsky.social our study group on epidemiological markers! The content will be available on ESCMID media soon. #clinmicro

Sometimes you meet absolutely incredible bioinfo-magicians.
It was a huge privilege when @shenwei356.bsky.social
joined our group for a year on an @embl.org sabbatical.
While here, he developed a new way of aligning to
millions of bacteria, called LexicMap 1/n

Efficient sequence alignment against millions of prokaryotic genomes with LexicMap - Nature Biotechnology
LexicMap uses a fixed set of probes to efficiently query gene sequences for fast and low-memory alignment.

Our high-precision metagenomic strain caller, PHLAME, is now published in Cell Reports!! www.cell.com/cell-reports...

PHLAME works on tough sample types -- including those with coexisting strains of a species and low depth.

Researchers at @lshtm.bsky.social, led by @josebengoechea.bsky.social, will conduct a £2.2M study funded by UK MRC to investigate how Klebsiella pneumoniae silently colonises the gut before causing deadly infections. 🔬🦠

Late breaker abstracts for IMMEM conference, to be held in beautiful Portugal this September, close Friday May 23!

Something for the #ABPHM25 crowd to ponder 🤔

🧬Antibiograms have been used during outbreak investigations for decades as a surrogate for genetic relatedness of #MRSA
🦠Authors evaluate the accuracy of antibiograms in detecting transmission, using genomic epidemiology as the reference standard

📣Our latest paper is out now in mSystems: Not quite as it may seem - investigating #plasmid diversity and evolution in #Klebsiella pneumoniae at a single institution over time. A short thread 🧵 @zaminiqbal.bsky.social
Composite of the paper header showing all authors and an equation showing phylogenetic trees plus plasmids give a complex plasmid picture.

Our study also identified several uncharacterised genes that may be critical for colonisation that warrant further experimental investigation.

We also found mutations in genes that could influence how S. aureus interact with human cells or the immune system, such as in genes encoding SraP/SasA and TarS.
fcic.bsky.social
Nitrogen metabolism showed the strongest evidence of adaptation, with genes encoding sub-units of the assimilatory nitrite reductase (nasD/nirB) and urease (ureG), and a nitrogen regulatory protein (darA/pstA), showing the highest mutational enrichment.
fcic.bsky.social
We observed an excess of protein-altering mutations in metabolic genes, in the Agr system and in antibiotic targets; and showed the phenotypic effect of multiple adaptive mutations including changes in haemolytic activity, antibiotic susceptibility, and metabolite utilisation.
fcic.bsky.social
We applied a genome-wide mutation enrichment approach to identify genes in the S. aureus genome under parallel and convergent evolution that could represent signals of adaptation during colonisation.

We analysed the genomes of more than 7,000 Staphylococcus aureus isolates obtained from over 1,500 human carriers to identify genetic changes that originated in the bacteria in its host and natural environment.

Three potential PhD positions are now open for applications!
- MRCLID:
(1) integrated with my fship - AMR prevalence by age&sex
(2) long term collab. - AMR gene transfer
- Nagasaki: new collaboration comparing UK&Japan AMR rates
