Global Pneumococcal Sequencing Project @globalpneumoseq.bsky.social · 15d

Why it matters:
📊 Genomic surveillance is vital for tracking serotypes, AMR, and informing vaccines.
⚡️ GPS Pipeline makes this possible in a reproducible, scalable, and portable way.

Potential new pbp substitutions that link to beta-lactam resistance in S pneumoniae

Global Pneumococcal Sequencing Project @globalpneumoseq.bsky.social · 17d

By linking their shifts in the phenotypic map above with the amino acid changes in PBP protein, we could pinpoint particular substitutions and its impact on resistance.

Some pneumococcal lineages are more resistance to beta-lactams - coincides with our observations in the #GPS_project

AMR cartography to show the MIC values of multiple antibiotics

Global Pneumococcal Sequencing Project @globalpneumoseq.bsky.social · 17d

[New pre-print🚨] When a single genotype (pbp) confer resistance (penicillin, amoxicillin, cephalosporins) to multiple antibiotics, how do we make sense of genetic changes and their impact on AMR?

A new concept - AMR cartography is invented.

Global Pneumococcal Sequencing Project @globalpneumoseq.bsky.social · 21d

Our findings show how dense population, high vaccine uptake, widespread antibiotic use, and mobility shape a distinct pneumococcal landscape. Sustained genomic surveillance is essential to detect emerging threats, guide vaccine strategy for the ageing population, and monitor AMR in the post-PCV era.

Global Pneumococcal Sequencing Project @globalpneumoseq.bsky.social · 21d

Key findings:
1) Increase in elderly IPD post-PCV13
2) Rapid post-vaccine emergence of GPSC9-serotype 15A.
2) Frequent capsular switching in GPSC6
4) GPSC1-19A are persistent after PCV13
