Resolving plasmid-encoded carbapenem resistance dynamics and reservoirs in a hospital setting through nanopore sequencing The growing resistance of Enterobacterales to last-resort antibiotics such as carbapenems puts a significant burden on healthcare systems, also due to plasmids driving a rapid spread of carbapenem res...

Thanks @pursuelearning.net! This is built on the ‘quiet’ everyday work of folks across PHF Science, diagnostic labs & IPC teams in @healthnz.govt.nz

They deliver services, catch patterns & make sure these ‘routine’ samples don’t slip through. We’re fortunate to apply genomics to help tell the story

The uncomfortable question this paper leaves open...

👉 How many other high-risk #AntimicrobialResistance genes are carried on tiny plasmids we’re not even watching for yet?

What didn’t work (at first)

Standard bacterial WGS told us about related cases, but not how the resistance was moving

It took complete genomes to see that this plasmid is global, stable, & quietly successful

What we did👇
We rebuilt bacterial #Genomes end-to-end, including plasmids

Then we compared that tiny col plasmid to hundreds of col plasmids from around the world

Patterns emerged that standard methods miss

Why this matters🤔

Small plasmids are 'easy' for bacteria to carry. They don’t slow growth & aren't dropped when antibiotics aren’t used

#AMR genes can sit waiting

When antibiotic use rises, selection pressure flips the switch & AMR bacteria can spread fast

But in these New Zealand cases, the OXA-48 gene wasn’t on a massive #plasmid

The gene was OXA-48

It encodes an enzyme that can break carbapenems... which are #Antibiotics we keep for when nothing else works

Typically, this gene spreads on big, obvious DNA mobile elements known as plasmids

You’re describing diagnostics not surveillance. MALDI/LFIA give ID & phenotype. They don’t produce genomes for cross-site comparison. WGS links cases & supports regional/global surveillance- info used to target isolation, cleaning & screening. Phenotype guides treatment; genotype informs prevention👋

Rapid tests detect. They don’t link cases, map plasmids, or resolve transmission. WGS does & feeds harmonised, shareable genomes into cross-institution & global #PublicHealth surveillance. Lateral-flow assays or MALDI-TOF don’t produce genomic data, so they cannot serve that role

Genomics isn’t just solving #Outbreaks, it’s stopping them before they escalate

HOT take from @natrevmicro.nature.com: If you only sequence #MDR outbreaks, you’re already late. Consider susceptible strains & #Plasmids

PAHO infographic. Title: “Measles is very contagious.” Diagram shows one person transmitting to many. Text states one person can infect 9 of 10 unvaccinated people.

Highest risk: unvaccinated people, babies under 12 months, pregnant people, & those with weakened immunity. Complications can be serious 👶 🤰 🧪

CDC purple infographic. Title: “Measles. It isn’t just a little rash”. Symptoms listed: high fever, cough, runny nose, red watery eyes, rash 3–5 days later. Risks: pneumonia, brain swelling, death. Stats shown: ~1 in 5 hospitalised; ~1 in 20 children get pneumonia; ~1 in 1,000 develop encephalitis; 1–3 in 1,000 deaths. Notes rare long-term SSPE years later. Closing message: protect children with MMR vaccine; talk to a healthcare provider.

Symptoms to watch: fever (≥38°C), cough, runny nose, sore red eyes, then a rash.

If symptoms start, call your GP or Healthline first.

WHO and CDC graphic. A child sneezes into a tissue with virus icons around. Text says measles spreads easily when an infected person breathes, coughs, or sneezes.

How can #measles spread?
Breathe the same air as an infectious person & you can catch it. The virus can linger in the air or on surfaces for up to 2 hours 🕒

We expected human & bovine derived ST1 to be genomically ‘similar’

Instead we found:
