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

If symptoms start, call your GP or Healthline first.

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 🕒

⚠️ What is measles (Te mate karawaka)?
A HIGHLY contagious virus that spreads through the air. People are infectious before the rash shows

Where else is ST1 hiding?

We need to start thinking about environmental & farm worker sampling to map the spread & persistence of ST1

Timeline analyses show ST1 evolving differently in people & cows

To stay ahead of emerging lineages & resistance, we need a #OneHealth lens linking human, animal, & environmental data 🌍

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

Instead we found:

🔹 Human derived ST1 = more antibiotic resistance genes #AMR

🔹 Bovine derived ST1 = a unique host-specific prophage (φSabovST1) carrying bovine leukocidins

Globally, bovine S. aureus usually belong to ST97/ST151

But in NZ 🇳🇿, ST1 dominates in humans & cattle

This unusual overlap raises big questions about possible cross-species #transmission & #evolution

#PublicHealth action worked:
🧼Hygiene issues were fixed
✅No further cases linked to the site

Genomic sequencing helped:
✔️Trace the outbreak to a single introduction
✔️Understand how it spread

#CPE isn’t just a hospital problem - it’s a community threat, but solvable

A common link kept coming up: a ready-to-eat food venue, Premises A

Environmental testing found OXA-48 #Ecoli from food handlers, some had no symptoms
One had travelled to SE Asia in 2017

The strain likely entered NZ once, then spread locally

🧵The team used #genomics to reveal community spread of #AntimicrobialResistant bacteria in New Zealand

A carbapenemase-producing E. coli was spreading
Not in hospitals, in the community

We used whole-genome sequencing to investigate & start to learn what happened

One patient, two samples

Weeks apart, E. faecium picked up vancomycin resistance

By sequencing vancomycin-susceptible strains on-site, we caught this early & avoided unnecessary, disruptive interventions #Genomics

Attending #ESCMIDGlobal & curious about community-associated CPE?
Craig Thornley is presenting today on a prolonged OXA-48-producing E. coli cluster in New Zealand, with genomic evidence supporting community & hospital transmission. See poster E0434 #ESCMIDGlobal2025

Huge thanks to the amazing team at Awanui Labs & ESR, especially Suzanne Manning (project lead) & colleagues! We need to keep pushing the boundaries of genomics in clinical settings💪 #Genomics #Microbiology #Nanopore

But challenges remain—integrating new tech into routine lab workflows takes time & investment. We discuss key enablers & barriers from a social systems perspective
March 6, 2025 at 8:50 AM
What we found:
#Nanopore sequencing enabled faster, more precise tracking of pathogens

✅Close collaboration between Awanui Labs Wellington & ESR was key

✅Barriers included #bioinformatics expertise & data infrastructure challenges
March 6, 2025 at 8:50 AM
Using Solu Genomics, a cloud-based platform, we replicated analysis of two real #NICU outbreaks (#MRSA & K. variicola). Results ready in <40 min, matched 'manual' #Bioinformatics in identifying #Outbreak clusters
February 13, 2025 at 9:30 PM
Key challenge: Many hospitals can sequence bacterial genomes but lack #Bioinformatics expertise for rapid analysis. This slows #Outbreak detection as samples/#Data is sent to reference labs, delaying #InfectionControl. Faster, decentralised #Genomics solutions are needed

#AMR is a web connecting humans, animals, & the environment🕸️
Tackling it requires a #OneHealth approach—thinking beyond just human health to protect the planet too🌍
We are all connected, & the fight against AMR starts with all of us #WAAW2024
November 23, 2024 at 8:39 AM
What about the environment?🌊
#Wastewater is a key pathway for #AMR genes. #Antibiotics excreted by humans & animals end up in sewage, & treatment plants may not remove it all.
In NZ, ESBL-producing E. coli have even been found in urban waterways
See: doi.org/10.1128/mra....
November 23, 2024 at 8:39 AM
#AMR in humans in New Zealand is a big challenge
We have high #Antibiotic dispensing rates, often for illnesses that don’t need them. This drives #AMR.
While efforts are lowering antibiotic use, NZ’s rates are still higher than many countries
See: doi.org/10.1093/jac/...
November 23, 2024 at 8:39 AM
Compared to other developed countries, New Zealand has relatively low #AMR levels in animals 🐄🐖🐓
Why? Regulations here prevent #Antibiotics from being used to promote growth in animals, & farming practices are often less intensive than factory farming elsewhere #WAAW2024

Day 6 of @who.int World #AntimicrobialAwarenessWeek: AMR isn't just a global crisis—it has local consequences🌏
It’s not just about humans. #AMR affects animals, the environment & everything in between.
To truly understand AMR, we need to see how these 3 are connected #OneHealth #WAAW🧵👇🧪 #WAAW2024

Efflux Pumps: Efflux pumps remove antibiotics from bacterial cells. This mechanism is common in Pseudomonas aeruginosa and can reduce antibiotic effectiveness #AMR #AntibioticResistance @who.int #WAAW2024 🧪
November 22, 2024 at 3:52 AM
Bacteria can acquire an #AMR gene that changes target sites. S. aureus resists penicillin by acquiring an extra copy of PBP2a, a protein that works in the presence of the #Antibiotic. This is how #MRSA (Methicillin-resistant S. aureus) becomes resistant to beta-lactam antibiotics @who.int #WAAW2024
