Happy Noodlococcus day to all those who celebrate! 🍜🧫🦠

We’re in 3 different continents now but all celebrating the 6th anniversary of the discovery of our noodle-y friend by eating some delicious noodles @prob91.bsky.social @biostan.bsky.social @gemccallum.bsky.social

🤣 I was wondering if anyone would spot that!

It was great fun writing this review with @gemccallum.bsky.social , even if our conclusions are rather scary. Lots of important pathogen evolution must be occurring outside of the infection context...

Delighted to have this review out with @jpjhall.bsky.social!

We discuss the risk of transmission of antimicrobial resistance in the hospital sink drain microbiome, highlight studies providing evidence of transfer, and consider strategies to mitigate these risks 🪠🦠

Thanks glad you enjoyed! Hahaha I think even in orbit they would still find a way to recover within a few days

Happy to finally have this out! It has been a fun side-project that we’ve been slowly working on for a while 🍜

I think it has turned out as a nice story, and demonstrates some important issues with historic taxonomic classifications in genome databases. All from investigating a contaminant! ⤵️

🚨 Very excited to finally say… 🚨

The story of Noodlococcus - the contaminant that started ContamClub - is available to read 📖🍜🦠

🍜🧬 Pan-fried noodles 🤣🤣🤣

Big shoutout to @contamclub.bsky.social for cooking up the story of Noodlococcus

We’re proud to have been part of the journey — from mystery microbe to full-genome feast 👨‍🍳🧫

A landmark paper (in the field of Kocuria rhizophila genomics).

Thanks to @gemccallum.bsky.social @biostan.bsky.social and others to get this over the line.

Have really enjoyed my day at #IOIECR25 @ineosoxford.bsky.social

Enjoyed some amazing talks and enjoyed presenting my work investigating antimicrobial resistance in the hospital sink drain microbiome

ContamClub has officially reached every continent on Earth! 🌎🌍🌏

This set of ContamMerch are with Bodil and Livvie who work at the South Georgia Heritage Trust in Antarctica - @southgeorgiaht.bsky.social

Antarctica marks 7/7 continents that ContamCalendars have been delivered to since we began 🗺️📆🦠

Special delivery from @contamclub.bsky.social (@gemccallum.bsky.social)! How cool are these socks!? 🧪🔬

#MicroSky
Two pairs of packaged socks. Left: a bright green pair with pink, yellow, green and red cartoon bacteria. Right: a white pair with a bright yellow ContamClub logo. Positioned next to a thank you card with a 3D effect pin badge of a bacterial colony.

Amazing talk by @gemccallum.bsky.social (post-doc with @jpjhall.bsky.social) on his hospital sink microbiome project, including Greg's undercover ICU sink microbiome notes and scary genomes of Pseudomonas, Aeromonas, Citrobacter.

Thanks feels good to be back!

Great to meet you! Looking forward to the workshop in Oxford

Had a great time so far at #MicroBio24 and enjoyed presenting the start of my post-doc work on the hospital sink drain microbiome today 💧🦠
