The Kocurious case of Noodlococcus: genomic insights into Kocuria rhizophila from characterisation of a laboratory contaminant
The laboratory contaminant strain Noodlococcus was named for its coccoid cells and unusual colony morphology, which resembled a pile of noodles. Along with laboratory characterisation and electron mic...

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

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 🪠🦠

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 📖🍜🦠

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 🗺️📆🦠

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.
