The ContamCalendar 2026 is full of microbe-related dates so you can celebrate microbiology for the whole year 📅🧫🦠
Greg McCallum retweeted
The ContamCalendar 2026 will likely be the final calendar we make, so we wanted it to be a great one.
The new design folds out to be A3, perfect for displaying the beautiful microbes inside 😍
Also full of microbe-related days throughout the year 📆🦠🧫🍄

Now published! 🎉🧫🍜

🚨 Very excited to finally say… 🚨
The story of Noodlococcus - the contaminant that started ContamClub - is available to read 📖🍜🦠

Delighted to have this review out with @jpjhall!
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 classifications in genome databases. All from investigating a contaminant! ⤵️

Happy Noodlococcus Day to all those who celebrate 🍜🦠
On this day in 2019, we discovered this noodle-y colony contaminating an old plate, leading to the creation of ContamClub 🧫✨
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 💧🦠

Not so fun for me but very glad to be home after 7 weeks in hospital following a 14.5 hour heart surgery.
Turns out I've had endocarditis for nearly 9 years despite years of antibiotic treatment. Hopefully the surgery and antibiotics this time will clear it 🤞🫀💊
