The ContamCalendar 2026 is full of microbe-related dates so you can celebrate microbiology for the whole year 📅🧫🦠

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 📆🦠🧫🍄

Look out for an exciting announcement later…. 👀 #ContamCalendar

Now published! 🎉🧫🍜 doi.org/10.1099/mgen.0…

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 🪠🦠 doi.org/10.1038/s44259…

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! ⤵️

🚨 Very excited to finally say… 🚨 The story of Noodlococcus - the contaminant that started ContamClub - is available to read 📖🍜🦠 Check it out ➡️ doi.org/10.1101/2025.0… 1/15 🧵

🍜🧬 Pan-fried noodles 🤣🤣🤣 Big shoutout to @ContamClub for cooking up the story of Noodlococcus We’re proud to have been part of the journey — from mystery microbe to full-genome feast 👨‍🍳🧫 📖 Full recipe available ➡️ biorxiv.org/content/10.110… #MicrobialMysteries #ProudServiceProvider

Have really enjoyed my day at #IOIECR25 @IneosOxford Enjoyed some amazing talks and enjoyed presenting my work investigating antimicrobial resistance in the hospital sink drain microbiome

📣 Speaker alert #IOIECR2025 @GEMcCallum from @LivUni will explore the role of the sink microbiome in spreading #AMR 💧 Join us on March 21 for our ECR conference on ‘Multidisciplinary Approaches to Tackle AMR’ ️➡️ ineosoxford.ox.ac.uk/event/ioi-earl…

Very few sets of ContamSocks left! And ContamCalendars running low! If you still want some then get them soon! 📆🦠🧫🧦 Available at ➡️ contam.club

ContamClub has officially reached every continent on Earth!🌎🌍🌏 This set of ContamCalendar and socks are with Bodil and Livvie who work at the South Georgia Heritage Trust in Antarctica Antarctica marks 7/7 continents that ContamCalendars have been delivered to since we began

‼️🚨🗓️ CONTAMCALENDAR 2025 🗓️🚨‼️ The ContamCalendar is back for another year! It’s a great one and we hope you’ll love it 🗓️🦠🧫🍄 Get yours here ➡️ contam.club ⬅️

@Cas9Bandit @PlasmidSociety Thanks!

@GEMcCallum @PlasmidSociety Cool poster!

Having fun presenting my poster at @PlasmidSociety conference in Hamamatsu, Japan 🇯🇵🦠

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 🧫✨

@SigmaAldrich @EmLBishop gotta share these #SigmaAldrichChocolate with you

It’s World Chocolate Day, and we’re excited to announce that we’re giving away our famous Sigma-Aldrich chocolate bottles!

@MicrobioSoc @dr_angharad Glad to see it has been updated on the article

@MicrobioSoc @dr_angharad "Woman becoming resistant" is a shockingly worded headline 😬 amplifying a common misconception people have about the danger of antimicrobial resistance - this makes it sound like you're only at risk of you take antibiotics long-term. Resistant infections are a threat to everyone

"It’s a very real live active issue and that’s why we’re moving away from the term silent pandemic because that makes it sound as if it isn’t having an impact, it absolutely is." Powerful quote from @dr_angharad regarding resistant UTI infections 🦠 microb.io/3V3oT0H #AMR

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 💧🦠
