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 📆🦠🧫🍄

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

13/15 The oldest strain in the K. pseudorhizophila strain was first isolated by William A. Randall in a 1949 publication, so we suggest that an appropriate species name for the K. pseudorhizophila clade would be Kocuria randallii

12/15 The lack of indication that these strains are genetically distinct from the reference genome for K. rhizophila may lead to conflicting results and inaccurate conclusions
For example, this product is derived from a strain present in the K. pseudorhizophila clade ⤵️

10/15 Pan-fried noodles: pangenomic analysis of K. rhizophila showed clear clade-specific distinctions, adding weight to the argument that they should be separate species 🍳

9/15 All other Kocuria species had inter-species ANI values inline with the typical threshold of >95%. Splitting the two clades into separate species would maintain taxonomic consistency within the genus

7/15 When comparing all K. rhizophila genomes, we found that they clustered into two distinct clades 🤔
This was also indicated when calculating average nucleotide identities (ANIs), a common way of comparing genetic similarity (see heatmap)

4/15 From the Noodlococcus genome, we identified regions involved in replication 🔂, carotenoid synthesis 🟡 (the set of genes producing the distinctive yellow pigment!), and genome defence 🛡️ (CRISPR-Cas), and discovered four novel mobile elements (ISKrh4-7) 🧬

2/15 On August 9th 2019, we found a contaminant resembling a pile of noodles on an old BHI plate
After microscopy revealed it was a Gram-positive coccus, we named it Noodlococcus 🦠🍜

Any idea what this cool little contaminant is from @aislingbrady.bsky.social’s LB +gentamicin plate?
