#inktober day 13 with Drink

Microorganisms are essentials for fermentation in various products including beer, wine, kefir or kombucha.

With some friends we've already brewed our own beer, but lately I've become a huge fan of water kefir (especially with ginger).

🤤 It looks very good !

Ouuuh I actually did not think about that Banksy artwork, with the hidden shredding mechanism into the frame.

It would have been fun to use that as an inspiration for this drawing 🤔

Oh wow they look so cool 😄 !! Thank you so much for sharing this, Christoph. They do look like fusili (or rotini). Now I'm hungry and I want to know more about Rugositalea oryzae 😂

#Inktober days 11 + 12 with Sting & Shredded

Phages invade bacteria. Some bacteria fight back, cutting the phage DNA into small fragments with restriction enzymes.

These "scissors", which are part of RMS, can degrade foreign DNA, while leaving the bacteria's own DNA unharmed.

#Inktober days 8 and 9 combined - Reckless & Heavy

The reckless use of antibiotics in humans, animals and plants is the main driver in the development of antimicrobial resistance pathogens.

As one of the top global threats, AMR places a heavy burden on public health.

#inktober day 7 - Starfish

Did you know that there are bacteria, called Stella vacuolata, with a star-shape ?

When autumn begins, they're usually two different mindests:
- Those who are already looking forward to the winter holidays 🎄
- And the fall lovers 🎃

Day 4, Claw. Phages don't really have claws, but they do have tail fibres that recognise receptors on host cells and clamp on, allowing phage particles to infect their hosts. #drawtober #SciArt #Phagesky

Day 5, Moon. The physical structures of phages are often compared to the shape and landing action of a lunar lander, with tail fibres reminiscent of the landing struts, to gently settle on the surface of its host. #Drawtober #SciArt #Phagesky

Black and white ink drawing of the moon, with a giant phage on the top right that is half the width of the moon. The moon and phage are white, surrounded by a black circular background of messy, overlapping concentric circles

Day 6, Sacrifice/Cry. Individual bacterium can sacrifice themselves to prevent phages reproducing and save the rest of the bacterial community. They can also send out quorum sensing messages to warn other bacteria. #Drawtober #SciArt #Phagesky

Black and white ink cartoon of a scared, shouting bacterium with wide eyes, it has a hexagonal phage particle on its back. The bacterium has its mouth open and is shouting, in a speech bubble coming is a skull and cross bones, the skull is hexagonal and looks a bit like a phage

Lactobacillus, what a #LittleLegend !
Part of our gut and vaginal microbiome, this microbe is one of the most widely used #probiotics to treat diarrhoea and eczema. Thanks to Hiral Raval, a @microbiologysociety.org champion, for suggesting I draw this for #InternationalMicroorganismDay

#inktober day 6 with #Pierce

I am a day late, but the prompt for yesterday inspired me more than the one of today.

I could not resist drawing a specific nanoweapon called the type 6 secretion system.
In some bacteria like Vibrio cholerae, it is firing at random...

So the unexpected can happen.

#inktober day 5 with Deer

That one was tricky.

When a deer or any organism dies, microbes begin the decomposition process, returning nutrients to the soil.

They are some places where you expect murky water (or rather medium) and some places where you don't.

Poor little guy 🐟

Day 3, Soft. Soft agar is used to visualise phages - plaque assay: bacteria infected with phages are mixed with soft agar, poured over an agar plate. A bacterial lawn grows & plaques appear - as phages infect bacteria, multiply, kill & repeat to form an expanding hole. #drawtober #SciArt #Phagesky

Black and white ink drawing of an agar filled petri dish with black spots or plaques covering the surface. One of these plaques is surrounded by a circle, connected by dotted lines to a larger magnified circle showing a lawn of bacteria punctured by a circlar hole with 7 smaller bacteriophages inside

And here is our 👑 Queen B (Queen Bacterium) : E. coli

It is a ubiquitous bacterium.
It is the "lab rat" of microbiology.
And it is also a common resident of our gut.

Which bacterium would you have named as our Queen B?

#inktober day 2 with #Weave

Cyanobacteria form interwoven patterns.

The micrographs from paper by J. Cammann et al, in Nat. Comm. Physics (2024) inspired me.

Today was less about googly eyes and more about focusing on the feel of my pens. Having fun by playing with different brush and pen sizes.

Your message is so nice Mark ☺️ thank you, and sure would be happy to! And by the way, I cannot see the message @bstevensonlab.bsky.social is mentioning (I guess I was blocked)... Scammer are creative 🥲

Noémie Matthey @noemiematthey.bsky.social · 12d

It helps (and at least I could modify it on the Instagram post)! Even in my native langage I tend to do these kind of mistakes 🤭

Noémie Matthey @noemiematthey.bsky.social · 12d

😅 oh no, I did not see that and have added "one of" at the end without realising it will go from singular to plural. I cannot modify the post 🥲

It's #Inktober once more, time to grab some pen and paper. Will you join?

The first prompt is #Mustache, and this distinguished gentlebacterium is using one of its flagellum as a mustache.

The latest Preprint of the @justinecollier.bsky.social lab is out there ! I am so happy to share about my major work done on one of the two cytosine methyltransferases present in Caulobacter crescentus.

Justine Collier @justinecollier.bsky.social · Mar 24

- What are the roles of m5C bases in bacterial genomes?
- If a DNA methyltransferase is not genetically linked with a restriction enzyme (“solitary”), what is its role?
- Are “solitary” Vsr-like proteins functional?
--> Insights in our latest Preprint: doi.org/10.1101/2025...

Cytosine methylation by ScmA contributes to the fitness of Caulobacter crescentus cells naturally expressing a Vsr-like protein

While methylated cytosines are known to play important roles in eukaryotes, their significance in bacteria remains poorly understood especially when they are added on genomes by DNA methyltransferases...

I am trying to adopt a new routine on Sundays, which consists in taking some time for myself and to enjoy some creative activities including colouring our colouring book (#BacterialWorld @drsarahwettstadt.bsky.social).

For the first letter/drawing of the book, I chose to only use my fav colour!

First coloured page of the colouring book called 'coloured bacteria from A to Z' by Sarah Wettstadt and Noémie Matthey. The first bacterium is Agrobacterium tumefaciens

Zoom of the previous picture showing the Agrobacterium tumefaciens bacterium and a plant with a tumor as this bacterium can cause this disease in plant
