A Microbiology Society branded version of a black and white cartoon of lactobacillus on a mottled pinky yellow splashy background. The bacillus is peaceful, wearing a headband and decorated with hippie style flowers, stars and peace signs. The quote is 'As they are probiotic strains, I love them from the gut of my heart! - Hiral Raval, BioGeneVersity, India.

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

A Microbiologist’s Guide to Yogurt + Instant Pot Yogurt Recipe Last year, I made 26 batches of homemade yogurt and ate probably over 350 yogurt and granola breakfasts (or some variation of that). Since I left the world of laboratory bench work, the kitchen has…

Happy #InternationalMicroorganismDay!

I'm also celebrating by eating lots of microbial foods - started my day off with some homemade yogurt (my yogurt protocol is here: microbialmenagerie.com/a-microbiolo... ), had chocolate in my granola bar, some cheese in my snack, and who knows what else.

Can't think of a better way to spend #InternationalMicroorganismDay than sampling roots in the woods! 🌳🌲

For #InternationalMicroorganismDay, I would like to highlight my favourite microbes – the main characters of my blog about evolution of multicellularity 🦠

They have something in common: all of them tell us something about the nature of multicellularity itself 🧪

🧫 Happy International Microorganism Day!

Exactly 342 years ago today, Antonie van Leeuwenhoek described a single-celled organism for the first time in a letter to the Royal Society of London. After several centuries of research, there is still much to discover! ✨

It’s #InternationalMicroorganismDay. Sometimes it’s the smallest things that have the biggest impact on the world.
For example, phytoplankton — a group of marine microbes that produce roughly 50% of the planet’s oxygen.

Let’s take a moment to appreciate these incredible organisms 🙌

🌍🔬 17 September marks the #InternationalMicroorganismDay!

The day reminds the importance of tiny life forms that make a huge impact on our world. On this day in 1683, Antonie van Leeuwenhoek first described microorganisms—opening the door to microbiology and forever changing science.

"Animalcules" | Lens on Leeuwenhoek Biologists today are seldom well-versed in the history of science. If they know anything about Leeuwenhoek, it's "animalcules", usually spoken with a little grin. So quaint!The word animalcule had a b...

On this #InternationalMicroorganismDay let’s celebrate Leeuwenhoek’s first report of microorganisms 352 years ago — but he never called them “animalcules”: in Dutch he wrote dierken/diertgens/diertjes (“small animals”); “animalcule” came from Henry Oldenburg’s English translations.

🦠🌱 Today our iPlantMicro lab joins @itqbnova.bsky.social at Santo Amaro Beach for #InternationalMicroorganismDay!

👉 Quizzes, games & demos on plant–microbe interactions
📅 Sept 17 | 🕓 16–19h | 📍 Oeiras

Come celebrate microbes with us!

A series of cartoons and quotes of the following microbes: Rhizobium, Cyanobacteria, Campylobacter, Bacillus subtilis, Acinetobacter baumannii, Klebsiella, Naegleria fowleri, Burkholderia cenocepacia, Solirubrobacter, Curvularia, Candida auris, Lactobacillus, Acidithiobacillus ferrooxidans, Aspergilius, Pestalotiopsis microspora.

It’s International Microorganism Day! We asked the Society’s Champions to tell us about their favourite microbes and, our Champion, Eliza Wolfson, has created some fun illustrations to show you a bit more of their character! @eliza-coli.bsky.social @femsmicro.org #InternationalMicroorganismDay

It's #InternationalMicroorganismDay Flashback 7 years to when I got to give a TedX talk and share my passion for My 'Crobes.

This image presents the Microbiology Galaxy Lab, a platform dedicated to One Health and ecological integrity, illustrating how it connects humans, animals, and the environment through the analysis of DNA, RNA, proteins, and metabolites using 315+ tool suites and 115+ workflows. On the left, it highlights ecosystem dynamics and biodiversity, covering areas such as microbial diversity, interactions, ecosystem modeling, strain discovery, pathway analysis, population omics, and temporal dynamics. On the right, it focuses on health and disease, addressing topics like clinical microbiota, antimicrobial resistance, pathogen profiling (viruses, bacteria, fungi, protozoa), virulence assessment, dysbiosis analysis, abundance quantification, outbreak modeling, biomarker correlation, and host interaction. The lab also emphasizes citizen science, education, and 35+ tutorials, promoting accessibility and knowledge sharing in microbiology research.

Today is #InternationalMicroorganismDay, a chance to celebrate the invisible powerhouses shaping our health and ecosystems. With @galaxyproject.bsky.social, we're proud to support global research that decodes the secrets of microbes, from deadly pathogens to life-sustaining bacteria.
