Industrial and agricultural chemicals exhibit antimicrobial activity against human gut bacteria in vitro - Nature Microbiology
Screening of 1,076 compounds reveals 168 chemical pollutants with inhibitory effects on gut bacteria and genetic screens indicate commonality between pollutant and antibiotic resistance.

Our paper mapping the effects of hundreds of pesticides and industrial chemicals on gut bacteria is out in @natmicrobiol.nature.com today!
Turns out many such chemicals, although labelled as 'fungicides' or similar, can inadvertently inhibit friendly gut bacteria.

Could everyday chemicals be having a toxic effect on our gut #health? 🧫🧪

150+ common substances may stifle 'good' gut bacteria in our bodies, affecting digestion and mental health.

Unexpected side-effect: how common medications clear the way for pathogens

CMFI's @lisamaierlab.bsky.social @unituebingen.bsky.social show in @nature.com: many non-antibiotics weaken the natural protective function of the intestine.

Press release: www.cmfi.uni-tuebingen.de/en/news-even...

Medications can severely disrupt this fragile balance – they eliminate beneficial bacteria and thereby promote the growth of harmful species.

It's finally out!🎉

We known that the #microbiome confers colonization resistance against #pathogens, we know that some meds 💊 affect gut microbes 🦠

So, do 💊 alter colonization resistance? It turns out that some do! If you wanna know more, check out our latest work www.nature.com/articles/s41...

IMHO, given the vast number of chemicals (and growing), and their varied chemical/biological properties, systematic in vitro studies under comparable conditions will be essential towards accelerating toxicity assessment of chemicals. My lab's 2 cents towards this: www.biorxiv.org/content/10.1...
