⚛️ Would today’s antibiotics still work if bacterial biology were flipped at the molecular level?

EU officials confirm a ban on Brazilian meat and dairy amid health concerns.

The EU’s ban on imports of Brazilian meat and other animal products from Thursday could be short-lived if audits later this week confirm compliance with EU standards — but European officials cautioned against expecting an “early result”.

Honestly, i'd never heard of spectinamides!

Andrew Jones and Joshua Prince at Duke University developed a model that replicates #PeripherySequestration in #biofilms by accounting for heterogeneity of antibiotic attachment sites and porosity.

In the image we show how the heterogeneous distribution of the different matrix elements and the #bacteria themselves act as barrier against #antibiotics (in red), hindering their effect.

Filamentous Phage Shields https://schaechter.asmblog.org/schaechter/2024/03/filamentous-phage-shields.html @STCmicrobeblog

Phage liquid crystalline droplets form occlusive sheaths that encapsulate and protect infectious rod-shaped #bacteria (2020) https://www.pnas.org/doi/full/10.1073/pnas.1917726117

"in #biofilms and due to the presence of #ExtracellularMatrix #polymers, Pf4 #phage particles form highly ordered yet dynamic #LiquidCrystals (tactoids) that surround the cells. Quite interestingly, these #tactoids confer on the cells an increased tolerance to #antibiotics."

Researchers at Sandia National Laboratories have combined earlier work on painless #microneedles with #nanoscale #sensors to create a wearable sensor patch capable of continuously monitoring the levels of one of these #antibiotics.

Since the outbreak of the #war in #Ukraine, certain hospital #pathogens that are #resistant to many #antibiotics have been detected much more frequently in #German #hospitals. The pathogen #Klebsiella #pneumoniae is also resistant to the reserve antibiotics of #carbapenems due to a combination of two #enzymes.

@rbreich Other major issues at work are: 1. Easy $$ on existing revenue streams protected by gov't rules (FDA, etc) that limit competition; 2. Little C-level $$ incentive to pursue risky research projects (why risk bonus $$?). This has major downstream consequences to world-wide health as evidenced by virtually no #R&D on new #antibiotics & major focus on #diseases that can be addressed by #monoclonal #antibodies, which cost much less for big Pharma to develop. Profit margins on #mAbs are HUGE.
