Researchers from #Germany have isolated a novel #antibiotic named saarvienin A. The glycopeptide was obtained from an Amycolatopsis strain by Rolf Müller and his team and was described in the journal Angewandte Chemie. With a completely novel structure, it exhibits excellent antibiotic activity against Gram-positive bacteria and can overcome vancomycin resistance. However, cytotoxicity against eukaryotic cells has also been observed.

Nearly 25% of this list about "#Health 'Lies'" is #AMR ranting. 🤣

Extreme diversity of phage amplification rates and phage–antibiotic interactions revealed by PHORCE

PHORCE is a new high-throughput method that enables precise measurement of lytic phage amplification rates in bacterial populations. Using PHORCE, this study reveals broad phenotypic diversity among E. coli and P. aeruginosa phages and shows that phage-antibiotic interactions are primarily determined by the antibiotic.

This is so cool! Literally the project my students are doing in #microbiology this quarter, and it yielded a new CLASS of #antibiotic, which the world badly needs. #science #GoodNews https://healthsci.mcmaster.ca/a-breakthrough-moment-mcmaster-researchers-discover-new-class-of-antibiotics/
The last time a new class of antibiotics reached the market was nearly three decades ago—but that could soon change, thanks to a discovery by researchers at McMaster University.

New antibiotic for multidrug resistant superbug

Researchers from the universities in Konstanz and Vienna discover a new class of antibiotic that selectively targets Neisseria gonorrhoeae, the bacterium that causes gonorrhoea. These substances trigger a self-destruction program, which also operates in multi-resistant variants of the pathogen. The novel findings are published in the current issue of Nature Microbiology.

Antibiotics cause damage of gut microbiome of human babies, which in turn reduces #vaccine efficacy. In the mouse model, vaccine efficacy after #antibiotic treatment can be restored with #probiotics. https://www.nature.com/articles/s41586-025-08796-4
Bifidobacteria support optimal infant vaccine responses - Nature

Neonatal antibiotic use is shown to reduce immune response to infant vaccines, accompanied by reduced abundance of Bifidobacteria in the gut microbiota, with experiments in mice indicating that probiotic therapy could be beneficial.

New #antibiotic that kills #drugresistant #bacteria discovered in technician’s #garden
It targets bacteria’s protein-making factory, the #ribosome, in a way that other antibiotic drugs don’t. Ribosome is an attractive antibiotic target because bacteria don’t easily develop resistance to #drugs targeting the structure. In studies, #lariocidin slowed the growth of a range of common bacterial #pathogens, including many multidrug-resistant strains.
