The team focused on amino acid proteins called peptides generated by the gut bacteria, which have often been used to create antibiotics. In total, they assessed the potential antibiotic utility of ...

Traditional antibiotics drive bacteria toward drug resistance, so scientists are looking to viruses, CRISPR, designer molecules and protein swords for better treatments.

This study first examined data from 1,663,701 patients aged older than 18 years between July 1984 and December 2023 that were prescribed penicillin as well as an additional antibiotic. The ...
