New research highlights the potential of random mixtures of antimicrobial peptides to significantly reduce the risk of resistance development compared to single peptides. These findings highlight the need for innovative solutions to overcome
The image illustrates the complex interactions described in your summary, and shows the complex choices that bacteriophages make between aggression and dormancy within their bacterial hosts, which are influenced by environmental cues and the health of the host.
