The bacterial staining is minimally inhibited by the presence of serum proteins or even blood serum. Mechanistic studies indicate that our peptide probes bind colistin-resistant bacteria primarily by targeting PE-modified lipids. However, some species-specific features of the cell surface can also contribute to the peptides' association to bacterial cells. Further elucidation of such cell surface features may give molecular probes with improved species and strain specificity, which will enable bacterial infection diagnosis with high precision.The need for new antimicrobial therapies is evident, especially to reduce antimicrobial resistance and minimize deleterious effects on gut microbiota. However, although diverse studies discuss the adverse effects of broad-spectrum antibiotics on the microbiome ecology, targeted interventions that could solve this problem have often been overlooked. The impact of antibiotics on gut microbiota homeostasis is alarming, compromising its microbial community and leading to changes in host health. Recent studies have shown that these impacts can be transient or permanent, causing irreversible damage to gut microbiota. The responses to and changes in the gut microbial community arising from antibiotic treatment are related to its duration, the number of doses, antibiotic class, host age, genetic susceptibility, and lifestyle. In contrast, each individual's native microbiota can also affect the response to treatment as well as respond differently to antibiotic treatment. In this context, the current challenge is to promote the growth of potentially beneficial microorganisms and to reduce the proportion of microorganisms that cause dysbiosis, thus contributing to an improvement in the patient's health.
