Beta-lactam antibiotics are the cornerstone of our antibiotic armamentarium. By inhibiting bacterial cell wall synthesis, they are highly effective against Gram-positive and Gram-negative bacteria. Unfortunately, bacteria have evolved sophisticated resistance mechanisms to combat the lethal effects of beta-lactam antibiotics.

Using recently developed predictive guidelines for compound accumulation in Escherichia coli, we have converted the antibiotic Ribocil C, which targets the flavin mononucleotide (FMN) riboswitch, from a compound lacking whole-cell activity against wild-type GN pathogens into a compound that accumulates to a high level in E. coli, is effective against Gram-negative clinical isolates, and has efficacy in mouse models of GN infections.

Minimizing antibiotic use when possible and giving shortest possible durations of therapy for proven infections is key. Gram-negative pathogens are gaining ground against antibiotics as fewer new agents are being developed to combat antimicrobial resistance (AMR). 1 Antibiotics are one of medicine’s greatest achievements, yet their misuse has ...

Antibiotics like vancomycin and other b-lactam antibiotics target peptidoglycan, a substance in the bacteria cell wall. However, these antibiotics are ineffective against gram-negative bacteria because the slime layer in the outer membrane hide the antigens and do not allow these antibiotics to penetrate it.

The outer membrane of Gram-negative bacteria plays an important role that is related to resistance to many antibiotics that are highly effective against Gram-positive bacteria, e.g. macrolides, novobiocin, rifamycin, lincomycin, clindamycin and fusidic acid.
It's very important to realize that we do not need to give antibiotics to patients who are isolated with COVID-19 in their homes, because they have mild disease.
