Antibiotics, Volume 10, Issue 5

2021 May - 141 articles

Cover Story: Bacterial pathogens have developed mechanisms of resistance to antimicrobial agents. Multidrug-resistant pathogens are a particular public health concern. One drug resistance mechanism involves the enzymatic hydrolysis of anti-bacterial agents. Biochemical modification of antibiotics using bacterial enzymes constitutes a second resistance mechanism. Another bacterial resistance mechanism consists of the alteration of antibiotic targets that are located in the bacterial cytoplasm. A fourth mechanism encompasses the reduced permeability of bacteria to antimicrobials by the modulation of porins. A fifth mechanism entails the active transport of antimicrobial agents by integral membrane-based efflux pump systems. This review article summarizes these resistance mechanisms and provides directions for future investigation. View this paper
