Antimicrobial resistance (AMR or AR) occurs when microbes evolve mechanisms that protect them from antimicrobials, which are drugs used to treat infections. [2] This resistance affects all classes of microbes, including bacteria (antibiotic resistance), viruses (antiviral resistance), protozoa (antiprotozoal resistance), and fungi (antifungal ...
The multi-target mechanisms of aPDT avoid antimicrobial resistance, which continues to be a major global health concern. [18] [19] [20] The likelihood of developing resistance in pathogens is higher for antimicrobial strategies that have a specific target structure, following the key-lock principle, embodied in many antibiotics or antiseptics.
Antimicrobial resistance The misuse and overuse of antimicrobials in humans, animals and plants are the main drivers in the development of drug-resistant pathogens. [4] It is estimated that bacterial antimicrobial resistance (AMR) was directly responsible for 1.27 million global deaths in 2019 and contributed to 4.95 million deaths.
Knowing what genes cause antibiotic resistance -- and where they are in the body -- is critical for preventing further antibiotic resistance. Antibiotic resistance: new discovery could change the ...
Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food ...
Resistance can then spread to other microbes and to other host organisms. Antimicrobial agents can also have direct toxic effects on people and animals, including damage to kidneys, endocrine glands, liver, teeth and bones. Antimicrobial therapy is justified when the benefits outweigh these risks.
The resistome was first used to describe the resistance capabilities of bacteria preventing the effectiveness of antibiotics . [4] [5] Although antibiotics and their accompanying antibiotic resistant genes come from natural habitats, before next-generation sequencing, most studies of antibiotic resistance had been confined to the laboratory.

A variety of different bacteria - testing for antimicrobial resistance. Multidrug-resistant bacteria (MDR bacteria) are bacteria that are resistant to three or more classes of antimicrobial drugs. [1] MDR bacteria have seen an increase in prevalence in recent years [clarification needed] [2] and pose serious risks to public health.
