Distinguishing infections requiring antibiotics from self-limiting ones is clinically challenging. In order to guide appropriate use of antibiotics and prevent the evolution and spread of antimicrobial resistance, diagnostic tests that provide clinicians with timely, actionable results are needed.
Since many R-factors contain F-plasmids, antibiotic resistance can be easily spread among a population of bacteria. [19] Also, R-factors can be taken up by "DNA pumps" in their membranes via transformation , [ 20 ] or less commonly through viral mediated transduction , [ 21 ] or via bacteriophage, although conjugation is the most common means ...
There are many factors which could be contributed to the existence and spread of MDR gram-negative bacteria such as the: overuse or misuse of existing antimicrobial agents, which has led to the development of adaptive resistance mechanisms by bacteria; a lack of responsible antimicrobial stewardship such that the use of multiple broad-spectrum ...
The spread of antimicrobial resistance – which occurs when bacteria, viruses, fungi and parasites no longer respond to medications that treat them – is an “urgent crisis” in Ukraine that ...
The resistance conferred by this gene (bla NDM-1), therefore, aids the expansion of bacteria that carry it throughout a human host, since they will face less opposition/competition from populations of antibiotic-sensitive bacteria, which will be diminished by the original antibacterial treatment.

Analyses of metagenomic sequence data are useful tools for understanding how human impact influences the spread of resistance genes. [13] An effect of the introduction of high levels of human-made antibiotics in the environment is the promotion of antibiotic resistance even in the absence of natural antibiotic production. [4]
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.
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.
