The antibiotic resistance genes found on the plasmids confer resistance to most of the antibiotic classes used nowadays, for example, beta-lactams, fluoroquinolones and aminoglycosides. [ 10 ] It is very common for the resistance genes or entire resistance cassettes to be re-arranged on the same plasmid or be moved to a different plasmid or ...
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.

The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
Using antibiotic-free alternatives in bone infection treatment may help decrease the use of antibiotics and thus antimicrobial resistance. [36] The bone regeneration material bioactive glass S53P4 has shown to effectively inhibit the bacterial growth of up to 50 clinically relevant bacteria including MRSA and MRSE. [258] [259] [260]
The R1 plasmid imparts multi-drug antibiotic resistance to its host bacteria. [3] It's known as a "low copy" plasmid, meaning that it exists in relatively few copies in any given bacteria. This characteristic allows the R1 plasmid to have an efficient plasmid stabilization system, that aids in stabilizing medium copy number plasmids.
HGT is responsible for much of the spread of antibiotic resistance among bacteria. [10] Gene cassettes containing antibiotic resistance genes, or other virulence factors such as exotoxins, can be transferred from cell to cell via phage, transduction , taken up from the environment, transformation , [ 11 ] or by bacterial conjugation. [ 12 ]
For example, genes conferring antibiotic resistance can be selected by growing the colonies of the library on media containing a specified antibiotic. [5] Another example is screening for enzymatic activity by incubating with a substrate that is catalyzed to a colorimetric compound that can easily be visualized.
Antibiotic resistant bacteria are able to transfer copies of DNA that code for a mechanism of resistance to other bacteria even distantly related to them, which then are also able to pass on the resistance genes, resulting in generations of antibiotics resistant bacteria. [11] This initial transfer of DNA is called horizontal gene transfer. [12]
