reduce antibiotic resistance, and; decrease unnecessary costs". [5] Decreasing the overuse of antimicrobials is expected to serve the following goals: improve patient outcomes, especially patient safety; decrease adverse drug reactions such as hypersensitivity reactions or kidney or heart damage (e.g., QT prolongation).
Antibiotic resistance can be introduced artificially into a microorganism through laboratory protocols, sometimes used as a selectable marker to examine the mechanisms of gene transfer or to identify individuals that absorbed a piece of DNA that included the resistance gene and another gene of interest. [161]
Antibiotic inactivation: bacteria create proteins that can prevent damage caused by antibiotics, they can do this in two ways. First, inactivating or modifying the antibiotic so that it can no longer interact with its target. Second, degrading the antibiotic directly.

Antibiotic Action is working to identify what opportunities exist for discovery, research, and development to ensure new antibiotics to maintain the health of the global population. [ 6 ] Antibiotic Action contributes to national and international activities such as conferences, media interviews, presentations, and displays to educate people ...
Resistance can develop through one of the three mechanisms: natural resistant ability in some types of microorganisms, a mutation in genes or receiving the resistance from another species. [5] Antibodies appear naturally due to random mutations, or more often after gradual accumulation over time, and because of abuse of antibiotics. [6]
For example, mouth bacteria can reach other parts of the body through the digestive and blood systems, and our saliva readily transfers bacteria to other people, so there are several ways for antibiotic resistant bacteria in the oral micriobiome to readily transfer their resistance genes to other, potentially pathogenic bacterial communities. [10]
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]
Antibiotic sensitivity testing is also conducted at a population level in some countries as a form of screening. [4] This is to assess the background rates of resistance to antibiotics (for example with methicillin-resistant Staphylococcus aureus), and may influence guidelines and public health measures. [4]
