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).
The U.S. Government Antimicrobial Resistance (AMR) Challenge, initiated in 2018, is a global effort that calls upon pharmaceutical and health insurance companies, food animal producers and purchasers, medical professionals, government health officials, and industry leaders worldwide to collaborate in combating antibiotic resistance.
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
Farmers typically use antibiotics in animal feed to improve growth rates and prevent infections. However, this is illogical as antibiotics are used to treat infections and not prevent infections. 80% of antibiotic use in the U.S. is for agricultural purposes and about 70% of these are medically important.

In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant. [1]
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 ...
The empirical use of broad-spectrum antibiotics increases, by selection, the prevalence of bacteria resistant to several antibiotics. However, the delay and expense that would be required to perform definitive species identification in every single clinical case are not affordable, so some degree of trade-off is accepted on the principle of the ...
The resistance can vary from moderate to severe. Enterobacteriaceae are common commensals and infectious agents. Experts fear CRE as the new "superbug". [1] The bacteria can kill up to half of patients who get bloodstream infections. [2] Tom Frieden, former head of the Centers for Disease Control and Prevention has referred to CRE as "nightmare ...
