Antibiotic misuse can lead to resistance in harmless bacteria that can be shared with other bacteria, or create an opportunity for potentially harmful bacteria to replace the harmless ones. [ 37 ] Official guidelines by the American Heart Association for dental antibiotic prophylaxis call for the administration of antibiotics to prevent ...
Common forms of antibiotic misuse include excessive use of prophylactic antibiotics in travelers and failure of medical professionals to prescribe the correct dosage of antibiotics on the basis of the patient's weight and history of prior use. Other forms of misuse include failure to take the entire prescribed course of the antibiotic ...
As antibiotics inhibit bacterial infections, they are a commonly prescribed medication. Overuse of these medications over the years has contributed to reduced efficacy against certain bacteria due to antimicrobial resistance , [ 23 ] a global medical concern. [ 24 ]

Overuse of antibiotics and other antimicrobial drugs during the coronavirus pandemic is helping bacteria develop resistance that will render these important medicines ineffective over time, the ...
This means that once a gene for resistance to an antibiotic appears in a microbial community, it can then spread to other microbes in the community, potentially moving from a non-disease causing microbe to a disease-causing microbe. This process is heavily driven by the natural selection processes that happen during antibiotic use or misuse. [28]
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]
The processes by which pathogens become drug-resistant vary, but several types of antibiotic misuse, including self-medication and over-prescription of antibiotics in elderly communities have been implicated in the prevalence of drug-resistant Streptococcus pneumoniae (PRSP), Staphylococcus aureus (MRSA), and other Gram-negative bacilli.
