A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. Antibiotic use in livestock is the use of antibiotics for any purpose in the husbandry of livestock, which includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment ...
While antimicrobial resistance does occur naturally over time, the use of antimicrobial agents in a variety of settings both within the healthcare industry and outside of has led to antimicrobial resistance becoming increasingly more prevalent. [23]
In a literature review conducted by the Review of Antimicrobial Resistance 100 out of 139 studies found evidence of a link between antibiotic use in animals and antibiotic resistance in consumers. [6] When a gram-negative bacterial infection is suspected in a patient, one of the first-line options for treatment is in the fluoroquinolone family.
Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition. [1] The term is used in the context of resistance that pathogens or cancers have "acquired", that is, resistance has evolved.
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. [4]
Select an antimicrobial which targets the specific organism, rather than relying on a broad-spectrum antimicrobial; Complete an appropriate duration of antimicrobial treatment (not too short and not too long) Use the correct dose for eradication; subtherapeutic dosing is associated with resistance, as demonstrated in food animals.
Cross-resistance can take place between compounds that are chemically similar, like antibiotics within similar and different classes. [9] That said, structural similarity is a weak predictor of antibiotic resistance, and does not predict antibiotic resistance at all when aminoglycosides are disregarded in the comparison. [10]
Resistance can then spread to other microbes and to other host organisms. Antimicrobial agents can also have direct toxic effects on people and animals, including damage to kidneys, endocrine glands, liver, teeth and bones. Antimicrobial therapy is justified when the benefits outweigh these risks.
