What are the causes of antibiotics resistance?
Antibiotics resistance occurs when microorganisms such as bacteria develop the ability to withstand the effects of antibiotics either partially or completely. Bacteria can gain this resistance to antibiotics directly through natural phenomena or indirectly through environmental stressors. One such stressor, abuse of antibiotics by medical workers and patients, leads to increased prevalence of resistant bacteria.
microorganisms show resistance to antibiotics if they have acquired the ability through evolutionary agents such as natural selection, specifically transmission between bacteria of changed genes that are responsible for antibiotics resistance. Genetic variants that already exist in resistant bacteria can be transferred to the offspring of these mutated bacteria. Random genetic mutations can also be introduced through the horizontal gene transfer, a gene effect including bacteria that are not descendants of themselves. Bacteria that carry more than one reThe Zistant gene is considered multi-resistant and is commonly referred to as superbugs. When bacteria are exposed to antibiotics, normal bacteria die and leave bacteria resistant to antibiotics, which can then grow rapidly and appear as a dominant trunk.
The extensive use of antibiotics in medicine has been associated with an increasing number of cases of antibiotics resistance. Adverse or unnecessary regulations of antibiotics doctors and improper use of antibiotics in patients who do not use them as prescribed or who insist on the use of antibiotics for nebacterial infection, are the main causes of antibiotics resistance. Patients who do not complete the whole course of antibiotics, as prescribed, increase the chances of resistance to antibiotics. Antibiotics only fight with bacterial infections and doctors who do not diagnose viral infections or other nebacterial infections and prescribesThe antibiotic also promotes the likelihood of the appearance of a resistant bacteria strain. Such factors that fall within the extent of human medicine have significantly contributed to the formation and persistence of resistant bacteria and life -threatening superbugs.
antibiotics are not limited to human use and can be found in animals that are designed for human consumption or that come into contact with humans. Animal feed may include antibiotics to support growth in animals and such practices increase the risk of human exposure to superbugs and other resistance to antibiotics. Administration of antibiotics to animals that lack the disease further promotes the spread of resistant bacteria. The chances of spreading the tension of bacteria with resistance to antibiotics are increased when people consume affected meat, especially if it is raw or insufficiently cooked, or is close to close contact with animals carrying resistant bacteria.
