Mechanisms of Antibiotics Resistance in Bacteria

Abstract

One kind of medication resistance that occurs when a microbe can withstand exposure to an antibiotic is known as antibiotic resistance. Antimicrobial drug resistance in bacteria can arise from spontaneous or induced genetic mutations; nevertheless, genes causing resistance can be horizontally transferred between bacteria by conjugation, transduction, or transformation. Therefore, a gene that develops resistance to antibiotics through natural selection might be spread. Antibiotic resistance is subsequently selected for by evolutionary stressors like antibiotic exposure. Plasmids have a large number of antibiotic resistance genes, which aid in their transmission. A bacteria is referred to as multidrug resistant (MDR), superbug, or super bacterium if it possesses several resistance genes. In the modern world, resistance is growing, which has led to a significant public health crisis. The sharp increase in antibiotic use is the main factor causing antibiotic-resistant bacteria to arise and spread. This pattern, which attributes infectious disease causation to microbial pathogens, is a reflection of the global medicalization of society. Antibiotics offer recovery. This, together with the fact that they are generally easy to use, have brief treatment needs, and are freely available without a prescription in many areas of the world, creates a demand that is being filled by a rising number of generic medications made in developing market countries. The animal welfare industry has seen a similar increase in consumption, raising worries about the spread of antibiotic resistance up the food chain. Unpredictable disasters that cause population growth, mass migration, starvation, and contaminated water supplies also pose a hazard to human health and aid in the spread of antibiotic-resistant organisms. State-to-state conflicts, environmental deterioration, and climate change can create conditions that encourage the spread of infectious diseases and perhaps elevate antibiotic resistance.
