Bacteria are biological agents that are susceptible to antibiotics but can develop resistance through genetic mutations or acquiring resistance genes from other bacteria. Overuse or misuse of antibiotics can accelerate this process, leading to the development of drug-resistant bacterial strains.
Bacteria
These are the bacteria.Bacteria are (usually) single-celled microorganisms consisting of cytoplasm surrounded by a cell wall. They contain genes, but these are not in a nucleus separated from the cytoplasm as is the case in many other organisms eg animals and plants.Bacteria may be killed by antibiotics but can develop resistance to the anitbiotic. This ocurs when antibiotics are used unnecessarily or a course of tablets is not finished. Any individual bacterial cells which can resist the antibiotic will survive and reproduce, passing ion the genes for resistance to their offspring. The resistant individuals will therefore become more common. This is an example of how natural selection works.See http://en.wikipedia.org/wiki/Antibiotic_resistance
Antibiotic resistance: Bacteria can develop resistance to antibiotics through genetic mutations, making the drugs less effective in treating infections. Pesticide resistance: Insects can develop resistance to pesticides over time, reducing the effectiveness of pest management strategies in agriculture.
Biological resistance refers to the body's natural ability to repel attacks by biotic agents such as pathogens or toxins. It could also mean the genetic ability to survive lethal doses of biocides.
Bacterial populations can develop drug resistance through mutations that make them less susceptible to antibiotics. They can also acquire resistance genes from other bacteria through mechanisms like conjugation, transformation, or transduction, allowing them to share resistance traits. This exchange of genetic material can lead to the rapid spread of drug resistance among bacterial populations.
Individual pathogens can develop resistance to antimicrobial drugs through several mechanisms. These include acquiring genes that code for drug resistance, mutations that render the drug targets less susceptible to the drugs, and the ability to pump out or destroy the drugs. These adaptations occur through genetic changes that give the pathogens a survival advantage and allow them to evade the action of the drugs.
