What are Antibiotics and what is their correct use- Antibiotics, also called antibacterials, are a type of antimicrobialdrug used in the treatment and prevention of bacterial infections. When an antibiotic is used, the non-resistant bacteria dies. However, only the resistant bacteria stay and they reproduce asexually. Thus a while new generation of bacteria is formed. The bad thing about this is that the new bacteria is resistant to antibiotics and it becomes very hard to wipe this type of bacteria out. These types of resistant cells are called superbug cella. A superbug is a strain of bacteria that has become resistant to antibiotic drugs. This superbug is formed by a change in the DNA of the bacteria or when different bacteria exchange genes with each other. AN example of a superbug is the Staphylococcus Aureus. To prevent antibiotic resistance (using antibiotics correctly)-
Take antibiotics for the entire time period that they were prescribed. Even if the symptoms have improved, it is essential to keep taking the full course of antibiotics and not stop taking them before then. Sometimes people start to feel better before all of the bacteria have been destroyed. Depending on the medical condition, antibiotics usually have to be taken for several days or sometimes even weeks before the infection clears up.
Only take antibiotics if it is absolutely necessary to do so. Antibiotics are commonly prescribed to treat medical conditions for which they are not suitable. Antibiotics are needed to treat serious bacterial infections like lung infections or meningitis. This is not the case when, for example, people who are otherwise healthy have respiratory infections such as a cold or influenza. Antibiotics will not usually help against these conditions because they only fight bacteria. Antibiotics can also have side effects, including allergic reactions, stomach and bowel problems,nausea and fungal infections. Because of these associated risks, it is important to carefully consider the advantages and disadvantages of taking antibiotics.
