| The word "antibiotic" derives from the Greek anti denoting "against" and bios denoting "life" (a bacterium is a life form). Antibiotics are effective medicines prescribed to treat bacterial infections. If taken in the right way, antibiotics can save lives. They either fight off bacteria completely or impede their reproduction. Your body's natural defenses can usually take it from there. Most antibiotics have 2 names, the trade name created by the manufacturer, and a generic name based on chemical characteristics of antibiotics. Antibiotics do not kill viral infections, such as colds, flu, most coughs and bronchitis, sore throats unless caused by streptococci. A broad-spectrum antibiotic can be taken to fight off a wide range of infections. A narrow-spectrum antibiotic is only efficient against several types of microorganisms. There are antibiotics that can kill off aerobic bacteria, whereas others work against anaerobic bacteria. Aerobic bacteria need oxygen, whereas anaerobic bacteria do not. Antibiotics may be given in advance, to forestall an infection, in particular prior to operation. This is called 'prophylactic' use of antibiotics. They are normally taken before bowel and orthopaedic surgery. Antibiotics can bring on more harm than good, if they are not used in the right way. Widespread use and misuse in people over time have jeopardized antibiotics' power to fight off microbes. Today, nearly all bacteria are antibitocs-resistant, so that more lately developed antibiotics are sometimes needed to fight infections once easily treated. Antibiotics can also lead to complications, for example diarrhoea and vaginal yeast infections. When you take antibiotics, follow the instructions. Your dosage has been measured to kill bacteria throughout the course of the disease. Therefore, if you do not coating, you may find yourself at the risk of leaving enough bacteria in your system to re-start the infection - even after you are feeling good. The leftover medicine will be insufficient to fight off the bugs the next time, and it may even make them resistant. |
