What is Anti-biotic?
Anti-biotics are also known as anti-bacterials, and they are drugs used to treat infections caused by bacteria. Bacteria are tiny organisms that can sometimes cause illness to humans and animals.
What is Anti-biotics used for?
An antibiotic is given for the treatment of an infection caused by bacteria. It targets bacteria, fungi and parasites. However, they are not effective against viruses. If you have an infection it is important to know whether it is caused by bacteria or a virus. Most upper respiratory tract infections, such as the common cold and sore throats are generally caused by viruses and antibiotics do not work well against these viruses.
If antibiotics are overused or used incorrectly there is a chance that the bacteria will become resistant and the antibiotic becomes less effective against that type of bacterium and new virus will be produce due to the immunity of anti-biotics.
How do Anti-biotic work?
- A bactericidal anti-biotic kills the bacteria
- A bacteriostatic stops bacteria from multiplying
