- More on drugs
- When plants are attacked by pathogens they produce chemicals to protect themselves which contain antibacterial effects that protect the plant against bacteria.
- Antiseptics
- Antiseptics are chemicals that destroy bacteria or stop them from growing.
- Antiseptics are used outside the body to help clean wounds and surfaces. They are used to prevent infection rather than treat it.
- Antibiotics
- Antibiotics are drugs used inside the body usually taken in the form of a pill or injection.
- They are used to treat patients who are already infected with bacteria or fungi. However antibiotics don't destroy viruses.
- There are two types of antibiotics:
- Antifungal antibiotics are used to treat fungal infections. They work by killing the fungi or stopping them from growing.
- Antibacterial antibiotics are used to treat bacterial infections. They work by killing bacteria or stopping them from growing,
- However bacteria can mutate and evolve and sometimes become resistant to an antibiotic. This means when you treat the infection only the non-resistant bacteria will be killed whereas the individual resistant bacteria will survive and reproduce.
- The population of the resistant strain will increase which could cause a serious infection not harmed by an antibiotic.
- Misuse of antibiotics (e.g. doctors over prescribing them or patients not finishing the course of their antibiotics) has increased the rate of development of resistant strains.
