antibiotic resistance

• ANTIBIOTIC RESISTANCE:

  bacteria enters the body.

  person takes antibiotics.

  random mutations occur.

  bacteria becomes less affected by the antibiotic.

  the surviving bacteria not killed by the antibiotic form a new colony called an antibiotic resistant strain.

  The bacteria infect other people.

  the other person takes a different antibiotic.

  sometimes the bacteria could develop resistance to this too.

  This resistant bacteria is called a superbug.
• MRSA is a common superbug that can spread in hospitals easily. It is resistant to most antibiotics. Because of this, it can be fatal.
• antibiotic resistance is very rare
• because there are many types of antibiotics, resistance is sure to arise
• antibiotics are sometimes given unnecessarily to humans who have a mild bacterial infection or a viral infection. Antibiotics are not effective against viruses.
• antibiotics are commonly given to animals to help them grow faster or not get ill, however this can lead to more antibiotic resistance
• to prevent antibiotic resistance, we need to limit the use of antibiotics
