Bacteria

Bacteria are tiny one-cell micro-organisms.

They can reproduce inside or outside their hosts.

Their hosts are people, animals and plants.

Like other germs, bacteria don’t make their own food.

There bad bacteria and good bacteria.

Bad bacteria can cause eye infection, cholera, tuberculosis (TB) and others.

A bacteria named Salmonella can caused something like a very bad food poisoning.

They are sometimes found in eggs and peanut butter.

There are very dangerous bacteria named super bugs.

A type of super bug

Super-bugs are very difficult to be killed.

Super-bugs are usually found in hospital.

My grandfather was infected by super bugs when he was sick in UKMSC a few years ago.

The doctors said that I cannot visit him at that time because super bugs are even more dangerous to kids.

Good bacteria in our tummy keep us healthy by helping us to use nutrients from the food we eat.

We use good bacteria for making cheese and yoghurt.

A type of bacteria used to make cheese

Cheese and yoghurt are healthy food.

We also use good bacteria to make medicines and vaccines (vak-seens).

Medicines and vaccines help us to fight germs so that we can be healthy.

Uncle Azahar taught me that some bacteria can be bad bacteria if they are moved from their original site.
