bacteria are small living cells

1)bacteria are very small cells 1/100th the size of your body cell which can reproduce rapidly inside your body

2) they can make you feel ill by producing toxins that dangres your cells and tissue

viruses are not cells they're much smaller

3) ive inside cells and replicate themselves using cells machinery ro produce many copies of themselves

5) this well damage is what makes you feel ill

1) viruses are not cells they are tiny about 1/100th the size of a bacterium

protists

lots of different types they all eukaryotes

some are parasites live on inside other organisms and can cause damage

fungi

some have a body which is made up of hyphae

hyphae can grow and penetrate human skin and the surface of plants causing diseases

some are single celled

the hyphae can produce spores which can be spread to others plants and animals.

spared in different ways

air

direct contact

water

some pathogens can be picked up by drinking or bathing in dirty water

cholera is a bacteria infected that is spread by drinking water

some air born pathogens are carried in the air is droplets produced when you cough or sneeze

pathogens can be carried in the air and then be breathed in

Some pathogens can be picked up by touching contaminated surfaces, including the skin.

e.g athletes foot is a fungus which makes skin itch and flake off. It's most commonly spread by touching the same things as an infected person, e.g. shower floors and towels
