- Produce toxins that damage cells when reproduced
- Non pathogens (safe) bacteria can be used in labatories
- Growing Cultures: spread bacteria on a plate of agar and leave in an incubator at 25*c (at school) and 35*c ( in labatory.
- Can mutate
- White Blood Cells (WBC)
- Part of the immune system
- Injest Pathogens (Destroy)
- Produces antibodies (helps destroy
- Produces antitoxins (Poisons the pathogen
- Produces antibodies (helps destroy
- Antibiotics kill infectious bacteria (cannot destroy virus)
- Vaccination.
- can make someone immune to an antigen. the antibody will recognise it.
- Small amount of dead or inactive pathogens are injected into the body
- The antigens in the vaccine stimulates the white blood cell into making antibodies. the antibodie destroy the antigen
- You are now immune to future injections by the pathogen
- The antigens in the vaccine stimulates the white blood cell into making antibodies. the antibodie destroy the antigen
- Balance Diet
