virus: HIV potential AIDS - TMV
bacteria: salmonella - agrobacterium
fungi: athletes foot - rose black spot
protists: malria - downy mildew

direct contact: sexual or not sexual contact e.g. shaking hands
water: dirty water can transmit diease
air: tiny dropelts from e.g. sneeze can infect air
food prep: undercooked/reheated food can cause bacterial disease/food poison
vector: any organism tha

1 of 7

TMV: through contact.
infects chlorplasts of plant leaves changing color from green to yellow or white in a mosaic. Can crinkle the leaves

Reduces growth and ability to photsynthesise
NO CURE (VIRUS)

HIV/AIDS: through sexual/ injections
flu like symptoms
no cure
VIRUS

MEASLES: Air bourne through droplets
can cause infertility
VIRUS

2 of 7

BACTERIAL:
GONEREAH: std, green/yelloe discharge, contraception is a prevention, treated by antibiotics

SALMONELLA: food poison, vomit+dioreah etc. poultry is vaccinated to prevent it,

PROTIST

MALARIA: mosquitos spread it, fever+sweat+chills etc, no vaccination, prevention is stopping bites,

human defecnce systems:

skin: forms scabs and clots blood disaloowing infection or micrororgansims to enter

nose: internal hairs, muscus produced trapping pathogens before they can eneter lungs

bronchi and trahea: clila runs through. waft mucus up to throat where it is allowed into stomach.

stomach: acid breaks down food and can kill any pathogens that have attatched themself to the mucs in the airways

4 of 7

PHAGOCYTES:
engulf any nearby pathogens
non specific becaus they do this to any pathogen enterin ghte body

LYMPHOCYTES:
recognise antigens
produce antibodies
antibodies bind to pathogens so the phagocytes can engulf them

herd iummunity

The majority of the population are not vaccinated against a specific disease, however, a few people are ill and contagious. This can develop easily into a mass infection because the majority of the population are not vaccinated.
Most of the population are

6 of 7

antibiotics: slow down growth of bacteria

can be overused and create immunityt to them
failure to complete course

The drugs are tested using computer models and human cells grown in the laboratory. This allows the efficacy and possible side effects to be tested. Many substances fail this first test of a preclinical drug trial because they damage cells or do not seem
