Pathogens. Describe:
1. Bacteria
2. Viruses
3. Protists
4. Fungi
In terms of What they Are and Do | 1. Stupidly small Cells, 100 Times smaller than your Body Cells, which can also Reproduce Quickly [Asexual] They can make you Ill by making Poisons that Affects Cells and Tissues
2. NOT CELLS; very Tiny, 100 times small than a Bacterium. What they do is Replicate Inside the Infected Cells, which then Burst. This releases a Outbreak of Viruses
3. Eukaryotic Single Cells that don't have a Determined Size. They make Diseases that are Parasites
4. Fungi can be Single Celled; others can have a Body, made from Hyphae. Said Hyphae can grow into Human Skin and Plant Surfaces, starting Diseases. Spores can also be Grown spreading to more Organisms |
How can Communicable Diseases Spread through Water? | -Pathogens can be found inside Drinking or Bathing Dirty Water [Polluted River]
-Cholera, a Bacterial Infection, can cause Diarrhoea and Dehydration. |
How can Communicable Diseases Spread through Air? | -Pathogens can be Taken with the Air
-Erysiphe Graminis is a Fungus, that makes White, Fluffy Patches appear on Leaves of Barley Plants. This affected Photosynthesis. Thjis is spread via Spores that are Blown between said Plants by the Wind
-Airborne Pathogens, carried in Droplets of Cough and Sneeze, and be Breathed in. Flu spreads from that |
How can Communicable Diseases Spread through Contact? | -Pathogens can literally be Picked up from Contaminated Surfaces
-Tobacco Mosaic is a Disease caused by a Virus [TMV] which affects Photosynthesis of Plants by Discolouring the Plant
-It Spreads when the Infected Leaves rub against Healthy Leaves
-Athlete's Foot is a Fungus, making Skin Itch and Flake off. Happens because its touching the same Things as an Infected Person, Towels. |
How can Communicable Diseases Spread through Body Fluids? | -Pathogens can be spread via Blood, Breast Milk and Semen - All Body Fluids
-HIV, a Virus that can Affect the Immune System and make it weaker to other Diseases, can be Exchanged during Sex [Body Fluids] |
How can Communicable Diseases Spread through Animal Vectors? | -Vectors are just Animals that spread Diseases
-Malaria is done by a Protist, and Malaria usually stay with Mosquitoes, a Parasite.
-When the Mosquito feeds on an Animal, it can infect the Animal with Malaria as its Inserted in. Malaria is Fatal |
How can Communicable Diseases Spread through Soil? | -Pathogens can Chill in the Soil, meaning Plants that grow in the Infected Soils will also be Infected
-Agrobacterium Tumefacines, a Bacteria that lives in Soils and Roots of Plants will cause Crown Gall Disease, which will Damage the Water Flow making the Plant Weaker. This is Fatal for the Plant |
How can Communicable Diseases Spread through Food? | -Pathogens can enter you through Consumption of Contaminated Food
-Salmonella is found in some Foods, that can Infect you if Consumed. |
