6.2 Pathogens Flashcards
Influenza transmission
Droplet Infection
Direct contact with virus
Zoonotic Infection
Direct contact with animal waste
Influenza mode of infection
Infects ciliated epithelial cells
Viral RNA takes over cell
Cell produces new virus particles
Cell lyses
Influenza Pathogenic Effects
Headache
Sore Throat
Coughing
Influenza treatment
Antiviral Medication
Antibiotics
Painkillers
Stem Rust Fungus Transmission
Wind carries spores from infected plants
Stem Rust Fungus Mode of Infection
Spore germinates on plant
Produces hyphae which enter the plant through stomata
Hyphae grows into mycelium
which surrounds all tiisues in the plant + produces enzymes
causes cellulase to absorb nutrients in the fungus
Stem Rust Fungus Pathogenic Effects
Weakened stem
Water loss as plant can’t control transpiration
Pustules on epidermis
Stem Rust Fungus treatment
Reducing application of fertilisers
Bigger spaces between plants to reduce moisture + an increase in distance for spore to travel
Malaria Transmisssion
Vector of the female Anopheles mosquito
Malaria Mode of Infection
Parasite transmitted via mosquito
Travels to liver
Infects red blood cells
Reproduces asexually in erythrocytes of humans
Reproduces sexually in mosquitos
Malaria Pathogenic Effects
Sweating
Shaking
Muscle Pains
Malaria Treatment
Insect Repellent
Avoid Stagnant Water
Proper disposal of Sewage
Ethical Implications of Endemic Diseases
Informed consent may be difficult
Spraying mosquitos with insecticides will affect other organisms
Money spent on vaccones could be spent on education
Social Implications of Endemic Diseases
Vaccines need to become accepted
Social changes to reduce infection are difficult to bring about
Economic Implications of Endemic Diseases
Treatment, control + prevention of endemic diseases is expensive
malnutrition may be more of a threat to human life than malaria
