The 20 questions

  1. Which symptoms are characteristic of salmonella food poisoning?

    • Yellow discharge and pain
    • Fever and cramps
    • Cough and sore throat
    • Rash and joint pain

  2. What is the primary method of transmission for salmonella?

    • Ingested in food
    • Sexual contact
    • Airborne droplets
    • Direct skin contact

  3. How is the spread of salmonella controlled in UK poultry?

    • Antibiotic sprays
    • Poultry vaccination
    • Removing infected leaves
    • Barbed wire fences

  4. Which symptom is a key clinical indicator of gonorrhoea?

    • Red skin rash
    • Yellow or green discharge
    • Persistent dry cough
    • Black leaf spots

  5. How is gonorrhoea spread?

    • Sexual contact
    • Contaminated water
    • Soil contact
    • Droplets from sneezes

  6. Which antibiotic once easily treated gonorrhoea?

    • A fungicide
    • Penicillin
    • A measles vaccine
    • Statins

  7. What caused penicillin to become ineffective against many gonorrhoea infections?

    • Stronger toxins
    • Cell wall loss
    • Viral mutation
    • Resistant strains

  8. Which contraceptive method helps prevent the transmission of gonorrhoea?

    • Condoms
    • Coital withdrawal
    • Surgical sterilisation
    • Oral contraceptive pill

  9. A patient presents with severe diarrhoea and fever after eating undercooked poultry. Name the pathogen.

    • HIV
    • Rose black spot
    • Tobacco mosaic virus
    • Salmonella

  10. What is the main purpose of vaccinating farm poultry against salmonella?

    • Protect human health
    • Prevent feather loss
    • Increase egg size
    • Accelerate bird growth

  11. Which substances do salmonella bacteria secrete that cause symptoms?

    • Toxins
    • Enzymes only
    • Plasmids
    • Chlorophyll

  12. Which precaution most directly reduces gonorrhoea spread?

    • Sleeping outdoors
    • Using a condom
    • Sharing needles
    • Drinking tap water

  13. Term for a bacterial population that survives treatment with a specific antibiotic?

    • Resistant strain
    • Dormant culture
    • Symbiotic colony
    • Mutated virus

  14. Why does unhygienic food preparation increase the risk of salmonella?

    • Allows bacterial contamination
    • Destroys natural toxins
    • Increases cooking temperature
    • Spreads fungal spores

  15. Which symptom distinguishes salmonella from gonorrhoea?

    • Skin blistering
    • Muscle stiffness
    • Abdominal cramps
    • Hair loss

  16. Which medical intervention is used to cure an active gonorrhoea infection?

    • Antibiotics
    • Fungicides
    • Vaccinations
    • Antivirals

  17. How can the transmission of gonorrhoea be controlled?

    • Sterilising water
    • Antiviral drugs
    • Barrier methods
    • Vaccination programmes

  18. What do bacteria secrete that causes symptoms of disease?

    • Antibodies
    • Plasmids
    • Toxins
    • Antigens

  19. Why are antibiotic-resistant bacterial strains a major concern?

    • They reproduce slower
    • They survive treatment
    • They lose toxins
    • They cannot spread

  20. Which pairing of pathogen and disease is correct?

    • Protist: gonorrhoea
    • Bacteria: gonorrhoea
    • Virus: gonorrhoea
    • Fungus: salmonella
