Questions and Answers

In order to survive, pathogens require a source of nutrients, protection from harmful elements and:

  • Dissemination through the oesophagus
  • Colonization of a niche in the host (correct)
  • Access to the vascular system
  • Access to the digestive system
  • Some enveloped viruses use antigenic variation which makes it difficult for the immune system to recognise different strains of the virus. Which type of antigenic variation results in a major change in spike proteins due to gene reassortment?

  • Antigenic shift (correct)
  • Antigenic drift
  • Antigenic draft
  • Antigenic shaft
  • Which pathogen type is always a member of the normal microbiota and only causes disease in an immunocompromised host?

  • Primary pathogen
  • Individual pathogen
  • Discreet pathogen
  • Opportunistic pathogen (correct)
  • Which type of pathogen is an environmental microbe that is able to cause disease in an otherwise healthy individual?
