Identify types of biological agents


  • Fungi are small organisms that produce spores.
  • It is the spores that may be inhaled or enter the body through the skin.


  • Bacteria are very small single cell organisms, which invade and infect humans.
  • Destroyed by the employment of antibiotics. However, antibiotic resistant bacteria are developing and are becoming increasingly difficult to treat.


  • They are minute organisms which develop within the cells of the body e.g. the common cold, hepatitis, HIV.
  • Recognised as a major source of illness, although usually of short duration.
  • Viruses are microscopic organisms which multiply in the living cells of their hosts.
  • They do not multiply in food, although food may be the vehicle that introduces the virus into the host.
  • Some ten viral particles are sufficient to cause illness, thus it is highly infective.
