  • Communicable Disease
    • Pathogens
      • bacteria damages cells by releasing waste and toxins, it replicated by binary fission e.g. TB or Ring rot
      • viruses damage by invading cells and taking over genetic machinery to make their own copies e.g. HIV or Influenza
      • fungi infects by growing under the surface and replicated by specialised reproduction e.g. Athletes foot or ringworm
      • protoctists infect by entering the host cell and feed on the content e.g. malaria
