Critically review the ways in which pathogens can cause human disease.
Discuss examples of microorganisms and how they cause human disease. A range of microorganisms from different groups should be included e.g. viruses, bacteria, fungi and protozoa. Your essay should include the pathophysiological mechanisms of disease production e.g. toxins. The role of the immune system should also be discussed including its contribution to pathology and methods of evasion by pathogens.
