Description Infectious diseases worldwide are the most common cause of illness. Medical microbiology is subdivided into four areas: virology, bacteriology, mycology (the study of fungi) and parasitology. The rapid evolution of microbes means that this is an area that does not remain static. This subject has a modern approach to the study of the balance between the host, humans, and the very large army of potential invaders. Students will embark on a journey into the world of pathogenic micro-organisms exploring the molecular mechanisms by which these override host defences leading to disease. Infectious diseases of the human body systems as well those of the immunocompromised and infections contracted in the healthcare setting (nosocomial) are discussed. The theory will be supported with laboratory experience representing diagnostic procedures for the identification of infectious agents.

Learning Outcomes

On successful completion of this subject, students should be able to:

  1. Differentiate the mechanisms of infections caused by true pathogens from those caused by opportunistic pathogens
  2. Describe the factors and mechanisms by which the human host is protected from microbial invasion
  3. Understand and apply appropriate biochemical and molecular techniques used in the identification of clinical specimens
  4. Explain the rationale behind the performance of antimicrobial susceptibility tests
  5. Analyse and interpret scientific literature and effectively communicate
  6. Associate the various infectious agents that affect special populations with the conditions that predispose these patients to a particular infection

Subject Content

1. Principles and practices of medical microbiology
2. Non-specific and specific (immune system) defence of the human body
3. Principles of the pathogenesis of disease including mechanisms by which microbial agents override the host non-specific and specific defence system to produce disease at the molecular level
4. Diseases of the human body systems and respective aetiological agents
5. Specimen collection techniques for the detection of microbial pathogens
6. Laboratory diagnostic procedures for the isolation, identification and antibiotic sensitivities where applicable of microbial pathogens
7. Molecular techniques and development of new diagnostic capabilities for microbial pathogens
8. Current areas of research interests in medical microbiology
