MICR 223: Infection and Immunity

Second Semester - 18 points

Course prescription

The epidemiology and pathogenesis of infectious diseases, the response of the immune system to microbial antigens, and how the response is measured.

Course overview

  • Microbes and the immune response exist in a delicate balance. The immune response is essential for fighting infection by microbial pathogens; however, these pathogens evolve rapidly to develop immune evasion mechanisms.  This paper includes specific discussion on current global disease threats such as HIV, influenza, MRSA, tuberculosis and E. coli 0157:H7.
  • This course in Infection and Immunity aims to integrate microbiology and immunology to:

214A7091

    

 

  •  Explain the mechanisms microbes have evolved to infect cells, individuals and communities.
  •  Provide a broad understanding of fundamental immunology, including innate and adaptive immune systems at a cellular and molecular level
  •  Provide basic practical experience with the instrumentation and methodology important in a modern diagnostic laboratory and how these skills can be applied to human health and disease.

  • This paper is ideal if you are interested in Immunology or Medical Microbiology, and want to understand the interplay between infection and protection.

  • Lab 6: Tuberculosis diagnosis

Attendance at all 6 laboratory sessions is compulsory

Techniques and skills you will learn in the lab course:

  • Culture of bacteria
  • Haemadsorption
  • Immunochromatography
  • Yeast identification
  • Phagocyte function
  • Biofilms
  • Coagulation and agglutination
