Unit of study_

AVBS2001: Introductory Veterinary Pathogenesis

The overarching theme for this unit of study is the concept of the interaction between the host (or the animal), the agent of disease (genetics, physical, chemical and infectious agents) and environmental factors. In disease states, the host responds to the aetiological agent of disease and the environment through one of the basic five pathological processes that occur in tissues. These include inflammation and repair, degeneration and necrosis, circulatory disturbances, tissue deposits and pigments, and disorders of growth. A case based approach will be used whenever possible to illustrate these principles and enable the student to develop a problem solving approach and the skills of critical thinking.

Credit points 6
Assumed knowledge:
The basic structure, morphology, metabolism and behaviour of bacteria, viruses, and fungi. Fundamental histological structure and function of cells and key tissues, including blood vessels, skin, liver, lung, kidneys, intestine, and organs and cells of the immune system (lymph node, spleen, white blood cells)

At the completion of this unit, you should be able to:

  • LO1. describe the pathogenesis of disease in terms of the basic interactions between the host, agents of disease and the environment
  • LO2. apply an understanding of the host-pathogen-environment interaction to propose potential ways that environmental changes (natural or in husbandry) might increase or decrease the susceptibility of the host to disease
  • LO3. explain the concept that the basic pathological processes of immunity, inflammation and repair, circulatory disturbances, disorders of growth and tissue deposits and pigments are host responses that manifest as disease. You should be able to describe what each of these processes involves, relate them to the changes that take place in tissues, and, on an elementary level, recognize and methodically describe and interpret these changes in histological sections
  • LO4. describe the range of agents of disease (such as genetics, physical (e.g. heat, trauma) and chemical agents (e.g. nutrients, toxins and drugs) and infectious agents; describe the basic structure, morphology and behaviour of infectious agents of disease (including bacteria, viruses, fungi, protozoa and metazoa), and explain the general mechanisms by which they cause disease
  • LO5. evaluate the usefulness of cytology, histopathology, practical microbiological and parasitological techniques and immunology- based tests in disease investigations in both diagnostic work and research and be able to select appropriate specimens for these techniques
