AVBS2001: Introductory Veterinary Pathogenesis

Semester 2, 2025 [Normal day] - Camperdown/Darlington, Sydney

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.

Early feedback task

This unit includes an early feedback task, designed to give you feedback prior to the census date for this unit. Details are provided in the Canvas site and your result will be recorded in your Marks page. It is important that you actively engage with this task so that the University can support you to be successful in this unit.

Assessment summary

  • Mid-semester exam: This will be an onsite, pen and paper exam comprising MCQ and short answer questions covering the four pathological processes- cell injury, circulatory disturbances, disorders of growth and immunology/inflammation. This assessment is compulsory and failure to attend, atttempt, or submit will result in the award of an AF grade.  If  a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam).  The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.
  • Learning portfolio: – see Canvas
  • Final exam- theory: This will be in the final exam period and will cover all aspects of the unit. As it has already been partially examined by MCQ in mid semester, the component on pathological processes will particularly focus on higher order topics, such as interactions between pathological processes in disease. The final exam assessment is compulsory and failure to attend, atttempt, or submit will result in the award of an AF grade.  If  a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam).  The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.
  • Histopathology assignment: This will involve description and interpretation of abnormal histological sections in a canvas-based exercise. Detailed information will be provided on Canvas and during semester

Detailed information for each assessment can be found on Canvas. 

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2021 (Schedule 1).

As a general guide, a High distinction indicates work of an exceptional standard, a Distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

85 - 100

This work shows excellent understanding of the topic and clear evidence of independent
critical thought. It may contain blemishes, but these are compensated for by signs of high
intellectual quality, especially clear, well-organised and forceful argument; reading and
understanding beyond the set literature; and originality of approach.

Distinction

75 - 84

This work shows a very good understanding of the relevant content; the essay reflects
independent thought; significantly it attempts to develop evaluative and critical arguments.
Such arguments may be second-hand and/or they may be flawed, but a serious and
sustained attempt at criticism has been made.

Credit

65 - 74

This work shows a clear understanding of the relevant material; it contains only small gaps
or minor errors; reading has obviously gone beyond lecture material; there are signs of
independent thought, and some attempt is made to evaluate arguments or develop critical
arguments.

Pass

50 - 64

This work shows evidence of a satisfactory level of understanding of the relevant material; it
may contain gaps, errors or other kinds of blemishes, but it is obvious that the student has
read and digested material from lectures and/or set literature. The essay, however, is largely
derivative – it simply reports the views of others - and little or no criticism or evaluation of
arguments is attempted.

Fail

0 - 49

When you don’t meet the learning outcomes of the unit to a satisfactory standard. There may be a significant amount of ‘parroting’ of material from lectures or tutorials or set
reading, but this work shows little or no evidence of satisfactory understanding of the
relevant content; it may contain either serious errors or major gaps in what is considered
essential information.

Attendance and class requirements

This unit consists of online preparatory lectures and quizzes, and face to face whole class tutorials and practical classes. All live sessions will be recorded and made available under "Recorded lectures" in the navigation bar for future revision. 

Face to face attendance is a 2 hour tutorial or prac class in most weeks. Lecture material is online (there are no face to face lectures) and these, as well as prep quizzes, should be completed before the associated tutorial or prac session. Attendance for all tutorials and practicals will be monitored by QR code scanning. Please ensure you:

  • Arrive on time to scan the QR code displayed at the venue
  • Use your device (phone or tablet) to scan the code
  • Report any issues to your instructor promptly if you are unable to scan

Students are expected to attend at least 9 of these 11 sessions but you should aim to attend 100% if you wish to be successful in this unit. Failing to meet these attendance requirements may result in you being awarded an absent fail grade in this unit. If you have a legitimate reason for your absence, you must submit a special consideration application so that your absence can be officially note and taking into consideration in the event you fail to meet the above attendance requirement. When submitting an application for absence noting to special consideration you MUST submit a screenshot of this units’ attendance requirement along with other justification documentation to enable your absence to be noted. Note: placements and work shifts are NOT considered valid reason for missing classes.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

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
