What is the Unit About?
Unit Description
 

Introduces students to diagnostic medical bacteriology. Skills taught include: processing of clinical specimens, recognition of normal microbiota, identification of pathogens and the undertaking of appropriate antimicrobial susceptibility tests. Students learn: aspects of laboratory safety, epidemiology, pathogenesis and control of infectious diseases; antimicrobial agents and development of resistance; infection control; rapid and automated diagnostic technology; quality control; media preparation and waste management.
Intended Learning Outcomes
As per the Assessment and Results Policy 1.3, your results will reflect your achievement against specified learning outcomes.
On completion of this unit, you will be able to:
1.
Describe the common infectious diseases of major organ systems and the associated bacterial pathogens
2.
Describe and discuss the systematic laboratory investigation of common bacterial diseases, and interpret, analyse and evaluate the relevance of laboratory findings to clinical presentation.
3.
Identify common bacterial agents in a mock clinical setting and interpret, analyse and evaluate the relevance of laboratory findings to clinical presentation.
4.
Interpret and evaluate contemporary scientific literature related to bacterial infections and discuss the impact on the routine practice of diagnostic microbiology.

Alterations as a result of student feedback
The order of modules has been changed so that antibiotics and susceptibility testing occurs early in the semester and practised throughout the remaining content. An additional regular 1 hr weekly workshop has been added to provide additional face to face contact.

Attendance / engagement expectations
If your unit is offered On campus, it is expected that you will attend all on-campus and onsite learning activities. This is to support your own learning and the development of a learning community within the unit. If you are unable to attend regularly, please discuss the situation with your course coordinator and/or our UConnect support team.

If your unit is offered Online, it is expected you will engage in all those activities as indicated in the Unit Outline, including any self-directed learning.

If you miss a learning activity for a legitimate reason (e.g., illness, carer responsibilities) teaching staff will attempt to provide alternative activities (e.g., make up readings) where it is possible.

How your final result is determined
To pass this unit, you need to demonstrate your attainment of each of the Intended Learning Outcomes, achieve a final unit grade of 50% or greater, and pass any hurdle tasks.
 
Submission of assignments
Where practicable, assignments should be submitted to an assignment submission folder in MYLO. You must submit assignments by the due date or receive a penalty (unless an extension of time has been approved by the Unit Coordinator). Students submitting any assignment in hard copy, or because of a practicum finalisation, must attach a student cover sheet and signed declaration for the submission to be accepted for marking.
 
Requests for extensions
If you are unable to submit an assessment task by the due date, you should apply for an extension.
 
A request for an extension should first be discussed with your Unit Coordinator or teaching support team where possible. A request for an extension must be submitted by the assessment due date, except where you can provide evidence it was not possible to do so. Typically, an application for an extension will be supported by documentary evidence: however, where it is not possible for you to provide evidence please contact your Unit Coordinator.
 
The Unit Coordinator must notify you of the outcome of an extension request within 3 working days of receiving the request.
Late penalties
Assignments submitted after the deadline will receive a late penalty of 5% of the original available mark for each calendar day (or part day) that the assignment is late. Late submissions will not be accepted more than 10 calendar days after the due date, or after assignments have been returned to other students on a scheduled date, whichever occurs first. Further information on Late Penalties can be found on the Assessments and Results Procedure.
 
Review of results and appeals
You are entitled to ask for a review of the marking and grading of your assessment task if there is an irregularity in the marking standards or an error in the process for determining the outcome of an assessment. Details on how to request a review of a mark for an assignment are outlined in the Review and Appeal of Academic Decisions Procedure.
