Course DescriptionIntroduces clinical bacteriology and the taxonomic approach to major human pathogens. Presents an overview of the organization and function of the clinical microbiology laboratory. Introduces basic practices of specimen processing, handling, and work-up. Develops basic skills necessary to work in the microbiology laboratory. Prerequisites: Acceptance into the Medical Laboratory Technology Program. Audit available.
Addendum to Course Description
This course provides an introduction to clinical microbiology. Focuses on the development of knowledge and skills required to practice medical microbiology. Addresses the transmission and control of pathogens, epidemiology, determination of the significance of isolates, and safety issues in the clinical microbiology laboratory. Students will be expected to properly perform laboratory exercises related to the subject matter discussed.
Intended Outcomes for the course
- Use an understanding of the normal and common pathogenic organisms associated with human infectious diseases to make appropriate and effective on-the-job professional decisions.
- Apply appropriate microbiology laboratory techniques, methodologies, instruments and equipment in accordance with current laboratory safety protocol.
- Calculate, record, and report clinical microbiology results according to clinical laboratory protocol.
Course Activities and Design
The class is presented by means of lecture/discussion, audio-visual presentations, handouts, demonstrations, web based instructional media and other educationally sound practices. Comprehensive lab work requires demonstration of competency to receive a satisfactory grade. A laboratory manual is provided. The laboratory exercises provide an opportunity for students to employ the testing principles and methodologies discussed and allow for discussion, application and correlation of the concepts presented. The student is expected to perform all laboratory procedures according to the criteria established by the department.
Outcome Assessment Strategies
Assessment methods may include written and practical examinations, homework assignments and discussion activities. Student knowledge application, laboratory performance, problem solving skills, punctuality and attendance, participation, and communication skills is assessed in each laboratory exercise utilizing an evaluation rubric that includes cognitive, psychomotor and affective learning domains.
