Addendum to Course Description
This course reviews and further develops the knowledge and skills of the basic practices and principles of bacteriology learned in MLT 113: Introduction to Medical Microbiology. The focus is on the general practices employed for identifying the clinically important bacteria encountered in the blood, central nervous system, and genitourinary tract, and the correlation of normal and abnormal findings as related to specific infections.
Intended Outcomes for the course
Upon completion of the course students should be able to:
- Make decisions about specimen acceptability and workup using an understanding of the normal flora and common pathogenic organisms associated with human infections of the circulatory, central nervous, and genitourinary systems.
- Apply appropriate microbiology techniques, methodologies, instruments and equipment to affect quality patient care.
- Adapt bacteriology laboratory techniques and procedures when errors and discrepancies in results are obtained to effect resolution in a professional and timely manner.
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.
