Objectives and Scope:         This is an introductory course in Medical Microbiology for undergraduate nursing students with a background in genetics, cell biology and organic chemistry. The overall objectives are to acquaint students with fundamental principles of medical microbiology and common microbiology laboratory techniques with an emphasis on bacteriology. Lectures will identify unifying microbiology concepts with an emphasis on bacteriology, virology and immunology. Laboratory exercises will emphasize procedures involved in isolating, cloning and characterizing bacteria. Some simple applications of mycology, virology and immunology will also be included in the laboratory.


Exams, Reports and Scoring:            A total of 100 points are possible for the course. This is a 4 credit hour course including laboratory. Thus, 60% of the grade comes from lecture and 40% from laboratory. The scoring opportunities are as follows:



First lecture Exam
14 points
Second Lecture Exam
14 points
Third Lecture Exam 
14 points
40 points
Final [Comprehensive] Exam 
18 points



The final comprehensive exam will be constructed as follows: 4 points from material covered for previous lecture exams and 14 points from lectures since third exam. The final laboratory exam will include only material covered in laboratory after the laboratory mid-term exam.





Course Grades:   The total numerical grade is obtained by summing all scoring opportunities. Final letter grade will be translated as follows:         >90% = A,  >85-90% = BA,  >79-85% = B,  >73-79% =  CB, 

>67-73% = C, >61-67% = DC, >55-61% = D and <55% = E. The abuse of laboratory equipment and materials will have a negative influence on the final letter grade assigned. 


Note: This course is, for many students, similar in difficulty to organic chemistry. Thus, do not panic at one or two low lecture grades. The average class laboratory exam grades are, for most students, always higher than average class lecture exam grades.


Make-up Exams: Any make-up exam will be by special arrangement only and will require written documentation for an excused absence. Exams are to be made-up immediately after return to class and only approved excused absences are eligible for an essay make-up exam.


Disputed Grades: Any dispute in the final letter grade must be resolved within first week after the final grades are assigned.


Academic Honesty:  Academic ethical standards regarding cheating, fabrication, plagiarism, facilitating academic dishonesty and consequences of these actions are all described in the WMU Undergraduate Catalog. It is IMPORTANT to familiarize yourself with the written definitions described in the catalog. Reading these university regulations is strongly recommended. Any student who violates these standards of academic honesty will receive a failing grade in this course.


Students are required to provide their student identification card on request by a faculty member or a teaching assistant. Thus, all students must have their student ID available when exams, reports or other reasons may require a faculty member or teaching assistant to ask for a student’s official ID card.
