Microorganisms & Disease - Course Objectives and Grading Policy

Lecture Objectives [Schedule]

After you have completed this course:

1. You should be more aware of and able to recognize the important ecological, medical, social, and economic roles of microorganisms in the biological world.

2. You should be able to recognize and relate the basic similarities and differences of microbes and eukaryotic life forms from structural and functional standpoints.

3. You should have gained an awareness of and an understanding of the problems and techniques involved in the cultivation, maintenance,and identification of microorganisms.

4. You should have obtained a deeper understanding of the means used by microorganisms to cause disease and of the defensive measures provided by the human body.

5. You should be able to recognize the various types of disease agents and means by which disease organisms are transmitted.

6. You should have gained a familiarity with specific diseases induced by microorganisms.

7. You should be able to critically evaluate the various methods used to control microorganisms, being acutely aware of the role you (humans in general) have in transmitting microbes and creating resistance in many as the result of misuse, overuse and abuse of chemical controls in particular.

8. You should have become more aware of recent advances in all areas of microbiology and related molecular biology through various print and electronic media sources.

BIOL 2275 Microorganisms and Disease


Fall 2006


There will be three (3) examinations given in the lecture portion of the course. The third and final exam will be given during finals week. Each examination represents 1/5 of the final grade. Therefore the lecture portion of the course represents 3/5 of your final grade. These examinations will consist of objective questions (e.g. multiple-choice) taken from sources consistent with the type of career choices most microbiology students pursue.


The laboratory portion of the course represents 2/5 of your final grade and consists of three distinct areas. It is worth a total of 200 points.

1. Quizzes - there will be four (4) quizzes representing a total of 20 points and 20% of the lab grade. These will be unannounced and consist of multiple choice, true-false, and fill-in questions taken from information provided in the laboratory manual or similar materials.

2. There will be two (2) comprehensive lab exams. One at midterm and the other during the last week of classes. Each is worth 80 points. Current thinking suggests that the laboratory exams will have a written and a practical portion.

3. The third component will require the identification of one or two unknown microorganisms using the techniques and skills learned during the semester. Correct identification of each organism is worth 10 points for a total of 20 points.

Grade determinations for lecture and lab examinations and final grades will be based on the following alpha-numeric equivalences:

A = 90 - 100
B = 80 - 89
C = 70 - 79
D = 60 - 69 (60 is the minimum passing grade)
F = BELOW 60

Three Lecture Exams (100 points each) 300 A = 450 points
Lab Exams (200 points)200 B = 400 points
__________ C = 350 points
Total Points (500 points) 500D = 300 points

Students MUST score a total of at least (60%) in the lecture exams and in the laboratory activities in order to pass the course! This means a minimum of 180/300 in lecture and 120/200 in the laboratory. YOU MUST PASS BOTH THE LECTURE AND LAB PORTIONS OF THE COURSE TO PASS THE COURSE.
