Assignments and Methods of Evaluating Student Progress:
1.
Typical Assignments
a.
Lecture. Compare and contrast the cellular components of Gram positive and
Gram negative bacteria. Discuss how these cells respond to antimicrobials in the
context of their cellular structure
b.
Laboratory. Utilizing data gathered from the epidemiology exercise determine the
rate of hand contact transmission of Serratia marcescens in a population. Plot the
data in a chart and determine the prevalence of infection. Given an unknown
culture determine by microscopy and biochemical tests the identity of the
organisms. Proper use of aseptic technique and microscope use is assessed as
well
