Throughout the previous modules you have gained information on the methods used to distinguish different bacteria from one another. This activity serves to reinforce the concepts associated with biochemical tests, help you learn the metabolic strategies associated with individual or groups of bacteria, and strengthen your understanding of basic morphological differences. For this assignment, you are to choose one (1) of the groups, either A) oral/respiratory tract pathogens and commensals, or B) urogenital pathogens and commensals or C) gastrointestinal tract pathogens and commensals, and develop a key based on differential staining and culturing, morphology and the suite of biochemical tests available to identify bacteria.

A) Typical oral/respiratory tract pathogens and commensals –

B) Typical urogenital pathogens and commensals

C) Typical gastrointestinal pathogens and commensals –

The grade for your key comprises 5% of your final grade.
