a. All the microbes that were living inside the person’s body die when the person dies.
b. Microbial populations grow and spread to different areas of the body after the person dies.
c. Microbes in the body have fewer resources after the person dies, which increases competition.
2 Which of the following statements about cadavers (dead bodies) is most likely to be true?
a. Microbial communities in and around a cadaver change over time.
b. Samples taken from different cadavers always contain the same microbes.
c. The microbial community found in a cadaver is very similar to the one found in a living body.

Purpose
Solve the identity of an unknown bacterial specimen by creating a dichotomous key and using the staining, culturing and biochemical identification procedures you have learned about during the semester.
Possible Organisms
Alcaligenes faecalis
Enterobacter aerogenes
Enterococcus faecalis
Escherichia coli
Proteus vulgaris
Pseudomonas aeruginosa
Salmonella arizoniae
Staphylococcus aureus
Staphylococcus epidermidis
Staphylococcus saprophyticus
Streptococcusbovis
Streptococcus pyogenes
You must write up your OWN dichotomous key for all the possible unknown organisms listed on above. Writing this key requires you use the same type of reasoning used in the Dichotomous key lab. The first step of the key will be the Gram Stain. Subsequent steps will include biochemical tests only.
