Making a Dichotomous Key with several<\/span>
Biochemical Results to solve for Gram Negative \u2018Unknown\u2019 Bacteria<\/span>
Introduction<\/span>
This exercise is designed to mimic what occurs to identify an unknown bacterium that is infecting a<\/span>
patient. Clinical microbiologists receive patient samples every day in the lab. They are tasked to<\/span>
identify the pathogen infecting patients. Thus, care must be used to properly identify the organism,<\/span>
while maintaining strict BSL2, and at times BSL3, guidelines.<\/span>
Upon receiving a patient\u2019s sample, the patient\u2019s information is logged into a computer. The<\/span>
microbiologist then cultures the sample on various types of media that will support its isolation and<\/span>
growth. For this, both rich and selective media are used. The microbiologist looks for individual bacterial<\/span>
colonies present in the sample. Next, a Gram stain is performed to determine if the bacterium in<\/span>
question is a <\/span>1. Generate a Dichotomous Key using the information provided in Table 11.1:<\/span> <\/span>Biochemical<\/span>
Characteristics Of Gram Negative Bacteria<\/span>.<\/span> <\/span>Later, you will use this information to<\/span>
identify your unknown bacteria.<\/span>
A dichotomous key is a tool that allows the user to determine the identity of items in the<\/span>
natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish, etc. These<\/span>
Keys consist of a series of choices that lead the user to the correct name of a given item.<\/span>
“Dichotomous” means “divided into two parts”.<\/span>
2. Referring to the biochemical properties of bacteria given in Table 11.1, create a Dichotomous<\/span>
Key.<\/span>
3. Biochemical test reactions are recorded as a \u2018yes\u2019 or \u2018no\u2019 (+ or -) result.<\/span>
4. Once you complete your Dichotomous Key, you will have several branches of bacterial species<\/span>
each ending at a unique species (name of the organism).<\/span><\/p>\n

5. You will then use this Dichotomous Key to solve for your \u2018unknown\u2019 bacteria (identify its Genus<\/span>
and species name) based on the test done on your assigned organism using API 20e strips. You<\/span>
will then complete the lab report of this exercise and submit it in Canvas for a grade.<\/span>
