Explanation / Answer

1. How many compartments does the Enterotube II have?

d) 12

Enterotube II is a multi test system used to identify bacteria in the Enterobacteriaceae family. The tube consists of 12 compartments for different biochemical tests.

2. Lab exercise 8-5: If the patient's RBCs agglutinate in the presence of anti-A antiserum, this indicates:

In blood typing, RBC from patient is mixed with antibodies raised from monoclonal population of B-cells. Three different bottles of anti-A, anti-B and anti-D are used.

3. Why is the milk heated to 185 degrees Fahrenheit and cooled before adding yogurt?

            e) Pasteurize milk

This kills any unwanted bacteria that may compete with yoghurt making bacterial culture.

4. Lab exercise 8-6: A conjugate antibody has __________ attached to it:

a) An indicator molecule

A conjugated antibody is a monoclonal or polyclonal antibody which has a label attached to it and is used for detection in different assays. Conjugated antibodies are usually attached to colorimetric or fluorescent labels.

5. The tests of the Enterotube II are primarily based on:

d) Enzymatic activity

Enterotube contains twelve different media that determines different biochemical reactions and thus detects the bacteria.
