Describe the TWO main characteristics of Lysogenic (temperate)
bacteriophage replication -ANSWERS-It doesn't replicate and does not
kill the host cell
It integrates itself into the host genome and multiplies with the host
cell as the host cell multiples.
Bacteria that have a CURVED rod morphology are referred to as -
ANSWERS-Vibrio

You want to observe the movement of microorganisms that are present
in a sample of cheek cells obtained on a patient . Briefly explain the

the motility of the organism is the priority observation we would need
to use a wet mount. A liquid culture with the microorganism is added to
a slide with a coverslip to hold the microbes in place.
Explain the difference between a simple stain and a wet mount stain
technique. When would each be indicated for use? -ANSWERS-A wet
mount is normally used for live samples, especially when observing
, motility. A liquid broth with the microbes are added onto a slide with a
coverslip for protection and is observed under a microscope.

1. A multi - purpose media capable of growing a wide variety of
microorganisms
2. Also known as lysogeny broth , it is a multi - purpose media capable
of growing a wide variety of microorganisms .
3. Pale red in color and is both selective and differential media . The
presence of crystal violet and bile salts in its formulation restricts Gram
positive bacterial growth . As such , only Gram negative microbes can
be grown .
