|
What does Pleomorphic mean?
|
Many shapes
|
|
|
What is slide Aggultination? What is it used for?
|
When Anti-serum is added to the sample bacteria. The Bacteria clump when mixed with anti-bodies that were produced in response to that species or strain of bacteria. It is used to identify bacteria
|
|
|
What is the G to C ratio?
|
It is a test that shows DNA base composition. It can reveal the degree of species relatedness

|
What is Nucleic acid hybridization?
|
When DNA strands are seperated and combined with unknown strands to determine the degree of hybridization. Partial organisms are related. Identical is an exact match. No hybridization, unrelated.
|

|
What are the stages of Chlamydia in order?
|
1) bacterium elementary body attaches to host cell
2)host cell phagocytizes the elementary body, housing in a vacoule. 3) Elementary body reoganizes to form a reticulate body. 4) The reticulate body divides successively to produce multiple reticulate bodies. 5)The reticulate bodies convert back to elementary bodies 6)The elementary bodies are release from the host cell. |
|
|
What does the hiearchy of taxa show?
|
Evolutionary and phylogenic relationships
|
|
|
What is phage typing?
|
Use specific phage typing species to identify a bacterial culprit and follow it's disease throughout it's course.
Bacteria is spread on an agar plate and the clear area is where a very particular phage virus has lyced specific cells |
|
|
What are plaques?
|
Clear area of bacteria death
|
|
