What is serology?
Combine known antiserum plus unknown bacteria
using antibodies
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 does Plemorphic mean?
Many Shapes
What is mycology
The study of fungi

3.5 billion Years Old
How old is the oldest Eukaryotic fossil?
1.4 billion years
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 is the definition of a bacterial species?
All pathanogenic prokaryotes and non-pathonogenic prokaryotes found in soil and water.

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
How is Salmonella taxonomically divided?
