Diagnostic Bacteriology

Antibody cross-links whole-cell antigens, forming complexes that settle out and form visible clumps

• Western blot

• Agglutination testing

• Complement Fixation

• Precipitation Test

Test that can be used to identify the amount of antibody in a serum

Inhibit growth of some microbes and encourage growth of the desired microorganisms.

• General purpose media

• Enriched media

• Differential media

• Selective media

Type of staining where the microbe repels the dye, which stains the surroundings

• Negative staining

• Positive staining

• Differential stain

• Simple staining

Indirection association of likely pathogens by looking at antibodies in the serum and antigens of the agent

• Blood

• Culture

• Clinical Specimen

• Serology

Detection of presence or absence of particular enzymes or metabolic pathways

• Chemical analysis

• Pus with foul odor

• Tend to involve few organisms

• Abscesses or tissue burrowing

Transforms subtle changes in light waves passing through the specimen into differences in light intensity; for observing intracellular structures

• Fluorescence microscope

• Bright-field light microscope

• Phase-contrast light microscope

• Electron microscope
