lab 2

used to isolate or differentiate enteric organisms based on their ability to ferment the disaccharide lactose. It also inhibits the growth of Gram + bacteria, selecting for growth of enteric.

Used to observe the continuous covering of bacterial growth, antibiotics may be applied to the plate to see how much they affect the growth of certain bacteria. First, you must use a sterile plastic pipette and sterilized microbiological spreader to apply a broth to a TSA medium on a Petri plate

The process that completely destroys all microbial life, including spores.

The process of destroying pathogens

Y shaped molecules that can bind to specific molecules, including those on the surface of pathogens. The binding sites on these antibodies are very specific to the pathogen that it is fighting

number of individuals/unit who have disease at any one time

number of new cases of a disease

selective and differential; Staph- species, but mainly the growth and isolation of S. aureus.

An enzyme produced by certain types of bacteria; It is useful in differentiating between Staph and Strept species

This media is used for the primary isolation of organisms and for subculture of organisms; diagnosis of infections caused by strept species

Used to differentiate Gram negative enteric organisms based on the ability to reduce sulfur and ferment carbohydrates

They ferment lactose

Gram-negative bacteria that inhabit animal intestinal tracts

for running 12 tests concurrently, high probability of rapid identification
