Tools for lab Flashcards
Culture
To grow a microbe
Sample or group of microbes
Medium
nutrients for the growth of microbes
Inoculum
a small sample of microbes
Inoculation
a sample microbe is placed in media with a tool
Clinical Specimens
from the bodily fluids, discharges, anatomical sites, diseased tissue
Incubated
placed in a temperature-controlled area
Cultured Media uses
Flask, Petri dishes, and tubes
Media inoculated with
Needle, loops, swabs, pipes
Media Classified by
Physical state, chemical composition, and function(purpose)
Agar
complex polysaccharide from red algae; Solid at room temp Melts at 100 C holds moisture and nutrients Microorganisms cannot digest
Physical states of media
Liquid(Nutrient broth)
Solid that can be liquid( media has levels of agar)
Solid that cannot be converted to liquid
Semi-solid (media has low levels of agar)
Chemical Composition of Media:
Defined/ Synthetic
We know all the components of media chemical
Chemical Composition of Media:
Complex
One component of media is not precisely defined
Media Purpose/Function:
General-purpose media
Allow the growth of a broad spectrum of microbes
Media Purpose :
Enriched media
grow microbes that need special growth factors
