Definitions
The microbes that live on or in a normal healthy human body
Normal Flora
first microscope invented,magnifies up to 2000x, were blurry when magnified and light issues
compound/light microscope
Organisms that live in especially harsh conditions, high temp, acidic, salty
Extremophiles
Conversion of atmospheric nitrogen into a nitrogen containing molecule that organisms can use
Nitrogen fixation
Reproduction of viruses using hosts bio machinery, resulting in lysis to host cell to release visions. Host cell dies
Lytic cycle
a liquid culture that contains the nutrients the microbes needs
broth culture
gram positive stains are what color
purple
organisms that must have oxygen in order to survive
Obligate aerobes
Bacteria that capture energy from light
Photosynthetic
an individual virus is called
virion
A subtype of organism within the species grouping, sometimes called a serotype
Strain
the strongest microscope which can magnify up to 500 million x
STM Scanning tunneling microscope
What is the one extremophiles that is not named for where it lives
Methanogens
A tough structure that protects a dormant bacterium and allows it to become freely living once external conditions become suitable for life
Endospore
Viral nucleic acids inserted into host genome and replicates as the host cells replicate, may be called temperate infection
Lysogenic cycle
The study of blood serum & immune responses
Serology
red stain is called what
gram negative
Unlike bacteria Archaea do not have what in their cell wall
peptidoglycan
Which gram - bacteria are responsible for nitrogen fixation
alphaproteobacteria
when a viral DNA does not seem harmful but the right environmental conditions cause the viral DNA to leave the host genome and enter lytic cycle
latent infection
Organisms that can perform aerobic respiration but can switch to fermentation when little or no oxygen is present
Facultative anaerobes
Gram positive bacteria are what 2 groups
firmicutes & sctinobacteria
Halophiles, acidophiles, & thermophiles each have a different special kind of what that allows them to survive their extreme environments
proteins
What 3 shapes can bacteria be
coccus-spheres
bacillus-rods
spirillum-spiral
what 2 macromolecules are found in viruses
protein & nucleic acids
