Microbiology Chapter 3 Bio-Rad

A unicellular organism that lacks a nucleus and membrane bound organelles

A cell that contains a nucleus and membrane bound organelles

purple

pink

Discovered penicillin in 1928

The test to determine the efficacy of antibiotics or the antibiotic resistance of bacteria. Zone of Inhibition

antibiotic

a shallow dish used to culture bacteria

preventing infection; having a cleansing effect

a bacterium, virus, or other microorganism that can cause disease.

the disease that killed a large part of the European population in the Medieval times

ancient bacteria; live in extreme conditions

A kingdom that contains all prokaryotes except archaebacteria

rod shaped

spiral shaped bacteria

sphere shaped bacteria

a metal rod with a small wire loop at the end, used as a swab

glass or plastic tube that holds samples within a centrifuge

Tubes ideal for cell centrifugation.

used to heat substances

An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.

colony forming unit

the purpose of this procedure was to obtain isolated colonies

the process of diluting a sample several times

A numerical representation of the film's ability to transmit light. Measure how cloudy a concentration is. Determine cell concentration.

Amount of light sent through the sample

The amount of light absorbed by a sample

series of guidelines used to identify the microorganism that causes a specific disease

The suspected pathogen must be grown in pure culture

The same pathogen must be present in every case of the disease

The same disease must result when the isolated microorganism is inoculated into a healthy host

The organism should be reisolated and shown to be the same as the original

Gelatin-type material derived from seaweed

a nutritionally rich medium, is primarily used for the growth of bacteria

Developed a vaccine for rabies & anthrax.

an organism that is microscopic in size, may exist as single cells or colony of cells (aka microbe)

determine if microorganisms cause disease

the compounds that build cell walls in gram positive and negative cell walls.

without oxygen

occurring only in the presence of oxygen.

the study of microbes

Enclosed, ventilated lab workspace

Type of bacteria found at Yellowstone National Park

A medicine created using genetically modified bacteria.

Bacteria sexual reproduction

true bacteria

considered ancient life forms that evolved separately from bacteria and blue-green algae

Makes proteins

small, circular piece of DNA located in the cytoplasm of many bacteria

short, hairlike protein structures on the surface of some bacteria

A long, whip-like filament that helps in cell motility. Many bacteria are flagellated, and sperm are flagellated.
