gold vaporized by a high voltage electric spark
The three types of bacteria
Bacillus
Coccus
Spirals
The type of bacteria has an outer membrane
Gram negative
Who disproved spontaneous generation?
Units that typical sized bacterium are measured in
micrometers
Type of microscopy that doesn't require a stained specimen.
Phase-contrast
This is a partial spiral
Vibrio
This organelle represents the genetic material in prokaryotes.
Nucleoid
Who created a microscope, observed bacteria, and reported their findings?
Anton Van Leeuwenhoek
This structure allows bacteria to survive high heat
endospore
This technique allows you to look at a thick specimen one layer at a time.
Confocal Scanning Laser
Bacterial arrangement where coccus-shaped bacteria are joined end to end without a sheath
streptococcus
Attaches the outer membrane to the bacterial cell wall.
Braun's Lipoprotein
Proved that Bacillus anthracis was the cause of the disease Anthrax.
Robert Koch
The function of fimbriae
Attachment to cells
Total magnification with resolution for a light microscope is limited to 1200x-1500x by this factor.
wavelength of visible light
Bacterial arrangement where bacilli are lined up side by side
Palisade
The terminal amino acid in the tetrapeptide linkage of Gram positive bacteria
D-alanine
Introduced hand disinfection in the hospital.
Semmelweis
The four steps in Koch's Postulates
1. Observe bacteria when disease is present
2. Grow bacteria in pure culture
3. Infect healthy but susceptible test subject
4. If host gets disease, reisolate same bacterium
Electron microscopes can provide images at a greater magnification with resolution than light microscopes because...
The wavelength of electrons is much shorter than the wavelength of visible light
An octet of 8 cocci
Sarcinae
This part of the bacterial cell prevents osmotic lysis in a dilute environment
Peptidoglycan wall
Created the first vaccine.
Edward Jenner
The "glycan" part of peptidoglycan
N-acetyl muramic acid
