• Bacteria
• Viruses
• Parasites

Bacteriology

Virology

Parasitology

Mycology

disease producing

the "cell"

cell theory

bacteria called them animacules

Spontaneous Generation

(living things are derived from inanimate objects)

Swan-Necked flasks or " U " tubes

No contamination of media

• water
• sugar
• proteins
• fats

it is a material that organisms can utilize to grow on and in

Proof of Biogenesis

all living cells arise only from pre-existing cells

Pasteurization and Fermentation

" Vaccine "

as he worked with the virus that causes rabies

Father of Immunology

how we fight infection

preparation of a weakened microorganisms that produce immunity

cowpox were immune to smallpox

aseptic surgery

a mold- Penicillium notatum produces a waste product that prevents bacteria from growing called it

penicillin

antibodies in immunity

Ehrlich worked with the disease syphilis

" chemotheraphy "

which means treating a disease by chemical substances

solid culture agar media

are organisms growing on and in media

is when only one organism is growing on the media

is when two or more organisms are growing together

is a complex sugar used as a solidifying agent in culture media

Koch set forth certain criteria for establishing that a certain organism causes a specific disease

;

;

The most important step is to inoculate a pure culture of the organism into a healthy animal

;

;

;

that causes T.B.

it is called Mycobacterium tuberculosis

;

;

Germ theory

which states a specific microorganism causes a specific disease

;

;

;

;

the classification and naming organisms

5 Kingdoms

;

1. Monera;;; contains bacteria ; blue-green algae

2. Protista;;;conains slime molds ; other algae

3. Fungi;;;;;; contains yeast ; molds

4. Plant

5. Animal

Genus;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Specie

;

Ex. Mycobacterium;;;;;;;;;;;;;;;;;;; tuberculosis

;

Ex. Staphylococcus;;;;;;;;;;;;;;;;;; aureus

;

Ex. Staphlococcus;;;;;;;;;;;;;;;;;;;; epidermis

Ex. Streptococcus

Ex. Human cells - Animal - Fungi

have DNA in nucleus surrounded by nuclear membrane

have organelles

Particularly a mitochondria

cell respiration occurs at the mitochondria,;

;;; this is where cell makes;energy

Energy is in the form of a compound called ATP

;

;

are bacteria cells -cell wall semi-rigid

;

have DNA, but no membrane compound

No nuclear membrane

No organelles

No mitochondria

No large ribosomes

some bacteria are motile-have flagella (do not have cilia)

;

;

;

procaryotic

simple cells

;

;

;

cell walls

;

;

;

binary fission

;

;

;

cell membrane

ATP

;

;

;

movement

by flagella

;

• Round
• Rod
• Spirals

;

;

;

Eucaryotic

;

;

-They require organic material for growth

; sugar-proteins-lipids=fat

-They do not use sunlight or CO_²

-They are NOTclassified as a plant

;

;

;

;

unicellular (yeast)

multicellular (molds)

;

;

;

cell walls

;

;

;

sexually or asexually

;

;

are parasites

They are Eucaryotic

;

;

;

;

unicellular and have a complex structure

Ex. flagella, cilia

;

;

;

locomotion

;

;

;

cell walls

;

;

;

sexually or asexually

;

;

;

cells

Molds - texture and flavor of cheeses

;

Insect Control - the microorganism is specific for the insect

;

;

;

DNA or RNA

;

;

;

protein coat

;

;

-They do not metabolize nutrients to carry out chemical

; reactions

-They cannot reproduce themselves

;

;

;

living cell to reproduce
