Microbiology

made advancements in the 19th century in microbiology

was the first to observe microscopic life (blood, plaque, algae)

know as T.B.

know as Bacteriology

know as phcology

know as protosology

know as virology

• -prokatyotic
• -no nucleus
• -cell type is simple

0.5-5.0 microns

herterotrophic

human (organic molecules)

• -some cause diseases (ecoli, saminalia, strep, tetnius)
• -very few cause diseases

nitrogen fixing bacteria

• this is when living organisms metabloize
• ex. (dead animal on the road decomposing gives back carbon dioxide in the air and nutirents to the animals and plants.

corn, the other carbohydrate

• -eukaryotic
• -single cell (unicellular)
• -multicellular (colonies)

100 microns

it can with stand very cold and very hot tempeatures

• -photosynthetic
• -primary producer of organic molecules

O2

Ex. the "red tide"...harmful alage that bloomed in the Gulf of Mexico and made the water appear red from the microorganisms.

(unicellular) yeast and (multicellular) molds,mildows and molds)

a few to 100 microns

only orgnic matter

decomposing of any naturally occuring organic molecules.

non living organisms can breakdown this stuff

prokaryoric

unicellular and colonies (protozon, alage)

cell wall photosynthetic and atrophic

cell wall, made of (chitin)

lacks a cell wall, hetero, eukaryotic, mulitcellular (only in amimals)

live in harsh enviorments

man and animal

chordata

mammal's

primate

Hominidae

homo (noun)

sapians (verb)

Prokaryotic vs. Eukaryotic

• -bacteria
• -not complex, no nucleus, and no mitocchondria

• (plants, animals, fungi, and protozoans)
• (cellulose and chitin)

-very thin

-bi-layer of phospholipids and protein molecules

-very flexible, selectively permeable

• very thick and riged, the riged body determins the cells shape
• -the cell wall provides protection
• (from loss or gain of water)

1,000 millimeters

1,000 microns

1,000,000 microns

1/1,000,000 of a micron

produce useful products

• -eukaryotic
• -unicellular (some colinies)
• -herterotrophic

live in water, soil, and on the bodies of other life forms.

commersalism

mutalism

parasitism

100mm

they cause decomposition and pathogyn's

• -two species
• -one benifts form the other and on one is affected

both species benefit, one doesnt effect the other.

human and mosquitoes

• not all are cellular (parasite)
• - no independent immune system
• -they are obligated, intrcellular parasites of hosts cells

they are 1/1,000 of a micron and are harmful

all living organisms

it kills the host of the cell

few bateria are without a cell wall, in bateria the shape will be off.

are bacteria that naturally lack a cell wall

naturally arise form mutaiton in the wall forming genes.

-they also can be induced artifically by treatments.

breaks down cell wall material of certain bacteria

-some bacteria have posionous cell wall material

• -is a capsule or silver layer
• -slimy secretion of cell membrane
• -located ext. to the cell wall

• it varies on the enviormental conditions
• (98%, H2O and 2% polysacch or polypeptide)

Pneumovax

75 different strains

milk kills bacteria and pathogens which the bacteria causes the milk to become "ropy"

• the glue of life
• ex. (build up on the toliet bowl, or shower, algae on the sides of the swiming pool and plaque on your teeth)

eukaryotic cell "true nucleus" 3-700x more that bacteria.

circular

mass of DNA molecules/"naked DNA"

mitosis, DNA

• 1. conjunction
• 2. tranformation
• 3.transduction

needs (pili) to attatch species and the formation of a bridge to transport DNA

eats the host, (hazard) not as controlled

virus

"recombinant bacteria": (recombination of genetic material)

• -antibiotic resistant strains of bacteria
• -species which produce useful products/service.

function is proteinsynthys, site of protein molecules

ribosomes, prok, euk.

they are visable with a light microscope & organic matter..."food"

source of Nitrogen

make things float

causes anthrax

botulism (food posining)
