Hippocrates

Founder of Medicine" During the Golden Age in Greece he was a scientist that believed all diseases came from natural causes. He also had high ideals for physicians & an oath was made that is still used today.

Marcus Terentius Varro (116-27 BC)

-One of the first people to propose that things we cannot see cause disease (microorganisms)-"minute creatures grow in swamps and enter body through the mouth and nose

Antonie van Leeuwenhoek (1632-1723)

Merchant who created the first microscope lens

Golden Age of Microbiology (1857-1914)

Golden Age? When

Microscope, stains and dyes,growth media,petri dish, test tubes, bunsen burnerinoculation loop

Taxonomy

The scientific study of how living things are classified

Carolus Linnaeus (1701-1778).

physician, botanist , zoologist ,developed Taxonomy

Phylogenies

the branching patterns of evolutionary relationships

Monera

one celled organism with no distinct nucleus

Ernst Haeckel (1834-1919)

Coined the term ecology; studies helped explain relationships between different species; stated "ontogeny recapitulates phylogeny

Robert Whittaker (1920-1980)

Further developed the relationship between different species adding in Fungi. Lived into the 1980's

Bacteria, Archaea, Eukarya

phylogenic tree of life

binomial nomenclature

A system for giving each organism a two-word scientific name that consists of the genus name followed by the species name

Bergy's manual of Determinative Bacteriology

provides identification schemes for identifying bacteria and archaea

Atom size

10^-10 mnanometer.1 nanometer

protein

what is 10 nm in size

1 micrometer-101/10-1/100 of a eukaryotic cell

eukaryotic cell are generally what size

10^-6micrometer

what size for a general bacteria

Viruses

Pieces of genetic material surrounded by a protein coat

Acellular

viruses are neither prokaryotic or eukaryotic because they are

coccus (cocci)

berry-shaped bacterium

Baccilus

Rod shaped bacteria

Vibrio

comma shaped

coccobacillus

short round rod

spirrulum

spiral

Spirochetes

spiral-shaped bacteria that have flexible walls and are capable of movement

Archea

Domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan

Protists

single-celled or simple multicellular eukaryotic organisms that generally do not fit in any other kingdom

Algae

Plantlike protists

Cyanobacteria (blue-green algae)

photosynthetic bacteria, possess the pigment chlorophyll a and use water in their photosynthetic process

Agar

a gel-like polysaccharide compound used for culturing microbes; extracted from certain red algae

Protozoa

one-celled organisms that are more complex than bacteria

Fungi

A kingdom made up of nongreen, eukaryotic organisms that have no means of movement, reproduce by using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients

Molds

multicellular fungimade up of long filaments

Helminths

multicellular parasitic organisms commonly called worms or flukes
