Micro final

Spontaneous generation

Living things come from no living things

Miasma

Disease that comes from foul smelling air

Stage

Supports slide

Coarse adjustment

Adjudsts focus under lo power only

Diaphragm

Control the amount if light reaching the specimen

Koch

Proved the germ theory of disease

Hooke

Coined the term cell

Pasteur

Proposed the germ theory of disease

Redi

Disproved spontaneous generation using meat and maggots

Semmelweis

Observed that midwives had less cases of childbed fever than did physicians coming directly form autopsies WASH HANDS

Snow

Along with Semmelweis, suggested that disease was caused by an invisible object in the environment, not miasma. Discovered a source of contaiminated water as the cause of cholera in London.

Van Leeuwenhoek

Used a simple microscope to observe animalcules

Jenner

Observed that when one got cowpox that they did not get smallpox, CREATED VACCINE

Koch’s postulates

Related a single MO to a single disease

Prokaryotic

No nucleus

Eukaryotic

Nucleus

2 kingdoms and their cells

Eubacteria -kingdom …. Prokaryotic

Archae bacteria - kingdom….. prokaryotic

Total magnification

Calculate by multiplying the eyepiece by the objective lense

Why is immersion oil used instead of vegetable oil

Same RI as the microscope slide

Gram positive

Stains purple, and has more peptidoglycon in its cell (why it turns purple)

Staphylo

Clusters

Coccus

Balls

Strepto

Lines or strips

Bacillus

Pill like

Vibrio

Appear like beans with a crescent shape

Logarithmic

Bacteria is reproducing *symptoms

Bacterial growth curve

Lag—-log—-stationary——decline

Stationary

When death rate is equal to reproductive rate

Thermophiles

Love heat

Mesophiles

20-40 most human pathogens

Psychrophiles

Cold loving

Acidophiles

Acid loving

Neutrophiles

Neutral PH

Halophiles

Salt loving

Facultative anaerobes

Prefer no oxygen but can grow with oxygen

Faculattive aerobes

Prefer oxygen but can grow without

Obligate anaerobes

No oxygen killed by it

Hypertonic

When water leaves the cell, making the cell shrink

Streak plate method purpose

To get a pure culture

Glucose —— 2 Peruvian acid + 2ATP

Makes

I I

YEAST Muscle cells

I. I

Ethyl alcohol. LACTIC ACID

Fredrick Griffiths experiment

Realized the R strain transformed into S strain

Infection

Invasion of body tissues

Etiology

Study of the cause of disease

Virulence

The degree of damage a pathogen causes on host

Epidemiology

Study of transmission spread control and prevention of infectious diseases

Epidemic

Sudden outbreak above typical level

Reservoir

Where pathogens persist/found

Carrier

An individual who shelters a pathogen and spreads it

Vector

A live animal that transmits a MO around

Vehicle

An object or non living thing that transmits microbes

Sterilization

Destruction of all forms of life

Pasteurization

Reduces MO in liquids

Disinfectant

Removes bacteria from objects

Antiseptic

Remove pathogens from tissues

Septicemia

MO infection of the blood

Sanitize

Reduce # of MO to a safe level
