3.1

Studies and investigates health related matters

recieve call, gather initial info, facility extends full invitation, arrives and conducts additional testing, analyzes info and conducts risk factors, reccomend steps for prevention, implement recs, make adjustments as needed

microorganisms in a particular environment

Disease occurs suddenly and irregularly

Infection acquired in hospital

Sudden increase of a disease in a localized area

Disease present in a community/population

Endemic that spreads past multiple boarders

Disease causing organism invades and grows in another host

Organism where another organism lives

Disease- causing organism (ex: bacteria)

Infection impairs bodily function

How easy a disease is to catch

easy to catch

harder to catch

Bacteria that lives in and on us

Tiny agents

nonliving, submicroscopic, bad protien

Through infected meat and medical equiptment

Protiens in brain fold abnormally

Through MRI, EEG, cerebrospinal fluid analysis

Mad cow disease (dementia, psychosis, coma)

nonliving, submicroscopic, outer protien shell

physical exam and labs

touch, saliva, blood, sexual contact

Antivirals

Infect and take over host cells protien synthesis process

living, microscopic, unicellular prokaryotic organism

Invade cells causing tissue damage, producing toxins

through orfice (nose and mouth), wound, normal flora imbalance

Lab tests and physical exam

Antibiotics

tuberculosis (cough, chest pain, coughing up blood)

living, microscopic, single celled eukaryotic animal like organism

Deprive organs of essential nutrients and cause organ and tissue damage

Through contaminated food/water with feces from infected organism

Examine fecal material for protists

Antiprotozoal

giardiasis (parasites in shells outside intestines)

living, multicellular, eukaryote like yeast

Cause tissue damage

tissue exam of infected area

Antifungals

athletes foot

living, multicellular, eukaryotic worms- micro OR macroscopic

Deprive host of nutrients in food causing tissue and organ damage

Contaminated food/water

Microscopic exam of fecal material

deworming medications

tape worms (nausea, weight loss, abdominal pain)

Person vulnerable to infection

reservoir, previous location

Prions, bacteria

People, animals

GI Tract, Respritory system, skin

direct, indirect

host touches infected person, exposed to bodily fluids

Host inhales infected particles, touches infected object, or is bitten by an infected insect

# of organism it takes to cause illness following exposure

less needed, stronger the virus

M, S, and E protien

Lining of air sacs and blood vessles around them become damaged (oxygen is blocked by fluid)

nonspecific defense your born with (tears, stomach acid, fever, inflammation)

Specific defense aquired over time, respond to certain antigens

Aquired from getting the disease or a vaccine

Aquired from mother (placenta and breast feeding)

Innate, acquired, active, passive, natural, artificial

built from getting the disease

built from getting the vaccine

Most people in community get a vaccine, so non vacc are also protected

term to measure how infectious an agent is

type of WBC the body sends to kill infection

type of WBC that builds antibodies to the disease

1 sick person on average will infect less than 1 person

1 sick person on average will infect 1 person

1 sick person on average will infect indicated amount

infectious dose

lower, better, less

Cause of disease or condition

the way they grow, their morphology, shape of cells and their ability to metabolize

Clear container used to culture bacteria

groups bacteria grow in

Bacteria repeatidly divides resulting in colonies

Process of preventing contamination

Bacterias shape

Isolating bacteria

Form, elevation, margin

Foreign material that invades the body

Protiens that aid in destroying infectious agents

Virus where genetic info is stored as RNA instead of DNA

They can cross special barriers

How bacteria is named

Comma shaped bacteria

Gram positive

Gram negative

thin cell wall, two cell membranes, pink/red, 1 layer peptidoglycan

Thick cell wall, 1 cell membrane, multiple layers of peptidoglycan
