Unit 3 - Microbiology (Infection, Chain of Infection, Groups of Microbes, Bacterial Diseases) Flashcards
Condition that results when microbe is able to invade, multiply, and cause injurious effects/ disease
Infection
Short duration
Acute
Long duration
chronic
Comes and goes
Latent
Affects weakened immune system
Usually caused by non-pathogenic organisms
Opportunistic
what type of infection?
cold sores
genital herpes
latent
what type of infection?
cold
acute
type of infection that lasts more than 3 months or a life time
chronic
Chickenpox AKA ?
Varcella Zonster
examples of opportunistic bacteria
staphylococcus aureus
e-coli
candida
What is the chain of infection?
Virtulence
> # of microbes
> susceptible host
> portal of entry
degree of strength of that organism in its ability to produce disease
Virtulence
bacteria that is always on skin and is a common cause for nosocomial infections
Opportunistic bacteria
Staphylococcus aereus
Originating in a hospital
Nosocomial
Found naturally in the intestine
- causes vomiting, cramps, and can affect kidney
Opportunistic bacteria
E-coli
Naturally occurring yeast in gut
Opportunistic bacteria
Candida
Harmless bacteria on the skin
Normal Flora
Which tools help minimize bioburden on surfaces which reduces number of microbes in aerosol?
Dental Dam
HVE
Portals of entry (transmission)
Mouth - airborne
Parental - Blood borne
through mucous membranes or nose/oral cavity
Infection that can be spread from one person to another from contact w/ body fluids
Contagious
Communicable Diseases
Incapable of causing disease under normal circumstances
Nonpathogenic
Disease producing organisms
Pathogens
Single celled microbe
Large variety considered “normal flora”
Bacteria
