Pathogenic Micro BC Flashcards
Parasitism
Interaction in which microbes are benefited and humans are harmed
Human body
10^13 cells 10^14 bacteria
Prokaryotes
Eubacteria and archaebacteria (environmental)
Eukaryotes
Fungi and parasites
Not cell
Virus and prion
Infection
the invasion of an organism’ body tissues by disease causing agents
Disease
any deviation from the normal structural or functional state of an organism
Etiological agent
a viable microorganism or its toxin that causes disease in humans
Pathogen
a microorganism that causes or can cause disease
Pathogenicity
the capacity of a microbe to cause damage in the host
Virulence
the ability of a microorganism to cause disease in the host
Incubation period
the moment of exposure to an infectious agent until symptoms of the disease appear
Mobility rate
the capacity of movement
Mortality rate
the measure of the number of deaths by a pathogen
Opportunistic Pathogen
organisms that normally do not affect a healthy host
Prophylaxis
action is taken to prevent disease
Antigen
any substance that causes your immune system to produce antibodies
Antibodies
(Ig) the protein produced by plasma cells after stimulation of an antigen
Immunity
the ability to recognize self cells from nonself cells
Light bright field microscopy
view fixed and live specimens that have been stained with basics stains that give contrast
Fluorescent microscopy
high sensitivity, ability to label specific molecules and structures of interest
Enriched nonselective media
supports the growth of most organisms
Selective media
recovery of specific organisms and suppresses the growth of unwanted bugs
Differential media
allow identification of organisms in a mixture
