microorganisms that colonize a person or animal without usually causing disease (either beneficial or no effect)

growth of pathogenic organisms in the body whether or not body function is impaired

impaired body function; any change from a state in health

noncommunicable disease

caused by a genetic or degenerative process

opportunistic pathogens

require special circumstances to produce disease; one will often cause a variety of infections; are commmonly encountered organisms or ones that you carry with you

able to infect a healthy host under their own power to initiate disease; usually cause one specific disease; are not so commonly encountered and are not carried with you

adherence factors of a pathogen

capsule, fimbriae, surface receptors, hook, viral spikes, use of host cell actin fibers to attach to and then enter the host cell (see pg. 51 for more detail)

virulence exoenzyme; dissolves collagen; softens up tissue so the infection can spread

virulence exoenzyme; dissolves hyaluronic acid; helps infection to spread

released from live bacteria; come from both Gram + and - bacteria; are proteins; more toxic (tiny amounts have a great effect); have specific effects; heat sensitive; antigenic (stimulate an immune response)

are released from dead bacteria; come only from Gram - bacteria; are lipopolysaccharides; less toxic; more generalized effects; note heat sensitive; generally not antigenic; results in the blood: inflammation, low bp, fever, excess clotting, edema

a modified exotoxin used as a vaccine

confined to one area of the body

throughout the body (carried by the blood)

life threatening systemic response to a bacterial infection (usually caused by a Gram - organism, but other microorgansims can cause this)

symptoms of septic shock

swelling (edema) of the face, hands, & feet; low bp and rapid, weak pulse; dyspnea (difficultly breathing); fever; disorientation, confusion, irritability, somnolence (sleepiness)

treatments for septic shock

inject epinephrine; open airway (intubation or tracheostomy); oxygen if needed; restore blood volume with rapid intravenous infusion of isotonic solution; draw blood (blood gases and pathogen isolation); broad sprectrum bacteriostatic drug

Micro Exam #4

Laura's part (disease/pathogens/septic shock)

Question	Answer
normal flora	microorganisms that colonize a person or animal without usually causing disease (either beneficial or no effect)
infection	growth of pathogenic organisms in the body whether or not body function is impaired
disease	impaired body function; any change from a state in health
communicable disease	caused by a pathogen
noncommunicable disease	caused by a genetic or degenerative process
opportunistic pathogens	require special circumstances to produce disease; one will often cause a variety of infections; are commmonly encountered organisms or ones that you carry with you
true pathogens	able to infect a healthy host under their own power to initiate disease; usually cause one specific disease; are not so commonly encountered and are not carried with you
adherence factors of a pathogen	capsule, fimbriae, surface receptors, hook, viral spikes, use of host cell actin fibers to attach to and then enter the host cell (see pg. 51 for more detail)
collagenase	virulence exoenzyme; dissolves collagen; softens up tissue so the infection can spread
hyaluronidase	virulence exoenzyme; dissolves hyaluronic acid; helps infection to spread
exotoxins	released from live bacteria; come from both Gram + and - bacteria; are proteins; more toxic (tiny amounts have a great effect); have specific effects; heat sensitive; antigenic (stimulate an immune response)
endotoxins	are released from dead bacteria; come only from Gram - bacteria; are lipopolysaccharides; less toxic; more generalized effects; note heat sensitive; generally not antigenic; results in the blood: inflammation, low bp, fever, excess clotting, edema
toxoid	a modified exotoxin used as a vaccine
local infection	confined to one area of the body
systemic infection	throughout the body (carried by the blood)
septic shock	life threatening systemic response to a bacterial infection (usually caused by a Gram - organism, but other microorgansims can cause this)
symptoms of septic shock	swelling (edema) of the face, hands, & feet; low bp and rapid, weak pulse; dyspnea (difficultly breathing); fever; disorientation, confusion, irritability, somnolence (sleepiness)
treatments for septic shock	inject epinephrine; open airway (intubation or tracheostomy); oxygen if needed; restore blood volume with rapid intravenous infusion of isotonic solution; draw blood (blood gases and pathogen isolation); broad sprectrum bacteriostatic drug
