commensal bacterium
may also be an opportunistic pathogen
describes a disease that is always present in a population
endemic
bacteria growing in the blood
septicemia
if a prodromal period exists for a certain disease it should occur prior to
illness
a needlestick is an ex of
indirect contact transmission by fomite
disease in which the causative agent remains inactive before producing symptoms is
latent
the science that deal with when diseases occur and how they are transmitted is called
epidemiology
symptoms of disease differ from signs of disease in that symptoms
are changes felt by the patient
transient microbiota differ from normal microbiota in that transient microbiota
are present for a relatively short time
koch observed bacteria multiplying in the blood of cattle. what is this condition called
septicemia
focal infections initially start as
local infections
some microbes can alter their surface molecules and evade destruction by the host’s immune
antigenic variation
the ID50 is
dose that will infect 50% of test population
all of the following contribute to a pathogen’s invasiveness EXCEPT
toxins
superantigens produce intense immune responses by stimulating lymphocytes to produce
cytokines
antibiotivs can lead to septic shock if used to treat
gram neg bacterial infections
type of relationship in which one organism benefits but not at the expense of the other
commensalistic
type of transmission that includes droplet
direct
type of epidemiological approach that involves studying a disease group and a healthy group
analytical
_______ bind to receptors on host cells
adhesion
made by S. pyogenes that resist phagocytosis
M protein
enzymes made by some bacteria that helps the blood to clot
coagulase
made by gram pot bacteria and are very toxic
exotoxin
produced by gram neg cell when it dies
endotoxin
C. botilinum toxin is an ex of this type of toxin
neurotoxin
