Terminology
When a parasite is multiplying in/on a host
What is an infection?
A protein that affects the nervous system
What are neurotoxins?
What is Virus Replication?
The time between exposure and symptoms
What is the Incubation Period?
What is a fomite?
An organisms ability to cause disease
What is pathogenicity?
A protein that inhibits protein synthesis or causes damages to a plasma membrane
What are cytotoxins?
This virus prolongs its stay in the host cell by regulating cell division
What is HPV?
Stage of infection where early symptoms present
What is the Prodromal Stage?
3 factors affecting virulence
What are the Infectivity, Invasiveness, Pathogenic Potential
Ability of an organism to cause symptoms
What is pathogenic potential?
A protein that causes similar response to endotoxins, example is Toxic Shock Syndrome
What are superantigens?
This virus evades the immune system by preventing Class I MHC from reaching the cell surface
What is herpes virus?
Most infections are not severe, insead they are __
What are subclinical?
Most infections are not severe, insead they are __
What is subclinical?
When someone visits the doctor expressing a cough and rash
What is signs?
An example of this protein can be E. coli stopping the uptake of H2O in the intestines, ultimately causing diarrhea
What are Enterotoxins?
Cytomegalovirus puts this molecule up on cell surfaces in order to evade the immune system
What is sham MHC?
What is Disease Syndrome?
Damage due to toxins produced by microbe outside of host's body entering host
What is Intoxication?
A particular organism is able to enter and begin spreading within the host. This organism can do this by breaking down connections between cells, breaking down tissues, or tricking host cells.
What is Invasiveness?
An individual presents at the Emergency Room with the following symptoms/signs: fever, decreased blood pressure, intestinal hemorrhaging and diarrhea. After some time passes, the individual's organs begin shutting down due to disseminated intravascular coagulation.
What are endotoxins

An individual presents at the doctor's office explaining flu-like symptoms/signs. When the doctor asks how long this has been going on for, she said about 1 week. She stated her symptoms are getting better, but still has an occasional stuffy nose and sore throat. What stage of the illness is she likely in?
Convalescent
A particular microbe has an antibody, IgA, bound to it. The role of IgA is to neutralize the microbe it is bound to. Plot twist, the microbe was able to cleave the IgA off of it and continue causing havoc in the host! How did it do this?
IgA Protease
