Ecology of Disease; Ch. 52.3; Ch. 57.3 Flashcards
atypical conditions in living organisms that cause some sort of physiological impairment
Disease
the transfer of diseases among different individuals of the same generation
Horizontal Transfer
transfer of a disease from parent to offspring
Vertical Transmission
response to an initial antigen exposure
Primary immune response
rapid and heightened production of additional specific antibodies against a specific antigen
Secondary immune response
immune systems ability to produce this secondary response
Immunological memory
adaptive response to exposure to any type of antigen
Active Immunity
small quantities of living, dead, or altered microbes, small quantities of toxins, or harmless antigenic molecules derived from pathogen or its toxins are injected into the body, resulting in a primary immune response, including the production of memory cells
Vaccinations
type of adaptive immunity confers protection against disease through the direct transfer of antibodies from one individual to another
Passive Immunity
highly specific and pure antibodies
Monoclonal antibodies
agents that cause disease symptoms in their hosts
Pathogens
a pathogen will eventually die out within a population when a certain percentage of individuals become immune to the pathogen
Herd Immunity
viruses that have spread from animals to humans
Zoonotic Viruses
