MBI 111 Exam 1 || with Complete Solutions.
True Pathogen correct answers Microbes capable of causing disease in healthy people with
normal immune defenses
Opportunistic Pathogens correct answers Microbes capable of causing disease when the hosts
defenses are compromised or normal microbiota that causes disease after entering part of the
body where they do not belong
Infectious Dose correct answers Minimum number of microbes required to cause an infection in
a hose (ranges from one cell to billions of cells depending on microbial type)
Acute Infection correct answers Infection that develops quickly, with sever but short-lived
effects
Chronic Infection correct answers Infection the progresses and persists over long period of time
Communicable Disease correct answers Disease in which the pathogen spread from one host to
another, directly or indirectly
Contagious Disease correct answers Communicable disease in which the pathogen is EASILY
spread from host to host
Non-communicable Disease correct answers Disease that does not spread from host to host
Latent Disease correct answers Occurs when a disease causing agent remains inactive in the
body for long periods, but then becomes active to cause disease
Sequelae correct answers Long term of permanent damage to tissues or organs following a
disease
Etiology correct answers Cause of a disease
Subclinical Infection correct answers Infection that exists with no symptoms of disease
Endogenous Infection correct answers Infection caused by normal microbiota (usually in a body
site in which they are not normally found or in an immune compromised host)
Exogenous Infection correct answers Infection caused by pathogenic microbes that originate
outside the hosts body
Localized Infection correct answers Invading microbes are limited to a relatively small area of
the body
Systemic Infection correct answers Invading microbes or microbial products spread throughout
the body
, Focal Infection correct answers Invading microbes "breaks loose" from a localized infection and
are carried to other tissues
Mixed Infection correct answers Infection that involves more than one type of pathogenic
mircobe
Sporadic Disease correct answers Disease that occurs occasionally
Endemic Disease correct answers Disease occurring at some (more or less) constant or expected
level in a population
Epidemic Disease correct answers Occurrence of a disease in excess of the endemic level (in
excess of the normal or expected level)
Pandemic Disease correct answers Worldwide epidemic
Incidence correct answers Number of new cases of a disease occurring in a given population
during a given time period
Prevalence correct answers Number of cases of a disease present in a given population at a given
point in time
Symptons correct answers Changes in the body function not apparent to others
Signs correct answers Changes in body function a health care worker can measure and/or
observe
Syndrome correct answers Specific group of signs and symptoms that always accompany a
particular disease
Healthcare associated Infection correct answers Infection acquired or that develops during a stay
in a hospital (or health care facility)
Microbes and Humans live together in 3 ways: correct answers Commensalism
Mutualism
Parasitism
Commensalism correct answers One organism benefits, other if unaffected
Mutualism correct answers Both organisms benefit
Parasitism correct answers Organism benefits @ expense of the other
Scientists involved in _____ study the complex interactions of protective substances and cells
produced in response to microbial infection correct answers Immunology
