|
Hereditary defects that interfere with normal function are usually self-limiting. What does "self-limiting" mean?
|
the animal affected has a reduced chance of survival.
|
|
|
Category of disease that is passed from one organism to another (bacteria, protozoa, viruses, metazoans).
Congenital Degenerative Hereditary Infectious Parasitic |
Infectious
|
|
|
Category of disease that is due to infection by protozoan or metazoan
Congenital Degenerative Infectious Parasitic Toxic/Exogenous |
Parasitic
|
|
|
Category of disease that involves poisons which act on organisms by injuring local tissue, destroying epithelial cells, or upsetting metabolic functions.
Congenital Deficiency Infectious Parasitic Toxic/Exogenous |
Toxic/Exogenous
|
|
|
Category of disease brought on by changes due to severe short-term or prolonged stress
Degenerative Infectious Parasitic Physiological Toxic/Exogenous |
Physiological
|
|
|
Category of disease brought on by disorders caused by inadequate nutrition (such as poor diet quality, interference with intake or absorption, increased excretion, or pregnancy/lactation)
Congenital Deficiency Degenerative Infectious Parasitic |
Deficiency
|
|
|
Category of disease that exists at birth
Congenital Deficiency Degenerative Hereditary Infectious |
Congenital
|
|
|
Category of disease that is passed from parent to offspring genetically and can be latent
Congenital Degenerative Hereditary Infectious Toxic/Exogenous |
Hereditary
|
|
|
Category of disease that causes a slow “wasting away” of host, with infection being long-term/chronic
Deficiency Degenerative Infectious Parasitic Toxic/Exogenous |
Degenerative
|
|

the anatomic or functional manifestations of disease, studied from the molecular level to the population level
Immunology Microbiology Pathology Virology |
Pathology

|
What is special about the black-footed ferret (Mustela nigripes)?
|
it may be the rarest mammal in the U.S. and the entire world
|
|
|
What are some reasons that wildlife managers should have basic knowledge about disease?
|
1. To provide information to pathologists that will assist in making diagnoses.
2. Important for public relations (reported knowledge can enhance the stature of the agency) 3. To monitor the health of the habitat 4. To detect zoonotic diseases 5. Disease plays a role in population management 6. Disease can impact economy (especially livestock) |
|
|
Why is predation such an important ecological component of disease?
|
sick animals are culled through predation, which reduces the spread of illness to healthy populations
|
|
|
What are some reasons that it is important to study wildlife diseases?
|
1. Animals may serve as reservoirs or vectors for pathogens.
2. Decreasing habitats and population density can predispose animals to disease. 3. Disease could cause serious losses to already endangered species 4. Disease is part of wildlife management (as are food habits, population dynamics, and habitat requirements) 5. Disease impacts hunters. 6. Disease affects predation. |
|
|
What is the ideal habitat for snails?
|
heavy clay soil that limits water drainage
|
|
|
The sheep/cattle liver fluke (Fasciola hepatica) utilizes what creature as an intermediate host?
|
the snail
|
|
|
The geographic range of disease carrying vectors can be either __________ (e.g. along a shoreline or edge of a pond) or __________ (e.g. distances less than 2 m above the surface).
|
horizontal / vertical
|
|
|
Vectors are important carriers of disease, because when the geographic range of vectors coincides with that of the host ___________ are possible.
enzootics epizootics zoonosis |
epizootics
|
|
|
While a pathogen might infect 2 or more species of hosts, the pathology incurred by the parasite may be more significant in one host than in another.
True or False |
True
|
|
|
Controlling one factor for disease may cause another detrimental factor to come into play.
True or False |
