Disease Ecology

This type of pathogen typically resides in one or more nonhuman vertebrates from which is transmitted to a human

• animal borne

• zootrophic

• zoonotic

• zoophilic

Vertebrates that maintain and amplify the pathogen in nature and thus become the source of infection when it spreads to other hosts are known as...

• carriers

• reservoirs

• vectors

• supporters

A type of pathogen that moves from one host to another during the bite of a blood feeding arthropod.

• vector borne disease

• carrier transmitted disease

• zoontinic disease

• pathogenic disease

An infectious diseases that appear suddenly or increase dramatically in incidence is known as a/an...

• unknown disease

• emergent disease

• divergent disease

• convergent disease

Term used for when a virus shifts it's host range, like AIDS going from apes to humans.

• resinous jumping

• people jumping

• host jumping

• vector jumping

Disease is an example of what type of limiting factor?

• density independent

• population enhancer

• density dependent

• population exploder

Almost 70% of all emergent disease can be described as.

• zoonotic

• deadly

• entropic

• topographic

Disease is an important factor in all populations because they help...

• help control population size

• help control population density

• slow population growth

• all of the above

How can global warming effect pathogen distribution?

• causes organisms to move to due to environmental changes in temperature

• all viruses fair better in warmer weather

• the hot air causes disease to rise and spread around the globe

• since the cold controls bacterial growth warm weather removes their carrying capacities

STDs can limit population sizes by...

• causing a number of affected organisms to die off

• causing infertility

• causing sterility

• all of the above
