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.

carrier transmitted disease
zoontinic disease

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
