When adult amphibian skin harbors populations of the bacterium, janthinobacterium lividum (jl), chytrid infection seems to be inhibited. which of the following represents the best experimental design to test whether this inhibition is real?
a) inoculate uninfected amphibians with jl, and determine whether the amphibians continue to remain uninfected by chytrids.
b) inoculate infected amphibians with jl, and determine whether the amphibians recover from infection by chytrids.
c) take infected amphibians and assign them to two populations. leave one population alone; inoculate the other with jl. measure the rate at which infection proceeds in both populations.
d) take infected amphibians and assign them to two populations. inoculate one population with a high dose of jl; inoculate the other with a low dose of jl. measure the survival frequency in both populations.
