What hypotheses were supported through not only David Blehert's initial experiment, but also by the follow-up experiments both he and his colleagues conducted?

The fungus can be transmitted through contact and the fungus is deadly to bats.

Explanation:

David Blehert was a scientist who had received a PhD in the field of bacteriology.

David Blehert's hypothesis provided evidence that white-nose fungi were capable of causing death in bats. Even exposure of healthy bats to the bats which were infected with white-nose fungi caused illness and even death of the previously healthy bats.

David Blehert's hypothesis was also supported by other people who conducted the experiments and hence, was considered to be true.
