What were he results of the Jahrling's tests with virus samples.

Jahrling did a number of tests. The text evidence can be found below.

"You drop a sample of the virus into the flask, and the virus spreads through the cells. If the virus likes the cells, it will multiply."

"Jahrling explained that he was planning to test the cells with human blood samples that would make them glow if they were infected by Marburg."

The results of the test were that the disease was not Marburg but Ebola Zaire.
