27 nov 1989 - Electron Microscope Results

Description:

On November 27th, the electron microscope was examined ten days after the virus sample had been set in it. In the meantime, five more monkeys had died at Reston and the disease had been rapidly spreading within it. Under the electron microscope, the cells of the ill monkey appeared to have been blown apart and filled with worm-like structures wall to wall. Only one type of virus has this appearance, a filovirus. The scientist, named Tom Geisbert, who initially saw the electron microscope's results knew what it was and concluded it was the Marburg virus, fatal to both monkeys and humans.

Tom printed out the pictures of the monkey cell's worm-like structures in negative and showed them to his boss, Peter Jahrling, both of who had sniffed the virus sample. It was noticed that the shape of the worms was slightly different than Marburg. His boss then notified military command of the findings, namely Colonel Clarence J. Peters chief of disease assessment. Advised by Colonel Clarence Peters, Tom Geisbert and Peter Jahrling would continue testing the virus sample, using their own blood, to deduce whether or not it was a filovirus.
