Question

Extract of Tobacco with Mosaic disease was called contagium vivum fluidum by

• A. Mayer
• B. Ivanowski
• C. Beijerink
• D. Pasteur

Answer 1

The correct option is C Beijerink

Contagium vivum fluid was a phrase first used to describe a virus, and underlined its ability to slip through the finest-mesh filters then available, giving it almost liquid properties. Martinus Beijerinck, a Dutch microbiologist and botanist, first used the term when studying the tobacco mosaic virus, becoming convinced that the virus had a liquid nature.

So, the correct answer is 'Beijerink'.
