There is a way to estimate the powerfulness of virus. The method is called plaque assay. When you infect a lawn of cells with virus, the site where the virus attaches will have dead cells. The newly synthesized virus will infect the neighbor cells and kill them as well. In several days, you see plaques of dead cells in the lawn of cells. The more plaques you have, the more powerful the virus is.

I was reading an instruction of how to “grow” virus. There were a lot of typos like, instread of “big” dish, “bib” dish. As I read on, I came across “plague assay”.

I suppose that that is a more appropriate name but…it made me feel like I’m very evil.
