Dr. David Figurski Speaks Out About Coronavirus
Donna O’Donnell Figurski
“In graduate school, I worked with a virus that infects bacterial cells (bacteriophage T1). One T1 virus particle takes about 10-12 minutes to break open the E. coli cell and release over 100 new virus particles. Each new particle can infect a cell and produce over a hundred new virus particles. So, 10-12 minutes later, there are 10,000 viruses. I could do some experiments in the morning and have the results that afternoon.
To make stocks of the virus, we would infect a late culture of bacteria. A couple of hours later, all the bacterial cells were broken open, leaving only virus.
Animal viruses, like coronavirus, probably take hours to reproduce, but each infected cell produces at least a thousand new virus particles.
Consequently, I have a healthy respect for viruses.”
