The below is from Dr Cowan's book Chapter 2. The picture above shows the findings described below.
Here is the essence of Lanka’s experiment, done by an independent professional laboratory that specializes in cell culturing. As seen in this series of photographs, each of the four vertical columns is a separate experiment. The top photo in each column was taken on day one, and the bottom photo was taken on day five.
In vertical column one, normal cells were cultured with normal nu- trient medium and only a small amount of antibiotics. As you can see, on neither day one nor day five was any CPE found; the cells continued their normal, healthy growth.
In vertical column two, normal cells were again grown on normal nutrient medium and a small amount of antibiotics, but this time, 10% fetal calf serum was added to enrich the medium. Still, the cells in the culture grew normally, both on day one and day five.
The third vertical column shows what happened when Dr. Lanka’s group used the same procedures that have been used in every modern isolation experiment of every pathogenic virus that I have seen. This included changing the nutrient medium to “minimal nutrient medi- um”—meaning lowering the percentage of fetal calf serum from the usual 10% to 1%, which lowers the nutrients available for the cells to grow, thereby stressing them—and tripling the antibiotic concentration. As you can see, on day five of the experiment, the characteristic CPE occurred, “proving” the existence and pathogenicity of the virus—ex- cept, at no point was a pathogenic virus added to the culture. This outcome can only mean that the CPE was a result of the way the culture experiment was done and not from any virus.
The fourth and final vertical column is the same as vertical column three, except that to this culture, a solution of pure RNA from yeast was added. This produced the same result as column three, again proving that it is the culture technique—and not a virus—that is causing the CPE.
