Contrary to the affidavits, the first reports on the 
polyoma virus were published in 1953, not 1960. Dozens of 
papers were written and published by a variety of authors in 
the interim between those two years. 3/ Further, polyoma is 
widely distributed throughout the environment without evidence 
of having infected man. The virus is readily isolated from 
wild mice collected from all over the world and has, interestingly 
enough, been isolated frequently from wild mice collected in 
Frederick County, where the plaintiff lives. 
Repeated attempts have been made to infect laboratory 
cell cultures derived from human tissue, and all such attempts 
have failed to yield virus. Repeated attempts have been 
made to detect antibodies against polyoma virus in the blood 
of laboratory workers exposed to the virus. All such attempts 
have failed. The presence of antibodies in blood samples 
from human beings is a delicate and sensitive test for human 
susceptibility to a given agent. The fact that antibodies 
against polyoma have not been detected in over 300 human 
blood samples from laboratory workers is impressive evidence 
that the virus is not dangerous for man. 
(4) A hazard is created that is alive 
and selfper tpetuat ing and rapidly reproduces. 
Affidavit 1|5. 
The prospect of E^_ coli , Chi 1776, surviving outside of the 
laboratory is negligible. The prospect of Chi 1776 reproducing 
outside of the laboratory is virtually impossible. Chi 1776 
is not selfperpetuating , but rather is a weakened and enfeebled 
genetic mutant selected by microbiologists especially for 
its zero hazard qualities. The organism is so inherently 
delicate that it cannot compete with other native microbial 
inhabitants of the human or animal intestinal tract. It can 
only be grown under special laboratory conditions and cannot 
be "converted" into a pathogen. It just does not have a 
doomsday potential.
