CHI I9I-II.A 
UNITED STATES GOVERNMENT 
Memorandum 
to : Herman Lewis 
Senior Scientist for Recombinant ONA 
date: 10-26-77 
from : Mary E. Clutter 
Developmental Biology Program Director 
subject: Consents on the draft revision of the NIH Guidelines 
In general* the revised guidelines are acceptable at this time. 
One problem which should receive attention is the categorization 
of all plant pathogens with class 2 human pathogens, thus 
requiring P3 EK2 containment. The Advisory Committee could not 
deal with this matter adequately because plant pathogens have not 
been classified. Until such time as they are (actually, a con- 
ference could be sponsored to deal with this)* perhaps they should 
be treated on an individual case basis.
