ENTEROVIRUSES IN ALASKA 



dealing with water in which there were actual active organisms, 

 and they were measuring organic content, biological activity, 

 and virus viability very closely. 



WALKER: This stabilizing effect of proteins and certain ions 

 is a fairly well known one that is used and taken advantage of 

 regularly in the laboratory for stabilization of these and other 

 viruses, and is used to prolong storage of viruses, 



NUNGESTER: And bacteria. 



REINHARD: Yes. 



BERRY: Thank you. Dr. Reinhard. I suppose as moderator 

 of this session, it is up to me to summarize everything that 

 has been said this morning. I would not attempt it, really, but 

 I would like to say that on the basis of this opening session, 

 it seems rather clear that there is no evidence whatsoever of 

 any significance that would indicate that arctic environment 

 is particularly predisposing to human diseases of an infectious 

 nature. There are certain unique situations that ari se as a re- 

 sult of the environment that alter housing and in certain groups 

 of people, the natives particularly, the diet. Their prior ex- 

 perience with various microbic agents, and actually these would 

 apply not only in the Arctic, but probably in all other environ- 

 ments and in all other parts of the earth, shows rather clearly 

 that in the human being, cold may or may not be stressful. In 

 fact, the measure of man's adaptation to the arctic environ- 

 ment is his ability to live with minimum stress, and I assume 

 that with minimum stress there is a minimum change and response 

 to bacterial and viral disease.
