In organizing a symposium the convener is almost invariably confronted with difficult decisions with respect to the subject matter to be encompassed. The difficulties of choosing specific facets of a problem or particular aspects of a relatively broad field are amplified when the symposium must, through temporal limitations, be confined to a matter of several hours rather than several days. In this afternoon's symposium, a comparatively broad coverage of the viral and rickettsial field might have been effected through discussion of the purification of viral and rickettsial agents, cellular metabolism and viral growth, the initiation of cellular infection by viruses and rickettsiae, the pathogenesis, immunity and epidemiology of viral and rickettsial infections, etc., and even of the fascinating subject of the role of the numerous unidentified viruses recovered from arthropods, birds and the human throat and intestinal tract in the causation of disease.
