Abstract

Summary

In naturally occurring strains and laboratory selected variants of echovirus type 9, the association between virulence for infant mice (v) and the reproductive capacity at 40° (t) was of the vt and vt types. By different selection methods the two other marker combinations, vt and vt, were obtained. The frequency of t in a t echovirus type 9 population was 10. Of the four possible combinations between the v and c (cytopathic effect for human epithelial cell lines) markers, only three were found. The vc covariation could not be obtained in spite of appropriate methods of selection.
