SOME PROPERTIES OF ECHO AND COXSACKIE VIRUSES IN TISSUE CULTURE AND VARIATIONS BY HEAT

Abstract

MK, MS, FL and HeLa cells are susceptible to ECHO and Coxsackie B viruses. Some types of viruses do not possess the ability to form plaque under the conditions adopted in this study. The Coxsackie viruses surviving heat treatment has variations as to heat stability in the state of free virus or propagating virus in cells, plaque forming ability and plaque size. The variations are different with the type of viruses.
