Abstract
Summary
A method for the concentration of Coxsackie virus from dilute suspension is described. This flocculation procedure is capable of detecting as little as 0.00625 LD50/0.02 ml in the starting material and is shown to be more sensitive than an ion-exchange method currently used. It possesses the additional advantages of being economical and simple in execution.
We are indebted to Dr. E. K. Harris for the statistical analyses contained in this paper and to Mr. Richard A. Gallagher for competent technical assistance.
