Abstract

Horzinek, Marian (Tierärztliche Hochschule, Hannover, West Germany). Characterization of hog cholera virus. I. Determination of buoyant density. J. Bacteriol. 92: 1723–1726. 1966.—Hog cholera virus was subjected to cesium chloride density gradient centrifugation. Most of the infectious activity was detected in fractions with densities between 1.15 and 1.20 g/ml, with a peak at 1.16 g/ml. Infectivity was assayed by use of either the exaltation of Newcastle disease virus method or the hemagglutination exaltation and inhibition of cytopathic effect method.
