Attempts were made to purify bovine viral diarrhea virus by chromatography on Crotalaria juncea lectin coupled to Sepharose 2B. A recovery of abut 65% of viral infectivity after desorption was obtained. Electron microscopy revealed mostly de-enveloped particles, rather uniform in appearance but differing in size. Immunodiffusion tests with immune calf sera showed precipitation lines of identity between the desorbed virus and extracts from infected cell cultures.
