Resumo: Chikungunya virus vaccines prepared by Tween 80 - ether inactivation of virus grown in green monkey kidney cell cultures were shown to be as immunogenic as comparable Formalin-inactivated vaccines. Both types of vaccine stimulated hemagglutination-inhibiting, complement-fixing, - neutralizing antibody - afforded protection to mice against a live virus challenge. It was shown after Tween-ether treatment of chikungunya virus that the infectivity of the virus was lost - the hemagglutinin titer was increased. By characterization of the resultant hemagglutinin by sucrose - cesium chloride density gradient centrifugation, it was found that the extracted particle was smaller in size - greater in density than the parent virus particle. Removal of lipid may account for the alterations in the physical characteristics of the infectious virus particle. Conditions for treatment of chikungunya virus with Tween - ether were found that preserved high titers of hemagglutinin as well as the immunogenicity of the virus preparations.
