Antigenic Variation and Some Biological Properties of Wild-Type Measles Virus Strain Buk and Vaccine Strain L-16.

In some measles virus strains protein synthesis is restricted or reduced at higher temperature incubation. But in wild-type Buk strain and L-16 vaccine strain no changes in viral protein synthesis at 40 degrees C were shown. Radiolabelled Buk and L-16 proteins were precipitated with reconvalescent sera, vaccinated children's sera, subacute sclerosing panencephalitis patients' sera and rabbit antisera.
