Cultures of bovine kidney (BK) cells infected with temperature-sensitive (ts) mutants of foot-and-mouth disease virus (FMDV) were incubated at 38.5 degrees C, a temperature nonpermissive for mutant virus growth and RNA synthesis. The cells were subse

Mice treated with divinyl ether-maleic anhydride (DVE/MA) 7 days before, 2 days before, or simultaneously with foot-and-mouth disease (FMD) viral antigens (aqueous or oil emulsified) were more resistant to virus infection and released antibody earlie

The early response of infant mice to foot-and-mouth disease viral antigens, measured by greater resistance and increased serum-neutralizing antibody, was enhanced by divinyl ether-maleic anhydride (DVE/MA). Preparations of known antigen concentration

A temperature-sensitive (ts) mutant of foot-and-mouth disease virus (FMDV) did not produce RNA polymerase activity nor synthesize viral RNA when incubated in cells solely at the nonpermissive temperature (38.5° C). Infected cells initially incubated

Three temperature-sensitive (ts) mutants of foot-and-mouth disease virus were classified as ribonucleic acid negative and as belonging to the same complementation group when measured by virus yields and [3H] uridine incorporation in paired, mixed inf

Simultaneous injection of divinyl ether-maleic amhydride (DVE/MA) or itaconic-acrylic acid and foot-and-mouth disease virus vaccine enhanced the survival of infant mice to subsequent injections of virus. This enhanced resistance was obtained even wit
