immunochemical studies of foot-and-mouth disease. v. antigenic variants of virus demonstrated by immunodiffusion analyses with 19s but not 7s antibodies.three antigenic variants of foot-and-mouth disease virus, type a, strain 119, were demonstrated in ouchterlony analyses utilizing serum collected from guinea pigs 7 days postinfection (dpi). such antisera contain antibodies of the 19s class. guinea pig antisera that contained antibodies of the 7s class were unable to distinguish between the antigenic variants. similarly, 19s antibody was able to demonstrate antigenic differences in trypsin- and chymotrypsin-treated viruses that were not detected ...19694302741

electrophoretic characterization of foot-and-mouth disease virus-specific ribonucleic acid.foot-and-mouth disease virus (fmdv)-specific ribonucleic acid (rna) was analyzed by electrophoresis on 0.5% agarose gels. four classes of rna were resolved as a function of mobility in agarose: two classes of slowly migrating multistranded rna, the infectious viral rna with intermediate mobility, and a minor fast-moving class of lower-molecular-weight single-stranded rna. the major rna species were infectious viral rna and the slowest migrating class of multistranded rna. the latter rna was poly ...19694311799

foot-and-mouth disease virus-induced alterations of baby hamster kidney cell macromolecular biosynthesis: inhibition of ribonucleic acid methylation and stimulation of ribonucleic acid synthesis.the kinetics of ribonucleic acid (rna) and protein synthesis and rna methylation were examined after foot-and-mouth disease virus (fmdv) infection of baby hamster kidney cells. the synthesis of rna extracted from the whole cells was stimulated two- to threefold above the control level of synthesis. this increased rate was attributed to viral rna synthesis. the inhibition of host rna methylation was concomitant with but more pronounced than protein synthesis inhibition. the methylation of transfe ...19704318088

quantitation of the antigenicity and immunogenicity of purified foot-and-mouth disease virus vaccine for swine and steers.the antigenicity and immunogenicity of a purified preparation of foot-and-mouth disease virus [type a(12), strain 119 (fmdv a-119)] inactivated with 6.0 mmn-acetylethylenimine at 37 c were compared in swine and steers. three antigen doses were tested, 640, 160, and 40 ng. in accordance with findings for guinea pigs, as previously determined by dose-response curves, as little as fourfold changes in antigen in the region of the minimum effective dose produced marked differences in the serological ...19704320865
further investigations on the airborne excretion of foot-and-mouth disease virus.calf thyroid tissue cultures were found to be the most sensitive system in detecting virus collected in a large volume air sampler from boxes, where cattle, sheep and pigs infected with a and c strains of foot-and-mouth disease (fmd) virus were housed. it was confirmed with all strains of fmd virus tested that pigs excreted the most virus followed by cattle and sheep, but there was variation between strains, the highest virus recoveries being obtained from animals infected with o(1) and c novill ...19704321594
ihalation, persistence and dispersal f foot-and-mouth disease virus by man.sampling of human subjects, who had been in contact with animals infected with foot-and-mouth disease (fmd) virus, showed that virus could be recovered from the nose, throat, saliva and from air expelled during coughing, sneezing, talking and breathing. the amounts of virus recovered paralleled those collected with a large-volume sampler and multistage impinger and these findings confirmed that the highest recovery of airborne virus was from infected pigs followed by cattle and sheep. more virus ...19704321595

detection of foot-and-mouth disease virus antibodies. i. "passive" hemagglutination test.a passive hemagglutination test has been developed to detect and measure foot-and-mouth disease virus (fmdv) antibody by using glutaraldehyde as a coupling reagent. an optimal concentration of 10 to 40 mug of virus per ml with 0.25% glutaraldehyde at 25 c for 1 hr was established for the sensitization of sheep erythrocytes. a reaction time of 18 hr at 4 c or 2 hr at 37 c induced good agglutination in the presence of specific antibody. sensitization was carried out in phosphate buffer, whereas ag ...19704318573
