Because 7S immunoglobulin (Ig) G antibodies of low type specificity were present in mixtures with highly specific 19S IgM antibodies, many bovine antisera to foot-and-mouth disease virus (FMDV) type A(12), strain 119 cross-reacted with type O of FMDV and to some degree with type C in the passive hemagglutination (HA) test. After 19S IgM antibodies were(More)
Lampreys and hagfishes are the sole extant representatives of the early agnathan (jawless) vertebrates. We compared retinal function of fully metamorphosed, immature Mordacia mordax (which are about to commence parasitic feeding) with those of sexually mature individuals of its non-parasitic derivative Mpraecox We focused on elucidating the retinal(More)
Equilibrium sedimentation in caesium chloride has been used to separate and study the biologically active components of vesicular stomatitis virus (Indiana) grown in baby hamster kidney cells and chick embryos. Infective egg fluid was shown to contain two infective components of densities 1.191 g/ml. and 1.217 g/ml. A peak of complementfixing activity was(More)
Polyethylene glycol (PEG) and dextran (DEX) were shown to be good selective précipitants of high molecular weight proteins and foot-and-mouth disease antibodies in bovine and porcine sera. Although PEG was less selective than DEX for 19S γM antibodies, the DEX precipitated at most, 60 to 90% of this protein. After two DEX precipitations and two density(More)
Velocity sedimentation in sucrose density gradients has been used to separate and study the biologically active components of vesicular stomatitis (Indiana) grown in baby hamster kidney cells (VSV-BHK) and chick embryos (VSV-CE). If the main infective component in VSV-CE is given a sedimentation coefficient of 625 S, then another infective component of(More)
In addition to currently used serological tests for the occurrence of foot-and-mouth disease virus (FMDV), a specific "passive" hemagglutination-inhibition (HAI) test has been developed as a supplement. Serial twofold dilutions of antiserum (0.05 ml) were mixed with 0.05 ml of a constant concentration of FMDV. After incubating for 30 min at 37 C,(More)
Very few studies have described brain scaling in vertebrates throughout ontogeny and none in lampreys, one of the two surviving groups of the early agnathan (jawless) stage in vertebrate evolution. The life cycle of anadromous parasitic lampreys comprises two divergent trophic phases, firstly filter-feeding as larvae in freshwater and secondly parasitism as(More)
Evidence has been presented for the presence of a 30 to 40 S infective component in vesicular stomatitis virus preparations. It was found to have a low buoyant density (1.05 g/ml), relatively large size and could multiply in BHK cells to produce complete vesicular stomatitis virus, which suggests that it consists of 625S infective particles (major(More)
