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)
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)
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)
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)
