Two monoclonal antibodies specific for lipopolysaccharide antigens of Xanthomonas campestris pv. begoniae and pv. pelargonii reacted with all of their respective pathovar strains and not with 130 strains of other xanthomonads or 89 nonxanthomonads tested. These results, as well as previous results, indicate that pathovar-specific monoclonal antibodies were(More)
Strains of Listeria monocytogenes serotype 4b account for a large fraction of sporadic listeriosis cases, as well as all major food-borne epidemics attributed to this pathogen. We have identified a set of three monoclonal antibodies which showed a high degree of specificity for strains of L. monocytogenes serotype 4b. Two of these antibodies (c74.33 and(More)
The first chicken immunoglobulin light (L) chain allotypic specificity (L-1.1) to be described that was present on IgM, 7S Ig, Fab, and L chains was detected by radioimmunoassay. The gene controlling the expression of L-1.1 is inherited in a simple Mendelian fashion at an autosomal locus and is unlinked to a constant region heavy chain locus, four blood(More)
Blood serum levels of 7S Ig appear to be a highly heritable (h2=0.76) trait. A possibly weak association of high 7S Ig with the phenotype of inherited muscular dystrophy is noted. In contrast to a previous study (Sanders and Kline 1977), our survey of 4 comparisons in paired lines showed dystrophics with slightly elevated 7S Ig levels and no differences in(More)
