antigenic heterogeneity of the non-serogroup antigen structure of neisseria gonorrhoeae lipopolysaccharides.studies of the antigenic structure of the polysaccharide component of gonococcal lipopolysaccaride (lps) indicated that the non-serogroup antigen structure is antigenically heterogeneous. immunodiffusion studies of gc4 strain 8551 indicated that in addition to the gc serogroup determinent, this polysaccharide contains two other sets of determinants, one which is shared with the other five gc serogroups and a second which is shared by the gc1 and gc3 serogroups. enzyme-linked immunosorbent assay ...197993575
abortive expression of the epstein-barr virus (ebv) cycle in a variety of ebv dna-containing cell lines, as reflected by nucleic acid hybridization in situ.a variety of epstein-barr virus (ebv) dna-containing cell lines have been tested for the expression of the ebv-associated antigens ebna (nuclear antigen), ea (early antigen), and vca (viral capsid antigen), and for the presence of cells containing disproportionate amounts of ebv dna. the antigen tests utilized immunofluorescence and 125i-labelled antibodies combined with autoradiography. ebv-dna was detected by in situ hybridization with 3h-labelled ebv rna complementary to p3hr-1 ebv dna (p-ebv ...197993584
characteristics and genetic control of nk-cell-mediated cytotoxicity activated by naturally acquired infection in the mouse.most and perhaps all natural-cell-mediated cytotoxicity (ncmc) may be activated by a response to exogenous infections. specific-pathogen-free (spf) mice have little or no natural killer (nk) cell activity, but when they are relocated in conventional conditions, they develop strong ncmc within 2 to 3 days. unlike other spf animals, hypothymic nude mice display good ncmc which is further augmented upon their entry into a pathogenic environment. the ontogeny, genetic control and other features of p ...197993585
