An antigenic scheme, based on the determination of 17 somatic and 9 flagellar antigens, is proposed for Citrobacter koseri. Seven of the flagellar antigens constituted the specific phase (a through g), and the others (1 and 2) were nonspecific. Of the 238 theoretically possible serotypes, 48 were identified among 680 cultures examined.
Extending observations on the immunogenicity of neo-antigens that arise in the course of oncogenesis and tumor progression, we suggest that somatic mutations affecting normal tissues also lead to generation of new epitopes. We hypothesize that, at least under inflammatory conditions, immune responses against such neo-antigens may lead to the elimination or functional impairment of normal cells,...
escherichia coli o157:h7 is an important human pathogen causing haemorrhagic colitis, haemolyticuraemic syndrom and thrombotic thrombocytopenic purpura. in this study, 100 ground beef samples were collected randomly from beef markets in june 2004. for isolation of the bacteria, samples were firstly enriched in modified trypticase soy broth, followed by plating onto sorbitol macconkey agar suppl...
Species selected from six families of the class Basidiomycetes were evaluated for allergenicity in atopic and nonatopic individuals and for immunogenicity and antigenic cross-reactivity in experimental animals. Between 42% and 68% of atopic asthmatics demonstrated positive Type 1 wheal-and-flare skin reactivity to basidiomycete metabolic and somatic antigens. Sixty-four percent of skin test-pos...
