Kwapinski, J. B. (The University of New England, Armidale, N.S.W., Australia). Cytoplasmic antigen relationships among the Actinomycetales. J. Bacteriol. 87:1234-1237. 1964.-Cytoplasm obtained from 44 strains of the Actinomycetales was tested against the homologous and heterologous antisera in a diffusion precipitation test. A pattern of serological relationships among the cytoplasmic fractions...

Clonal relationships among bloodstream isolates of Escherichia coli.

The clonal relationships among 187 bloodstream isolates of Escherichia coli from 179 patients at Boston, Mass., Long Beach, Calif., and Nairobi, Kenya, were determined by multilocus enzyme electrophoresis (MLEE), analysis of polymorphisms associated with the ribosomal operon (ribotyping), and serotyping. MLEE based on 20 enzymes resolved 101 electrophoretic types (ETs), forming five clusters; r...

Antigenic and genomic relationships among turkey and bovine enteric coronaviruses.

Antigenic and genomic relationships among tissue culture-adapted turkey enteric coronavirus (TCV) isolates, three strains of avian infectious bronchitis virus (IBV), and mammalian coronaviruses were investigated. Immunoblotting and immunoprecipitation experiments using polyclonal antisera showed that the four major structural proteins of TCV cross-reacted with the four homologous proteins of bo...

Relationships among antigen presentation, cytokines, immune deviation, and autoimmune disease

I n this issue, Saoudi and colleagues expand on their previous observation that development of experimental allergic encephalitis (EAE) can be suppressed by preimmunizing rats with a myelin basic protein (MBP)-derived peptide that has been coupled to an anti-IgD antibody (1, 2). Their observations illustrate how antigen presentation by a particular cell type can induce a form of tolerance, immu...
