Somatic Antigen 15 as a Precursor of Antigen 34 in Salmonella

Nature, 1960
PHAGE ɛ34 is a temperate phage produced by group E 3 Salmonellae with O antigens (3), (15), 34 and capable of converting group E 2 Salmonella (O antigens 3, 15) to group E 3 Salmonella (O antigens (3), (15), 34) by lysogenization1–5. The formation of antigen 34 is accompanied by partial loss of antigens 3 and 155, suggesting a close relationship ...

Somatic antigen addition in salmonella by bacteriophage

Virology, 1957
Abstract A bacteriophage that will lysogenize certain species of Salmonella has been isolated from Salmonella kentucky . This phage confers on the cells which it has lysogenized the ability to produce an added somatic antigenic component. The process of antigen addition, which appears to be dependent on the introduction and presence of the ...

Surface and somatic antigens of Fusiformis nodosus

Journal of Comparative Pathology, 1973
Abstract Fusiformis nodosus produces at least 2 agglutinating antigens during growth on hoof agar plates. One of these is a surface or K antigen that is removed by washing the bacteria in buffered saline or water. In the presence of homologous antiserum prepared in rabbits or sheep, cells with K antigen exhibit a distinctive agglutination that is ...

Somatic generation of antigen-receptor diversity: a reprise

Trends in Immunology, 2001
Thirty years ago, in his inaugural article entitled 'The somatic generation of immune recognition', Niels Jerne put forward the hypothesis that the primary antigen (Ag)-receptor repertoire must be restricted towards self-Ags before Ag-mediated selection.

Induced Somatic Mutations Affecting Erythrocyte Antigens

Science, 1960
The frequency of inagglutinable erythrocytes was increased in pigeons following total body irradiation and in human polycythemic patients treated with P 32 . Persistence of the increased levels of inagglutinable cells was observed in pigeons retested at over 200 days after irradiation and in a polycythemic patient ...

Serological classification of Pseudomonas cepacia by somatic antigen

Journal of Clinical Microbiology, 1986
Ten samples of antiserum against Pseudomonas cepacia were prepared by the intravenous immunization of rabbits with heat-killed organisms. Ten P. cepacia strains used for immunization were proven unique antigenic strains. Using these antisera, we serogrouped 127 strains of P. cepacia, and 114 strains (89.8%) fell under one of the ten serogroup. The most

Analysis by immunoblotting ofToxoplasma gondii exo-antigens and comparison with somatic antigens

Parasitology Research, 1992
Two soluble Toxoplasma gondii antigen preparations were compared using the immunoblotting technique. The first preparation, which is commonly employed in ELISA tests, corresponds to a lytic extract of the parasite. The second known as exo-antigen, has yielded good results in cell immunity research and is obtained from Toxoplasma gondii culture ...

Plasticity Under Somatic Mutation in Antigen Receptors

1998
After antigen binding, a subset of newly activated B and T cells is recruited into the primary follicles of lymphoid tissue where, along with follicular dendritic cells, they establish a site of vigorous lymphocyte proliferation. Within these germinal centers the processes of somatic hypermutation and selection result in the affinity maturation of ...

Capsular and somatic antigens of Klebsiella bacilli.

Archivum immunologiae et therapiae experimentalis, 1990
Capsular and somatic antigens were determined in 100 Kl. oxytoca strains isolated from patients with the respiratory tract inflammations. K antigens were assigned by the capsula swelling test using 77 specific anti-capsular sera. Most frequent were: K14, K2, K55, K8 and K16 antigens.

MHC class I antigens and somatic mutants

Immunology Today, 1987
I read with interest the hypothesis offered by T.V. Rajan to explain a possible role for class I major histo- compatibility complex (MHC) anti- gens in the elimination of somatic mutants (Immunol. Today, 1987, 8, 171). I believe, however, that his con- clusions fail to explain the apparently endless number of tumor-specific transplantation antigens ...
