Carrillo J.; Silva Sosa M.; Garcia Tamayo F., 1988: Inhibition of antigenicity of an enterobacterial common hapten by urine from children with cancer. Twenty samples of urine from children with cancer were incubated for 30 minutes with 3.1 .mu.g of an ethanol soluble fraction of Escherichia coli 014 crude lipopolysaccharide in order to investigate the inhibition of antigenicity of an enterobacte...

García Tamayo, F.; Carrillo, J.; Silva Sosa, M., 1989: Enterobacterial common antigen in the urine from children with cancer. An inhibition of immunohemolysis assay was used to detect the enterobacterial common antigen (ECA) in urine samples from 40 children with cancer. Seven patients were excluded because bacterial contamination of urine. Thirty of the remaining 33 ste...

Meier-Dieter, U.; Starman, R.; Barr, K.; Mayer, H.; Rick, P.D., 1990: Biosynthesis of enterobacterial common antigen in Escherichia coli. Biochemical characterization of Tn10 insertion mutants defective in enterobacterial common antigen synthesis. Twelve independent Tn10 insertion mutants of Escherichia coli K12 were isolated that were defective in the synthesis of enterobacterial common antigen (ECA). The mutants were identified by screening a random pool of Tn10 insertion mutants for thei...

Boyd, W.C.; Warshaver, E.R., 1946: Decreased antigenicity of coupled hapten-protein antigen resulting from treatment with too much hapten. Conjugated protein -arsanilic acid antigens prepd. by using 6 times the theoretical amt. of diazotized arsanilic acid proved to be markedly inferior as antigens and no one of 30 rabbits injd. with such an antigen produced more than a trace of anti...

Rinno, J.; Golecki, J.R.; Mayer, H., 1980: Localization of enterobacterial common antigen:immunogenic and nonimmunogenic enterobacterial common antigen-containing Escherichia coli. In rabbits immunized with intact bacteria, the immune response to the enterobacterial common antigen (ECA) predominantly consists of the production of immunoglobulin M antibodies. This is not dependent on whether the animals are immunized for a sh...

We established hybridoma cell lines producing monoclonal antibodies against enterobacterial common antigen (ECA) and a substructure of the outer core of different Escherichia coli lipopolysaccharides (LPSs). Anti-ECA antibodies 865 and 898 reacted...

Griffiths, E.K.; Jewett, T.C., 1976: Duration of antibody responses to common enterobacterial and O antigens of children with pyogenic peritonitis. Children with pyogenic peritonitis folloiwng appendicits produce antibodies against the common enterobacterial antigen (CA) in unusually high titers when compared to patients with salmonellosis, shigellosis, or urinary tract infection. The duratio...
