Lack of the α-1,2-linked N-acetyl-D-glucosamine epitope in the outer core structures of lipopolysaccharides from certain O serogroups and subspecies of Salmonella enterica

A total of 176 strains of Salmonella enterica representing 116 serotypes were tested for the presence of the T6 epitope of the α-1,2-linked N-acetyl-D-glucosamine residue by reaction with a murine monoclonal antibody T6 specific for this structure in the Salmonella Ra core lipopolysaccharide (LPS)....

description A total of 176 strains of Salmonella enterica representing 116 serotypes were tested for the presence of the T6 epitope of the α-1,2-linked N-acetyl-D-glucosamine residue by reaction with a murine monoclonal antibody T6 specific for this structure in the Salmonella Ra core lipopolysaccharide (LPS). All 20 serotypes (70 strains) belonging to serogroups A to E were positive for the T6 epitope while 29% of the 96 serotypes (106 strains) belonging to O serogroups F to 67 were negative; 12 serotypes (12 strains) of subspecies IIIb Salmonella were positive for the T6 epitope, but 10 serotypes (11 strains) of subspecies IIIa Salmonella were found to lack this epitope. In T6-positive strains, the epitope was accessible to antibody binding in both the unsubstituted free rough core LPS and in the rough core LPS substituted with a few repeating units of O side chains. The presence or absence of the T6 epitope in Salmonella strains was not affected by culture conditions, the source of the isolate, the age of the culture or the presence of fimbriae antigens. La présence de l'épitope T6 du résidu N-acétyl-D-glucosamine lié en α-1,2 a été recherchée chez 176 souches de Salmonella enterica représentant 116 sérotypes, à l'aide d'un anticorps monoclonal murin T6 spécifique de cette structure du ⪡core⪢ du lipopolyoside (LPS) de Salmonella Ra. Les 20 sérotypes (70 souches) appartenant aux sérogroupes A et E sont T6-positifs, tandis que 29% des 96 sérotypes (106 souches) appartenant aux sérogroupes F à 67 sont négatifs. Douze sérotypes (12 souches) de Salmonella sous-espèces III b testés sont T6-positifs mais 10 sérotypes (11 souches) de la sous-espèce III a examinés n'ont pas l'épitope T6. Chez les souches T6-positives, l'épitope est accessible à l'anticorps à la fois dans le core du LPS (rugueux) libre, non substitué, et dans le core du LPS substitué en quelques unités répétitrices des chaînes O latérales. La présence ou l'absence de l'épitope T6 chez Salmonella n'est pas lié aux conditions de culture, à l'origine des souches isolées, à l'âge de la culture ou à la présence des antigènes des fimbriae.
