Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
The different serotyping systems, based on thermostable O antigens, reported for Vibrio anguillarum and V. ordalii were compared by quantitative agglutination, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and subsequent silver staining or Western blotting (immunoblotting) of purified lipopolysaccharide (LPS), using polyclonal rabbit antisera. The results demonstrate that 16 different serotypes within V. anguillarum (designated 01 to 016) can be distinguished. Each of these serotypes is characterized by a distinct polysaccharide banding pattern, as revealed by silver-stained gels of purified LPS. The comparative analysis allowed a complete alignment of the different stereotypes for the first three serovars: 01, 02 and 03. Moreover, immunoblotting showed that strains belonging to each of these serotypes had the same LPS banding pattern independent of the origin of the strain. Stereotype 02 contains different subtypes, 02a and 02b. While no differences were apparent between these subgroups in silver-stained gels, they could be separated by quantitative agglutination (titer determination) or immunoblotting. V. ordalii, the former biotype II of V. anguillarum, strongly reacts with anti-V. anguillarum 02a antiserum. Strains of the two species can be separated in the basis of different LPS profiles in the high-molecular-weight region of silver-stained gels of purified LPS. The silver-stained LPS profiles of the different serotypes of V. anguillarum that have been established are provided for further comparison in the future. |
