Notes:
The comparative accuracy of the serological assays AQUARAPID-Va, AQUAEIA-Va (BIONOR AS), and dot-blot for a rapid diagnosis of vibriosis in fish was evaluated. Twenty-one Vibrio anguillarum strains, representative of pathogenic and environmental serotypes, and 13 strains of other fish pathogenic bacteria were used to assess the sensitivity and specificity of the detection methods. The serological assays tested detected all the strains of V. anguillarum serotypes O1 and O2. The dot-blot assay was the most specific and sensitive method, detecting almost all isolates from serotypes O1, O2 and O3, with an average sensitivity of 1 × 106 bacteria g−1 of fish tissue. The AQUARAPID-Va and the AQUAEIA-Va systems were able to detect 5 × 106 and 5 × 107 bacteria g−1 of fish tissue, respectively. The simplicity, effectiveness and speed of the AQUARAPID-Va system confirmed this method as the most suitable serological test for the detection of V. anguillarum in field analysis and small-scale laboratory studies.
