Abstract

A simple, high-throughput, low-cost polymerase chain reaction-enzyme linked immunosorbent assay (PCR-ELISA) protocol that detects the presence of 4 fg of DNA from four bacterial fish pathogens Yersinia ruckeri, Tenacibaculum maritimum (formerly Flexibacter maritimus), Lactococcus garvieae and Aeromonas salmonicida was developed. DNA amplification was undertaken in a biphasic system with free and bound PCR that are achieved in the one NucleoLink tube. Solid-phase amplicons were detected using biotin labelled hybridization probes and visualised colourimetrically with streptavidin-alkaline phosphatase and p-nitrophenylphosphate as substrate. PCR and hybridization took less than 8 h to perform with maximum signal output for femtogram amounts of template DNA achieved within 24 h. Implementation and optimization of the protocol is discussed. © 2002 Elsevier Science B.V. All rights reserved.
