Abstract

Photobacterium damselae subsp. piscicida (PDP) is the causative agent of fish pasteurellosis, a bacterial disease causing important losses in marine aquaculture. Vaccines against the pathogen can be a way to control the infection and avoid antibiotic treatments. However, a satisfactory protective vaccine against fish pasteurellosis is not commercially available. In this study, a biotechnogical approach based on reverse vaccinology has been used to identify potential vaccine candidates for the development of a recombinant subunit vaccine. Genome sequencing of clones from a genomic cosmid library of PDP and in silico selection of the surface exposed proteins were the initial steps in vaccine candidate identification. From 370 open reading frames (ORF) eight potential antigens were selected, expressed as recombinant proteins and purified. These vaccine candidates were used to generate specific polyclonal antibodies in mice. Each antibody was then screened in vitro by inhibition adherence assay of live PDP on chinook salmon embryo cells (CHSE-214). A lipoprotein, found to be involved in the adherence of the bacterium to epithelial cells and annotated as PDP_0080, was then selected. The recombinant protein was further investigated in fish vaccination and challenge experiments to assess its ability to protect sea bass, Dicentrarchus labrax, against PDP infection. Immunisation with PDP_0080 recombinant protein elicited high specific antibody titres. Furthermore, the survival rate of fish immunized with the 25 ?g dose of protein was significantly higher compared to the control group. The results of the study suggest that the PDP_0080 protein could be a promising candidate for the design of a recombinant vaccine against pasteurellosis. (literal)
