Abstract

ABSTRACTWe present the genome sequence of Vibrio jasicida 20LP, a bacterial strain retrieved from larvae of gilthead seabream (Sparus aurata), a highly valuable, model fish species in land-based aquaculture. Annotation of the V. jasicida 20LP genome reveals multiple genomic features potentially underpinning opportunistic associations with diverse marine animals.

Highlights

  • Vibrio jasicida is a relatively recently described bacterial species that belongs to the Vibrio harveyi clade and can be found in association with diverse marine animals, such as lobsters, gastropods, and fish [1]

  • Sixty-two coding sequences (CDSs) were classified into the virulence, disease, and defense subsystem within Rapid Annotation using Subsystem Technology (RAST), of which 47 CDSs were involved in resistance to antibiotics, toxic compounds, and bacteriocins; these include genes encoding proteins for copper homeostasis (13 CDSs), bile hydrolysis (2 CDSs), and resistance to cobalt-zinc-cadmium (5 CDSs), fluoroquinolones (2 CDSs), colicin E2 (2 CDSs), copper (13 CDSs), and chromium (1 CDS), as well as multidrug resistance efflux pumps (9 CDSs)

  • Regarding invasion and intracellular resistance, 14 CDSs resembling the Mycobacterium virulence operon were found, with 6 and 3 CDSs involved in small subunit (SSU) and large subunit (LSU) ribosomal protein synthesis, respectively, 2 CDSs involved in DNA transcription, and 3 CDSs involved in quinolinate biosynthesis

Summary

Introduction

Vibrio jasicida is a relatively recently described bacterial species that belongs to the Vibrio harveyi clade and can be found in association with diverse marine animals, such as lobsters, gastropods, and fish [1]. Genome annotation was carried out with Rapid Annotation using Subsystem Technology (RAST) v2.0, using the RASTtk protocol [8], and the NCBI Prokaryotic Genome Annotation Sanches-Fernandes et al TABLE 1 General features of the Vibrio jasicida 20LP genome
