| Abstract: | ABSTRACT: Random sequencing of the genomic DNA of Photobacterium damselae subsp. piscicida was conducted. The sequences were assembled into 930 contigs. The total length of these contigs accounts for 37.5% of the genome of P. damselae subsp. piscicida. The contigs contain 2055 open reading frames (ORFs) that have homology with genes in the GenBank database. Furthermore, some of the ORFs have homology with reported virulence related genes, and are classified as encoding colonization factors, exotoxin, and lipopolysaccharide (LPS). Thirty-seven ORFs have homology with colonization factors. In those colonization factors, 27, three, and four ORFs have homology with polar flagellar-related genes, capsule-related genes, and others (accessory colonization factors, superoxide dismutase (Cu-Zn), MshA biogenesis protein, and heme receptor genes), respectively. Five ORFs have homology with exotoxin-related genes (2 hemolysin, phospholipase, hyaluronidase, lysophospholipase L2 genes). Further, six ORFs have homology with LPS-related genes. |
