show Abstracthide AbstractThe aim of the present study was to classify and determine phylogenetic relationships of Shewanella spp. collected from fish. The complete genomes of 94 strains of Shewanella spp. from different fish species were sequenced using Illumina platform (MiSeq). Whole genome analysis showed that tested Shewanella spp. strains were clustered into 6 groups similar to reference strains of S. xiamenensis, S. oneidensis, S. glacialipiscicola, S. hafniensis, S. baltica, and S. oncorhynchi.
