Abstract
In this study, a novel Escherichia phage GaoY1-9D, was isolated from farm sewage samples. Its genome length is 50,368 bp and the G + C genomic content is 46.46%. The genome of phage GaoY1-9D is a double-stranded circular DNA, and contain 127 bp terminal repeats at both ends of the genomic sequence. No tRNA genes have been found in its genome. Based on the results of comparative genomics analysis, Escherichia phage GaoY1-9D is confirmed as a member of a new species, which belongs to the Drexlerviridae.
