In this study, a new Escherichia phage, GaoY1-9D, was isolated from farm sewage samples and sequenced. Its genome length is 50,368 bp, and its G + C content is 46.46%. The genome of phage GaoY1-9D is a double-stranded circular DNA that has 127-bp terminal repeats at both ends and does not contain any tRNA genes. Based on the results of genome sequence comparisons, Escherichia phage GaoY1-9D represents a new species in the family Drexlerviridae.
