Abstract
In nature, the fruit fly frequently encounters various pathogens that cause a decrease in host fitness. Here, we present the genome sequence of Serratia marcescens strain FY, which was isolated from the intestines of a Drosophila specimen. The complete genome sequence comprises one chromosome of 5,074,453 bp and two plasmids of 100,934 bp and 87,789 bp. A total of 4,891 coding sequences are predicted from this assembly.
