Serratia is a genus of Gram-negative, facultatively anaerobic, endosporeforming,rod-shaped bacteria of the Enterobacteriaceae family. The most common and pathogenic of the species in the genus, S. marcescens, is normally the only pathogen and usually causes nosocomial infections. However, rare strains of S. plymuthica, S. liquefaciens, S. rubidaea, and S. odoriferae have caused diseases through infection.S. marcescens is typically found in showers, toilet bowls, and around wetted tiles. Members of this genus produce characteristic red pigment, prodigiosin, and can be distinguished from other members of the Enterobacteriaceae family by their unique production of three enzymes: DNase, lipase, and gelatinase. A pan-genome analysis of the genus Serratia revealed that it does not depict exceptional genetic conservation or diversity as compared to other bacterial genera.
