Serratia marcescens is a species of rod-shaped gram-negative bacteria in the family Enterobacteriaceae.. marcescens may also be found in environments such as dirt, supposedly sterile places, and the subgingival biofilm of teeth.
It is differentiated from other Gram-negative bacteria by its ability to perform casein hydrolysis, which allows it to produce extracellular metalloproteinases which are believed to function in cell-to-extracellular matrix interactions. S. marcescens also exhibits tryptophan and citrate degradation.t is commonly found in the respiratory and urinary tracts of hospitalized adults and in the gastrointestinal system of children. Serratia may be correctly pronounced Ser-ra-shia (common) or Ser-rah-tee-a.
