Serratia
Sign in to saveSerratia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Yersiniaceae. They are typically 1–5 μm in length, do not produce spores, and can be found in water, soil, plants, and animals. Some members of this genus produce a characteristic red pigment, prodigiosin, and can be distinguished from other members of the order Enterobacterales by their unique production of three enzymes: DNase (nucA), lipase, and gelatinase (serralysin). Serratia was thought to be a harmless environmental bacteria until it was discovered that the most common species in the g

Bei Bakterien der Gattung Serratia handelt es sich um eine Gruppe gramnegativer, fakultativ anaerober Stäbchenbakterien aus der Familie der Enterobakterien (Enterobacteriaceae). Im Deutschen werden sie als Serratien bezeichnet. Eine bekannte Art aus der Gattung ist Serratia marcescens, deren Merkmal die rote Pigmentierung ist. Serratia-Arten kommen, wie auch andere Enterobakterien, im Darm vor, sie sind aber ebenso in anderen Lebensräumen ubiquitär verbreitet. Sie kommen im Wasser, im Boden, bei Tieren und auf Pflanzen vor. Sie können für manche Insekten pathogen sein, andererseits sind auch Fälle von Symbiosen bekannt. Viele Serratia-Arten sind für den Menschen apathogen oder nur selten als Krankheitserreger (etwa von Bakteriämien und Lungenentzündungen) nachgewiesen worden. Es wurde jedoch vereinzelt über nosokomiale Infektionen in Kinderabteilungen und Intensivstationen berichtet. Die Systematik innerhalb der Gattung Serratia hat sich seit Beginn des 20. Jahrhunderts mehrfach verändert. In der Vergangenheit wurden oftmals Bakterien mit einer roten oder rosa Färbung der Kolonien als Serratia-Art klassifiziert. Aktuell (Stand 2014) sind 15 verschiedene Arten bekannt.

Serratia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Yersiniaceae. They are typically 1–5 μm in length, do not produce spores, and can be found in water, soil, plants, and animals. Some members of this genus produce a characteristic red pigment, prodigiosin, and can be distinguished from other members of the order Enterobacterales by their unique production of three enzymes: DNase (nucA), lipase, and gelatinase (serralysin). Serratia was thought to be a harmless environmental bacteria until it was discovered that the most common species in the genus, S. marcescens, is an opportunistic pathogen of many animals, including humans. In humans, S. marcescens is mostly associated with nosocomial, or hospital-acquired, infections, but can also cause urinary tract infections, pneumonia, and endocarditis. S. marcescens is frequently found in showers, toilet bowls, and around wet tiles as a pinkish to red biofilm but only causes disease in immunocompromised individuals. Aside from S. marcescens, some rare strains of the Serratia species – S. plymuthica, S. liquefaciens, S. rubidaea, and S. odoriferae – have been shown to cause infection such as osteomyelitis and endocarditis.
== Habitat == Various strains of Serratia occupy an eclectic range of habitats: soil, water, plants, insects, and others.
