Serratia marcescens is a Gram-negative, rod-shaped bacterium that belongs to the genus Serratia.
Serratia marcescens can cause the following infections and diseases, among others:
Urinary tract infections
Endocarditis (inflammation of the heart’s inner lining)
Serratia marcescens is found in soil, water, plants, and animals. It can also form biofilms.
Relevance of pathogen in transmission in endoscopy
Ear, nose, and throat: Not relevant
Relevance for endoscope processing
High concern organism
Infections can occur through the environment, direct human to human contact, or through touching contaminated objects.
Resistance to antibiotics
Serratia marcescens is an ESBL-producing strain (ESBL = extended-spectrum beta-lactamase) and exhibits resistance to several antibiotics. The bacterium is resistant to penicillins, carbapenems, and macrolides.
