Serratia marcescens is a widely distributed bacterium found in soil, water, and moist environments, including bathrooms and hospitals. It thrives in both natural and human-made settings, playing a role in organic matter decomposition while also being an opportunistic pathogen in healthcare settings.
Serratia marcescens is a Gram-negative, rod-shaped facultative anaerobe known for producing a distinct red pigment called prodigiosin. This pigment has antimicrobial and anticancer properties. The bacterium is motile due to flagella and can survive in diverse conditions, including hospital environments, where it can cause infections.
