What type of infections are commonly associated with Serratia marcescens?

Serratia marcescens is often recognized for its role as an opportunistic pathogen, particularly in healthcare settings. Bloodstream infections are among the most serious infections caused by this bacterium. It is capable of entering the bloodstream and causing complications, especially in individuals with weakened immune systems, such as those residing in nursing homes. These infections can result from various sources, including contaminated medical devices or breaches in infection control practices.

While Serratia marcescens can also be associated with respiratory, gastrointestinal, and skin infections, bloodstream infections are particularly significant due to their severity and the potential for high morbidity and mortality. This highlights the importance of effective infection control measures to prevent such infections in vulnerable populations.
