Which pathogens may be associated with infections due to water exposure in healthcare facilities?

Serratia is recognized as a pathogen that can be associated with infections stemming from water exposure in healthcare settings. This genus of bacteria, particularly Serratia marcescens, can thrive in moist environments, such as those found in sinks, showers, and medical equipment that comes into contact with water. It is known to cause various infections, including respiratory infections and wound infections, particularly in immunocompromised patients or those with prior healthcare interventions.

Water systems in healthcare facilities that are not properly maintained can become reservoirs for Serratia, allowing it to proliferate and pose a risk to patients, especially when invasive procedures are performed. Infection prevention strategies often focus on controlling water quality, ensuring proper drainage, and regular maintenance to mitigate the risk of Serratia and other waterborne pathogens.

The other pathogens listed may be responsible for various types of infections in healthcare settings, but they do not typically have the same direct association with water exposure. For example, Clostridium difficile is primarily linked to antibiotic use and gut flora disruption rather than water sources. Each pathogen has its unique environmental preferences and mechanisms for infection, further highlighting the importance of targeted infection control measures based on understanding these associations.
