Which pathogen is associated with outbreaks of joint infections due to contamination from multi-dose locations?

Serratia marcescens is recognized for its association with outbreaks of joint infections, particularly following contamination in multi-dose medication vials. This bacterium can survive in a variety of environments and is known to thrive in healthcare settings, particularly where sterile techniques may be compromised. Its ability to form biofilms and resist some disinfectants enhances its potential for causing infection in vulnerable populations, such as those in nursing homes or other long-term care facilities.

The risk posed by Serratia marcescens in a healthcare context is largely due to its transmission through contaminated syringes or vials, leading to serious infections when introduced into the body, particularly in joint spaces. Maintaining proper infection control practices, such as strict adherence to aseptic techniques during medication administration and regular disinfection of multi-dose vials, is crucial in preventing such outbreaks.

This understanding underscores the importance of stringent infection prevention protocols in healthcare settings to minimize the risk of contamination and consequent infections.
