What type of infections is Stenotrophomonas maltophilia primarily associated with?

Stenotrophomonas maltophilia is primarily associated with nosocomial infections, which are infections acquired in a healthcare setting, such as hospitals. This organism is an opportunistic pathogen, meaning it typically affects individuals who are immunocompromised, have underlying health conditions, or have invasive medical devices.

In the context of nosocomial infections, Stenotrophomonas maltophilia can cause a variety of clinical infections, especially in patients with weakened immune systems, such as those in intensive care units. It is known for its resistance to many commonly used antibiotics, which complicates treatment options and increases the risk of persistent infections in these vulnerable populations.

While Stenotrophomonas maltophilia can also be involved in other types of infections, such as respiratory tract infections, particularly in patients with cystic fibrosis, and occasionally in skin and urinary tract infections, its most significant association remains with nosocomial infections. This highlights the importance of infection control measures and vigilant antimicrobial stewardship in healthcare settings to manage and prevent such infections.
