Risk Factors and Clinical Outcomes of Stenotrophomonas maltophilia Infections: Scenario in a Tertiary Care Center from South India

Abstract

Stenotrophomonas maltophilia, a gram-negative non-fermenter has evolved from a colonizer to a significant pathogen over the last decade. It resides in various ecological niches both inside and outside the hospital settings. Infections due to S. maltophilia can be life-threatening, especially in immunocompromised patients. S. maltophilia is intrinsically resistant to most of the antibiotics, which limits treatment options. There are several risk factors involved. The present study was done to assess the risk factors and clinical outcomes associated with S. maltophilia blood stream infections and non-blood stream infections.
