Abstract:
Stenotrophomonas maltophiliais an emerging cause of nosocomial infections. We report an outbreak of XDR-Stenotrophomonas maltophilia infection from burn unit of a tertiary care hospital in July 2016. The strain isolated was resistant to all antimicrobials tested but colistin. Outbreak investigation was carried out which subsided after timely intervention. Patients were treated adequately by Colistin.
Insights
An outbreak of extensively drug-resistant Stenotrophomonas maltophilia occurred in a hospital burn unit. Timely intervention and colistin treatment effectively controlled the infection, highlighting colistin
Area of Science:
- Infectious Diseases
- Microbiology
- Hospital Epidemiology
Background:
- Stenotrophomonas maltophilia is an increasing cause of healthcare-associated infections.
- The emergence of extensively drug-resistant (XDR) strains poses significant treatment challenges.
Observation:
- An outbreak of XDR Stenotrophomonas maltophilia infection was identified in a tertiary care hospital's burn unit in July 2016.
- The isolated strain demonstrated resistance to all tested antimicrobials except colistin.
Findings:
- A comprehensive outbreak investigation was conducted.
- The outbreak was successfully controlled following prompt and appropriate interventions.
- All affected patients received adequate treatment with colistin.
Implications:
- Colistin remains a crucial therapeutic option for XDR Stenotrophomonas maltophilia infections.
- Effective infection control and surveillance are vital for managing nosocomial outbreaks.
- This case underscores the importance of antimicrobial stewardship in combating resistant pathogens.
