Burn wounds are associated with an increased risk of nosocomial infection by Pseudomonas spp and led to increased mortality among these infected patients. The reservoir of such an infection could be contaminated disinfectant bottles, water supplies, unsterilized surgical equipments etc. We report an outbreak in a burn intensive care unit (ICU) of a tertiary care hospital with multidrug-resistant Pseudomonas aeruginosa only sensitive to fluroquinolones. We established an outbreak investigation team, performed an exploratory analysis and initiated an intervention. Cases were identified as any patient infected with the outbreak strain of Pseudomonas aeruginosa after 48 hours of admission in the burn ICU from November 2017 to February 2018. We performed microbiological examinations of the clinical samples and environmental samples. All the isolates was identified by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF VITEK®MS), and antimicrobial susceptibility testing for the isolates were done by VITEK®2 system. Outbreak strain isolated from 9 patients. During the source tracing the same multidrug resistant strain was found on the nozzle and pipe of the unsterilized saline sprinkler used for burn wound dressing since 5 months. After stoppage of this sprinkler in the ICU and implementing strict infection control practices, no more outbreak strain isolated further.
