Abstract

Ralstonia pickettii, an oligotrophic betaproteobacteria is found in rivers, soils, lakes, and in biofilms in plastic water pipes. The objective of this case report was to describe a case of R. pickettii causing ventilator-associated pneumonia in an intensive care unit (ICU) setting, focusing on risk factors, antibiotic sensitivity patterns, clinical characteristics, management, and outcomes. A 45-year-old male patient presented to the Emergency Department with a complaint of neurotrauma after a road traffic accident. Decompressive craniectomy was done and the patient was shifted to ICU for postoperative care and mechanical ventilation, later patient was tracheostomized in view of prolonged mechanical ventilation, poor GCS, and for better tracheal toilet. Later patient developed pneumonia, and antimicrobial susceptibility testing showed the isolate R. pickettii, sensitive to levofloxacin and piperacillin/tazobactam. After five days of treatment, the patient was weaned from the ventilator.
