Ventilator Associated Pneumonia (VAP) is defined as pneumonia that occurs 48 hours or more after endotracheal intubation or tracheostomy, caused by infectious agents not present or incubating at the time mechanical ventilation started. While critically ill patients experience a life-threatening illness, they commonly contract ventilator-associated pneumonia. This nosocomial infection increases morbidity and likely mortality as well as the cost of health care. This study aims to find out the bacterial profile of VAP in geriatric patients and the antibiotic susceptibility pattern of the isolated pathogen including detection of MRSA, ESBLs and MBLs. This study was conducted in the Department of Microbiology at ESIC MC and PGIMSR, Rajajinagar, Bengaluru from January 2017 to June 2018. A total of 38 isolates from 35 VAP patients were collected during the study. | Microbiological profile of ventilator associated pneumonia (VAP) in geriatric patients and their antibiotic susceptibility pattern with detection of MRSA, ESBLs and MBLs in intensive care unit of a tertiary care centre from south India
