Microbial etiologies of ventilator-associated pneumonia (VAP) in intensive care unit of Beni-Suef University’s Hospital
Abstract Background Ventilator-associated pneumonia (VAP) is a major health problem for people intubated in intensive care units (ICUs), leading to increased mortality rates, hospital stay, and treatment costs. In the present study, the core pathogens causing VAP in Beni-Suef University's Hospi...
