Ventilator-associated pneumonia (VAP) is one of the common serious infectious diseases encountered in the intensive care unit (ICU), which highly affects the healthcare cost and patient prognosis.~All-cause of mortality associated with VAP has been reported to range from 20% to 50%.~The etiology of VAP and their antimicrobial susceptibility pattern varies with different patient populations and types of ICUs.~VAP may be caused by a wide spectrum of bacterial pathogens, which may be polymicrobial and are rarely due to viral or fungal pathogens in immune-competent hosts.~Common etiologic agents are Gram-negative bacilli such as Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, and Acinetobacter spp. and Staphylococcus aureus among Gram-positive cocci.~Due to the increased incidence of MDR organisms in Intensive Care Units (ICUs), early and correct diagnosis of VAP is mandatory for optimal antibiotic therapy. The frequency of specific MDR pathogens causing VAP varies in hospitals, patient populations. Also varies according underlying disease.~this study will be conducted in respiratory intensive care unit, chest disease and tuberculosis department at Assiut university hospitals.
