Hospital-acquired pneumonia (HP) accounts for 14 to 20% of the total structure of nosocomial infections, and ranks first in terms of mortality. The etiology of HP varies depending on the profile of the department and the microecological features of a particular hospital. The causative agents of HP are: P. aeruginosa, Enterobacter, E. coli, K. pneumoniae, Proteus spp., Serratia marcescens, H. influenzae, S. aureus, S. pneumoniae. In severe cases, highly resistant Gr (-) microorganisms (P. aeruginosa, Acinetobacter), methicillin-resistant S. aureus (MRSA), Candida spp., Aspergillus fumigatus, Pneumocysta carinii can be isolated. Legionella is responsible for less than 8% of HP cases. There are two variants of lung infection: the first is the endogenous route of infection (autoinfection); the second is an exogenous route of infection (from other patients or medical personnel), contaminated air, food, water, objects that come into contact with the patient's respiratory tract (bronchoscopes, catheters for sanitation of the tracheobronchial tree, etc.).
