MORPHOLOGICAL SIGNIFICANCE OF THE STRUCTURE OF CEREBRAL VESSELS IN RATS

Abstract

The problem of community-acquired pneumonias in children remains acute at present. Complicated forms, which include pleural empyema, abscess, necrotizing or destructive pneumonia, bronchopleural fistula and acute respiratory distress syndrome are not becoming less, despite the modern antibacterial therapy and availability of vaccination against pneumococcus. The main pathogens associated with lung destruction in children remain S. pneumoniae and S. aureus, often MRSA. Much less often the role of other pathogens in necrotizing pneumonias is reported: Streptococcus pyogenes, Haemophilus influenzae, Pseudomonas aeruginosa, Fusobacterium nucleatum, Legionella pneumophila, Klebsiella pneumoniae, anaerobes. However, not only pathogenic factors of the causative agent are important in the pathogenesis of the disease. Often viral prodrome, often associated with influenza A (H1N1) virus, precedes the development of complicated pneumonia.
