Etiology and Pathogenesis of Pneumonia in Children

摘要

This review focuses on the etiology and pathogenesis of pneumonia in children. Over the last decade, there has been a significant expansion of the acute pneumonia pathogen spectrum. Apart from bacterial microflora, pneumonic viruses, mycoplasms, chlamydia, rickettsia, protozoa and fungi are becoming increasingly important in the development of pneumonia in children. The mechanism of pneumonia development has not been sufficiently studied. Most often, the pathogen from the nasopharynx penetrates and spreads aerobronchogenic way with the subsequent occurrence of the inflammatory process in acinuses. The abundance of lymphatic vessels in the lung tissue is important in pathogenesis, especially in young children.
