Bacterial Pneumonia in Children – Epidemiological Study on Nine Years


Pneumonia can be defined as an inflammation of the pulmonary parenchyma, mainly affecting the alveolar space. Inflammation can be caused by bacteria and viruses, as well as by inhalation of chemical agents or due to thoracic trauma (1,2,6).
Most authors classify bacterial pneumonias depending on the pathogenic agent, this classification including species of Pneumococcus, Hamophillus Influenzae, Klebsiella, Staphylococcus, Legionella and other gram-negative microorganisms. Some germs, especially Staphylococcus may be disseminated in a haematogenous manner.
