Sep 1, 2020 · Bacterial pneumonia, characterized by inflammation in lung parenchyma and alveolar spaces, is caused by various bacteria, each triggering an intricate interplay with the host immune response.

Jul 31, 2023 · The most common cause of typical bacterial pneumonia worldwide is Pneumococcus. The polysaccharide capsule of Streptococcus pneumoniae inhibits the complement binding to the cell surface and hence, inhibits phagocytosis.

Jul 31, 2023 · Bacterial pneumonia is associated with purulent or rarely blood-tinged sputum. Viral pneumonia is associated with watery or occasionally mucopurulent sputum production. There may be an associated pleuritic chest pain with the concomitant involvement of the pleura.

Bacterial pneumonia. Bacteria, including gram-negative and gram-positive species, are frequent causes of CAP and HAP. The most frequent cause of bacterial pneumonia is infection with the gram-positive S. pneumoniae.

Streptococcus pneumoniae (J13) is the most common bacterial cause of pneumonia in all age groups except newborn infants. Streptococcus pneumoniae is a Gram-positive bacterium that often lives in the throat of people who do not have pneumonia. Other important Gram-positive causes of pneumonia are Staphylococcus aureus (J15.2) and Bacillus anthracis.

Jul 3, 2024 · Bacterial pneumonia (see the image below) is caused by a pathogenic infection of the lungs and may present as a primary disease process or as the final, fatal disorder primarily in an...

Apr 8, 2021 · The pathogenesis of pneumonia has been suggested to include a change in the lung microbiota, from a physiological, homeostatic state to dysbiosis, in association with a low microbial diversity...

Other common pathogens include atypical organisms (Chlamydophila pneumoniae, Legionella pneumophila, Mycoplasma pneumoniae), Hemophilus influenzae, enteric Gram-negatives (especially in those with chronic illness and aspiration risk factors), and Staphylococcus aureus.

Feb 26, 2024 · Bacterial pneumonia, characterized by inflammation in lung parenchyma and alveolar spaces, is caused by various bacteria, each triggering an intricate interplay with the host immune response.

Mar 2, 2022 · Table 1 gives an overview of the most common bacterial pathogens found in pneumonia. Aside from bacterial infections, Community-Acquired Pneumonia is often found to be caused by viral pathogens including COVID-19, Cytomegalovirus, Herpes Simplex Virus, Adenovirus and Respiratory Syncytial Virus.
