infectious disease

Bronchopneumonia is a subtype of pneumonia. It is the acute inflammation of the bronchi, accompanied by inflamed patches in the nearby lobules of the lungs.[1]

It is often contrasted with lobar pneumonia; but, in clinical practice, the types are difficult to apply, as the patterns usually overlap.[2] Bronchopneumonia (lobular) often leads to lobar pneumonia as the infection progresses. The same organism may cause one type of pneumonia in one patient, and another in a different patient.

Causes

Bronchopneumonia is usually a bacterial pneumonia rather than being caused by viral disease.[medical citation needed]

It is more commonly a hospital-acquired pneumonia than a community-acquired pneumonia, in contrast to lobar pneumonia.[4]

Bronchopneumonia is less likely than lobar pneumonia to be associated with Streptococcus pneumoniae.[5] Rather, the bronchopneumonia pattern has been associated mainly with the following: Staphylococcus aureus, Klebsiella, E. coli and Pseudomonas.[6]

Pathology

Histopathology of bronchopneumonia, showing neutrophils filling a bronchiole.

Bronchopneumonia may sometimes be diagnosed after death, during autopsy.

On

human lung, often bilateral. These lesions are 2–4 cm in diameter, grey-yellow, dry, often centered on a bronchiole
, poorly delimited, and with the tendency to confluence, especially in children.

Light microscopy typically shows neutrophils in bronchi, bronchioles and adjacent alveolar spaces.[2]

Treatment

Compared to pneumonia in general, the association between the bronchopneumonia pattern and hospital-acquired pneumonia warrants greater consideration of multiple drug resistance in the choice of antibiotics.
