What Strain of Pneumonia Can Cause Alveolar Consolidation?

Alveolar consolidation can be caused by pneumonia in the lobes or air passages of the lungs and by pneumonia caused by pathogens, according to HealthHype.com. The infectious organisms are usually bacteria, including Streptococcus pneumoniae, Escherichia coli, Staphylococcus aureus or Klebsiella pneumoniae.

Consolidation in the lungs can affect one part of a lobe, the entirety of one lobe, or both lobes, says HealthHype.com. The symptoms depend on how extensive the consolidation is, but include difficulty breathing, and abnormal, noisy breathing. In some cases, the person may have a blue tinge to the skin due to lack of oxygen. This is called cyanosis, says MedlinePlus.
