Pneumocystis colonization – http://id.who.int/icd/entity/1456478752

Colonization with Pneumocystis jirovecii without clinical pneumonia. P. jirovecii can be recovered or detected by polymerase chain reaction from the respiratory tracts of immune competent and immune suppressed individuals without any evidence of active infection or pneumonia. These patients do not manifest any clinical symptoms. Patients may have normal lung architecture. However, colonization is more commonly observed in patients with underlying structural lung disease including airways diseases such as COPD or interstitial lung diseases.
