Clinical Significance

Histoplasmosis, caused by infection by H. capsulatum, is usually asymptomatic or mild. Some patients develop chronic pulmonary histoplasmosis or acute disseminated histoplasmosis that is often life-threatening. Immunodiffusion testing detects antibodies in approximately 70% of patients with histoplasmosis, and complement fixation testing detects antibodies in approximately 90% of patients.
