Detection of Histoplasma capsulatum antigen in Panamanian patients with disseminated histoplasmosis and AIDS.
Histoplasmosis is a common endemic mycosis in the Americas, often causing severe disease in patients with AIDS. Antigen detection has become an important method for rapid diagnosis of histoplasmosis in the United States but not in Central or South America. Isolates from patients in the United States are predominantly found to be class 2 isolates when typed using the nuclear gene YPS3, while isolates from Latin America are predominantly typed as class 5 or class 6. ⋯ S. cases. Two clinical isolates from Panama were typed using YPS3 and were found to be restriction fragment length polymorphism class 6. We conclude that the MVista Histoplasma antigen EIA is a sensitive method for diagnosis of histoplasmosis in Panama.
