A medium for inducing conversion of Histoplasma capsulatum var. capsulatum into its yeast-like form [PDF]

Memorias do Instituto Oswaldo Cruz, 1992
Histoplasma capsulatum var. capsulatum is a dimorphic fungus that, under special conditions, converts from its more common mycelial form to a yeast-like form. Achieving this conversion, however, has been problematical for researchers.

Synthesis and antifungal activity in vitro of isoniazid derivatives against histoplasma capsulatum var. capsulatum. [PDF]

Antimicrob Agents Chemother, 2014
ABSTRACT Histoplasmosis is a severe infection that affects millions of patients worldwide and is endemic in the Americas. Amphotericin B (AMB) and itraconazole are highly effective for the treatment of severe and milder forms of the disease, but AMB is toxic, and the bioavailability of itraconazole is erratic.

A complementary tool for management of disseminated Histoplasma capsulatum var. capsulatum infections in AIDS patients [PDF]

International Journal of Medical Microbiology, 2014
In South America, disseminated histoplasmosis due to Histoplasma capsulatum var. capsulatum (H. capsulatum), is a severe and frequent opportunistic infection in AIDS patients. In areas outside the USA where specific-Histoplasma antigen detection is not available, the diagnosis is difficult. With the galactomannan antigen (GM) detection, a test commonly

An aberrant variant of Histoplasma capsulatum var. capsulatum [PDF]

Journal of Clinical Microbiology, 1997
We studied an aberrant culture of Histoplasma capsulatum var. capsulatum isolated from synovial fluid collected from the right elbow of a patient from Kansas. Colonies on Sabouraud glucose agar and other routine mycological media were glabrous to soft, moist, heaped, deeply folded or convoluted, and orange-brown with a white, irregular margin ...

Molecular Detection of Histoplasma capsulatum var. capsulatum in Human Clinical Samples [PDF]

Journal of Clinical Microbiology, 2003
ABSTRACT We developed a seminested PCR for the diagnosis of histoplasmosis that amplifies a portion of the Histoplasma capsulatum H antigen gene. This assay is highly sensitive and specific, being able to detect genomic material corresponding to less than 10 yeast cells without cross-reaction against other
