In order to confirm the phylogenetic relationships of Histoplasma capsulatum, the partial sequences of large subunit (28S) ribosomal gene (D1/D2 region) of 49 isolates were studied. The similarity values of the 49 isolates were more than 99.0% across 617 base pairs, however, the 49 isolates were divided into 9 groups. These 9 groups were independent of 3 varieties, var. capsulatum, var. farcimi...
Infective endocarditis is an uncommon manifestation of infection with Histoplasma capsulatum. The diagnosis is frequently missed, and outcomes historically have been poor. We present 14 cases of Histoplasma endocarditis seen in the last decade at medical centers throughout the United States. All patients were men, and 10 of the 14 had an infected prosthetic aortic valve. One patient had an infe...
Infection with histoplasma capsulatum is endemic in many parts of the world. This organism is of generally low human virulence but can act as an opportunistic agent when host immune responses allow persistent parasitization of macrophages (acute pulmonary and disseminated histoplasmosis) or when abnormal pulmonary spaces due to emphysema allow colonization of these spaces and its consequences. ...
An inhibitor of ribonucleic acid polymerases has been obtained from the mycelial phase of Histoplasma capsulatum and partially characterized. The inhibitor, called histin, was purified 200-fold by heat treatment at 100 C and electrophoresis on polyacrylamide gels. Histin moved in electrophoresis as if negatively charged; it was insensitive to treatment with ribonuclease of deoxyribonuclease but...
Billiary tract involvement in the course of disseminated histoplasmosis has been rarely reported. Here we present a severely immunosuppressed HIV-infected patient who presented with symptomatic acalculous cholecystitis caused by Histoplasma capsulatum.
Cavitary lung lesions in histoplasmosis are usually associated with the chronic form of the disease. This report describes a ten-year-old boy with the clinical and serologic pattern of acute Histoplasma capsulatum infection who had multiple cavitary lesions.
The antifungal susceptibility profiles of the mycelial and yeast forms of 23 Histoplasma capsulatum strains from pulmonary and disseminated histoplasmosis patients in India are reported here. The MIC data of this dimorphic fungus had good agreement between both forms for azoles, amphotericin B, and caspofungin. Therefore, the use of mycelial inocula for H. capsulatum antifungal susceptibility t...
