Apoptosis modulates protective immunity to the pathogenic fungus Histoplasma capsulatum.
Pathogen-induced apoptosis of lymphocytes is associated with increased susceptibility to infection. In this study, we determined whether apoptosis influenced host resistance to the fungus Histoplasma capsulatum. The level of apoptotic leukocytes progressively increased in the lungs of naive and immune mice during the course of H. capsulatum infection. T cells constituted the dominant apoptotic ...
متن کاملPhylogenetic relationships of varieties and geographical groups of the human pathogenic fungus Histoplasma capsulatum Darling.
The phylogeny of 46 geographically diverse Histoplasma capsulatum isolates representing the three varieties capsulatum, duboisii, and farciminosum was evaluated using partial DNA sequences of four protein coding genes. Parsimony and distance analysis of the separate genes were generally congruent and analysis of the combined data identified six clades: (i) class 1 North American H. capsulatum v...
متن کاملGenome size, complexity, and ploidy of the pathogenic fungus Histoplasma capsulatum.
The genome size, complexity, and ploidy of the dimorphic pathogenic fungus Histoplasma capsulatum was determined by using DNA renaturation kinetics, genomic reconstruction, and flow cytometry. Nuclear DNA was isolated from two strains, G186AS and Downs, and analyzed by renaturation kinetics and genomic reconstruction with three putative single-copy genes (calmodulin, alpha-tubulin, and beta-tub...
متن کاملCloning and analysis of an actin-encoding cDNA from the dimorphic pathogenic fungus Histoplasma capsulatum.
We have cloned an actin-encoding cDNA from the dimorphic fungus Histoplasma capsulatum, an important pathogen of humans. The predicted amino acid sequence as well as the general codon pattern of Histoplasma actin revealed the highest degree of similarity to the actin of the filamentous ascomycete Aspergillus nidulans. Southern blot analysis determined that actin was encoded by a single copy in ...
متن کاملElectrotransformation and Expression of Bacterial Genes Encoding Hygromycin Phosphotransferase and b-Galactosidase in the Pathogenic Fungus Histoplasma capsulatum
We developed an efficient electrotransformation system for the pathogenic fungus Histoplasma capsulatum and used it to examine the effects of features of the transforming DNA on transformation efficiency and fate of the transforming DNA and to demonstrate fungal expression of two recombinant Escherichia coli genes, hph and lacZ. Linearized DNA and plasmids containing Histoplasma telomeric seque...
