DNA probe for the identification of Histoplasma capsulatum.

چکیده
A 1.85-kilobase HindIII nuclear DNA probe from Histoplasma capsulatum G217B detected polymorphic restriction fragments within whole-cell DNA from different clinical isolates of H. capsulatum, consistent with the previous system of classification. The probe failed to hybridize to DNA from Blastomyces dermatitidis, Candida spp., Saccharomyces cerevisiae, Sepedonium chrysospermum, and Chrysosporium keratinophilum under low-stringency conditions and therefore may have value as a diagnostic reagent to identify H. capsulatum.

A chemiluminescent DNA probe (Accuprobe) assay developed by Gen Probe, Inc., for the rapid identification of Histoplasma capsulatum was evaluated and compared with the exoantigen test by using 162 coded cultures including Histoplasma capsulatum var. capsulatum, Histoplasma capsulatum var. duboisii, Histoplasma capsulatum var. farciminosum, Blastomyces dermatitidis, Coccidioides immitis, Paracoc...
متن کاملEvaluation of Gen-Probe's Histoplasma capsulatum and Cryptococcus neoformans AccuProbes.
Gen-Probe's DNA probes were evaluated for use in the identification of clinical isolates of Histoplasma capsulatum var. capsulatum and Cryptococcus neoformans. Ninety-five mould-phase fungi were probed, including 41 isolates of H. capsulatum var. capsulatum. Similarly, 98 yeasts, including 42 C. neoformans isolates, were examined by using the C. neoformans DNA probe. In the study, both probes d...
متن کاملRapid identification of dimorphic and yeast-like fungal pathogens using specific DNA probes.
Specific oligonucleotide probes were developed to identify medically important fungi that display yeast-like morphology in vivo. Universal fungal primers ITS1 and ITS4, directed to the conserved regions of ribosomal DNA, were used to amplify DNA from Histoplasma capsulatum, Blastomyces dermatitidis, Coccidioides immitis, Paracoccidioides brasiliensis, Penicillium marneffei, Sporothrix schenckii...

Background: Histoplasma capsulatum var. duboisii is a rare fungus, endemic in southern Africa of the Sahara and Madagascar. Objective: To describe the confirmed cases of histoplasmosis. Methods: This retrospective study was conducted at the division of neurosurgery of Brazzaville academic hospital in the Republic of Congo. Clinical records of all confirmed cases who were admitted between Jan...
متن کاملGenetic analysis of Histoplasma capsulatum strains isolated from clinical specimens in thailand by a PCR-based random amplified polymorphic DNA method.
Thirteen strains of Histoplasma capsulatum were isolated from clinical specimens, including those from AIDS patients, in Thailand. Random amplified polymorphic DNA (RAPD) analysis with three different PCR primers showed that the DNA fingerprint patterns of the Thai isolates were very similar to each other and homogeneous, with only one exceptional strain, although the patterns were clearly diff...
