The use of restriction endonuclease analysis and Southern hybridization with our new CkF1,2 DNA probe, cold labeled with peroxidase, for the typing of Candida krusei isolates has been investigated. Fifty-five clinical samples isolated from forty-five patients hospitalized in eight centers, one environmental strain, and two reference strains were evaluated. Patterns were analyzed by a computer-assisted method and compared by numerical analysis. Clearer and less ambiguous patterns were obtained by restriction with endonuclease HinfI. It generated 9 to 14 (average, 11) well-separated fragments in the range of 6.5 to 2.0 kb. Both their numbers and sizes varied greatly among the strains studied. The CkF1,2 probe hybridized with one to seven fragments of HinfI patterns. A total of 48 distinct types were distinguished among the 58 strains studied. HinfI and CkF1,2 patterns showed similarities of less than 83 and 75% for unrelated strains and more than 91 and 100% for related strains, respectively. The methods showed 100% typeability, 98% reproducibility, and a discriminatory power of 1. C. krusei isolates from each patient were distinct, whether from one hospital or from different hospitals. Multiple isolates from the same patient were identical, both over time and at different anatomic sites. An endogenous origin is suggested for the colonizing and infecting isolates among the 45 patients. The CkF1,2 probe enhanced discrimination of the strains and provided a definitive comparison for strain identity. Genetic linkages between isolates were assessed at the subspecies level, and 12 clusters were delineated. A typing scheme is proposed for epidemiological studies of C. krusei.

D002175 Candida A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; VULVOVAGINAL CANDIDIASIS; and CANDIDIASIS, ORAL (THRUSH).

D004262 DNA Restriction Enzymes Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.

D015139 Blotting, Southern A method (first developed by E.M. Southern) for detection of DNA that has been electrophoretically separated and immobilized by blotting on nitrocellulose or other type of paper or nylon membrane followed by hybridization with labeled NUCLEIC ACID PROBES.

D015342 DNA Probes Species- or subspecies-specific DNA (including COMPLEMENTARY DNA; conserved genes, whole chromosomes, or whole genomes) used in hybridization studies in order to identify microorganisms, to measure DNA-DNA homologies, to group subspecies, etc. The DNA probe hybridizes with a specific mRNA, if present. Conventional techniques used for testing for the hybridization product include dot blot assays, Southern blot assays, and DNA:RNA hybrid-specific antibody tests. Conventional labels for the DNA probe include the radioisotope labels 32P and 125I and the chemical label biotin. The use of DNA probes provides a specific, sensitive, rapid, and inexpensive replacement for cell culture techniques for diagnosing infections.
