OBJECTIVES The nosocomial infections by Aspergillus species are associated with constructions and increased dust loads in hospital indoors. Our main object was to find the environmental sources of Aspergillus species causing hospital acquired infections. MATERIALS AND METHODS The clinical and environmental samplings were performed during 18 months from spring 2010 to summer 2011 in Imam educa...

The study site located in the Mediterranean Sea was visited eight times in 2005 and 2006 to collect samples from the epipelagic (5 m), mesopelagic (200 m, 600 m), and bathypelagic (1,000 m, 2,000 m) zones. Randomly amplified polymorphic DNA PCR (RAPD-PCR) analysis was used to obtain fingerprints from microbial and viral size fractions using two different primers each. Depending on the primer us...

Helicobacter pylori isolates show greater genetic diversity than other bacterial species studied, but the basis for this phenomenon is unknown. Whether detectable genomic mutation appears within an H. pylori population during persistent colonization was investigated. Paired H. pylori populations obtained across 7- to 10-year intervals from 13 patients were characterized by use of methods includ...

From fruiting bodies of L. edodes strain L-54, single-spore isolates (SSIs) were collected. Two parental types of L-54 were regenerated via monokaryotization. By means of random-amplified polymorphic DNA (RAPD), DNA samples from L-54, its two parental types, and 32 SSIs were amplified with arbitrary primers. Dedikaryotization was demonstrated, and 91 RAPD-based molecular markers were generated....

Thirty-three strains of Cryptococcus neoformans were isolated from clinical specimens, including specimens from AIDS patients in Brazil, and were classified into two serotypes; we detected 31 and 2 strains of serotypes A and B, respectively. Random amplified polymorphic DNA (RAPD) fingerprint pattern analyses of these strains of serotypes A and B showed that the patterns were similar for strain...

dermatophytes are a group of keratinophilic fungi capable of invading keratinized tissues (skin, hair and nails). they cause dermatophytosis (commonly known as tinea or ring worm) in human and animals. in this report, dna similarities and genomic linkage of 40 dermatophytes strains was obtained from different universities, were studied by random amplified polymorphic dna (rapd–pcr) using 11 ran...

The aim of the study was to compare the discriminatory power of RAPD-PCR method using RSD10 primer and microsatellite (GACA)4 analysis for genotyping clinical isolates of C. glabrata. Isolates were received from patients of two Polish hospitals: Children's Memorial Health Institute in Warsaw (n=17) and Medical University of Gdansk (n=37). Species identification was confirmed by two phenotypic m...
