PURPOSE Fungal ocular infections cause significant ocular morbidity, particularly when diagnosis and treatment are delayed. Accurate morphologic identification of Fusarium spp. beyond the genus is time-consuming and insensitive. It was the purpose of this study to examine the usefulness of the nuclear ribosomal RNA (rRNA) internal transcribed spacer regions (ITS1 and -2) to detect and different...

ABSTRACT Fusarium oxysporum f. sp. lactucae, causal agent of Fusarium wilt of lettuce, is a serious pathogen recently reported in Arizona. Sequence analysis of the mitochondrial small subunit (mtSSU), translation elongation factor 1-alpha (EF-1alpha) gene, and the nuclear ribosomal DNA intergenic spacer (IGS) region was conducted to resolve relationships among f. sp. lactucae isolates, F. oxysp...

Isolates of Fusarium were discovered in peat soil samples collected from peat swamp forest, waterlogged peat soil, and peat soil from oil palm plantations. Morphological characteristics were used to tentatively identify the isolates, and species confirmation was based on the sequence of translation elongation factor-1α (TEF-1α) and phylogenetic analysis. Based on the closest match of Basic Loca...

Fusarium oxysporum strain BM-201 was treated with ultraviolet (UV) radiation to obtain a high pectinase-producing strain. Mutant UV-10-41 was obtained and then treated by diethyl sulfate. Next, the mutant UV-diethyl sulfate-43 derived from UV-10-41 was selected as high pectinase-producing strain. Mutant UV-diethyl sulfate-43 was incubated on slant for 10 generations, demonstrating that the pect...

this study was carried out to identify fusarium species associated with sugar beet root rot and yellows. pathogenicity of fusarium oxysporum, the causal agent of fusariumyellows of sugar beet was also investigated. samples of infected roots were collected from fields in major sugar beet producing areas in khorasan province during 1999-2000. infected roots were washed, surface sterilised and pla...

ABSTRACT An epidemic of vascular wilt caused by Fusarium oxysporum f. sp. erythroxyli is currently occurring on Erythroxylum coca var. coca in the coca-growing regions of the Huallaga Valley in Peru. Random amplified polymorphic DNA (RAPD) analysis of isolates of the pathogen was undertaken to elucidate its genetic complexity, as well as to identify a specific DNA fingerprint for the pathogen. ...

This paper presents for the first time the isolation of Fusarium oxysporum from the toenails of a man from Tehran. The fungus was demonstrated in KOH mounts and was isolated repeatedly from his nail scrapings over a 2 month period. Published reviews on onychomycosis in Iran have not revealed any cases of white superficial onychomycosis due to Fusarium oxysporum to date

BACKGROUND To characterize Fusarium isolates from recent cases of fungal keratitis in contact lens wearers, and to investigate fungal association with MoistureLoc solution. METHODS We studied six fungal isolates from recent cases of keratitis in New York State. The isolates were characterized by nucleotide sequencing and phylogenetic analyses of multiple genes, and then typed using minisatell...

The MICs and minimum fungicidal concentrations of amphotericin B, natamycin, miconazole, itraconazole, and flucytosine against 17 isolates of Fusarium solani, 14 isolates of Fusarium moniliforme, 10 isolates of Fusarium oxysporum, and 3 isolates of Fusarium semitectum were determined by a broth microdilution method. Amphotericin B and natamycin were the most active agents tested and failed to s...
