The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional ITS rDNA primary barcode. Amplification efficiencies 14 (partially) targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) outcomes almost twenty thousand (19 577) polymerase chain reactions evaluated. We several well-known that amplify: i) sections nuclear ribosomal RNA large...
Pathology to vertebrate hosts has emerged repeatedly in the order Ophiostomatales. Occasional infections have been observed Sporothrix mexicana at a low level of virulence, while main pathogenic species cluster derived clade around S. schenckii s.str. In this paper, phylogeny and epidemiology members were investigated for 99 clinical 36 environmental strains using four genetic loci, viz. rDNA ITS partial CAL, TEF1, TEF3; data are compared with amplified fragment length polymorphism (AFLP)...
Ochroconis is a dematiaceous fungus able to infect immunocompetent people. Recently, the taxonomy of genus has been reevaluated, and most relevant species, gallopava, was transferred new Verruconis. Due important clinical implications these fungi based on recent classification, it interest know spectra Verruconis species in samples received reference laboratory United States. A set 51 isolates identified morphologically molecularly sequence analyses nuclear ribosomal RNA (nrRNA), actin,...
To describe typical clinical and laboratory characteristics of severe fungal keratitis caused by Pythium insidiosum during the rainy season in Northeast Thailand to report efficacy P. vaccine treatment keratitis.A series hospital-based consecutive cases were diagnosed treated at Srinagarind Hospital (Khon Kaen University, Khon Kaen, Thailand). The presentations, diagnostic tests, management are described.Severe was 5 eyes 4 patients between May 2009 July 2009. All had a history after being...
Three human isolates of Pythium insidiosum De Cock 1987, the aetiologic agent pythiosis, were induced for zoosporogenesis. The grown on Sabouraud glucose agar 2 days before being inoculated into boiled spikelets Axonopus compressus (Gramineae) and then induction medium (IM). Optimum zoospore formation was demonstrated under light microscope after incubation 24 h at 37 degrees C in IM.
Ochroconis globalis, a novel species of the melanized genus (Sympoventuriaceae, Venturiales), is described and illustrated distinguished phenotypically molecularly from existing ochroconis-like species. Phylogenetic analyses using nuclear ribosomal DNA genes (nuSSU, ITS, nuLSU) coding gene fragments (ACT1, BT2, TEF1) revealed clustering all strains as monophyletic clade which was well separated known Most new were obtained human-made environments, while natural habitat remains enigmatic. The...
ABSTRACT Species of Verruconis and species Ochroconis are dematiaceous fungi generally found in the environment but having ability to infect humans, dogs, cats, poultry, fish. This study presents antifungal susceptibility patterns these at level. Forty strains originating from clinical environmental sources were phylogenetically identified level by using sequences ribosomal DNA internal transcribed spacer (rDNA ITS). In vitro testing was performed against eight antifungals, Clinical...
We report the first case and clinical course of a human subcutaneous phaeohyphomycosis caused by Ochroconis tshawytschae, rare fish pathogen. The diagnosis was based upon histopathological mycological examinations samples. Identification etiologic agent assessed on its phenotypic characteristics subsequently, confirmed molecular data. In vitro antifungal susceptibility isolate investigated comparison prepared all features to those two most relevant related species, O. gallopava humicola.
Ochroconis bacilliformis, O. phaeophora and robusta, three novel species of the melanized genus (Sympoventuriaceae, Venturiales), are described, illustrated distinguished phenotypically molecularly from previously described in Ochroconis. Their potential significance for infection cold-blooded vertebrates is discussed.
Recently, the taxonomy of Ochroconis (Ascomycota, Pezizomycotina, Venturiales, Sympoventuriaceae) has been revised with recognition an additional genus, Verruconis. comprises mesophilic saprobes that occasionally infect vertebrates which mostly are cold-blooded, while Verruconis contains thermophilic species is a neurotrope in humans and birds. On basis molecular data it noted only single regularly infects immunocompetent human hosts. Here we report subcutaneous infection due to mirabilis...
Background: The use of a morphological method to determine Aspergillus species in routine laboratory investigation has always been challenged with low sensitivity and specificity. Time-consuming specimen preparation insufficient expertise are the crucial reasons. DNA barcoding markers have introduced for identification as another gold standard method. Objective: To investigate identifying strains isolated from patients eye infection. Methods: This study extracted 12 samples strains. genes,...
An extended molecular phylogeny of the genus Dasymaschalon (Annonaceae) has been reconstructed using up to six plastid DNA regions (matK, ndhF, rbcL exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers). The results unraveled non-monophyly a widely distributed D. dasymaschalum. A lineage dasymaschalum native Java and cultivated at Bogor Botanical Garden represents true dasymaschalum, whereas name Pelticalyx argentea is applicable distantly related clade from mainland Asia. argenteum...
