Validation of the species Pichia guilliermondii.
Many species of yeasts exist in nature in haploid form. If strongly heterothallic, strains of such species produce no ascospores when tested individually. They do mate if sexually reactive strains of opposite sex are mixed on a sporulation medium. In 1952, L. J. Wickerham and K. A. Burton (J. Bacteriol. 63:449, 1952) reported that all strains of an imperfect form known variously as Dematium cho...
متن کاملMolecular typing of the yeast species Dekkera bruxellensis and Pichia guilliermondii recovered from wine related sources.
A total of 63 strains of Dekkera bruxellensis and 32 strains of Pichia guilliermondii isolated from wine related environments were identified by restriction analysis of the 5.8S-ITS region of the rDNA. These strains were subjected to intraspecific discrimination using mtDNA restriction and RAPD-PCR analysis. The isolates identified as D. bruxellensis yielded 3 different molecular patterns of mt...
متن کاملMolecular identification of Pichia guilliermondii, Debaryomyces hansenii and Candida palmioleophila
Traditional phenotypic methods and commercial kits based on carbohydrate assimilation patterns are unable to consistently distinguish among isolates of Pichia guilliermondii, Debaryomyces hansenii and Candida palmioleophila. As result, these species are often misidentified. In this work, we established a reliable method for the identification/differentiation of these species. Our assay was vali...
متن کاملDebaryomyces hansenii (Candida famata), a rare human fungal pathogen often misidentified as Pichia guilliermondii (Candida guilliermondii).
Debaryomyces hansenii is a hemiascomycetous yeast commonly found in natural substrates and in various types of cheese. Pichia guilliermondii is widely distributed in nature and is a common constituent of the normal human microflora. Both species have been described in human infections but are extremely difficult to differentiate phenotypically. Thus, frequent errors in identification occur. The...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
