| recurrent isolation of an uncommon yeast, candida pararugosa, from a sarcoma patient. | a yeast was repeatedly isolated from the saliva of a sarcoma patient. a relatively uncommon species, candida maris, was identified based on the api 20c profile. the yeast species most frequently obtained from the patient's mother and from clinic staff was candida albicans. a comparison of the yeast obtained from the patient with the type strain of c. maris strongly suggested that the former was not representative of c. maris. analysis of partial ribosomal dna sequences of the patient strain and ... | 2004 | 15285058 |
| candida pararugosa isolation from the oral cavity of an italian denture wearer. | candida pararugosa was first isolated from human feces, but after the initial description no further recovery from humans has been reported. during a study on oral candida colonization in denture wearers living in palermo (italy), we isolated c. pararugosa from a 61-year-old woman without signs of oral candidosis. this constitutes, to the authors' knowledge, the first isolation of c. pararugosa from the oral cavity. after six months, colonization by c. pararugosa persisted, suggesting that this ... | 2004 | 15313258 |
| stability of microbial communities in goat milk during a lactation year: molecular approaches. | the microbial communities in milks from one herd were evaluated during 1-year of lactation, using molecular methods to evaluate their stability and the effect of breeding conditions on their composition. the diversity of microbial communities was measured using two approaches: molecular identification by 16s and 18s rdna sequencing of isolates from counting media (two milks), and direct identification using 16s rdna from clone libraries (six milks). the stability of these communities was evaluat ... | 2007 | 17604934 |

| identification and characterization of dekkera bruxellensis, candida pararugosa, and pichia guilliermondii isolated from commercial red wines. | yeast isolates from commercial red wines were characterized with regards to tolerances to molecular so(2), ethanol, and temperature as well as synthesis of 4-ethyl-phenol/4-ethyl-guaiacol in grape juice or wine. based on rdna sequencing, nine of the 11 isolates belonged to dekkera bruxellensis (b1a, b1b, b2a, e1, f1a, f3, i1a, n2, and p2) while the other two were candida pararugosa (q2) and pichia guilliermondii (q3). strains b1b, q2, and q3 were much more resistant to molecular so(2) in compari ... | 2009 | 19835781 |
| occurrence and identification of yeast species in fermented liquid feed for piglets. | the major objective of the present study was to investigate the occurrence and identity of yeast species in fermented liquid feed (flf) used for feeding piglets. in total, 40 different danish farms were included in the analysis. the preparation and composition of flf was found to be very heterogeneous with high variations in both yeast counts and yeast species composition. the yeast population varied between 6.0 × 10(3) and 4.2 × 10(7) cfug(-1) with an average yeast count of 8.7 × 10(6) ± 1.1 × ... | 2011 | 20574824 |
| occurrence and dominance of yeast species in naturally fermented milk from the tibetan plateau of china. | to determine which yeasts are present in the naturally fermented milks of china, 69 samples made by the nomads of tibet were collected from the tibetan plateau in china. from these samples, 225 strains of yeast were isolated and identified using conventional microbiological analysis and gene sequencing analysis of the d1/d2 domain of the large subunit (26s) ribosomal dna. the results showed that the total concentration of yeasts in these samples ranged from 5.01 to 8.97 log10 colony-forming unit ... | 2010 | 20921981 |
| the microbiology of bandji, palm wine of borassus akeassii from burkina faso: identification and genotypic diversity of yeasts, lactic acid and acetic acid bacteria. | to investigate physicochemical characteristics and especially genotypic diversity of the main culturable micro-organisms involved in fermentation of sap from borassus akeassii, a newly identified palm tree from west africa. | 2012 | 22979949 |
| uncommon opportunistic yeast bloodstream infections from qatar. | eleven uncommon yeast species that are associated with high mortality rates irrespective of antifungal therapy were isolated from 17/187 (201 episodes) pediatric and elderly patients with fungemia from qatar. the samples were taken over a 6-year period (january 2004-december 2010). isolated species included kluyveromyces marxianus, lodderomyces elongisporus, lindnera fabianii, candida dubliniensis, meyerozyma guilliermondii, candida intermedia, pichia kudriavzevii, yarrowia lipolytica, clavispor ... | 2014 | 24934803 |
| molecular identification and antifungal susceptibility testing of clinical isolates of the candida rugosa species complex and proposal of the new species candida neorugosa. | candida rugosa is a poorly known fungal species occasionally involved in human infections. a molecular analysis of the sequences of the d1/d2 domains and the internal transcribed spacer (its) region of the ribosomal genes of 24 clinical isolates phenotypically identified as c. rugosa demonstrated that only 10 (41.6%) isolates belonged to that species. the other isolates were identified as candida pararugosa (41.6%) and candida pseudorugosa (8.3%). the remaining two isolates, from human and equin ... | 2012 | 22553236 |
| detection and identification of wild yeast in koumiss. | koumiss is a slightly alcoholic fermented mare's milk beverage, originally obtained by using a natural mixed starter of lactic acid bacteria and yeasts. yeast is an important component of koumiss processing which can affect the aroma, texture, as well as the nutrients beneficial to human health, but few reports have examined the yeast ecology of local ecosystems. the purpose of this study was to isolate and identify the yeast present in koumiss from three representative regions of china using a ... | 2012 | 22608237 |
| a comparative study on the potential of epiphytic yeasts isolated from tropical fruits to produce flavoring compounds. | in recent years, there has been an increasing interest in identifying and characterizing the yeast flora associated with diverse types of habitat because of the many potential desirable technological properties of these microorganisms, especially in food applications. in this study, a total of 101 yeast strains were isolated from the skins of tropical fruits collected in several locations in the south west indian ocean. sequence analysis of the d1/d2 domains of the large subunit (lsu) ribosomal ... | 2015 | 25802220 |
| biosynthesis of single-cell biomass from olive mill wastewater by newly isolated yeasts. | the aim of this study was to assess the potential of newly isolated yeast strains schwanniomyces etchellsii m2 and candida pararugosa bm24 to produce yeast biomass on olive mill wastewater (omw). maximum biomass yield was obtained at 75% (v/v) omw, after 96 h of incubation at 30 °c and 5% (v/v) inoculum size. the optimal carbon/nitrogen (c/n) ratio was in the range of 8:1 to 10:1, and ammonium chloride was selected as the most suitable nitrogen source. under these conditions, a maximum biomass p ... | 2016 | 26662789 |
| candida pararugosa: first reported bloodstream infection in an adult. | candida pararugosa is a yeast that has been previously isolated in various human specimens. the first reported isolation was from human feces in 1998, with subsequent reports of positive cultures from the oral cavity where it was thought to represent colonization rather than true infection. though it has been isolated from other human sites, its clinical significance and manifestations are poorly characterized. we report the case of a 39-year-old woman on parenteral hyperalimentation who develop ... | 2017 | 28680771 |
