We have studied the virulence and host responses to several clinical and non-clinical Saccharomyces cerevisiae isolates: two vaginal isolates (60, 61), one isolate from faeces (20), a brewer’s yeast isolate used in dietetics (D14), one S. boulardii isolate from a commercial probiotic product, and a reference natural wine yeast (CECT 10431). Hematogenously disseminated infection in a mouse model...

BACKGROUND Neutropenia, as a predisposing factor for invasive candidiasis, is defined as a reduction in neutrophil count to less than 1500/mm3. It is a common condition in patients with hematological malignancy and cytostatic chemotherapy. Extensive chemotherapy and prophylaxis with antifungals have increased the resistance of Candida isolates to antifungal drugs. Although, Candida albicans is ...

BACKGROUND Nigeria is a West African country of more than 150 million persons with the second highest case of HIV/AIDS infected patients in the world. The species spectrum of oral yeast colonization and the susceptibility to a wide range of antifungal agents is poorly understood in Nigeria especially in the south east, south south, and the northern axis. This study evaluates the species spectru...

Introduction: Acne is a pathological disorder and a chronic inflammation in the sebaceous follicles, and one of the most popular dermatology damages that has affected millions of people worldwide. The aim of this study was to identify Candida species in patients with acne as well as determine the drug susceptibility of these species.   Materials & Methods: In this cross-sectional study, 70 cl...

In the present study, growth and total lipid contents of two oleaginous fungal isolates Aspergillus terreus, fumigatus were compared in different nitrogen organic carbon sources. Artificially fungi cultured on media consisting various mono- or di- polysaccharides peptone yeast extract as elementary sources for nitrogen, respectively. Media containing sucrose /yeast glucose/ most effective produ...

Climate, soil, and grape varieties are the primary characteristics of terroir and lead to the definition of various appellations of origin. However, the microbiota associated with grapes are also affected by these conditions and can leave a footprint in a wine that will be part of the characteristics of terroir. Thus, a description of the yeast microbiota within a vineyard is of interest not on...

Several isolates of Gram-positive, acidophilic, moderately thermophilic, ferrous-iron- and mineral-sulphide-oxidizing bacteria were examined to establish unequivocally the characteristics of Sulfobacillus-like bacteria. Two species were evident: Sulfobacillus thermosulfidooxidans with 48-50 mol% G+C and Sulfobacillus acidophilus sp. nov. with 55-57 mol% G+C. Both species grew autotrophically an...

When culturing the pileitrama of young fruit bodies of the two mycoparasitic agarics, Asterophora lycoperdoides (Bull.: Fr.) Ditmar and A. parasitica (Bull.: Fr.) Singer, two tremelloid yeasts were detected (Laaser et al., 1988, 1989; Prillinger, 1987a). The term tremelloid was suggested by Oberwinkler (Laaser et al., 1988; Oberwinkler pers. comm.) for budding yeasts having a cup-shaped parenth...

Six hundred and seventy four yeast isolates obtained from routine microbiological screening of 153 patients with haematological disease were identified and Candida albicans isolates biotyped over nine months to determine longitudinal and cross sectional patterns of yeast colonisation. A yeast microflora persisted in many patients despite the routine prophylactic use of oral antifungal agents. A...
