The new anamorphic yeast Kuraishia piskuri, f.a., sp. nov. is described for three strains that were isolated from insect frass from trees growing in Florida, USA (type strain, NRRL YB-2544, CBS 13714). Species placement was based on phylogenetic analysis of nuclear gene sequences for the D1/D2 domains of large subunit rRNA, small subunit rRNA, translation elongation factor-1α, and subunits B1 a...

Hopanoids are pentacyclic triterpenoid lipids synthesized by different bacterial groups. Methylated hopanoids were believed to be exclusively synthesized by cyanobacteria and aerobic methanotrophs until the genes encoding for the methylation at the C-2 and C-3 position (hpnP and hpnR) were found to be widespread in the bacterial domain, invalidating their use as specific biomarkers. These genes...

The in vitro activity of the azasordarin GW 471558 was compared with those of amphotericin B, flucytosine, itraconazole, and ketoconazole against 177 clinical isolates of Candida spp. GW 471558 showed potent activity against Candida albicans, Candida glabrata, and Candida tropicalis, even against isolates with decreased susceptibility to azoles. Candida krusei, Candida parapsilosis, Candida lus...

OBJECTIVE To identify Candida species in asymptomatic subjects in Bobo-Dioulasso (Burkina Faso) by the matrix-assisted laser desorption ionization-time of flight mass spectrometry. METHODS A cross-sectional study was conducted from January to February 2013 in Bobo-Dioulasso to collect fecal and urine specimens from voluntary donors. Fungal strains were isolated on Sabouraud dextrose agar and ...

background and objectives: vulvovaginal candidiasis is a common fungal infection among women during reproductive ages. although, candida albicans is accounted as the main etiologic agent of vaginitis, non- albicans species have arisen during last years. resistant to antifungal drugs especially, fluconazole has been more reported by researchers from around the world. the aims of this study were ...

A major clade of new yeast taxa from the digestive tract of basidiocarp-feeding beetles is recognized based on rRNA gene sequence analyses. Almost 30 % of 650 gut isolates formed a statistically well-supported clade that included Candida tanzawaensis. The yeasts in the clade were isolated from 11 families of beetles, of which Tenebrionidae and Erotylidae were most commonly sampled. Repeated iso...

The RapID Yeast Plus System (Innovative Diagnostic Systems, Norcross, Ga.) is a qualitative micromethod that uses conventional and chromogenic substrates for the identification of medically important yeasts. The ability of the RapID Yeast Plus system to accurately identify 304 clinical yeast isolates within 5 h was evaluated. The RapID Yeast Plus method correctly identified 286 (94.1%) of strai...

Fungicidal effects of histatin-5 against 26 oral isolates belonging to 5 non-albicans Candida species were examined. Fifty microM of histatin-5 killed more than 95% of Candida tropicalis and Candida guilliermondii isolates and more than 90% of Candida parapsilosis and Candida krusei. However, Candida glabrata was less sensitive to the peptide (mean 62.9%). Our results, taken together, demonstra...
