We report a case of spondylodiscitis and spinal abscess following haematogenous dissemination of the emerging yeast Candida dubliniensis in a human immunodeficiency virus-1 (HIV-1) and hepatitis C virus (HCV)-coinfected patient. Although C. dubliniensis is considered less virulent compared to its closest known relative Candida albicans, reports of severe fungal infections are increasing. This c...
Candida dubliniensis is the closest known relative of Candida albicans, the most pathogenic yeast species in humans. However, despite both species sharing many phenotypic characteristics, including the ability to form true hyphae, C. dubliniensis is a significantly less virulent and less versatile pathogen. Therefore, to identify C. albicans-specific genes that may be responsible for an increas...
Seven isolates each of Candida albicans and Candida dubliniensis were paired (11 pairs) and examined for competitive interaction. Equal numbers of CFU of each competitor were inoculated into Sabouraud dextrose broth and incubated at 37 degrees C with vigorous shaking under conditions favorable to either broth or biofilm growth. Surviving proportions of each competitor were calculated from the b...
The development of a satisfactory means to reliably distinguish between the two closely related species Candida albicans and Candida dubliniensis in the clinical mycology laboratory has proved difficult because these two species are phenotypically so similar. In this study, we have detected homologues of the pH-regulated C. albicans PHR1 and PHR2 genes in C. dubliniensis. Restriction fragment l...
1Department of Microbiology, Omar Medical Laboratories, Amman, Jordan (Correspondence to O.M. Momani: [email protected]). King Hussein Medical Centre, Amman, Jordan. Received: 09/10/02; accepted: 14/09/03 ABSTRACT Candida dubliniensis is an emerging yeast pathogen isolated mainly from immunocompromised patients. As molecular tests are currently unsuitable for use in routine diagnostic labo...
A nine-year prospective study (2002-2010) on the prevalence of Candida dubliniensis among Candida bloodstream isolates is presented. The germ tube positive isolates were provisionally identified as C. dubliniensis by presence of fringed and rough colonies on sunflower seed agar. Subsequently, their identity was confirmed by Vitek2 Yeast identification system and/or by amplification and sequenci...
OBJECTIVES Novel highly functionalized bis cyclohexenone ethyl carboxylates 7-12 were designed, synthesized and their structures were elucidated by their elemental analysis, MS, FT-IR, one-dimensional 1H, and 13C NMR spectroscopic data. MATERIALS AND METHODS All the synthesized compounds 7-12 were tested for their in vitro antifungal activities against Candida sp. namely Candida albicans, Can...
Morphogenesis control by chemical signaling molecules is beginning to be highlighted in Candida biology. The present study focuses on morphogenic compounds produced in situ by Candida albicans and Candida dubliniensis during planktonic and biofilm growth that may at least partially substantiate the effect promoted by supernatants in morphogenesis. For both species, planktonic versus biofilm sup...
INTRODUCTION Biofilm production is considered a potential virulence factor of some Candida species. For this reason, an understanding of biofilm behavior of Candida albicans and its closely related species Candida dubliniensis is key to the development of effective preventive measures for invasive and oral candidiasis. The aim of this study was to compare the capacity of biofilm production by b...
The aim of this study was to report the ability of killer toxins, previously used as biotyping techniques, as a new tool to differentiate C. albicans from C. dubliniensis. The susceptibility of C. albicans and C. dubliniensis to killer toxins ranged from 33.9 to 93.3% and from 6.67 to 93.3%, respectively.
