Candida parapsilosis is an emerging fungal pathogen that was once thought to be solely a colonizing organism. C. parapsilosis is increasingly becoming reported as the most common Candida species that causes onychomycosis. Clinical findings include typically severe dystrophy of the nail fold and plate as well as thickening and fragmentation of the plate, particularly in the distal plate. We pres...
The activity of usnic acid against Candida orthopsilosis and Candida parapsilosis on planktonic and biofilm conditions was investigated by using a broth microdilution and microplate methods. Potent in vitro activities against different Candida species were obtained. The metabolic activity of sessile cells of C. parapsilosis complex was reduced by 80% at four times the 80% inhibitory concentrati...
The aim of this study was to evaluate the sensitivity and the levels of 1,3-β-d-glucan (BDG) among patients with candidaemia due to different Candida species. Retrospective study of all patients who had a single-species candidaemia and BDG testing performed within 48 h from the onset of candidaemia during 2009-2015 was performed. Factors influencing the sensitivity of BDG, including the presenc...
Background: Over the last two decades invasive candidiasis has become an increasing problem in neonatal intensive care units (NICUs). Colonization of skin and mucous membranes with Candida spp. is important factor in the pathogenesis of neonatal infection and several colonized sites are major risk factors evoking higher frequencies of progression to invasive candidiasis. The aim of this study w...
Candida species are common causes of bloodstream infections (BSI), with high mortality. Four species cause >90% of Candida BSI: C. albicans, C. glabrata, C. parapsilosis, and C. tropicalis. Differentiation of Candida spp. is important because of differences in virulence and antimicrobial susceptibility. Candida QuickFISH BC, a multicolor, qualitative nucleic acid hybridization assay for the ide...
Among the Candida species, Candida parapsilosis has a unique mitochondrial respiratory network. The addition of inhibitors of the respiratory pathways in three clinical isolates of C. parapsilosis with high (> or =2- microg/ml) MICs of caspofungin significantly (fivefold) decreased caspofungin MICs but did not change fluconazole MICs.
An increase in the rate of isolation of Candida parapsilosis, relative to other Candida species, in our children's hospital led us to analyze the clinical and epidemiological variables associated with candidemia. We sought to determine if these variables are different for patients infected with C. parapsilosis. All episodes of candidemia occurring over a 7-year period were analyzed retrospectiv...
A 30-min fluorogenic test was developed for differentiation of members of the Candida parapsilosis group from other Candida species commonly encountered in clinical material. The fluorogenic substrate, 4-methylumbelliferyl-beta-D-glucoside, was utilized to assay beta-glucosidase activity. A total of 50 C. parapsilosis isolates and 135 isolates of four other Candida species were tested. Assay se...
