The black yeast Exophiala dermatitidis is a frequent agent of colonization of the lungs of patients with cystic fibrosis (CF). A total of 71 clinical isolates of Exophiala from 13 patients were identified at the species level by sequencing the internal transcribed spacer (ITS) regions 1 and 2 of the rDNA genes and typed by random amplification of polymorphic DNA (RAPD), using two different primers, BG-2 and ERIC-1. In vitro susceptibility of these isolates to some systemic antifungal drugs was investigated using the CLSI method. Almost all the isolates were identified as E. dermatitidis, but long-term colonization with the closely related species E. phaeomuriformis was observed in one patient. No clustering was found according to the geographical origin of the isolates, the isolation date or the antifungal susceptibility. Variations were seen in the susceptibility of studied isolates to antifungals but most of them exhibited low susceptibility to amphotericin B and although some patients were

Results: In the present study, the resulting MIC90s for all strains (n = 81) were as follows, in increasing order: posaconazole, 0.125 μg ml-1; itraconazole, 0.25 μg ml-1; voriconazole, 0.5 μg ml-1; amphotericin B, 0.5 μg ml-1; Isavuconazole, 1 μg ml-1; caspofungin, 8 μg ml-1 anidulafungin, 8 μg ml-1 and fluconazole, 16 μg ml-1, without any significant differences in the pattern of susceptibility between environmental and clinical strains (P , 0.05) and genotypes A and B (P , 0.05). The difference in the MIC90s between the two groups of isolates did not differ by more than one dilution. Discussion: Therefore, the present study based on in vitro activity showed that posaconazole and itraconazole might have a potent activity with a best choice of alternative to amphotericin B, for E. dermatitidis cerebral phaeohyphomycosis. In addition, the un-marketing agent Isavuconazole, which is also available as an intravenous preparation, has adequate activity against the latter agent. However, their ...

Phaeohyphomycosis designates fungal infections caused by pheoid or melanized fungi and characterized histopathologically by the presence of septate hyphae, pseudohyphae, and yeasts. Etiologic agents include Exophiala, Phoma, Bipolaris, Phialophora, Colletotrichum, Curvularia, Alternaria, Exserohilum, and Phialemonium sp. The most common are Exophiala jeanselmei and Wangiella dermatitidis. The clinical presentation depends on the immune status of the host: superficial (tinea nigra and black piedra); cutaneous (scytalidiosis) and corneal; subcutaneous (mycotic cyst); and systemic phaeohyphomycosis in the immunocompromised host. The mycotic cyst is a localized form, characterized by subcutaneous asymptomatic nodular lesions that develop after traumatic implantation of fungi, especially on the extremities. The average size of the cysts is 2.5 cm. KOH examination reveals pigmented yeasts, pseudohyphae, and hyphae. A cutaneous biopsy specimen usually shows an abscess or a suppurative granuloma with ...

The majority of mesophilic waterborne species of the black yeast genus Exophiala (Chaetothyriales) belong to a single clade judging from SSU rDNA data. Most taxa are also found to cause cutaneous or disseminated infections in cold-blooded, water animals, occasionally reaching epidemic proportions. Hosts are mainly fish, frogs, toads, turtles or crabs, all sharing smooth, moist or mucous skins and waterborne or amphibian lifestyles; occasionally superficial infections in humans are noted. Cold-blooded animals with strictly terrestrial life styles, such as reptiles and birds are missing. It is concluded that animals with moist skins, i.e. those being waterborne and those possessing sweat glands, are more susceptible to black yeast infection. Melanin and the ability to assimilate alkylbenzenes are purported general virulence factors. Thermotolerance influences the choice of host. Exophiala species in ocean water mostly have maximum growth temperatures below 30 °C, whereas those able to grow until ...

Morphological transitions in Wangiella dermatitidis, a causative agent of human phaeohyphomycosis, influence virulence processes in this polymorphic fungus. My project first involved the cloning and characterizion of the β(1→3) glucan synthase gene WdFKS1, which encodes the enzymes catalytic subunit, followed by cloning and characterizing the WdRHO1 gene, which encodes its regulatory subunit. To better understand the Rho-type GTPase-mediated regulation of cell polarity and its role in fungal morphological transitions, a homologue of WdRAC1 from a W. dermatitidis was subsequently identified by degenerate PCR and gene walking. Gene deletions of WdFKS1 and WdRHO1 in haploid W. dermatitidis were lethal, whereas the deletion of WdRAC1 was not. RNA interference on WdFKS1 mRNA expression resulted in incomplete septa and damaged cell wall integrity, as well as slow growth rate in W. dermatitidis. Overexpression studies, after site-specific integrations of WdRHO1 and WdRAC1 alleles under control of ...

Sample phylogenetic tree of select Exophiala spp. Strain designations are shown at the end of each branch. (Condensed and adapted from Zeng et al., 2007.) To comprehend the evolutionary branching of the isolates, the tree should be viewed from the left to the right. Each bifurcation (branching) of the tree indicates likely evolutionary divergence. The number (known as the bootstrap value) at the point of bifurcation is a percentage based on numerous repeat sequence analyses and indicates the mathematical strength of the grouping; bootstrap values of .90 are shown at the branches. As the tree branches to the right, more closely related isolates ultimately cluster on the same or neighboring branches and are designated in the phylogram as one species. Nucleotide changes that have taken place, expressed as distance, are shown by the scale bar ...

Phaeohyphomycosis is a heterogeneous group of mycotic infections caused by dematiaceous fungi whose morphologic characteristics in tissue include hyphae, yeast-like cells, or a combination of these. It can be associated an array of darkly-pigmented hyphomycetes including Alternaria species, Exophiala jeanselmei, and Rhinocladiella mackenziei. The term phaeohyphomycosis was introduced to determine infections caused by dematiaceous or pigmented filamentous fungi which contain melanin in their cell walls. Phaeohyphomycosis is an uncommon infection, however the number of case reported has been increasing in recent years. The presence of melanin in cell walls may be a virulence factor for the pathogens caused by the fungi. The outcome of antifungal treatment is poor, and mortality is almost 80%. Phaeohyphomycosis has been attributed to more than 100 species and 60 genera of fungi over the past several decades. The pathogens are considered opportunistic. Almost all cases of widely disseminated ...

Dothideaceous black yeast-like fungi (BYF) are known to synthesise DHN-melanin that is inhibited by the systemic fungicide tricyclazole. The final step of the DHN melanin pathway is the conjoining of 1,8-DHN molecules to form the melanin polymer. There are several candidate enzymes for this step, including phenoloxidases such as tyrosinase and laccases, peroxidases, and perhaps also catalases. We analysed the type polyphenoloxidases that are involved in biosynthesis of BYF melanins. For that purpose we used substrates of o-diphenoloxidases (EC 1.10.3.1.): 4-hydroxyphenyl-pyruvic acid, L-β-phenyllactic acid, tyrosine, pyrocatechol, 3,4-dihydroxyphenylalanine and homogentisic acid, as well as substrates of p-diphenoloxidases (EC 1.10.3.2.): syringaldazine, resorcinol, p-phenylenediamine, phloroglucinol, guaiacol and pyrogallic acid. Fourteen strains of black yeasts originating from different natural biotopes were investigated. The tested strains could be divided into four groups based on their ...

Fungi cause disease in plant and animal hosts. The extent to which virulence determinants are conserved between both classes of pathogens is unknown. We have developed a dual plant-animal infection model based on a single strain of Fusarium oxysporum, the causal agent of vascular wilt disease in plants and an emerging opportunistic pathogen of humans. Injection of microconidia of the well-characterized tomato pathogenic isolate 4287 in the lateral tail vein of immunodepressed mice resulted in disseminated infection of multiple organs and death of the animals. Knockout mutants in genes encoding a Pmk1-type mitogen-activated protein kinase, the pH response transcription factor PacC or a class V chitin synthase, all previously shown to be implicated in virulence on tomato plants, were tested in the disseminated mouse model. Our results indicate that some of these virulence factors play functionally distinct roles during infection of tomato and mice. Thus, a single F. oxysporum strain can be used to ...

Phaeohyphomycosis - Etiology, pathophysiology, symptoms, signs, diagnosis & prognosis from the Merck Manuals - Medical Professional Version.

Sequencing of the rRNA genes is indispensable for species recognition in black yeasts and their allies that are causative agents of important human diseases such as chromoblastomycosis and phaeohyphomycosis (1, 2, 8, 21). Several species are known to have reproducible intraspecific polymorphisms in the ITS domain enabling the recognition of variants differing in virulence that are easily detected in an aligned ITS sequence base (16). On the other hand, considerable interspecific polymorphisms may occur between morphologically identical species (5), as phenetically similar structures can be found all over the phylogenetic tree of the Herpotrichiellaceae (9). Sequences may show too much divergence to allow reliable alignment comparison, limiting identification of clinical samples to local BLAST searches. nBlast in GenBank for most species is insufficient, since the taxonomic representation is as yet fragmentary. As yet no molecular marker other than ITS is available with optimal display of ...

To provide scientific evidence for the causal link between indoor airborne fungi and health problems, the full diversity needs however to be identified. This cannot be achieved by using a targeted assay. Therefore, next generation sequencing (NGS) could offer a valuable alternative as an open approach multiplex monitoring method. An NGS-based metagenomics approach was used to investigate the unknown agents in air samples of offices in contact with air-conditioning reservoirs and showed the first detection of E. jeanselmei in indoor air. Finally, a metagenomics analysis was performed to investigate the indoor airborne fungal diversity in contaminated residences in Brussels where people with health problems were living. This demonstrated that NGS could contribute to improved data concerning the indoor airborne fungal diversity, as compared to the currently used classical methods ...

Melatonin (MT), ubiquitous in almost all organisms, functions as a free radical scavenger. Despite several reports on its role as an antioxidant in animals, plants, and some microorganisms, extensive studies in filamentous fungi are limited. Based upon the role of melatonin as an antioxidant, we investigated its role in heavy metal-induced stress tolerance in Exophiala pisciphila, a dark septate endophyte (DSE), by studying the underlying mechanisms in alleviating oxidative stress and reducing heavy metal accumulation. A significant decrease in malondialdehyde (MDA) and oxygen free radical (OFR) in E. pisciphila was recorded under Cd, Zn, and Pb stresses as compared to the control. Pretreatment of E. pisciphila with 200.0 μM exogenous melatonin significantly increased the activity of superoxide dismutase (SOD) under Zn and Pb stresses. Pretreatment with 200.0 μM melatonin also lowered Cd, Zn, and Pb concentrations significantly. Melatonin production was enhanced by Cd, Cu, and Zn after 2 d, and

The favored substrate of Blastomyces dermatitidis appears to be material with a high organic content, with the assumption frequently being made that it, too, must grow within the soil. Developing an understanding of the functions and regulation of such factors is integral to understanding the pathogenesis of disease and could serve as the foundation for innovative approaches to the treatment of fungal infections. The comparison of wild-type strains with strains lacking specific yeast-phase characteristics requires reliable, precise methods of genetic manipulation. Investigation of pathogenesis in B. dermatitidis has required the adaptation of a wide variety of molecular biology tools to this task. The indispensable role of BAD1 in virulence was highlighted through the agency of several molecular genetic tools newly available for use in studies of B. dermatitidis. Cellular immunity is critical in acquired resistance to B. dermatitidis. Mice immunized with either viable or merthiolate-killed yeast

Pullulan is a glucan gum produced by a skin-friendly black yeast that contains polysaccharides, making it a good hydrating ingredient, thickener, and antioxidant in skin care products. Learn more at Paulas Choice.

Pullulan is a non-ionic polysaccharide obtained from fermentation of black yeast like Aureobasidium pullulans and is currently exploited in food and pharmaceutical industries due to its unique characteristics. Due to its properties like non-toxic, non-immunogenic, noncarcinogenic, non-mutagenic, pullulan is being explored for various biomedical applications viz., gene delivery, targeted drug therapy, tissue engineering, wound healing, and also being used in diagnostic applications like, perfusion, receptor, and lymph node target specific imaging and vascular compartment imaging. The unique linkage of α (1→4) and α (1→6) in pullulan endows this polymer with distinctive physical traits, including adhesive property and the ability to form fibres. This review article presents an overview of properties, production, derivatives of pullulan, and recent advances of pullulan.

Coloured scanning electron micrograph (SEM) of Candida albicans infected medical catheter. A common yeast, C. albicans can colonize catheters resulting in serious tissue infections. Shown here is the inner surface of an infected catheter (removed from a patient) revealing a yeast biofilm. Catheters are more commonly infected on the external surface where yeast or bacteria biofilms can easily form. C. albicans is a yeast-like fungus commonly occurring on human skin, in the upper respiratory, alimentary and female genital tracts. This fungus has a dimorphic life cycle with a yeast and hyphal stages. The yeast produces hyphae (strands) from which pseudohyphae branch. The pseudohyphae can give rise to yeast cells by apical or lateral budding. Candida albicans causes candidiasis which includes thrush (an infection of the mouth and vagina) and vulvo-vaginitis.

Other Symptoms. These are also Candida Albicans symptome: headaches, migraine, loss of memory, irritability, constant tiredness, depression, meals allergies, muscle aches, sore / inflamed joints.. What exactly is Candida Albicans and What Causes It?. It is actually the name given to a yeast-like fungus which happens naturally in our bodies, especially in dark, warm, moist regions. It doesnt usually result in any issues for the reason that it really is kept under control by our bodies advantageous bacteria. In some cases even though our very good bacteria can not include the fungus which overgrows, causing the infection that we contact Candida Albicans, Candida, Thrush, Candidiasis or Yeast Infection.. Some of the triggers for an overgrow are factors like; a lowered immune system, also several antibiotics and / or steroids, hormonal changes (e.g. pregnancy), diabetes, unhealthy diet program, soft drugs, some medications, oral contraceptives plus the wearing of damp, sweaty underwear and ...

N-Cadherin and Endocytosis in Candida albicans. I. Introduction/Review. Candida albicans, diploid yeast-like fungi, are harmless commensals of the human body; however, it can also be the causal agent of opportunistic and genital infections known as candidiasis or moniliasis or trush. General-purpose genotype strains (GPGs) of C. albicans has been demonstrated to cause the pathogenic disease more significantly compared to other strains and the predominating effect may be attributed to the ability of the strains to replace the existing commensals (Schmidt and others 1999) and to the differences in the gene region located on 60 alleles of ALS7 ORF or the so-called hypermutable contingency genes (Zhang and others 2003).. The hymatogenous distribution of C. albicans causes allergies in healthy individuals and microabscesses in immunocompromized ...

Vaginal Environment: The normal vaginal environment is slightly acidic and contains friendly bacteria known as Lactobacilli that keep everything in check, but that balance can be easily disrupted by a poor diet, high blood sugars, use of antibiotics, a hormone imbalance or other factors. Imbalances in the pH level in the vagina make it more hospitable to growth of the unhealthy forms of bacteria and parasitic infection. According to Burton Goldberg, Once the balance in vaginal flora has been disrupted, a self-perpetuating cycle is set in motion: as numbers of harmful bacteria decrease (leading to vaginitis), the numbers of friendly bacteria decrease, creating an environment even more vulnerable to infection.. Yeast: Candida albicans, a yeast-like fungus normally found in the intestinal tract and vagina, is also usually held in check by friendly bacteria. However, if the immune system is weakened, or the friendly bacteria have been wiped out by antibiotics, or when transmitted from a sex ...

Overview Intestinal candidiasis is a condition caused by the yeast-like fungus Candida albicans. Candida albicans is referred to as yeast and is normally present in the intestines, blood and vagina. In the gastrointestinal tract, the level of Candida albicans is kept in check by bacteria that is also normally present. An imbalance can cause an…
