| a pseudoepidemic of sporothrix cyanescens pneumonia occurring during renovation of a bronchoscopy suite. | sporothrix cyanescens, an uncommonly isolated mold, was cultured from biopsy tissue, bronchial washings and sputum obtained at bronchoscopy from four patients during a one-month period. these patients had undergone fiberoptic bronchoscopy to aid in the diagnosis of pneumonic infiltrates. during this period of time the bronchoscopy suite was being extensively renovated. cultures of bronchoscopes, biopsy forceps and effluents from the bronchoscopy injection ports were negative for fungi, as were a ... | 1990 | 2093118 |
| microbiology and potential virulence of sporothrix cyanescens, a fungus rarely isolated from blood and skin. | sporothrix cyanescens has been recovered from blood and a finger lesion at several medical centers in the united states. the morphology and physiology of these and three additional isolates were studied. s. cyanescens was distinguished from s. schenckii and s. fungorum by white to lavender colonial pigmentation and from s. schenckii also by the formation of secondary conidia. all isolates of s. cyanescens grew well at 37 degrees c, were cycloheximide susceptible, strongly urease positive, and be ... | 1990 | 2351719 |
| possible pathogenic role for sporothrix cyanescens isolated from a lung lesion in a heart transplant patient. | sporothrix cyanescens is a fungus rarely isolated from human specimens. its pathogenic role has never been demonstrated but has been postulated on the basis of its occurrence in normally sterile body sites, its isolation from debilitated individuals and its thermotolerance. a first case of nodular pulmonary lesions developing in an immunosuppressed, heart transplant patient is reported. sporothrix cyanescens was isolated from a fine needle lung biopsy. the patient failed to respond to itraconazo ... | 1996 | 8803800 |
| identity and biodegradative abilities of yeasts isolated from plants growing in an arid climate. | plants harvested in the canary islands lanzarote and fuerteventura were analyzed for the yeasts inhabiting their surface. half of the isolates (22 out of 44) were identified as debaryomyces hansenii. black ascomycetes, viz. hortaea werneckii and two hormonema species were represented by 7 strains. basidiomycetous yeasts, viz. cryptococcus sp. (8 strains), rhodotorula sp. (5 strains), cerinosterus cyanescens (1 strain) and pseudozyma sp. (1 strain) constituted a minority of 33%. thirty strains we ... | 1997 | 9298186 |
| prevalence and outcome of invasive fungal infections in 1,963 thoracic organ transplant recipients: a multicenter retrospective study. italian study group of fungal infections in thoracic organ transplant recipients. | fungal infections (fi) after solid organ transplantation (tx) remain a major cause of morbidity and mortality. aspergillus and candida account for more than 80% of fi. | 2000 | 10919584 |
| phylogenetic position and physiology of cerinosterus cyanescens. | partial 25s rrna sequencing of cerinosterus cyanescens showed it to be a close relative of microstroma juglandis, a member of the basidiomycetous order microstromatales. it is unrelated to the generic type species, c. luteoalba, which is a member of the order dacrymycetales. the clinical occurrence of c. cyanescens is possibly explained by its thermotolerance and lipolytic activity. the species' nutritional profile is established. growth on n-hexadecane is rapid; it grows well on typical plant c ... | 2000 | 10959560 |
| production of (+)-globulol needle crystals on the surface mycelium of quambalaria cyanescens. | the structure of unique colorless needle crystals growing from the surface mycelium of the basidiomycete quambalaria cyanescens and identified as (+)-globulol was followed by mass spectrometry, x-ray diffraction, and polarimetry. the mechanism of (+)-globulol fragmentation is proposed based on collision induced dissociation mass spectrometry. x-ray analysis revealed that crystal packing is governed by hydrogen bond o-h.....o connecting the molecules into an infinite helix along a 3-fold screw ax ... | 2008 | 18481213 |
| phylogeny of the quambalariaceae fam. nov., including important eucalyptus pathogens in south africa and australia. | the genus quambalaria consists of plant-pathogenic fungi causing disease on leaves and shoots of species of eucalyptus and its close relative, corymbia. the phylogenetic relationship of quambalaria spp., previously classified in genera such as sporothrix and ramularia, has never been addressed. it has, however, been suggested that they belong to the basidiomycete orders exobasidiales or ustilaginales. the aim of this study was thus to consider the ordinal relationships of q. eucalypti and q. pit ... | 2006 | 18490987 |
| identification and characterization of a rare fungus, quambalaria cyanescens, isolated from the peritoneal fluid of a patient after nocturnal intermittent peritoneal dialysis. | peritonitis is the leading complication of peritoneal dialysis, which is primarily caused by bacteria rather than fungi. peritonitis is responsible for approximately 18% of the infection-related mortality in peritoneal dialysis patients. in this paper, we report the isolation of a rare fungus, quambalaria cyanescens, from the peritoneal fluid of a man after he switched from continuous ambulatory peritoneal dialysis to nocturnal intermittent peritoneal dialysis. based on the morphological examina ... | 2015 | 26716988 |
| biologically active metabolites produced by the basidiomycete quambalaria cyanescens. | four strains of the fungus quambalaria cyanescens (basidiomycota: microstromatales), were used for the determination of secondary metabolites production and their antimicrobial and biological activities. a new naphthoquinone named quambalarine a, (s)-(+)-3-(5-ethyl-tetrahydrofuran-2-yliden)-5,7,8-trihydroxy-2-oxo-1,4-naphthoquinone (1), together with two known naphthoquinones, 3-hexanoyl-2,5,7,8-tetrahydroxy-1,4-naphthoquinone (named here as quambalarine b, 2) and mompain, 2,5,7,8-tetrahydroxy-1 ... | 2015 | 25723150 |
| a rare fungal species, quambalaria cyanescens, isolated from a patient after augmentation mammoplasty--environmental contaminant or pathogen? | some emerging but less common human fungal pathogens are known environmental species and could be of low virulence. meanwhile, some species have natural antifungal drug resistance, which may pose significant clinical diagnosis and treatment challenges. implant breast augmentation is one of the most frequently performed surgical procedures in china, and fungal infection of breast implants is considered rare. here we report the isolation of a rare human fungal species, quambalaria cyanescens, from ... | 2014 | 25330078 |
| quambalarine b, a secondary metabolite from quambalaria cyanescens with potential anticancer properties. | quambalarine b (qb) is a secondary metabolite produced by the basidiomycete quambalaria cyanescens with potential anticancer activity. here we report that qb at low micromolar concentration inhibits proliferation of several model leukemic cell lines (jurkat, nalm6, and reh), whereas higher concentrations induce cell death. by contrast, the effect of qb on primary leukocytes (peripheral blood mononuclear cells) is significantly milder with lower toxicity and cytostatic activity. moreover, qb inhi ... | 2016 | 27571379 |
| [report of quambalaria cyanescens associated with birch]. | long-term microbiological investigation of the pollen of silver birch (betula pendula) in the mos- cow, and moscow region areas revealed that: almost one-third of the analyzed samples, contained the fungus identified by morphological, cultural, and molecular genetic techniques as quambalaria cyanescens (de hoog & g. a. de vries) z.w. de beer, begerow & r. bauer. this species was previously known mostly as a syrmbiont of tropical plants of the generaeucalyptus and cortyminbia and has not been iso ... | 2015 | 25844472 |
| mutagenic breeding of quambalaria cyanescens strain for the production of milk-clotting enzymes. | a strain for producing rennet was screened from red kojic rice and identified as quambalaria cyanescens. in the current work, various mutagenic treatments, such as uv, diethyl sulfate and their combinations were applied for improving the production of milk-clotting enzymes. the mutagenic conditions were optimized based on the fatality rate of the strain. a significant increasing in the productivity of the fungal rennet produced from the strain quambalaria cyanescens was achieved and its milk-clo ... | 2014 | 24816696 |
