molecular and phenotypic characterization of phialemonium and lecythophora isolates from clinical samples.several members of the fungal genera phialemonium and lecythophora are occasional agents of severe human and animal infections. these species are difficult to identify, and relatively little is known about their frequency in the clinical setting. the objective of this study was to characterize morphologically and molecularly, on the basis of the analysis of large-subunit ribosomal dna sequences, a set of 68 clinical isolates presumed to belong to these genera. a total of 59 isolates were determi ...201121270235
use of microfungi in the treatment of oak chips: possible effects on wine.oak barrels are commonly used in the aging of wines and spirits because of their positive effects on the product. in recent years the addition of oak chips has been used to introduce desirable wood aromas and flavours into wines. in this study, oak chips in saline solution or laboratory medium were inoculated with penicillium purpurogenum, aureobasidium pullulans, phialemonium obovatum, phanerochaete chrysosporium and a combination of ph. chrysosporium and a. pullulans. after 12 weeks of incubat ...201020718033
lung infection due to opportunistic fungus, phialemonium obovatum, in a bone marrow transplant recipient: an emerging infection with fungemia and crohn disease-like involvement of the gastrointestinal tract.we report the first case of phialemonium obovatum fungemia with subsequent caseating granulomatas in the lung and crohn disease-like involvement of the gastrointestinal tract in a bone marrow transplant recipient. this phaeoid fungus has been rarely described as an opportunistic infection in immunosuppressed patients. the patient was diagnosed with chronic myelogenous leukemia and underwent subsequent peripheral bone marrow transplant. after 6 months, he developed graft-versus-host disease of th ...200516084458
fatal endocarditis in a neonate caused by the dematiaceous fungus phialemonium obovatum: case report and review of the literature.phialemonium species are grouped by most authorities among the dematiaceous fungi. like several other darkly pigmented fungi, they appear to be an emerging cause of human disease, especially in the immunocompromised host. as numbers of immunocompromised patients increase, the trend of unusual fungi emerging as new pathogens is set to continue. previous experience suggests that reports of rare fungal infections among selected patients often heralds the emergence of infection in a wider population ...200212037088
disseminated infection with phialemonium obovatum in a german shepherd dog.a 4-year-old spayed female german shepherd dog was evaluated because of left forelimb lameness. a fungal granuloma on the distal portion of the radius was determined to be the cause of the lameness; the infecting organism was identified as phialemonium obovatum. despite aggressive treatment with amphotericin b, itraconazole, and ketoconazole and curettage of the local area, the dog developed systemic disease and was euthanatized 5 months after initial evaluation. immune dysfunction may have play ...200010707686
a phaeohyphomycotic cyst and peritonitis caused by phialemonium species and a reevaluation of its taxonomy.two cases of human fungal infections caused by members of the genus phialemonium, a genus proposed by gams and mcginnis (1983) for fungi intermediate between the genera acremonium and phialophora, are presented. the first case was a phaeohyphomycotic cyst on the foot of a renal transplant recipient. the fungus was detected by direct examination and histopathology and was recovered by several procedures over 4 months. it was flat, glabrous, and white becoming yellow with the production of a diffu ...19938349757
osteolytic phaeohyphomycosis caused by phialemonium obovatum.phialemonium obovatum was found to be the cause of nosocomial osteomyelitis in a 41-year-old man after sustaining a nonpenetrating injury to his lumbar and cervical region. histologic examination of fragments of disk and bone from l3-4 hemilaminectomy showed multiple fragments of fibrocartilage with focal necrosis, chronic inflammation, and granulation tissue formation. sections stained with gomori's methenamine silver procedure showed multiple fungal elements in necrotic areas consisting of irr ...19938343050
osteolytic phaeohyphomycosis in a german shepherd dog caused by phialemonium obovatum.phialemonium obovatum was found to be the cause of osteomyelitis in a german shepherd dog. histologic examination of the biopsied material from the left tibia revealed septate, irregularly branched hyphae, swollen cells, and ovate-to-spherical cells divided by a transverse septum. the majority of the fungal elements were hyaline, but a few had lightly pigmented cell walls that had a greenish yellow tint. the presence of melanin in the cell walls of the hyphae and especially in their septa was ve ...19863711290
phialemonium obovatum infection in a burned child.phialemonium obovatum is reported for the first time as an opportunistic fungal pathogen of man. the fungus was recovered from biopsy specimens consisting of cutaneous and subcutaneous tissue obtained from thermal burn wounds antemortem and from spleen tissue and three burn sites postmortem. the hyaline hypae of p. obovatum were seen invading viable tissue and blood vessels. the taxonomy of the genus phialemonium and the criteria for determining fungal burn wound invasion are discussed.19863701542
phialemonium obovatum keratitis after penetration injury of the cornea.phialemonium keratitis is a very rare case and we encountered a case of keratitis caused by phialemonium obovatum (p. obovatum) after penetrating injury to the cornea. this is the first case report in the existing literature. a 54-year-old male was referred to us after a penetration injury, and prompt primary closure was performed. two weeks after surgery, an epithelial defect and stromal melting were observed near the laceration site. p. obovatum was identified, and then identified again on rep ...201223204804
