antigenic relationship of dactylaria gallopava to scolecobasidium constrictum.dactylaria gallopava and scolecobasidium constrictum were reduced to varietal status under the new combination of dactylaria constricta (abbott) dixon et salkin var. gallopava (cooke) salkin & dixon, and d. constricta (abbott) dixon et salkin var. constricta, primarily on the basis of the morphologic similarity of their two-celled, dematiaceous, blastic conidia. to appraise this taxonomic change, we studied the antigenic relationship of d. gallopava to s. constrictum using the exoantigen procedu ...19902113947
a case of pulmonary cavitary lesion due to dactylaria constricta var. gallopava in a renal transplant patient. 200919356211
fatal systemic phaeohyphomycosis caused by ochroconis gallopavum in a dog (canis familaris).a 5-year-old shetland sheepdog was presented with a history of weakness, ataxia, anemia, thrombocytopenia, and occasional seizures. the dog had been treated for 6 months with prednisone for inflammatory bowel disease. a positive titer for ehrlichia canis was detected 6 months before referral. the initial physical examination revealed a weak, laterally recumbent dog with pale mucous membranes. neurologic examination revealed multiple neurologic deficits. a complete blood cell count (cbc) revealed ...200617099156
optimal testing conditions for determining mics and minimum fungicidal concentrations of new and established antifungal agents for uncommon molds: nccls collaborative study.this collaborative three-center study evaluated nccls m38-a document testing conditions and other testing conditions for the antifungal susceptibility testing of 35 isolates of aspergillus nidulans, a. terreus, bipolaris hawaiiensis, b. spicifera, cladophialophora bantiana, dactylaria constricta, fusarium solani, paecilomyces lilacinus, scedosporium prolificans, trichoderma longibrachiatum, and wangiella dermatitidis for itraconazole, three new triazoles (voriconazole, posaconazole, and ravucona ...200212354880
disseminated dactylaria constricta infection in a renal transplant recipient.we report the case of a 32-year-old renal transplant recipient who developed disseminated dactylaria constricta infection. the patient died despite treatment with amphotericin b, itraconazole, and fluconazole.200111429039
in vitro fungicidal activities of voriconazole, itraconazole, and amphotericin b against opportunistic moniliaceous and dematiaceous fungi.the nccls proposed standard m38-p describes standard parameters for testing the fungistatic antifungal activities (mics) of established agents against filamentous fungi (molds); however, standard conditions are not available for testing their fungicidal activities (minimum fungicidal or lethal concentrations [mfcs]). this study evaluated the in vitro fungistatic and fungicidal activities of voriconazole, itraconazole, and amphotericin b against 260 common and emerging molds (174 aspergillus sp. ...200111230410
infections due to dematiaceous fungi in organ transplant recipients: case report and review.dematiaceous fungi are being increasingly recognized as pathogens in organ transplant recipients. we describe a case of invasive esophagitis due to cladophialophora bantiana in a small bowel transplant recipient and review a total of 34 cases of infections due to dematiaceous fungi in organ transplant recipients. the median time to the onset of fungal infection after transplantation was 22 months. clinically, two distinct patterns of infections were observed: 79% of the patients had skin and/or ...19979114187
phaeohyphomycosis caused by dactylaria (human dactylariosis): report of a case with review of the literature.phaeohyphomycosis due to dactylaria (ochroconis) spp. is a rare infection of man. it was first reported in 1986. all patients have had significant immunosuppression. to our knowledge, this is the second case of phaeohyphomycosis caused by dactylaria constricta var. gallopava in a liver transplant patient and it developed even though he had been receiving fungal prophylaxis with fluconazole. moreover, this case may represent nosocomial acquisition. in addition, we have reviewed the english langua ...19958666840
comparative histopathology of dactylaria constricta, fonsecaea pedrosoi, wangiella dermatitidis, and xylohypha bantiana in experimental phaeohyphomycosis of the central nervous system. 19873614262
dactylaria constricta: another dematiaceous fungus with neurotropic potential in mammals.dacylaria constricta, a neurotropic dematiaceous fungal pathogen of poultry, was evaluated for pathogenic potential in mice. four isolates of d. constricta and two of scolecobasidium humicola were injected intravenously into groups of mice. two isolates of a d. constricta group formerly known as dactylaria gallopava produced signs of central nervous system infection with cerebral microabscesses and death. none of the mice injected with the two remaining isolates of d. constricta from a group for ...19873572683
in vitro and in vivo drug studies with three agents of central nervous system phaeohyphomycosis.amphotericin b (amph b), 5-fluorocytosine (5-fc), ketoconazole (ktz), fluconazole (flz), amorolfine (amor) and terbinafine (ter) were tested against 3 agents of central nervous system phaeohyphomycosis in vitro and in life-threatening infections in mice. the fungi studied were cladosporium bantianum, dactylaria constricta and wangiella dermatitidis. the broadest protection against this group of fungi in mice was offered by 5-fc followed by amph b and flz, then ktz. amor and ter were inactive in ...19873568799
fatal encephalitis caused by dactylaria constricta var. gallopava in a snowy owl chick (nyctea scandiaca).dactylaria constricta var. gallopava (cooke) salkin et dixon was found to cause fatal encephalitis in a 28-day-old, captivity-bred snowy owl chick (nyctea scandiaca). the previously healthy bird suddenly developed ataxia, severe torticollis, and extensor rigidity of the legs. since the animal did not improve with antibiotic or vitamin-mineral supplement therapy, the chick was euthanized 5 days after the onset of neurologic signs. at necropsy, all tissues except the brain were grossly normal. cul ...19902280022
the medically important dematiaceous fungi and their identification.dematiaceous fungi include a large group of organisms that are darkly pigmented (dark brown, olivaceous, or black). in most cases the pigment is melanin, and specifically, dihydroxynaphthalene melanin. the diseases produced include chromoblastomycosis, eumycotic mycetoma, and phaeohyphomycosis. phaeohyphomycosis is a new classification for a diverse group of previously known entities grouped together on the basis of finding dematiaceous hyphal and/or yeast-like forms in tissue; tissue involvemen ...19911922184
dactylaria infection of a human being: pulmonary disease in a heart transplant recipient.we describe a case of pulmonary abscess caused by dactylaria constricta in a heart transplant recipient. a 30-year-old man with a 1-month history of fever and cough was found by computed tomographic scan to have a cavitary lesion in the lingular segment in the upper lobe of his left lung. culture of a needle biopsy specimen yielded a pure culture of d. constricta. the patient was successfully treated with systemic amphotericin b therapy, which resulted in resolution of the clinical symptoms and ...19921498151
