| evaluation of the api 20c yeast identification system for the differentiation of some dematiaceous fungi. | ninety-seven isolates of cladosporium spp., exophiala spp., fonsecaea spp., lecythophora hoffmannii, phaeoannellomyces werneckii, phialophora spp., wangiella dermatitidis, and xylohypha bantiana were used to evaluate the api 20c yeast identification system for the differentiation of dematiaceous fungi. using the api 20c system, we were able to distinguish most species of phialophora and cladosporium and to separate l. hoffmannii from the species of phialophora tested; x. bantiana from c. carrion ... | 1989 | 2808678 |
| exoantigen test for cladosporium bantianum, fonsecaea pedrosoi, and phialophora verrucosa. | exoantigens from 10-day-old cultures of 100 isolates of pathogenic and saprophytic dematiaceous fungi were analyzed by the exoantigen test. antisera to cladosporium bantianum atcc 10958, fonsecaea pedrosoi cdc amo-b06, and phialophora verrucosa cdc amo-c12 were prepared in new zealand rabbits immunized with soluble antigens from 1-month-old cultures. absorbed and nonabsorbed antisera and exoantigens from the same organisms were used as reference reagents. serologic reactions were analyzed in ter ... | 1986 | 3084549 |
| evaluation of proteolytic activity to differentiate some dematiaceous fungi. | a total of 123 isolates of cladosporium spp., exophiala spp., fonsecaea spp., lecythophora hoffmannii, phaeoannellomyces werneckii, phialophora spp., wangiella dermatitidis, and xylohypha bantiana were tested for proteolytic activity by using 26 different formulations of gelatin, milk, casein, and loeffler media. other physiological properties examined included hydrolysis of tyrosine and xanthine, sodium nitrate utilization in czapek dox agar, and thermotolerance. isolates of exophiala jeanselme ... | 1988 | 3343325 |
| gluteal abscess caused by phialophora hoffmannii and review of the role of this organism in human mycoses. | infections caused by members of the phialophora hoffmannii (beyma) schol-schwarz fungal aggregate (a group of related taxa, especially species of uncertain circumscription) are not reported frequently. this case report concerns the development of a gluteal abscess after multiple intramuscular injections of antimicrobial agents. microbiological examination of the abscess material yielded a pure growth of the mold p. hoffmannii. hyphal elements in the purulent exudate were only demonstrated when t ... | 1982 | 7107854 |
| scytalidium dimidiatum and lecythophora hoffmannii: unusual causes of fungal infections in a patient with aids. | immunocompromised patients are susceptible to infections by fungi that seldom cause disease in humans. we describe a human immunodeficiency virus-infected patient who had simultaneous infections with two fungi which are rare causes of serious infection: lecythophora hoffmannii, causing chronic sinusitis, and scytalidium dimidiatum, causing skin lesions, lymphangitis, and lymphadenitis. the clinical and pathologic findings are discussed. | 1997 | 9350765 |
| novel use of a swimming pool biocide in the treatment of a rare fungal mastoiditis. | to describe an extremely rare fungal mastoiditis caused by lecythophora hoffmannii, its recalcitrant behavior to therapy, and eventual successful treatment with adjunctive therapy using polyhexamethylene biguanide (a common swimming pool biocide). | 2005 | 15933522 |
| phenolic compound utilization by the soft rot fungus lecythophora hoffmannii. | nine phenolic compounds were metabolized by the soft rot fungus lecythophora hoffmannii via protocatechuic acid and subsequently cleaved by protocatechuate 3,4-dioxygenase as determined by oxygen uptake, substrate depletion, and ring cleavage analysis. catechol was metabolized by catechol 1,2-dioxygenase. fungal utilization of these aromatic compounds may be important in the metabolism of wood decay products. | 1988 | 16347701 |
| lecythophora hoffmannii isolated from a case of canine osteomyelitis in japan. | a 2-year-old spayed female mongrel dog showed claudication with abnormal ossification containing fungal cells detected by biopsy. the dog was treated with ketoconazole and itraconazole perorally for 5 months; however, the osteomyelitis became aggravated, and an amputation from the scapula was performed. the right superficial cervical lymph node became swollen 5 months after the operation. the lymph node contained pas positive fungal elements and a portion of tissue produced mycelial fungal growt ... | 2007 | 17464847 |
| 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 ... | 2011 | 21270235 |
| lc-ms method for screening unknown microbial carotenoids and isoprenoid quinones. | the structure of secondary metabolites from microorganisms provides a useful tool for microbial characterization and chemotaxonomic classification. microbial isoprenoid quinones, for example, are well described and used to distinguish among photosynthetic microorganism groups. in addition, isoprenoid quinones can also be found, together with carotenoids, in non-photosynthetic microorganisms. the aim of the present study was to develop a lc-ms/ms method which can analyze and identify these microb ... | 2012 | 22036764 |
| diversity and distribution of cultured endolichenic fungi in the ny-ålesund region, svalbard (high arctic). | endolichenic fungi within 17 lichen species in the area near ny-ålesund (svalbard, high arctic) were studied by a culture-based method. the 247 fungal isolates were obtained from 2712 lichen thallus segments. the colonization rate of endolichenic fungi ranged from 1.6 to 26.5 %, respectively. these isolates were identified to 40 fungal taxa, including 35 ascomycota (10 orders), 4 basidiomycota (3 orders), and 1 unidentified fungus. thelebolales was the most abundant order, while sordariales were ... | 2016 | 27240672 |
