| [new developments in therapy of deep mycoses]. | over the past two decades the incidence of deep mycoses caused by several major groups of fungal pathogens such as candida spp., aspergilli, cryptococcus neoformans and zygomycetes has risen steadily. moreover, opportunistic fungal infections due to fusarium spp., trichosporon spp., pseudallescheria boydii and other emerging pathogens, as well as fluconazole-resistant candida albicans, all of which are often resistant to existing antifungal drugs, are also encountered more and more frequently. t ... | 2000 | 11064319 |
| pseudallescheria boydii brain abscess successfully treated with voriconazole and surgical drainage: case report and literature review of central nervous system pseudallescheriasis. | pseudallescheria boydii and its asexual form, scedosporium apiospermum, are ubiquitous, saprophytic fungi that commonly cause cutaneous infection. however, in certain circumstances, p. boydii can also cause invasive disease, which can involve the central nervous system (cns). when the cns becomes involved, treatment is difficult, therapeutic options are limited, and the prognosis is poor. we report a case of pseudallescheria brain abscess successfully treated with surgical drainage and systemic ... | 2000 | 11017814 |
| pseudallescheria boydii infection of the nasal cavity of a horse. | an 18-year-old 454-kg (1,000-lb) american quarter horse gelding was evaluated because of chronic intermittent malodorous right-sided nasal discharge. endoscopy revealed a mycotic plaque in the nasal cavity adjacent to the nasomaxillary opening of the right caudal maxillary sinus. the nasomaxillary opening appeared to be larger than normal. fungal culture of specimens of the mycotic plaque yielded pseudallescheria boydii. the horse was treated with 2% miconazole intranasally, sodium iodide i.v., ... | 2000 | 10976304 |
| in vitro susceptibility testing of filamentous fungi: comparison of etest and reference microdilution methods for determining itraconazole mics. | the performance of the etest for itraconazole susceptibility testing of 50 isolates of filamentous fungi was assessed in comparison with the national committee for clinical laboratory standards (nccls) proposed standard microdilution broth method. the nccls method employed rpmi 1640 broth medium, and mics were read after incubation for 48 h at 35 degrees c. etest mics were determined with rpmi agar containing 2% glucose and with casitone agar and were read after incubation for 24 h (aspergillus ... | 2000 | 10970383 |
| molecular variability of pseudallescheria boydii, a neurotropic opportunist. | the sequences of the internal transcribed spacer (its) ribosomal dna (rdna) domain data obtained by restriction fragment length polymorphism analysis with 18s rdna and fingerprinting (m13) for clinical and environmental strains of pseudallescheria boydii (anamorph, scedosporium apiospermum) were compared to those for related species of pseudallescheria, petriella, and scedosporium. the infraspecific variability of p. boydii was considerable. there were five different lengths in the 18s rdnas wit ... | 2000 | 10970369 |
| unusual presentations of isolated sphenoid fungal sinusitis. | isolated sphenoid fungal sinusitis is a rare and often difficult to diagnose condition as the presenting symptoms are often vague and non-specific. in this series each case has a different clinical presentation with a different causative fungus. although isolated fungal sphenoid sinusitis is usually seen in immunocompromised individuals, two of the three cases presented were immunocompetent. the fungi were pseudallescheria boydii, aspergillus fumigatus and schizophyllum commune. in order to illu ... | 2000 | 10912273 |
| meningitis caused by pseudallescheria boydii treated with voriconazole. | meningitis caused by pseudallescheria boydii is an uncommon infection of the cns that usually has a poor prognosis and a difficult treatment. we describe a case of chronic meningitis caused by p. boydii in an immunocompetent host that was successfully treated with voriconazole, a new antifungal agent. | 2000 | 10880322 |
| activity of terbinafine against serious fungal pathogens. | although primarily indicated for dermatophyte infections, the allylamine terbinafine is active in vitro against a broad spectrum of filamentous and dimorphic fungi, in most cases with a primary fungicidal action. using the standard nccls m27-a assay, recent studies confirmed the high activity of terbinafine against dematiaceous fungi and other medically important moulds such as aspergillus and penicillium marneffei. terbinafine displayed a geometric mean mic of 1.4 micrograms/ml against candida ... | 1999 | 10865917 |
| antifungal activity of the new azole uk-109, 496 (voriconazole). | the in vitro activity of voriconazole fully includes aspergillus, and also emerging moulds like fusarium, pseudallescheria boydii, and penicillium marneffei. the minimal inhibitory concentrations of voriconazole for candida krusei and candida glabrata, which are resistant or less susceptible to fluconazole, promise clinical efficacy, although they are ten times higher (0.30-0.39 microgram/ml) than those for candida albicans and other candida spp. (0.001-0.05 microgram/ml). the endemic fungal pat ... | 1999 | 10865910 |
| in-situ detection of aspergillus fumigatus. | an in-situ hybridisation (ish) technique to detect aspergillus fumigatus in infected tissues was developed in which 568-bp, 333-bp and 154-bp pcr products of the alkaline proteinase gene were employed. dot-blot hybridisation with the 568-bp probe on a membrane containing genomic dna from several different fungi including a. flavus, a. niger, penicillium spp., mucor racemosus or pseudallescheria boydii gave negative results. ish was done on formalin-fixed, paraffin-embedded pulmonary tissues from ... | 2000 | 10707949 |
| fungal susceptibility testing. | the utility of antifungal susceptibility testing has not been broadly determined. thus, susceptibility testing of fungal isolates is not recommended on a routine basis. for instance, susceptibilty testing may be considered for some candida species and for patients with pseudallescheria boydii infections. testing of yeasts for susceptiblity to azoles is of particular value due to their variability in response to these agents. it may also be important to test the susceptibility of new fungal organ ... | 1999 | 10571444 |
| case report. atypical cutaneous pseudallescheriosis refractory to antifungal agents. | we report on a 65-year-old male heart transplant recipient who was otherwise in good condition. the patient was immunocompromised secondarily due to cyclosporin, prednisolone and azathioprine when widespread pustular skin lesions with erythematous margins subsequently developed on his left forearm. there was no history of trauma or septic temperature. bacterial cultures were sterile and the results of native and cultural investigation studies were negative. a biopsy specimen of the lesion demons ... | 1999 | 10546493 |
| electrotransformation of the human pathogenic fungus scedosporium prolificans mediated by repetitive rdna sequences. | the regions encoding the 5.8s rrna and the flanking internal transcribed spacers (itsi and itsii) from two isolates of the human pathogenic fungus scedosporium prolificans and one isolate of the taxonomically related species pseudallescheria boydii (s. apiospermum) were sequenced. the sequences of the two s. prolificans isolates were identical. however, there were minor differences between both species. phylogenetic analysis of known fungal sequences confirmed a close relationship between s. pro ... | 1999 | 10459582 |

| prevalence of fungal corneal ulcers in northern india. | fungal corneal ulcer is common in india due to the tropical climate and a large agrarian population that is at risk. various factors such as trauma, the injudicious use of topical antibiotics and corticosteroids are involved. many of the age and sex-related risk factors also play a minor role. this 6-year study from northern india revealed that fungi were detected in 61 (8.4%) out of 730 patients investigated. direct microscopy was positive in 51 (7%) and culture in 53 (7.3%) patients. aspergill ... | 1994 | 7927819 |
| ecology and physiology of the emerging opportunistic fungi pseudallescheria boydii and scedosporium prolificans. | nutritionally physiological patterns of pseudallescheria boydii (microascaceae) and the related species scedosporium prolificans were established. differences between the two species were found in assimilation of sucrose, ribitol, xylitol and l-arabinitol. in contrast, no physiological distinction could be made between the three intraspecific variants of p. boydii which have been recognized on the basis of ndna/dna homology data and of morphological and clinical differences. some potential virul ... | 1994 | 7845423 |
| phylogeny of dermatophytes and dimorphic fungi based on large subunit ribosomal rna sequence comparisons. | the phylogeny of dermatophytes and dimorphic fungi was considered using the large-subunit of ribosomal rna (25s rrna). aligned sequences of 595 nucleotides covering the two most divergent domains d1 and d2, permitted a comparison of phylogenetic relationships at different levels. the dimorphic species (onygenaceae) were significantly separated from dermatophytes (arthrodermataceae) and from a third group including geophilic or very weakly pathogenic species (onygenaceae and gymnoascaceae). on a ... | 1994 | 7844699 |
| invasive pulmonary pseudallescheriasis with direct invasion of the thoracic spine in an immunocompetent patient. | most invasive pseudallescheriasis infections have occurred in immunocompromised patients. the case of an immunocompetent patient with invasive pulmonary pseudallescheriasis and subsequent contiguous extension to the ribs and spine is reported. aspergillosis was mistakenly diagnosed on histopathologic examination of the debrided tissue. culture of the debrided tissue yielded pseudallescheria boydii. | 1994 | 7843180 |
| rapid method for detection of aspergillus 5s ribosomal rna using a genus-specific oligonucleotide probe. | ribosomal rna (rrna) is present in all prokaryotic and eukaryotic cells. although sequences are conserved, variations in nucleic acid composition are known to be species specific. formalin or bouin's fixed, paraffin-embedded tissue specimens from 17 cases of culture proven aspergillus sp infections were studied by a rapid (< 30 minutes) in situ hybridization procedure using a biotinylated oligonucleotide dna probe complementary to nucleic acids 1-22 of aspergillus sp 5s rrna sequence. positivity ... | 1995 | 7817944 |
| ribosomal dna internal transcribed spacer analysis supports synonomy of scedosporium inflatum and lomentospora prolificans. | scedosporium inflatum is a dematiaceous opportunistic pathogen originally described by d. malloch and i.f. salkin (mycotaxon 21:247-255, 1984). however, e. gueho and g. s. de hoog (j. mycol. med. 118:3-9, 1991) recently suggested reducing this mold to synonomy with lomentospora prolificans on the basis of their similar morphological and molecular characteristics. we have investigated the ribosomal dna internal transcribed spacers (its), i.e., its i and its ii, of 18 isolates, including these two ... | 1994 | 7814476 |
| comparative and collaborative evaluation of standardization of antifungal susceptibility testing for filamentous fungi. | the purpose of the study was to evaluate the interlaboratory agreement of broth dilution susceptibility methods for five species of conidium-forming (size range, 2 to 7 microns) filamentous fungi. the methods used included both macro- and microdilution methods that were adaptations of the proposed reference method of the national committee for clinical laboratory standards for yeasts (m27-p). the mics of amphotericin b, fluconazole, itraconazole, miconazole, and ketoconazole were determined in s ... | 1995 | 7726488 |
| in vitro antifungal and fungicidal spectra of a new pradimicin derivative, bms-181184. | a new pradimicin derivative, bms-181184, was compared with amphotericin b and fluconazole against 249 strains from 35 fungal species to determine its antifungal spectrum. antifungal testing was performed by the broth macrodilution reference method recommended by the national committee for clinical laboratory standards (document m27-p, 1992). bms-181184 mics for 97% of the 167 strains of candida spp., cryptococcus neoformans, torulopsis glabrata, and rhodotorula spp. tested were < or = 8 microgra ... | 1995 | 7726485 |
| disseminated cutaneous pseudallescheria boydii. | as increasingly aggressive chemotherapeutic regimens are used to treat malignancy, more patients will become susceptible to various opportunistic pathogens. specifically, several fungal organisms previously viewed as relatively non-pathogenic are more frequently causing serious disease in these patients. identification of these organisms is of paramount importance, as some are relatively resistant to standard antifungal therapies. we report a patient with disseminated cutaneous pseudallescheria ... | 1995 | 7718466 |
| invasive pulmonary pseudallesheriosis in a cross-breed calf. | pulmonary pseudallescheriosis was diagnosed in a two-months old calf. pneumonic lungs with yellow-white nodules on the surfaces revealed granulomatous lesions microscopically. septate, pleomorphic hyphae were present in the central caseated core with a bright eosinophilic periphery surrounded by polymorphonuclear cells and macrophages followed by a zone of epithelioid cells admixed with lymphocytes and plasma cells. the fungal agent was demonstrated by grocott's silver methenamine staining. on i ... | 1994 | 7708091 |
| effect of increasing inoculum sizes of pathogenic filamentous fungi on mics of antifungal agents by broth microdilution method. | inoculum size is a critical variable in development of methods for antifungal susceptibility testing for filamentous fungi. in order to investigate the influence of different inoculum sizes on mics of amphotericin b, 5-fluorocytosine, itraconazole, and miconazole, 32 clinical isolates (8 aspergillus fumigatus, 8 aspergillus flavus, 5 rhizopus arrhizus, 8 pseudallescheria boydii, and 3 fusarium solani isolates) were studied by the broth microdilution method. four inoculum sizes were studied: 1 x ... | 1995 | 7615745 |
| disseminated opportunistic fungal disease in dogs: 10 cases (1982-1990). | medical records of 10 dogs in which fungal infection was diagnosed between 1982 and 1990 were reviewed. in each dog, infection was determined to be caused by a single species of fungus, either aspergillus terreus, penicillium sp, paecilomyces sp, chrysosporium sp, or pseudallescheria boydii. nine dogs were german shepherd dogs; 1 was a german shepherd dog cross, and 9 were females. the most common clinical signs were signs of neck or back pain (9 dogs), weight loss (7 dogs), anorexia (6 dogs), p ... | 1995 | 7601696 |
| chronic hemoptysis: an unusual manifestation of fungal sinusitis. | a woman with chronic hemoptysis as her only complaint had extensive testing and did not respond to antibiotic therapy. radiologic examination of the sinuses identified a mass which, on surgical exploration, was found to be the result of a fungus, pseudallescheria boydii. although this fungus is known to be a cause of epistaxis, this is the first instance in which it has been reported to cause hemoptysis. | 1995 | 7597490 |
| activities of amphotericin b and antifungal azoles alone and in combination against pseudallescheria boydii. | in order to develop new approaches to treatment of infections due to pseudallescheria boydii, the in vitro antifungal activity of amphotericin b alone and in combination with miconazole, itraconazole, and fluconazole was studied. combinations of amphotericin b and antifungal azoles were synergistic, additive, or indifferent in their interaction against p. boydii. antagonism was not observed. | 1995 | 7574531 |
