| evidence for possible involvement of an elastolytic serine protease in aspergillosis. | a number of isolates of aspergillus fumigatus obtained from the hospital environment produced extracellular elastolytic activity. this activity was found to be catalyzed by a single 33-kda protein which was purified and characterized to be a serine protease. a. fumigatus, when grown on the insoluble structural material obtained from murine and bovine lung, produced the same extracellular 33-kda elastolytic protease, indicating that this enzyme is likely to be produced when the organism infects t ... | 1993 | 8500876 |
| pradimicins t1 and t2, new antifungal antibiotics produced by an actinomycete. i. taxonomy, production, isolation, physico-chemical and biological properties. | pradimicins t1 and t2, new members of the pradimicin family of antibiotics, were produced by an actinomycete strain aa3798. pradimicin t1 exhibited potent activity against a wide spectrum of fungi in vitro and demonstrated efficacy against systemic candida albicans and aspergillus fumigatus infections in mice. | 1993 | 8501001 |
| application of polymerase chain reaction to fingerprinting aspergillus fumigatus by random amplification of polymorphic dna. | a new method for fingerprinting aspergillus fumigatus by random amplification of polymorphic dna (rapd) by using single primers with arbitrary sequences is described. five primers were examined with 19 isolates from six patients with aspergilloma as well as with a. fumigatus ncpf 2109. two of the primers (gct ggt gg and gcg cac gg, 5' to 3') gave adequate discrimination between isolates, generating five and six types, respectively. combination of the results obtained with each of these two prime ... | 1993 | 8501211 |
| infectious disease rounds: pneumonia due to aspergillus. | angioinvasive fungi, like aspergillus, can cause invasive infections in patients immunosuppressed by steroid therapy. pulmonary infarction, manifested as pleuritic chest pain, frequently results from in situ thrombosis and is characteristic of aspergillus pneumonia. | 1993 | 8506105 |

| immunoblot analysis of aspergillus fumigatus antigen with human antibodies and lectin probes. | components of culture filtrate antigen of aspergillus (a.) fumigatus were electrophoretically separated, transferred to hydrophobic durapore membrane, and then probed with patients' sera and lectins. using human sera from patients with aspergilloma and allergic bronchopulmonary aspergillosis (abpa), more than 13 igg binding components were identified. igg binding to high molecular weight components (hmw) of over 30 kda was observed in all patient sera tested, but igg binding to low molecular wei ... | 1993 | 8507937 |
| airborne dust and aeroallergen concentration in a horse stable under two different management systems. | airborne dust concentration (adc) was measured in 2 different horse management systems using an andersen cascade impactor in the box-stall, and a personal marple cascade impactor attached to the halter to measure adc in the breathing zone. the levels of aeroallergens implicated in chronic obstructive pulmonary disease were measured by radioallergosorbent-inhibition immunoassay. a conventional management system (system c) utilising hay feed and straw bedding, and a recommended environment (system ... | 1993 | 8508749 |
| liposomal hamycin in the control of experimental aspergillosis in mice: effect of phosphatidic acid with and without cholesterol. | hamycin incorporated into liposomes containing phosphatidylcholine (spc) and phosphatidic acid (pa) had reduced toxicity and an enhanced antifungal activity in experimental aspergillosis in balb/c mice. incorporation of cholesterol into liposomes led to a dose dependent decrease in the toxicity of hamycin. the ld50 (mg/kg) of hamycin contained in spc/cholesterol/pa (molar ratio 4:5:1) liposomes was 2.8 whereas that in spc/pa liposomes (molar ratio 9:1) was 0.35. although the free drug had little ... | 1993 | 8514651 |
| construction and pathogenicity of aspergillus fumigatus mutants that do not produce the ribotoxin restrictocin. | aspergillus fumigatus, the most common cause of invasive pulmonary aspergillosis (ipa), produces a potent cytotoxin called restrictocin. to investigate the role of restrictocin in ipa, we have constructed fungal strains in which the res gene has been inactivated by gene disruption. these disruptants lack the specific extracellular ribonucleolytic activity associated with restrictocin, as measured by an in vitro rabbit reticulocyte lysate assay. western blot analysis of one disruptant, using an a ... | 1993 | 7934913 |
| a study of the alkaline proteases secreted by different aspergillus species. | strains from several species of aspergillus were grown in the presence of soluble collagen, and the major secreted proteins present in the culture fluid were examined for proteolytic activity. the possibility of relatedness among the alkaline proteases secreted by aspergillus was studied by probing extracts from the various species with polyclonal antisera raised to the isolated alkaline proteases of a. fumigatus and a. oryzae. the pathogenic species a. flavus, a. terreus and a. nidulans hydroly ... | 1993 | 7935565 |
| amphotericin b refractory aspergillosis after itraconazole: evidence for significant antagonism. | failure of amphotericin b to halt aspergillosis in a patient previously treated with itraconazole raised the question of whether amphotericin b lost its activity as a result of antagonism between the two antifungal drugs. azoles exhaust the target of amphotericin b on the fungal cell membrane. accordingly amphotericin b in vitro lost its activity against six isolates of aspergillus fumigatus after exposure to subfungicidal concentrations of itraconazole. prior treatment of mice with itraconazole ... | 1993 | 7935575 |
| [a case of coexisting allergic aspergillosis of the lungs with branchial candidiasis]. | a case is presented of allergic bronchopulmonary aspergillosis in a 36-year-old man. this disease was accompanied by bronchial candidiasis as the complication after longterm antibiotic therapy administered before the diagnosis was established. diagnostic difficulties and outstanding effects of combined antifungal and corticoid treatment are described. | 1993 | 7900391 |
| production of tremorgenic mycotoxins by isolates of aspergillus fumigatus from sawmills in sweden. | one hundred and six strains of a. fumigatus were isolated from 21 sawmills in sweden, and 73 of these strains were examined for production of fumitremorgen b and verruculogen (tremorgenic mycotoxins) on yes-medium using thin layer chromatography (tlc). twenty-three strains (32%) were tremorgen producers and 50 strains (68%) were non-producers. tremorgenic mycotoxins were detected in conidia of seven a. fumigatus strains. the amount of toxin varied between 0.6-8.0 microgram/10(8) conidia (mean va ... | 1993 | 8008045 |
| humoral immunoresponse of pigeons to aspergillus fumigatus antigens. | the aim of this study was to develop an immunological model of avian aspergillosis by studying the humoral response of pigeons to aspergillus fumigatus antigens. immunization was performed by administering weekly injections of a. fumigatus extracts for 70 days (10 weeks). a new booster injection was given 270 days (9 months) following the last immunization. results showed an early aspergillus-specific humoral immunoresponse which reached a maximum level at 42-63 days (6-9 weeks) post-immunizatio ... | 1993 | 8022463 |
| invasive aspergillosis--a rabbit model. | an invasive aspergillosis model in rabbits was attempted using 3 concentrations of a. fumigatus conidia. conidia concentrations of 1 x 10(6), 1 x 10(7) and 1 x 10(8) were inoculated intravenously into rabbits. the severity of infection was directly proportional to the inoculum size of the conidia. aspergillus fumigatus was isolated from livers, kidneys, spleens, hearts and lungs of infected rabbits at a rate of 82%, 75%, 57%, 54% and 32% respectively. cultures of urine specimens taken by bladder ... | 1993 | 8065172 |
| virulence of alkaline protease-deficient mutants of aspergillus fumigatus. | the gene encoding the secreted alkaline protease, a suspected virulence factor of aspergillus fumigatus, was inactivated by gene disruption. the disruption was performed by transformation of a pathogenic strain of the fungus with a linear dna fragment carrying the gene from which the central part was replaced by the selectable escherichia coli hygromycin b dominant resistance marker. two transformants were shown to produce no alkaline protease. restriction fragment analysis of the dna of these t ... | 1993 | 8095038 |
| development of dna probes for fingerprinting aspergillus fumigatus. | several different dna fragments containing nonribosomal repetitive sequences have been isolated from the genome of aspergillus fumigatus and tested as potential dna fingerprinting probes. eight of these clones generate 19 or more bands when hybridized to ecori-digested dna of a reference strain in southern blots, and they fall into four families. individual clones from two families were tested and were found to generate complex southern blot hybridization patterns which are stable within a singl ... | 1993 | 8100242 |
| efficacy of intravenous itraconazole against experimental pulmonary aspergillosis. | the efficacy of intravenous itraconazole solubilized in hydroxypropyl-beta-cyclodextrin was assessed in a rat model of aspergillus fumigatus pneumonia. immunosuppressed rats were infected by intratracheal inoculation of a. fumigatus conidia. intravenous administration of various doses of itraconazole was started immediately after infection and continued once a day for 7 days. a 10-mg dose of intravenous itraconazole per kg was as effective on survival as 1 mg of amphotericin b per kg daily (a su ... | 1993 | 8109952 |
| typing by immunoblot of aspergillus fumigatus from nosocomial infections. | forty-four isolates of aspergillus fumigatus from patients with nosocomial aspergillosis and their hospital environment were collected and typed by immunoblot. laser densitometric analysis of the profiles and homology studies within each case were performed which established relationships between patient and environmental types and showed that patients are often contaminated by several types of a. fumigatus, not all necessarily responsible for the mycosis. one of the cases appeared to be a typic ... | 1993 | 8114802 |

| characterization of the 1,3-beta-glucan synthase of aspergillus fumigatus. | 1,3-beta-glucan synthase activity has been detected in a membrane fraction extracted from the mycelium of the filamentous fungus aspergillus fumigatus. the enzyme was solubilized by chaps and stabilized by filtration on a bio-gel p30 column. highest activity was obtained in the early exponential phase of growth. four factors--gtp, naf, sucrose and edta--added during the extraction procedure, were essential for optimal 1,3-beta-glucan synthase activity. the soluble enzyme preparation was photolab ... | 1993 | 8126434 |
| in-vitro activity of the new triazole d0870 compared with amphotericin b and itraconazole against aspergillus spp. | the in-vitro activity of d0870, a new triazole, was compared with amphotericin b (amp b) and itraconazole (itz) against 40 aspergillus isolates, which included 25 isolates of aspergillus fumigatus, using a broth macro-dilution method at 37 degrees c. minimum inhibitory concentration (mic) and minimum fungicidal concentration (mfc) (killing of > or = 98%) were measured. for 40 isolates, geometric mean (gm) mic values and ranges were d0870 10.55 and 2-32, itz 2.26 and 0.5-64, amp b 2.42 and 1-64 m ... | 1993 | 8144422 |
| crossed immunoelectrophoresis of fungal antigens in tissues as a means of diagnosing systemic aspergillosis and zygomycosis in cattle. | a novel method for diagnosing bovine aspergillosis and zygomycosis is described. rabbit hyperimmune antisera raised against somatic antigens of aspergillus fumigatus and absidia corymbifera were used in crossed immunoelectrophoresis with supernatants from disintegrated tissues from acute necrohaemorrhagic mycotic lesions from cattle. the method specifically identified 4 of 5 lesions with aspergillosis and 2 of 5 lesions with zygomycosis. one lesion dually infected with aspergillosis and zygomyco ... | 1993 | 8146952 |
| enhancement of oxidative response and damage caused by human neutrophils to aspergillus fumigatus hyphae by granulocyte colony-stimulating factor and gamma interferon. | invasive aspergillosis is a serious fungal infection caused by the proliferation and invasion of aspergillus hyphae in tissue. neutrophils (pmns) are the most important line of defense against aspergillus hyphae. to investigate the role of granulocyte colony-stimulating factor (g-csf) and gamma interferon (ifn-gamma) against aspergillus fumigatus, we studied the effects of the two cytokines on the oxidative burst and the capacity of normal human pmns to damage hyphae of the organism. g-csf enhan ... | 1993 | 7681040 |
| [pathologico-anatomic and mycotoxicologic studies of aspergillosis in birds]. | 4.0% of all birds (n = 11249) examined post mortem at the institute of avian diseases, oberschleissheim, showed fungal infections of the respiratory tract. clinical and histopathological findings to date have suggested toxin production in aspergillus fumigatus infections. to obtain detailed information, preselected tissues from the lungs and air sacs (n = 17) were examined by culture and fluorescence microscopy. in 12 cases gliotoxin (0.1-0.45 mg/kg) was found in the a. fumigatus infected tissue ... | 1993 | 7683826 |
| prevention of corticosteroid-induced suppression of human polymorphonuclear leukocyte-induced damage of aspergillus fumigatus hyphae by granulocyte colony-stimulating factor and gamma interferon. | neutrophils (pmns) are a critical line of defense against aspergillus fumigatus infection. increased frequency of invasive aspergillosis has been observed in patients receiving corticosteroids, suggesting a deleterious effect of these compounds on pmn antifungal function. to investigate this hypothesis and to determine the potential preventive utility of granulocyte colony-stimulating factor (g-csf) and gamma interferon (ifn-gamma), the effects of hydrocortisone (hcs) and dexamethasone (dxs) on ... | 1993 | 7691757 |
| effect of administration of diethylcarbamazine with and without fluconazole on experimental fungal infections in mice. | other researchers have found that diethylcarbamazine (dec) is effective treatment for filariasis despite a lack of demonstrated in vitro antifilarial activity. the results of our previous investigations using feline and murine leukemia virus models encouraged us to investigate the use of dec with other infections. in our current experiments, dec treatment was associated with lower brain fungal burden in fluconazole-treated mice following intravenous injection of aspergillus fumigatus or increasi ... | 1993 | 18611537 |
| metabolism of p-cresol by the fungus aspergillus fumigatus. | the fungus aspergillus fumigatus atcc 28282 was shown to grow on p-cresol as its sole source of carbon and energy. a pathway for metabolism of this compound was proposed. this has protocatechuate as the ring-fission substrate with cleavage and metabolism by an ortho-fission pathway. the protocatechuate was formed by two alternative routes, either by initial attack on the methyl group, which is oxidized to carboxyl, followed by ring-hydroxylation, or by ring-hydroxylation as the first step with s ... | 1993 | 16348913 |
| production of xylanases byaspergillus fumigatus andaspergillus oryzae on xylan-based media. | aspergillus fumigatus anda. oryzae were cultivated in laboratory fermenters on media containing xylan as the main carbon source.a. fumigatus produced xylanase on unsubstituted, insoluble beech xylan but growth and enzyme production on soluble xylo-oligosaccharides from the steaming of hardwood were poor due to the presence of inhibitors. an essential prerequisite for good xylanase production bya. fumigatus was decrease in the ph of the cultivation below 3.0 at higher ph values, the production of ... | 1993 | 24419846 |
| effects of antifungal agent combinations administered simultaneously and sequentially against aspergillus fumigatus. | the in vitro effects of antifungal agent combinations administered simultaneously and sequentially against 15 strains of aspergillus fumigatus were tested by the yeast-malt broth method. the synergistic effect of the combination of amphotericin b (amph) and miconazole was observed in nine strains (60%). however, the combinations of amph and fluconazole, amph and ketoconazole, and amph and itraconazole administered simultaneously showed antagonistic effects against three (20%), five (34%), and fo ... | 1994 | 7695271 |
| new in vitro assay based on glucose consumption for determining intraconazole and amphotericin b activities against aspergillus fumigatus. | we developed a new in vitro method of evaluating antifungal molecules. fungal growth was determined by measuring glucose consumption, the only carbon source in a synthetic medium. first, the growth of 12 aspergillus fumigatus strains was studied. glucose consumption was an excellent indicator of fungal growth. second, the partial inhibition of growth was calculated in terms of the 90% or 50% inhibitory concentration for the 12 strains after treatment with itraconazole and amphotericin b. with a ... | 1994 | 7695274 |
| in vitro and ex vivo effects of cyclosporin a on phagocytic host defenses against aspergillus fumigatus. | because cyclosporin a (csa) is extensively used as an immunosuppressive agent, its effects on phagocytic defenses against aspergillus fumigatus were studied in vitro and ex vivo. after incubation with 10 to 250 ng of csa per ml at 37 degrees c for 60 min, polymorphonuclear leukocytes (pmns) exhibited unaltered superoxide anion (o2-) production in response to phorbol myristate acetate and n-formylmethionyl leucyl phenylalanine, whereas > or = 500 ng/ml significantly suppressed it (p < 0.01). more ... | 1994 | 7695277 |
| adjuvant itraconazole in the treatment of destructive sphenoid aspergillosis. | paranasal aspergillosis is a potentially progressive continuum of disease, classically described as having four forms: allergic, non-invasive, invasive, and fulminant. the first two have been considered together as extramucosal disease whilst the latter two are both variants of tissue-invasive disease. sphenoid aspergillosis, given its anatomical location is a more aggressive disease than that found affecting the other paranasal sinuses, even when non-invasive, and may be fatal. this is compound ... | 1994 | 7701229 |
| cloning and disruption of the gene encoding an extracellular metalloprotease of aspergillus fumigatus. | aspergillus fumigatus secretes a serine alkaline protease (alp) and a metalloprotease (mep) when the fungus is cultivated in the presence of collagen as sole nitrogen and carbon source. the gene encoding alp was isolated and characterized previously. we report here the cloning and the sequencing of the gene encoding mep. genomic and cdna clones were isolated from a. fumigatus libraries using synthetic oligonucleotides as probes. stretches of the deduced amino acid sequence were found to be in ag ... | 1994 | 7715453 |
| diagnosis and management of allergic bronchopulmonary aspergillosis. | early diagnosis and treatment is essential for patients afflicted with bronchopulmonary aspergillosis (abpa). inflammatory damage to the airways may be significantly reduced through use of corticosteroids. without treatment, bronchiectasis causing permanent anatomic alteration of the airways may occur. abpa should be considered in any asthmatic who requires oral corticosteroids and has recurrent pulmonary infiltrates. evaluation should include determination of total serum ige, which generally ex ... | 1994 | 7721084 |

| [pleuropulmonary aspergillosis with defective neutrophil functions--g-csf effects on neutrophil functions]. | a 66-year-old man was admitted to our hospital with productive cough and fever. chest x-ray films showed pleural thickening of the right apex and calcification of the lung field. antibiotic therapy was administered but no improvement was obtained. chest ct scan revealed pleural thickening with effusion in the right apex. needle aspiration biopsy was performed and aspergillus fumigatus was isolated from pleural fluid. we began pleural drainage and intrapleural infusion of miconazole, with systemi ... | 1994 | 7509423 |
| in vivo immunosuppressive activity of gliotoxin, a metabolite produced by human pathogenic fungi. | aspergillosis is a disease caused by the opportunistic pathogen aspergillus fumigatus and other related fungi. it occurs mainly in immunosuppressed people and causes very high mortality rates. a fumigatus and other pathogenic fungi have been shown to produce a metabolite, gliotoxin, which has immunosuppressive properties in vitro, but little is known about its in vivo activity. here we report that gliotoxin has increased toxicity in mice after irradiation. a single injection of gliotoxin delayed ... | 1994 | 7510665 |
| postoperative fungal arteritis mimicking vasospasm--case report. | intracranial arteritis due to fungal infection is an uncommon complication of neurosurgical operations. a 36-year-old female developed arteritis caused by aspergillus fumigatus at the site of the temporary clip following the clipping of an initially uncomplicated intracranial aneurysm. the inflammatory, slowly progressing vascular occlusion mimicked the vasospasm common in subarachnoid hemorrhage. | 1994 | 7519756 |
| gliotoxin inhibits transformation and its cytotoxic to turkey peripheral blood lymphocytes. | gliotoxin, an epipolythiodioxopiperizine mycotoxin, has been shown to be produced by, among other fungi, aspergillus fumigatus fresenius. this organism is the major causative agent of the respiratory disease aspergillosis in avian species, especially turkeys. because gliotoxin has been shown to be immunosuppressive and has the potential for being involved in the pathogenesis of aspergillosis, the in vitro activity of this compound with avian lymphocytes was investigated. immunosuppression was in ... | 1994 | 7520534 |
| inhibition of fungal growth by pseudomonas aeruginosa and pseudomonas cepacia isolated from patients with cystic fibrosis. | this study was undertaken because of the infrequency of infections due to candida species in patients with cystic fibrosis despite their extensive treatment with broad-spectrum antibiotics. in vitro susceptibility studies revealed significant inhibition of 11 strains of fungi known to infect human beings by 10 strains of pseudomonas aeruginosa and nine strains of pseudomonas cepacia isolated from the sputum of patients with cystic fibrosis. the fungi were candida krusei, candida keyfr, candida g ... | 1994 | 7522262 |

| fungal polysaccharides. | fungal polysaccharides are cell wall components which may act as antigens or as structural substrates. as antigens, the role of mannans in saccharomyces cerevisiae and candida albicans, and of glycoproteins in aspergillus fumigatus are discussed. analyses on beta-glucan synthetase in paracoccidioides brasiliensis and the inhibitory effect of hansenula mrakii killer toxin on beta-glucan biosynthesis are also considered. | 1994 | 7536840 |
| pyripyropenes, novel inhibitors of acyl-coa:cholesterol acyltransferase produced by aspergillus fumigatus. i. production, isolation, and biological properties. | aspergillus fumigatus fo-1289, a soil isolate, was found to produce a series of novel inhibitors of acyl-coa:cholesterol acyltransferase (acat). four active compounds, named pyripyropenes a, b, c and d, were isolated from the fermentation broth of the producing strain by solvent extraction, silica gel column chromatography, ods column chromatography and preparative hplc. pyripyropenes a, b, c and d show very potent acat inhibitory activity in an enzyme assay system using rat liver microsomes wit ... | 1994 | 8150709 |
| pyripyropenes, novel inhibitors of acyl-coa:cholesterol acyltransferase produced by aspergillus fumigatus. ii. structure elucidation of pyripyropenes a, b, c and d. | the structures of pyripyropenes a, b, c and d, novel acyl-coa:cholesterol acyltransferase (acat) inhibitors, were determined mainly by spectroscopic studies including various nmr measurements. pyripyropenes have a common structure which consists of pyridine, alpha-pyrone and sesquiterpene moieties. one of the three o-acetyl residues in the sesquiterpene moiety of pyripyropene a is replaced with an o-propionyl residue in pyripyropenes b, c and d. | 1994 | 8150710 |
| suppression of fungal growth exhibited by pseudomonas aeruginosa. | three surgery patients were monitored postoperatively, with particular reference to lung infection. in each case there was a clinical impression that pseudomonas aeruginosa suppressed the growth of candida albicans in patients with clinically significant lung infections from whom both of these organisms were isolated from serial sputum samples. regrowth of c. albicans after p. aeruginosa eradication occurred in two patients, despite fluconazole therapy, to which both c. albicans isolates were su ... | 1994 | 8150966 |
| use of dna moderately repetitive sequence to type aspergillus fumigatus isolates from aspergilloma patients. | polymorphism of forty-seven sequential clinical isolates from 3 patients with an aspergilloma was analyzed. dna from each isolate was digested with ecori and hybridized in southern blots with a 32p-labeled nonribosomal dna repetitive sequence. most isolates from each patient displayed the same hybridization pattern. southern blot patterns obtained with dna repetitive sequences can be used to type clinical isolates of aspergillus fumigatus and have shown that aspergilloma patients are most probab ... | 1994 | 8158052 |
| sternal osteomyelitis due to aspergillus fumigatus after cardiac surgery. | sternal osteomyelitis due to aspergillus fumigatus after cardiac surgery occurred in two nonimmunosuppressed patients. the clinical features of the infection were markedly different in the two cases. in the first patient, sepsis showed a late and insidious onset followed by slow progression. in the second case, fungi were isolated from wound swabs within a few days of surgery and the clinical picture showed acute onset and rapid progression. only a few cases of sternal osteomyelitis due to asper ... | 1994 | 8162769 |
| immunologic significance of a collagen-derived culture filtrate containing proteolytic activity in aspergillus-related diseases. | despite increasing evidence implicating fungal proteases in the virulence of pulmonary fungal diseases, routine fungal culture media do not favor protease production. hence, filtrates that serve as the source of antigen for serologic determinations are poor in proteases, and consequently, the immunologic significance of these enzymes is unknown. | 1994 | 8163786 |
| disseminated aspergillosis in a patient with cystic fibrosis and allergic bronchopulmonary aspergillosis. | allergic bronchopulmonary aspergillosis (abpa) is a well-known complication of cystic fibrosis (cf), with an estimated incidence of up to 11%. in patients with cf, the diagnosis of abpa must be based on significant elevation of aspergillus fumigatus (af) antibody and total serum ige, since it is common to already have other clinical and laboratory features of abpa (laufer et al., j allergy clin immunol. 1984; 73:44-48). once abpa is identified in a patient, institution of corticosteroids is stan ... | 1994 | 8165040 |
