| studies on the toxin of aspergillus fumigatus. vii. purification and some properities of hemolytic toxin (asp-hemolysin) from culture filtrates and mycelia. | a hemolytic toxin has been obtained from mycelia and culture filtrates of aspergillus fumigatus by the procedures that included precipitation with ammonium sulfate, chromatography of deae-sephadex, affinity chromatography on concanavalin a-sepharose and gell filtration on sephadex g-50, g-100 and g-150. the purified homolytic toxin was homogeneous on immunological and disk electrophoretic analysis, and the toxin from culture filtrates was identical with that from mycelia by the immunodiffusion t ... | 1977 | 16196 |
| phosphate uptake and involvement of binding protein in tween-80 supplemented culture of aspergillus fumigatus. | tween-80 supplementation in submerged culture of aspergillus fumigatus resulted in an increase of phosphate uptake. the uptake system was characterized as saturable, energy-dependent and operating against the concentration gradient. control and tween 80 cultures showed similar km values for phosphate uptake (50 micrometer). cold osmotic shock treatment of the cultures was found to cause considerable reduction in the ability to take up phosphorus with concomitant release of the binding protein in ... | 1977 | 18385 |
| [process of fumigatin and spinulosin formation by aspergillus fumigatus fres and polarographic assay of these toxins (author's transl)]. | a strain of aspergillus fumigatus (fresenius) isolated from a milk food for calves was grown on a culture medium containing added saccharose. the purpose was to study the synthesis of two recently discovered mycotoxins, fumigatin and spinulosin. the work was performed under many different conditions of temperature, ph and inoculum. these mycotoxins were measured by analytical differential pulse polarography. correlations were observed between the growth rate of a. fumigatus and variation in ph o ... | 1978 | 31124 |
| primary interaction between antibody and components of alternaria. i. immunology and chemical characteristics of labeled antigens. | components were isolated from alternaria tenuis and its culture filtrate, and were radiolabeled with 123-i. the labeled antigenic components had a high polysaccharide content as determined by staining patterns following electrophoresis in polyacrylamide gels and by inactivation with sodium metaperiodate. a primary binding test was employed to detect and measure serum antibodies to the components from a. tennuis. this procedure was more sensitive in detecting antibodies that bound to antigens tha ... | 1975 | 48526 |
| glycoprotein enzymes secreted by aspergillus fumigatus: purification and properties of a second beta-glucosidase. | a second extracellular beta-glucosidase (betalarge) of aspergillus fumigatus was purified to homogeneity and shown to be a glycoprotein, as determined by polyacrylamide gel electrophoresis followed by staining for protein and for carbohydrate. its molecular weight was approximately 340,000 by gel filtration, while sodium dodecyl sulfate-polyacrylamide gel electrophoresis gave an apparent molecular weight of 170,000, suggesting that the enzyme has two subunits. the glucosidase contained covalentl ... | 1975 | 51848 |
| serological investigations in 15 cases of bird fanciers disease. | serological studies in 15 patients with bird fanciers disease are reported. quantitative analysis of serum proteins showed elevation of igg in almost every case. high ige was observed in three patients with isolated asthmatic reactions. in four patients alpha1-antitrypsin was transiently diminished. two of these had heterozygous deficiency of this protein (genotype ms and mz). precipitins against avian sera and avian droppings were found in all patients, but also in some exposed and nonexposed c ... | 1976 | 55391 |

| characterization of antigens from aspergillus fumigatus. i. preparation of antigens from organisms grown in completely synthetic medium. | aspergillus fumigatus was found to grow well in completely synthetic asparagine glycerol medium. four-day-old mycelia were totally disrupted by vigorous mechanical shaking with 0.45-micrometer glass beads. such mechanically produced extracts contained at least 52 precipitating antigens. the number of protein and carbohydrate components was maximal in 4-day-old organisms and decreased in older cultures. conversely, the number of components in culture filtrates increased with longer incubation per ... | 1978 | 101103 |
| characterization of antigens from aspergillus fumigatus. ii. fractionation and electrophoretic, immunologic, and biologic activity. | mycelial extracts of aspergillus fumigatus grown in completely synthetic medium were fractionated by precipitation with ammonium sulfate, by ion-exchange chromatography, and by gel filtration. the fractions were characterized chemically, by analytic polyacrylamide gel electrophoresis, and by tests for serologic and biologic activity. the distribution of the antigens in the fractions was determined by double diffusion in gel and fused-rocket immunoelectrophoresis. activity greater than that of th ... | 1978 | 101104 |
| determination of the minimal inhibitory concentration of amphotericin b and miconazole for 21 strains of aspergillus. | the susceptibility of 21 strains of aspergillus (11 of a. fumigatus, 8 of a, niger, and 2 of a. flavus) isolated from human pathologic specimens to amphotericin b and miconazole has been comparatively studied. determination of the minimal inhibitory concentration of both drugs in a liquid medium showed a noticeably variability for the different strains. the values obtained for amphotericin b varied between 0.25 microgram/ml (2 strains) and 1.25 microgram/ml (5 strains) after 48 hours, and betwee ... | 1978 | 104180 |
| invasive aspergillosis in acute leukemia: correlation with nose cultures and antibiotic use. | aspergillosis in cancer patients is a problem. because not all patients can undergo invasive procedures, we sought other methods for diagnosis. we reviewed the data from all patients with acute nonlymphocytic leukemia treated at our center during a 3-year period. of 125 patients, 18 had invasive aspergillosis (cases). eleven patients had nose cultures growing aspergillus flavus or a. fumigatus; 10 of these 11 had aspergillosis, whereas only eight of 114 without such nose cultures had invasive di ... | 1979 | 105657 |
| filtering hospital air decreases aspergillus spore counts. | we performed counts of airborne spores in a hospital with filtered air where a decrease in nosocomial infection with aspergillus organisms had been documented. for comparison, similar studies were performed at a nearby general hospital in a ward with open windows. the total spore count inside the hospital with filtered air was significantly less than inside the ward with open windows. the total count of aspergillus organisms in the filtered air was significantly less than that in the room with o ... | 1979 | 109022 |
| enzyme linked immunosorbent assay (elisa) for igg and ige antibodies to protein and polysaccharide antigens of aspergillus fumigatus. | elisa has emerged as a useful alternative to other more costly and complex tests. polystyrene microhaemagglutination plates have been used as solid phase to absorb aspergillus fumigatus protein and polysaccharide components for detection of specific antibodies in patients with various forms of pulmonary aspergillosis. igg and ige antibodies to the polysaccharide as well as the protein allergens have been found. for the ige test a double antibody technique has been developed, which is more sensit ... | 1979 | 113131 |
| the presence of precipitating antibodies in the sera of horses with chronic obstructive pulmonary disease (copd). | the sera of horses affected and not affected with chronic obstructive pulmonary disease (copd) were examined for precipitins to micropolyspora faeni and aspergillus fumigatus. precipitins to both antigens were not restricted to copd cases but occurred more frequently in animals affected with copd. many animals without detectable precipitins responded clinically to inhalation challenge with these antigens. | 1979 | 114387 |
| [electron microscopic aspects of opportunistic fungi after pretreatment]. | the ultrastructive of aspergillus fumigatus, aspergillus flavus and aspergillus niger was studied when treated in vitro with 0.001, 0.01 and 0.1% econazole nitrate and econazole base. the very first morphological alterations appear faster than in normal-growing fungus and consist in a convoluted cytoplasmic membrane, large mesosomes and lomasomes and an extensive vacuolization. acid phosphatase is found in the mesosomes and lomasomes and also in the center of the vacuoles. this is an early sign ... | 1979 | 114432 |
| [saphrophytic life of opportunistic fungi]. | probably all pathogenic fungi can cause opportunistic infections in compromised hosts. this paper briefly reviews our knowledge on the saprophytic life - geographic distribution and habitat - of the most common pathogenic fungi. some mycoses are of endogenous origin - e.g. candida albicans is an endosaprophyte - others of epigenon origin - e.g. pityrosporum ovale is an episaprophyte - but most mycoses are caused by fungi which have an exosaprophytic (or exosaprobic) life: one becomes infected af ... | 1979 | 114433 |

| evidence that aspergillus fumigatus growing in the airway of man can be a potent stimulus of specific and nonspecific ige formation. | serum ige levels in patients with allergic bronchopulmonary aspergillosis are elevated but the degree of elevation varies markedly. serum ige levels in patients with aspergillomas may be strikingly elevated or normal. absorption of serums with antigens of aspergillus fumigatus combined with a solid phase radioimmunoassay technic demonstrated that both immunoglobulin e (ige) and immunoglobulin g (igg) antibody activity against a. fumigatus were markedly reduced without a parallel reduction in ser ... | 1977 | 329672 |
| chitin biosynthesis in protoplasts and subcellular fractions of aspergillus fumigatus. | the biosynthesis of chitin has been obtained in broken mycelia and protoplasts of the fungus aspergillus fumigatus. the specific activity of chitin synthase (ec 2.4.1.16) in a membrane preparation from protoplasts derived from the hyphal tips of a. fumigatus was 26.8-fold greater than that of the chitin synthase in broken mycelia, indicating that the active chitin synthase is located primarily in a membrane-bound site at the hyphal tip. polyoxin d was a potent competitive inhibitor of the enzyme ... | 1977 | 329836 |

| the effect of freezing and the influence of isolation medium on the recovery of pathogenic fungi from sputum. | the primary objective of this study was to determine whether freezing sputa in dry ice had any effect on the recovery of pathogenic fungi. sputa seeded with each of five fungi (histoplasma capsulatum, blastomyces dermatitidis, cryptococus neoformans, coccidioides immitis, and aspergillus fumigatus) were frozen and stored for 24, 48, and 72 hours on dry ice. h. capsulatum was killed, and only a few colonies of b. dermatitidis and c. neoformans were isolated from these sputa. however, a. fumigatus ... | 1977 | 335251 |
| safety evaluation of aspergillus fumigatus grown on cassava for use as an animal feed. | a safety evaluation of aspergillus fumigatus i21, grown in a cassava carbohydrate and salts medium, was undertaken. male weanling rats were fed the fungus at 20, 30 and 40% of the diet for 90 days. a control group was given soybean oil meal as the sole source of protein. weekly determinations of the body weights and feed consumptions were made. a few days prior to termination of the feeding study, a kidney function test was undertaken on the rats. at the end of the feeding period hematology, blo ... | 1977 | 336162 |
| effect of phosphate on ergot alkaloid synthesis in aspergillus fumigatus. | high concentration of inorganic phosphate in the culture medium of aspergillus fumigatus inhibited ergot alkaloid synthesis. addition of l-tryptophan but not mevalonate or 5-methyltryptophan to the above culture restored the alkaloid synthesis to the level found in normal cultures. the decrease in alkaloid synthesis in the fungus accompanies an increase in cell mass, cellular protein and sterol content. aspartate aminotransferase and alanine aminotransferase activities were significantly increas ... | 1977 | 336488 |
