| [changes in the membrane atpase activity of erythrocytes and candida guilliermondii under the action of roseofungin]. | changes in the mg-atpase and na, k-atpase activity of the rat erythrocyte and candida guilliermondii membranes under the effect of roseofungin were studied. the antibiotic was totally bound to the isolated plasmatic membranes of candida guilliermondii, up to 3 micrograms of the antibiotic per 1 microgram of the yeast protein. the mg-aptase activity of these membranes was slightly inhibited by the antibiotic. the activity of na, k-atpase was almost completely inhibited even at 0.04 mg of roseofun ... | 1980 | 6255858 |
| impaired neutrophil function and myeloperoxidase deficiency in pregnancy. | the ability of neutrophils to phagocytose and kill candida guilliermondii was investigated in 28 pregnant women and compared wtih 29 healthy controls. phagocytosis was normal, but the ability to kill and digest candida was reduced to 65% of normal. quantitative myeloperoxidase measurement revealed a considerable reduction of this enzyme (55% of normal) while neutrophil alkaline phosphatase levels were nearly twice as high as in normals. it is suggested that both lack of myeloperoxidase and impai ... | 1980 | 6246914 |
| selective interaction of a fucus vesiculosus lectin-like mucopolysaccharide with several candida species. | a complex carbohydrate specific lectin-like mucopolysaccharide extracted from the brown alga fucus vesiculosus was found to agglutinate candida guilliermondii cells but not those of other species of the same genus (except for a weak agglutination with c. krusei). the selective binding of this mucopolysaccharide correspondingly affected the growth of the yeasts. the results suggest that there are notable differences--at least with respect to the receptors for the f. vesiculosus mucopolysaccharide ... | 1983 | 6223551 |

| [genetic control of riboflavin biosynthesis in pichia guilliermondii yeasts. the detection of a new regulator gene rib81]. | the properties of mutants resistant to 7-methyl-8-trifluoromethyl-10-(1'-d-ribityl)-isoalloxazine (mtry) were studied. the mutants were isolated from a genetic line of pichia guilliermondii. several of them were riboflavin overproducers and had derepressed flavinogenesis enzymes (gtp cyclohydrolase, 6.7-dimethyl-8-ribityllumazine synthase) in iron-rich medium. an additional derepression of these enzymes as well as derepression of riboflavin synthase occurred in iron-deficient medium. the charact ... | 1985 | 3838729 |
| biosynthesis of riboflavin. an aliphatic intermediate in the formation of 6,7-dimethyl-8-ribityllumazine from pentose phosphate. | 6,7-dimethyl-8-ribityllumazine synthase deficient mutants of candida guilliermondii were divided into two groups on the basis of in vitro complementation. mutants of complementation group i produce an intermediate x from ribose 5-phosphate in a reaction requiring mg++ ions. compound x was partially purified and was shown to be a phosphoric acid ester. 6,7-dimethyl-8-ribityllumazine can be formed from compound x by cell extracts from mutants of complementation group ii. the reaction requires 5-am ... | 1985 | 3838473 |
| [the nature of the pyrimidine substrate of 6,7-dimethyl-8-ribityllumazine synthase participating in riboflavin biosynthesis in yeasts]. | 2,4-dihydroxy-5-amino-6-ribitylaminopyrimidine and 2,4-dihydroxy-5-amino-6-ribitylaminopyrimidine-5'-phosphate are studied for their effect on the activity of 6,7-dimethyl-8-ribityllumazine synthase of pichia guilliermondii yeasts. it is shown that when nonphosphorylated form of pyrimidine and ribose-5-phosphate (donor c-4--a fragment) is used as a substrate, the specific activity of 6,7-dimethyl-8-ribityllumazine synthase is high and be2+ and f- ions, inhibitors of alkaline phosphatases, do not ... | 1987 | 3810894 |
| candida delta-aminovalerate: alpha-ketoglutarate aminotransferase: purification and enzymologic properties. | a new enzyme that catalyzes the transamination of delta-aminovalerate with alpha-ketoglutarate was purified to homogeneity from adapted cells of candida guilliermondii var. membranaefaciens. the relative molecular mass determined by gel filtration was estimated to be close to 118,000. the transaminase behaved as a dimer with two similar subunits in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. the enzyme has a maximum activity in the ph range of 7.8-8.5 and at 40 degrees c. alpha-ke ... | 1986 | 3778871 |
| [study of the resistance of candida guilliermondii to polyene antibiotics]. | 250 candida guilliermondii strains resistant to the polyene antibiotics nystatin, levorin and amphotericin b were obtained using uv irradiation. when the mutant strains became resistant to one of the polyene antibiotics, their resistance to the other ones changed. phenotypic analysis showed that the resistance of the strains to polyene antibiotics did not make them susceptible to a rise in osmotic pressure and to a change of the temperature of incubation. some of the polyene-resistant strains we ... | 1986 | 3773794 |
| a method for measuring rate of neutrophil phagocytosis of staphylococcus epidermidis or candida guilliermondii using uptake of tritiated uridine. | a method is described for measuring the rate of neutrophil phagocytosis, together with the total and intracellular kill at 20 min of 2 different organisms. the technique is sensitive over the early stages of phagocytosis as it distinguishes between adherent and engulfed organisms and is totally objective. it therefore allows detection of defects in phagocytosis which are missed if only the end point is assessed. both total and intracellular killing are measured under the same conditions as those ... | 1986 | 3772117 |
| 4-aminobutyrate:2-oxoglutarate aminotransferase from candida. purification and properties. | an enzyme which catalyzes the transamination of 4-aminobutyrate with 2-oxoglutarate was purified 588-fold to homogeneity from candida guilliermondii var. membranaefaciens, grown with 4-aminobutyrate as sole source of nitrogen. an apparent relative molecular mass of 107,000 was estimated by gel filtration. the enzyme was found to be a dimer made up of two subunits identical in molecular mass (mr 55,000). the enzyme has a maximum activity in the ph range 7.8-8.0 and a temperature optimum of 45 deg ... | 1986 | 3699025 |
| [biochemical functions of rib5 and rib6 gene products participating in riboflavin biosynthesis in the yeast pichia guilliermondii]. | the biosynthesis of riboflavin precursor 6,7-dimethyl-8-ribityllumazine was studied in extracts of pichia guilliermondii yeast mutants of rib5 and rib6 genotypes with impaired synthesis of proteins p1 and p2, respectively. it was shown that synthesis of 6,7-dimethyl-8-ribityllumazine took place in extracts of rib5 mutant (active p1 protein) in the presence of 2,4-dihydroxy-5-amino-6-ribitylaminopyrimidine and the compound formed from ribose-5-phosphate by extracts of rib6 mutant (active p2 prote ... | 1987 | 3692155 |
| effect of dialysate fluids on phagocytosis and killing by normal neutrophils. | inadequate host defenses may partly explain the problem of recurrent peritonitis in patients on continuous ambulatory peritoneal dialysis. it has been suggested that these defenses may be adversely affected by the fluids used for dialysis, and so we examined the effects of unused, effluent, and infected peritoneal dialysis fluids on phagocytosis and killing by normal neutrophils. we used a clinical isolate of staphylococcus epidermidis as the test organism, as this organism is the most commonly ... | 1987 | 3624441 |
| candida l-norleucine,leucine:2-oxoglutarate aminotransferase. purification and properties. | a new enzyme which catalyzes the transamination of l-norleucine (2-aminohexanoic acid) and l-leucine with 2-oxoglutarate was purified to homogeneity from cells of candida guilliermondii var. membranaefaciens. the relative molecular mass determined by gel filtration was estimated to be close to 100,000. the transaminase behaved as a dimer which consists of two subunits identical in molecular mass (mr 51,000). the enzyme has a maximum activity in the ph range of 8.0-8.5 and at 55 degrees c. 2-oxog ... | 1987 | 3622507 |
| [effect of 2-amino-2-thiazoline on the level of lipid peroxidation products in different yeast species]. | the influence of 2-amino-2-thiazoline on lipid peroxidation in yeasts saccharomyces cerevisiae and pichia guilliermondii has been studied in vivo and in vitro. in the case the radioresistance of diploid yeasts-saccharomycetes is changed the radioprotector can produce a direct effect on lipid peroxidation. different radioprotective efficiency of the preparation with regard to different strains of one and the same yeast culture is explained by its different influence on the content of endogenous r ... | 1987 | 3554317 |
| [transformation of hansenula polymorpha, pichia guilliermondii, williopsis saturnus yeasts by a plasmid carrying the ade2 gene of saccharomyces cerevisiae]. | red adenine-dependent mutants of hansenula polymorpha, pichia guilliermondii, williopsis saturnus yeasts have been transformed by the plasmid pye (ade2) 2 dna containing ade2 gene from saccharomyces cerevisiae. the analysis of two p. guilliermondii ade+-transformants has revealed the integration of pye (ade2)2 sequence into the recipient strain genome and partial restoration of the deficient function. | 1986 | 3543662 |
| [sorption of microorganisms by fiber materials]. | candida guilliermondii and escherichia coli cells were adsorbed on glass and basalt fibres with a similar specific surface, but with a different charge. the quantity of adsorbed microorganisms did not depend on the type and charge of a fibre surface. however, cells were adsorbed faster and more firmly on positively charged and uncharged fibres than on negatively charged fibres. | 1986 | 3534527 |
| effect of feverfew on phagocytosis and killing of candida guilliermondii by neutrophils. | the in vitro effect of the herbal remedy feverfew on neutrophil function was examined. it was shown that addition of feverfew extract inhibited phagocytosis of candida guilliermondii and its overall killing. however, intracellular killing was not affected, suggesting that the apparent defect in total killing merely reflected the failure of uptake. the implications for the in vivo effects of feverfew are discussed. | 1988 | 3366482 |
| neutrophil function in patients on continuous ambulatory peritoneal dialysis. | frequent and recurrent episodes of peritonitis are a major cause of morbidity in patients on continuous ambulatory peritoneal dialysis (capd). one factor contributing to this problem may be an abnormality of neutrophil function in these patients. we have therefore quantified phagocytosis and killing by circulating and peritoneal neutrophils from patients on capd with and without peritonitis. circulating neutrophils from uninfected patients showed reduced phagocytosis of both staphylococcus epide ... | 1988 | 3355789 |
| inter- and intra-species crosses between candida albicans and candida guilliermondii. | hybridization was shown to occur both between strains of the imperfect diploid yeast candida albicans and between c. albicans and the distantly related haploid yeast candida (pichia) guilliermondii. prototrophic hybrids were selected from crosses of multiply marked auxotrophic mutants of the two species. in most cases, mild ultraviolet irradiation of the c. albicans partner was required. examination of auxotrophic markers in segregants from the hybrids indicated that recombination, rather than h ... | 1986 | 3334695 |

| candida guilliermondii var. guilliermondii infection in infertile women. | the sera of 263 women--217 infertile and 46 pregnant--were examined by various serological methods (precipitation test, agglutination, indirect immunofluorescence) to detect candida guilliermondii var. guilliermondii (c.g.) infection. the precipitation reaction was performed with extracellular c. guilliermondii antigen, the agglutination reaction was employed parallel with c. albicans. in the infertile group 122 (56.2%) proved to be c.g. positive, while in the fertile 11 women (23.9%) proved to ... | 1989 | 2691888 |
| immunologic significance of diverse specificity of monoclonal antibodies against mannans of candida albicans. | two agglutinating igm mab against mannan ag of candida albicans strains were investigated for their specificity. the agglutinating patterns of both mab with a panel of stationary phase of yeast cells of standard strains did not match those of any known polyclonal antibody (pab) factors. the reactive patterns of both mab for a given panel of 202 isolates of seven candida species and the mode of competitive binding between mab and a pab factor, as determined by a combination of direct and indirect ... | 1989 | 2681415 |
| production of riboflavin (vitamin b2) by hydrocarbon-utilizing yeasts. | candida guilliermondii wickerham was found to be superior to the other yeasts tested for growth yields and riboflavin production when cultivated on different carbohydrate and hydrocarbon-containing media. among the refined petroleum fractions and cheap hydrocarbons tested, solar was selected as a carbon source best suited for the fermentation process. the highest growth yield and riboflavin output (10.64 mg/100 ml) by c. guilliermondii wickerham were achieved by placing aliquots of 20 ml medium ... | 1989 | 2679769 |
| differentiation of candida guilliermondii varieties by lectin-like substances from marine algae. | lectin-like substances of 54 marine algae, corresponding to 30 red algae and 24 brown algae, were studied to estimate the agglutination activity against candida guilliermondii. extracts of dictyopteris membranacea, bifurcaria bifurcata, halidrys siliquosa, ascophyllum nodosum, fucus serratus and f. spiralis algae showed selective agglutinating activities for c. guilliermondii "sensu stricto" and some of its varieties. according to their response to agglutination (positive or negative), certain a ... | 1989 | 2616890 |
| [antifungal activity of 6-acetamido-2-alkylthiobenzothiasoles in vitro]. | the antifungal activity of 6-acetamido-2-alkylthiobenzothiazoles (altogether 13 derivatives) against aspergillus niger, candida guilliermondii and against the yeast-like and mycelial forms of candida albicans was determined. no efficacy of more significance was found against a. niger. 6-acetamido-2-n-butylthiobenzothiazole, which with the ed50 = 23 micrograms/ml ranks among the agents of medium efficacy, was most effective against c. guilliermondii. good efficacy was found in 6-acetamido-2-n-pen ... | 1989 | 2611910 |
