[Hemolysis produced by Candida tropicalis isolates from clinical samples].
INTRODUCTION Yeasts belonging to the genus Candida are responsible for the majority of fungal infections in humans. Candida tropicalis has been one of most commonly isolated non-albicans species. To analyze in vitro hemolysis promoted by clinical isolates of C. tropicalis obtained from blood and other clinical samples from hospitalized patients at the University Hospital of Londrina State Unive...
متن کاملSiderophores and related outer membrane proteins produced by pseudomonads isolated from eels and freshwater.
A total of 46 environmental pseudomonads, together with six type strains, were examined for their siderophore-producing activity. All strains were able to grow under iron-limiting conditions, gave orange halos in the CAS agar assay, and produced hydroxamates, and some of them also produced phenolate-type compounds. Bioassays showed that all strains, except Pseudomonas aeruginosa, promoted growt...
متن کاملStructure and membrane affinity of a suite of amphiphilic siderophores produced by a marine bacterium.
Iron concentrations in the ocean are low enough to limit the growth of marine microorganisms, which raises questions about the molecular mechanisms these organisms use to acquire iron. Marine bacteria have been shown to produce siderophores to facilitate iron(III) uptake. We describe the structures of a suite of amphiphilic siderophores, named the amphibactins, which are produced by a nearshore...
متن کاملIsolation and structural characterization of siderophores, madurastatins, produced by a pathogenic Actinomadura madurae.
Madurastatins Al (1), A2 (2) and A3 (3), novel pentapeptides that were acylated with salicylic acid at the N-terminus, were isolated from the culture broth of a pathogenic Actinomadura madurae IFM 0745 strain. These structures were mainly determined by 2D NMR and MS/MS spectral techniques. The strain produced simultaneously madurastatins B1 (4) and B2 (5) consisting of Ser and salicylic acid mo...
متن کاملSiderophores produced by Magnaporthe grisea in the presence and absence of iron.
An analysis of siderophores produced by Magnaporthe grisea revealed the presence of one intracellular storage siderophore, ferricrocin, and four coprogen derivatives secreted into the medium under iron depletion. Structural analysis showed that the compounds are coprogen, coprogen B, 2-N-methylcoprogen and 2-N-methylcoprogen B. Siderophore production under low and high iron conditions was quant...
