چکیده
The synthesis of different rhamnomannans in a strain of Sporothrix schenckii (1099.12) was shown by use of 13C nuclear magnetic resonance spectroscopy. Fractionation of a polysaccharide preparation from cells grown at 25 degrees C provided a neutral monorhamnosyl rhamnomannan and an acidic rhamnomannan containing 4-O-substituted glucuronic acid units and also (1 leads to 2)-linked dirhamnosyl side chains.

Synthesis of monorhamnosyl L-rhamno-D-mannans by conidia of Sporothrix schenckii.
A rhamnomannan containing single-unit alpha-L-rhamnopyranose side chains was identified in isolated conidia from Sporothrix schenckii. Such a rhamnomannan differed from the dirhamnosyl rhamnomannan synthesized by the hyphae but was very similar to the monorhamnosyl rhamnomannan formed in yeastlike cells. Nuclear magnetic resonance spectroscopy and chemical analysis were used to compare these po...
متن کاملAnalysis of Cerebrospinal Fluid in Diagnosis of Bacterial Meningitis; Using Nuclear Magnetic Resonance Spectroscopy: A Systematic Review
Background: Analysis of biofluids provides a unique window into the biochemical status of a living organism since the composition of a given biofluid will be modulated according to the level of function of the cells that are intimately concerned with its manufacture and secretion. One of the most successful approaches to biofluid analysis has been the application of NMR spectroscopy. Objective...
متن کاملBRIEF NOTE 18s Ribosomal RNA Gene Sequence Characters Place the Pathogen Sporothrix schenckii in the Genus Ophiosto
BERBEE, M. L., AND TAYLOR, J. W. 1992. 18s ribosomal RNA gene sequence characters place the human pathogen Sporothrix schenckii in the genus Ophiostoma. Experimental Mycology 16, 87-91. Using the sequence of the gene for the 18s subunit of ribosomal RNA, we show that the asexual human pathogen Sporothrix schenckii lies phylogeneticaily within the sexual genus Ophiostoma. By distance or maximum ...
متن کاملMelanins Protect Sporothrix brasiliensis and Sporothrix schenckii from the Antifungal Effects of Terbinafine.
Terbinafine is a recommended therapeutic alternative for patients with sporotrichosis who cannot use itraconazole due to drug interactions or side effects. Melanins are involved in resistance to antifungal drugs and Sporothrix species produce three different types of melanin. Therefore, in this study we evaluated whether Sporothrix melanins impact the efficacy of antifungal drugs. Minimal inhib...

Soil organic matter is the largest source of organic carbon in the soil surface which played an enormous role in restoring balance, environmental sustainability, soil elements and climatic conditions. Organic materials influence physical, chemical and biological properties of soil and thus soil fertility directly and indirectly. The amount, type and composition of organic matter are different i...
