Cryptococcus flavescens, a strain originally identified as C. laurentii, was isolated from the cerebrospinal fluid of an AIDS patient, and the soluble capsular polysaccharide of the yeast was investigated. Glucuronoxylomannan (GXM) was obtained from C. flavescens under conditions similar to those used to obtain C. neoformans polysaccharide. However, the GXM differed from C. neoformans polysaccharide in the decreased O-acetyl group content. The structure of GXM was determined by methylation analysis, partial acid hydrolysis, NMR analyses, and controlled Smith degradation. These analyses indicated that GXM has the following structure: an alpha-(1-->3)-D-mannan backbone with side chains of beta-D-glucuronic acid residues bound to the C-2 position of the mannose residue. The C-6 position of the mannose is substituted with D-man-beta-(1-->4)-D-xyl-beta-(1--> disaccharide. Furthermore, the existence of side chains containing more than two xylose residues was suggested. This mannosylxylose side chain is a novel structure in polysaccharides of C. neoformans and other Cryptococcus species. 相似文献

Summary Conditions of growth are described which lead to the formation of a dense capsule aboutCellulomonas flavigena and provide data which suggest that, although accumulated as an extracellular structure, it may function as an energy reserve. The capsule is formed when the bacteria are cultured in a minimal medium containing an excess of one of several carbohydrates. The bacterial cells which are encapsulated are also densely aggregated. The capsule is not formed and the cells are not aggregated when the bacteria are cultured in complex growth media. The transfer of aggregated cells to a medium devoid of carbon and energy source results in disappearance of the capsule and disaggregation of the cells. 相似文献

A rhamnose, galactose and pyruvic acid containing polysaccharide (capsule) together with the peptidoglycan was isolated fromRhodopseudomonas capsulata St. Louis as the insoluble sediment after sodium dodecyl sulfate extraction of cell envelope fractions. Treatment with pronase E separated the soluble polysaccharide from the insoluble peptidoglycan. After lysozyme-digestion, both the capsule polysaccharide and peptidoglycan were soluble.The capsule was also accumulated in the combined interphase/phenol-phase of hot phenol-water extracts of whole cells. Again, the capsule and peptidoglycan were sedimented together as long as no pronase E-treatment was performed. With the phage-resistant mutant (R. capsulata St. Louis RC1-), no capsule polysaccharide was obtained in the combined interphase/phenol phase.An acidic polysaccharide (slime) different from the capsule in composition and serology was obtained by Cetavlon fractionation of hot phenol/water extracts of cells of both the wild-type and the mutant cells. It was shown to consist mainly of rhamnose, glucosamine and galacturonic acid.The use of O/K-antisera and of capsule polysaccharideantisera allowed a separate visualization of the capsule and slime layers.This paper is dedicated to Professor Hans G. Schoegel on the occasion of his 60th birthday 相似文献

Abstract Protein profile and capsular material thickness of Streptococcus suis serotype 2 strains were compared after in vitro and in vivo growth. Three virulent and one avirulent strains were used. These strains were grown in Brain Heart Infusion (BHI) broth, cells were collected by centrifugation, resuspended in a sterile saline solution and injected in diffusion chambers. The devices were then inserted in rat abdomens for 17 h. In vitro grown strains were also inoculated into fresh BHI broth and cultivated for 17 h at 37°C. In vivo as well as in vitro grown bacteria were harvested by centrifugation, processed in a French pressure cell, treated with lysozyme and centrifuged to collect cell proteins for SDS-PAGE analysis. Transmission electron microscopy using polycationic ferritin labeling to stabilize capsular material was also carried out. No significant modification was noted in the protein profile for any strain after in vivo growth except for a 39 kDa protein of one virulent strain. On the other hand, an increase in thickness of capsular material was noted for the three in vivo grown virulent strains while no change was noted for the avirulent strain. This increase in capsular material thickness of virulent strains was accompanied by an increased resistance to killing by pig polymorphonuclear leukocytes. The capacity to produce more capsular material in vivo seems to be an attribute of some virulent S. suis serotype 2 strains. 相似文献

Seed micromorphology in 22 species, capsule surface in 28 species and capsule hairs in 20 species of genus Verbascum distributed in Iran were studied using scanning electron microscopy. The seed surface is ridged or alveolate among the studied species. Depth and density of the alveoli or ridges, size of polygonal cells along with arrangement of vesicles on the walls separating the polygonal cells on the seed surface seem to be species-specific in Verbascum. The capsule surface is striate, distinctly or indistinctly, or even smooth in Verbascum. The capsules are rarely glabrous (in V. orientale and V. intricatum), densely covered by branched hairs, or loosely by glandular hairs, depending on species. From the results of this study it is obvious that no correlation exists between the studied species concerning the micromorphological aspects studied here. 相似文献
