INTRODUCTION Prompt diagnosis of candidaemia and invasive candidosis is crucial to the early initiation of antifungal therapy. The poor sensitivity of blood cultures (BCs) has led to the development of fungal glycan tests as a diagnostic adjunct. We analysed the performance of tests for the detection of circulating β-D-1,3-glucan (BDG) and mannan in the intensive care unit (ICU) setting. METH...

This study investigated the effects of dietary supplementation with the prebiotics fructo-oligosaccharide (FOS) and mannan-oligosaccharide (MOS) on the performance, small intestinal microflora, and immune response of broilers. Two hundred forty 1-d-old Ross broiler chickens were randomly assigned to 6 dietary treatment groups: control, avilamycin (6 mg/kg), 0.25% FOS, 0.5% FOS, 0.025% MOS, and ...

We have previously demonstrated the ability of human neutrophil myeloperoxidase to bind to mannan isolated from Candida albicans. Mannan may therefore be a primary component of the yeast cell wall which provides for binding of myeloperoxidase, a requirement potentially important for the candidacidal activity of the enzyme. In this report, we describe experiments to consider the relationship of ...

A soil microorganism, designated Arfhrobacfer GJM-1, has been isolated which is capable of growing on Saccharomyces cerevisiae mannan as the carbon source. When grown on mannan, the microorganism secretes an a-mannosidase into the cultural medium. The enzyme is not found when mannose, glucose, or glycerol is substituted for mannan, but is present when oligosaccharides obtained by acetolysis of ...

The genus Amycolatopsis is a member of the phylogenetic group nocardioform actinomycetes, which also includes the genus Mycobacterium. Members of this group have a characteristic cell envelope structure, dominated by various complex lipids and polysaccharides. Amongst these, lipoglycans are of particular interest since mycobacterial lipoarabinomannans are important immunomodulatory molecules. I...

Dendritic cells (DCs) are APCs that play an essential role by bridging innate and adaptive immunity. DC-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) is one of the major C-type lectins expressed on DCs and exhibits high affinity for nonsialylated Lewis (Le) glycans. Recently, we reported the characterization of oligosaccharide ligands expressed on SW1116, a typical h...

BACKGROUND H1N1 influenza viruses mutate rapidly, rendering vaccines developed in any given year relatively ineffective in subsequent years. Thus it is necessary to generate new vaccines every year, but this is time-consuming and resource-intensive. Should a highly virulent influenza strain capable of human-to-human transmission emerge, these factors will severely limit the number of people tha...
