In Gram-negative bacteria, which include some of the most devastating human pathogens, just two mechanisms for the export of polysaccharides have been identified so far. Now a Max Planck research team ...

Most of the carbon fixed by plants through photosynthesis is ultimately stored in the cell wall, primarily in the form of polysaccharides such as cellulose, xylan, and glucomannan. Yet how plants ...

Pneumococcal polysaccharide conjugate vaccines prevent pneumococcal disease in infants, but their efficacy against pneumococcal community-acquired pneumonia in adults 65 years of age or older is ...

In early 2000, a protein–polysaccharide conjugate vaccine targeting seven pneumococcal serotypes was licensed in the United States for use in young children. We examined population-based data from the ...

Marine microbial communities are responsible for processing an estimated half of the organic carbon annually produced in the ocean (Azam and Malfatti, 2007). It is generally assumed that the ...
