BACKGROUND In most African countries, indigents treated at public health centres are supposed to be exempted from user fees. In Africa, most of the available knowledge has to do with targeting processes in rural areas, and little is known about how to select the worst-off in an urban area. In rural communities of Burkina Faso, trials of participatory community-based selection of indigents have ...
Leguminous plants and bacteria from the family Rhizobiaceae form a symbiotic relationship, which culminates in novel plant structures called root nodules. The indeterminate symbiosis that forms between Sinorhizobium meliloti and alfalfa requires biosynthesis of Nod factor, a beta-1,4-linked lipochitooligosaccharide that contains an essential 6-O-sulfate modification. S. meliloti also produces s...
Mesorhizobium loti strain NZP2037 was isolated in 1961 in Palmerston North, New Zealand from a Lotus divaricatus root nodule. Compared to most other M. loti strains, it has a broad host range and is one of very few M. loti strains able to form effective nodules on the agriculturally important legume Lotus pedunculatus. NZP2037 is an aerobic, Gram negative, non-spore-forming rod. This report rev...
Characterization of Nitric Oxide-Inducing Lipid A Derived from Mesorhizobium loti Lipopolysaccharide
Mesorhizobium loti is a member of the rhizobia and forms nitrogen-fixing symbioses with several Lotus species. Recently, it was reported that M. loti bacterial cells and their lipopolysaccharide (LPS) preparations transiently induced nitric oxide (NO) production in the roots of L. japonicus. We subsequently found that polysaccharides and the lipid A moiety were responsible for this NO induction...
Stemphylium loti, a pathogen of a cyanogenic plant, possesses a cyanide-insensitive alternate respiratory pathway. In the absence of cytochrome inhibitors, the alternate system had only a minor role in respiration. When S. loti was grown in medium amended with antimycin to block the cytochrome chain, the alternate system accounted for the total oxygen consumption associated with respiration.The...
