Sugar-Coating Bacteria with Lipopolysaccharides

Lipopolysaccharides in diazotrophic bacteria

Biological nitrogen fixation (BNF) is a process in which the atmospheric nitrogen (N2) is transformed into ammonia (NH3) by a select group of nitrogen-fixing organisms, or diazotrophic bacteria. In order to furnish the biologically useful nitrogen to plants, these bacteria must be in constant molecular communication with their host plants. Some of these molecular plant-microbe interactions are ...

Pneumococcus: the sugar-coated bacteria.

The study of Streptococcus pneumoniae (the pneumococcus) had been a central issue in medicine for many decades until the use of antibiotics became generalized. Many fundamental contributions to the history of microbiology should credit this bacterium: the capsular precipitin reaction, the major role this reaction plays in the development of immunology through the identification of polysaccharid...

Characterization and immunobiologic activities of lipopolysaccharides from periodontal bacteria.

lacterial surface structures play a critical role in the initiation of infectious diseases. Various surface ^ components of pathogenic bacteria have been reported to be involved in host injury. There is a great deal of evidence incriminating certain Gram-negative, anaerobic bacteria present in the gingival crevice as etiologic agents of human periodontal diseases. We have isolated endotoxic cel...
