O-specific polysaccharide of Proteus penneri strain 41 was studied using 1H- and 13C-NMR spectroscopy, including two-dimensional COSY, heteronuclear 13C,1H-correlation (HETCOR) and one-dimensional NOE spectroscopy, and the following structure of a non-stoichiometrically O-acetylated hexasaccharide repeating unit was established:[structure: see text] where RGlcNAc is 2-acetamido-4-O-[(S)-1-carboxyethyl]-2-deoxyglucose. Cross-reactivity of anti-P. penneri 41 O-serum with other P. penneri strains is discussed, and a new, separate O62 serogroup is proposed which is the next Proteus O-serogroup containing P. penneri strains only.

Some Human Anti-Glycan Antibodies Lack the Ability to Activate the Complement System.

Naturally occurring human antibodies against glycans recognize and quickly eliminate infectious bacteria, viruses and aberrantly glycosylated neoplastic malignant cells, and they often initiate processes that involve the complement system. Using a printed glycan array (PGA) containing 605 glycoligands (oligo- and polysaccharides, glycopeptides), we examined which of the glycan-binding antibodies are able to activate the complement system. Using this PGA, the specificities of antibodies of the IgM and IgG classes were determined in the blood serum of healthy donors (suggested as mostly natural), and, then, using the same array, it was determined which types of the bound immunoglobulins were also showing C3 deposition.

serovar Rissen ( Rissen) is an emerging causative agent of foodborne diseases. The current emergence of antibiotic resistance makes necessary alternative therapeutic strategies. In this study, we investigated the potential of a phage-resistant strain of Rissen (R) as a tool for developing an effective lipopolysaccharide (LPS)-based vaccine.

The Burkholderia cepacia complex (Bcc) is a group of phenotypically similar but genotypically diverse Gram-negative bacteria that pose a significant threat to public health worldwide. Due to the absence of effective therapies, the development of an effective vaccine against Bcc infection is urgently needed. Lipopolysaccharide (LPS) O-antigens of B.

Evolution of the highly successful and multidrug resistant clone ST111 in Pseudomonas aeruginosa involves serotype switching from O-antigen O4 to O12. How expression of a different O-antigen serotype alters pathogen physiology to enable global dissemination of this high-risk clone-type is not understood. Here, we engineered isogenic laboratory and clinical P.
