Non-typical lipopolysaccharide core regions of some Hafnia alvei strains: structural and serological studies

Two Kdo-heptose regions identified in Hafnia alvei 32 lipopolysaccharide: the complete core structure and serological screening of different Hafnia O serotypes.

Hafnia alvei, a gram-negative bacterium, is an opportunistic pathogen associated with mixed hospital infections, bacteremia, septicemia, and respiratory diseases. Various 3-deoxy-d-manno-oct-2-ulosonic acid (Kdo)-containing fragments different from known structures of core oligosaccharides were previously found among fractions obtained by mild acid hydrolysis of some H. alvei lipopolysaccharide...

Two Kdo - heptose regions identified in Hafnia alvei 32 lipopolysaccharide : the 1 complete core structure and serological screening of different Hafnia O - serotypes

Ceftazidime resistance in Hafnia alvei.

Two morphotypes of Hafnia alvei differed in their susceptibilities to beta-lactam antibiotics. Both produced an inducible Bush group 1 beta-lactamase. Hyperinducibility of this enzyme was associated with reduced susceptibility in one morphotype.

Degradation of Phytate by the 6-Phytase from Hafnia alvei: A Combined Structural and Solution Study

Phytases hydrolyse phytate (myo-inositol hexakisphosphate), the principal form of phosphate stored in plant seeds to produce phosphate and lower phosphorylated myo-inositols. They are used extensively in the feed industry, and have been characterised biochemically and structurally with a number of structures in the PDB. They are divided into four distinct families: histidine acid phosphatases (...

Structural analysis of the lipid A isolated from Hafnia alvei 32 and PCM 1192 lipopolysaccharides.

Hafnia alvei, a Gram-negative bacterium, is an opportunistic pathogen associated with mixed hospital infections, bacteremia, septicemia, and respiratory diseases. The majority of clinical symptoms of diseases caused by this bacterium have a lipopolysaccharide (LPS, endotoxin)-related origin. The lipid A structure affects the biological activity of endotoxins predominantly. Thus, the structure o...
