Influence of lipopolysaccharide chemotype on the interaction between Klebsiella pneumoniae and human polymorphonuclear leucocytes.

abstract：:Using pulsed-field gel electrophoresis (PFGE), nine profile types were identified in XbaI digests of a panel of strains of Salmonella enteritidis phage type 4 (PT 4) isolated in England and Wales between 1967 and 1992.

abstract：:The hypA-E operon is involved in the maturation of all three NiFe hydrogenases in Escherichia coli. Two hyp promoters have been described; a sigma54-dependent promoter upstream of hypA, and a sigma70-dependent promoter (PhypA) within the hypA coding region. Here it is shown that the oxygen-responsive transcription fac...
