Analysis of amino acid sequences of penicillin-binding protein 2 in clinical isolates of Neisseria gonorrhoeae with reduced susceptibility to cefixime and ceftriaxone.

Neisseria gonorrhoeae strains with reduced susceptibility to cefixime and ceftriaxone, with minimum inhibitory concentrations (MICs) of cefixime of 0.125-0.25 microg/ml and ceftriaxone of 0.

Transcriptional analysis of the Escherichia coli mreBCD genes responsible for morphogenesis and chromosome segregation.

The Escherichia coli mreB gene encodes an actin-like cytoskeletal protein and is required for rod shape formation of cells and chromosome segregation. Just downstream of mreB, the mreC and mreD genes are located. They are also required for rod shape formation, though their role in chromosome segregation is unclear.
