Characterization of an Hfr Strain of Shigella Flexneri.
Schneider, Herman (Walter Reed Army Institute of Research, Washington, D.C.), and Stanley Falkow. Characterization of an Hfr strain of Shigella flexneri. J. Bacteriol. 88:682-689. 1964.-A Hfr Shigella flexneri, strain 69, was obtained by terminal marker selection in a cross between Hfr Escherichia coli and S. flexneri. The chromosome of this Hfr Shigella bears gross homology to the E. coli chro...
متن کاملVaccination against shigellosis with attenuated Shigella flexneri 2a strain SC602.
The Shigella flexneri 2a SC602 vaccine candidate carries deletions of the plasmid-borne virulence gene icsA (mediating intra- and intercellular spread) and the chromosomal locus iuc (encoding aerobactin) (S. Barzu, A. Fontaine, P. J. Sansonetti, and A. Phalipon, Infect. Immun. 64:1190-1196, 1996). Dose selection studies showed that SC602 causes shigellosis in a majority of volunteers when 3 x 1...
متن کاملOverexpression, purification, characterization and preliminary crystallographic study of phosphoglycolate phosphatase from Shigella flexneri 2a strain 301.
Phosphoglycolate phosphatase has a salvage function in the metabolism of the 2-phosphoglycolate formed during bacterial DNA repair. In order to better understand its dimerization behaviour, the influence of metal ions on its activity and its catalytic mechanism at the molecular level, recombinant phosphoglycolate phosphatase from Shigella flexneri was overexpressed, purified, characterized and ...
متن کاملKeratitis due to Shigella flexneri.
Multiresistant Shigella flexneri isolates were cultured from the cornea and stool of a girl. Genetic analysis showed the isolates were identical. Shigella spp. are rare causes of ulcerative keratitis; there have only been 14 published cases since 1943. Although prognosis after local treatment is good, shigellosis is a systemic infection, possibly leading to dehydration.
متن کاملSerological study of the mucinases from Shigella flexneri.
Burnet and Stone (1947) described a mucinsplitting enzyme in cultures of Vibrio comma which causes desquamation of the intestinal mucosa of guinea pigs and have suggested a role for this mucinase in the pathogenesis of Asiatic cholera. While possession of this enzyme may be an important factor in determining the virulence of cholera strains, it is by no means the only attribute, since avirulent...
