A new site-specific endonuclease, Sfi I, has been isolated from Streptomyces fimbriatus . This is the first report of a type II restriction endonuclease whose recognition specificity requires eight nucleotides. Sfi I cleaves the sequence, GGCCNNNN / NGGCC , symmetrically...

Food and patient isolates from an Escherichia coli O157:H7 outbreak associated with undercooked ground beef were characterized by pulsed-field gel electrophoresis and Shiga-like toxin genotype. Pulsed-field gel electrophoresis confirmed the epidemiologically implicated source of the two-state outbreak and differentiated between...

Helicobacter pylori is a Gram-negative bacterium that colonizes human stomach and causes gastric inflammation. The species is naturally competent and displays remarkable diversity. The presence of a large number of restriction-modification (R-M) systems in this bacterium creates a barrier against...
