title: Spread of a Salmonella typhimurium clone resistant to expanded-spectrum cephalosporins in three European countries.
abstract: Twelve Salmonella typhimurium strains resistant to broad-spectrum cephalosporins were isolated from cases of gastroenteritis during 1996 to 1998 in Russia, Hungary, and Greece. Resistance was due to the production of CTX-M-type extended-spectrum beta-lactamases encoded by similar 12-kb plasmids. By pulsed-field gel electrophoresis, all strains shared the same chromosomal type. These data suggest that an S. typhimurium clone resistant to broad-spectrum cephalosporins is present in at least three European countries.
