title: Characterization of extended-spectrum-beta-lactamase (CTX-M-15)-producing strains of Salmonella enterica isolated in France and Senegal.
abstract: Three clinical isolates of Salmonella enterica recovered between 2000 and 2003 in France and Senegal were found to produce extended-spectrum beta-lactamase CTX-M-15. The two isolates from Senegal were recovered from stool of a hospitalized patient with gastroenteritis in 2000 and from an urine specimen of an out-patient with urinary tract infection in 2001. These S. enterica isolates belonged to serotype Kentucky and were clonally related as determined by pulsed-field gel electrophoresis and automated ribotyping. The third isolate of serotype Typhimurium was recovered from a patient hospitalized in France for an acute gastroenteritis acquired in Lebanon. The bla(CTX-M-15) gene was located on two different transferable plasmids, one of which also carried bla(TEM-1), bla(OXA-30), aminoglycoside-, tetracycline-, and sulfamethoxazole-trimethoprim resistance genes. ISEcp1 element was found to be located upstream of bla(CTX-M-15) in the same position as reported previously in CTX-M-15-producing Escherichia coli from India and Turkey. This is the first report of bla(CTX-M-15) in the genus Salmonella.
