Increasing Ceftriaxone Resistance in Salmonellae, Taiwan

Abstract

In Taiwan, despite a substantial decline of Salmonella enterica serotype Choleraesuis infections, strains resistant to ciprofl oxacin and ceftriaxone persist. A self-transferable bla CMY-2 -harboring IncI1 plasmid was identified in S. enterica serotypes Choleraesuis, Typhimurium, Agona, and Enteritidis and contributed to the overall increase of ceftriaxone resistance in salmonellae.
