Integron-associated antibiotic resistance in Salmonella enterica serovar typhi from Asia

Antimicrob Agents Chemother. 2003 Apr;47(4):1427-9. doi: 10.1128/AAC.47.4.1427-1429.2003.

Abstract

Eighteen of 25 isolates of Salmonella enterica serovar Typhi were multidrug resistant and contained class 1 integrons with a single cassette, dfrVII or aadA1. The dfrVII-containing integron was likely borne on an IncHI1 plasmid. Salmonella serovar Typhi could become resistant to broad-spectrum cephalosporins by integrating cassettes, such as veb-1, a common cassette in Asia.
