Abstract

<i>Salmonella enterica</i>Serovar Typhi with CTX-M β-Lactamase, Germany

Highlights

The isolated strain was identified as S. enterica ser
PCR and sequence analyses were performed with universal primers for the ESBL genes blaCTX-M, blaTEM, and blaSHV as described previously (2)
In the transconjugant, the blaCTX-M-15 and qnrB2 genes were identified by PCR

Summary

Introduction

To the Editor: Infection with Salmonella enterica serovar Typhi, the causative agent of typhoid fever, is an acute systemic illness with a high proportion of illness and deaths, especially in developing countries. Typhi infections occur among travelers returning from disease-endemic areas. After emergence of multidrug-resistant S. enterica ser. Typhi strains that confer resistance to chloramphenicol, trimethoprim, and ampicillin, quinolones have become the primary drugs for treatment (1). We report the isolation of CTXM–producing S. enterica ser.
