Surveillance of antimicrobial resistance of Salmonella enterica serotype Typhi in seven Asian countries

Two hundred and four Salmonella enterica serotype Typhi (S. Typhi) isolates were collected from seven Asian countries during 2002-2004. Multidrug-resistant S. Typhi (resistant to >= 3 antibiotics) was detected in 84 (41.2 %) isolates and 142 (69.6 %) showed reduced susceptibility to ciprofloxacin (minimum inhibitory concentration=0.125-1.0 mg/l). This study highlights the worsening Situation of antimicrobial resistance of S. Typhi in Asia.
