FIG. 1 Proportions that were nalidixic acid resistant (NAR) and multidrug resistant (MDR) among the isolates of S. Typhi. Numbers in brackets indicate the total number of blood culture positive S. Typhi isolates cultured in each year at Jawaharlal Institute of Postgraduate Medical Education and Research and the Government General Hospital, Pondicherry, India.

FIG. 2 Pulsed field gel electrophoresis fingerprinting of 20 S. Typhi isolates that exhibited a range of antimicrobial susceptibility profiles identified in this study. Cluster analysis was performed using the method of dice coefficient with unweighted pair group method with arithmetic mean with band tolerance set to 2.0%. All isolates were cultured from blood. Antimicrobial drugs: ciprofloxacin (CIP), ampicillin (AMP), chloramphenicol (CHL), trimethoprim/sulphamethoxazole (SXT), nalidixic acid (NAL), ceftriaxone (CRO).
