Epidemic typhoid in vietnam: molecular typing of multiple-antibiotic-resistant Salmonella enterica serotype typhi from four outbreaks

Abstract

Multidrug-resistant Salmonella enterica serotype Typhi isolates from four outbreaks of typhoid fever in southern Vietnam between 1993 and 1997 were compared. Pulsed-field gel electrophoresis, bacteriophage and plasmid typing, and antibiotic susceptibilities showed that independent outbreaks of multidrug-resistant typhoid fever in southern Vietnam are caused by single bacterial strains. However, different outbreaks do not derive from the clonal expansion of a single multidrug-resistant serotype Typhi strain.

PFGE (BlnI cleavage) patterns of representative isolates from each of the four typhoid outbreaks in southern Vietnam. Bacteriophage lambda concatemer molecular size markers (M; indicated by dashes with sizes of DNA fragments) are indicated to the left of each panel. KG isolates, from left to right, are KG 9, KG 24, KG 27, KG 57, KG 66, and KG 108. CB isolates, from left to right, are CT 1, CT 4, CT 5, CT 38, CT 47, CT 48, CT 53, and CT 88. TT isolates, from left to right, are CT 51, CT 64, CT 86, CT 90, CT 91, CT 92, CT 102, and CT 105. D6 isolates, from left to right, are 14076, 14113, 14222, 14231, 14132, 14182, and 14285.
