Clustering Analysis of Salmonella enterica Serovar Typhi Isolates in Korea by PFGE, Ribotyping, and Phage Typing

摘要: Abstract Salmonella enterica serovar Typhi is a Gram-negative bacterium causing the acute febrile disease typhoid fever. In Korea from 2004 to 2006, total of 51 isolates were identified in stool and blood healthy carriers patients with or without overseas travel histories. this study, antibiogram, pulsed-field gel electrophoresis (PFGE), automated ribotyping performed as molecular epidemiological methods phage typing classical subtyping tool isolates. Only two multidrug resistant 82.3% susceptible 16 antimicrobial agents tested. When dendrogram was created based on PFGE results, subtypes could be clustered into five groups by 80% similarity criterion. The patterns 31 (60.8%) belonged Cluster 3, predominant cluster study. Three travel–associated cases differentiated 4 which three nalidixic acid resistant. Major...
