Detection and characterization of variant Salmonella genomic island 1s from Salmonella Derby isolates.
The purpose of this study is to investigate the distribution and structure of Salmonella genomic island 1 (SGI1) among Salmonella enterica serovar Derby isolates from swine and their rearing environment. Three variants of SGI1s, specifically SGI1-A, C, and I, were identified by PCR mapping. The results of macro-restriction analysis and DNA sequencing of SGI1 flanking regions revealed that there are at least two genomic lineages of Derby strains bearing SGI1s.
