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.
本研究的目的是调查猪源肠炎沙门氏菌德比血清型菌株及其饲养环境中沙门氏菌基因组岛1（SGI1）的分布和结构。通过PCR图谱鉴定出SGI1的三种变体，即SGI1-A、C和I。SGI1侧翼区域的宏观限制性分析和DNA测序结果表明，携带SGI1的德比菌株至少有两个基因组谱系。
