To study the genetic characteristics of DT104 strains of Salmonella Typhimurium and the prevalence of Salmonella Genomic Island (SGI1) in Hungary, 140 recent Salmonella strains of food and animal origin were examined. For the first time in Hungary, the SGI1 was found in 17 out of 59 S. Typhimurium isolates (all proven to be DT104 phage type). These 17 strains were then subtyped by pulsed-field gel electrophoresis (PFGE) into 6 pulsotypes which were less correlated with the geographic origin than with the animal species of origin.
为研究鼠伤寒沙门氏菌DT104菌株的遗传特性以及沙门氏菌基因组岛（SGI1）在匈牙利的流行情况，对140株近期来自食品和动物的沙门氏菌菌株进行了检测。在匈牙利，首次在59株鼠伤寒沙门氏菌分离株（均被证明为DT104噬菌体型）中的17株中发现了SGI1。然后，通过脉冲场凝胶电泳（PFGE）将这17株菌株进一步分为6个脉冲型，这些脉冲型与地理来源的相关性低于与动物来源物种的相关性。
