使用片段分析，PCR和Southern杂交，我们发现，沙门氏菌肠道血清型猪霍乱窝藏各种大小的毒力质粒，而血清型鼠伤寒，肠杆菌，和都柏林携带一个独特的大小的质粒。此外，鼠伤寒毒力质粒所含基因的顺序与其他三种质粒中检测到的顺序相同，均含有缺失。
Using fragment profiling, PCR, and Southern hybridization, we found that Salmonella enterica serovar Choleraesuis harbored virulence plasmids of various sizes, whereas serovars Typhimurium, Enteritidis, and Dublin carried a plasmid of a unique size. Also, the virulence plasmid of Typhimurium contained genes in the same order detected in the other three plasmids, all of which contained deletions.
