Swine Salmonella isolates (n=674) from various locations throughout the United States and Canada were analyzed via pulsed-field gel electrophoresis (PFGE) with XbaI. PFGE subtypes were analyzed by cluster analysis and compared to conventional serotyping results. The analysis showed a correlation of serotype to PFGE subtype. In addition, conserved fragments were identified within the restriction patterns that were unique to each serotype. PFGE using XbaI restriction provided a possible alternative method for screening and identifying swine Salmonella serotypes.
对来自美国和加拿大各地的674株猪源沙门氏菌分离株,采用XbaI进行脉冲场凝胶电泳(PFGE)分析。通过聚类分析对PFGE亚型进行分析,并与传统血清分型结果进行比较。分析表明血清型与PFGE亚型之间存在相关性。此外,在每种血清型特有的限制性酶切图谱中鉴定出了保守片段。使用XbaI酶切的PFGE为猪源沙门氏菌血清型的筛选和鉴定提供了一种可能的替代方法。
