Abstract

The process of subtyping is important epidemiologically for recognizing outbreaks of infection. Pulsedfield gel electrophoresis (PFGE) is considered the “gold standard” of molecular typing methods and a method of seperating large DNA molecules. In our study, Electrophoresis of DNA digested with the restriction endonuclease Xba I, Xho I and Smi I produced fragment profiles. Digestion of genomic DNA with Xba I and Xho I provided results that not distinguished among field strains of Brucella abortus which tested in study. But Smi I restriction enzyme resulted in two PFGE pattern consisting of 13-15 bands that ranged in size from 33 to 668 standard marker. Analysing DNA fingeprinting software, cluster analysis showed 93.75% similar in two PFGE pattern.
