Genetic diversity of Gram-negative, proteolytic, psychrotrophic bacteria isolated from refrigerated raw milk
چکیده انگلیسی

The random amplified polymorphic DNA (RAPD) fingerprinting technique was used to assess the genetic diversity of 70 isolates of Gram-negative proteolytic psychrotrophic bacteria that were isolated from refrigerated raw milk. Three oligonucleotides, which generated 87 fragments of polymorphic DNA, were used in the amplification reactions. The genetic distance values calculated using Jaccard's coefficient showed there was high genetic variability among the isolates. Cluster analysis procedures suggested that the genetic variability among isolates belonging to the same species was as high as the variability among different species. Clustering by the UPGMA hierarchical method and data graph dispersion indicated a tendency of the isolates to group according to whether they did or did not ferment glucose.
