Fourteen morphologically putative populations of X. krugi were clearly separated into four different profiles by RFLP analysis (Alu I and Hinf I), sequencing of the ITS-1 region, and subsequent Maximum Likelihood phylogenetic analyses. These four profiles were further supported by a principal component analysis of morphometric characters that yielded four taxonomic clusters matching those produ...

Restriction fragment length polymorphism analysis after PCR amplification (RFLP-PCR) of the 16S rRNA gene has been previously proposed as a rapid method to identify Aeromonas species. In the present study, the precision of RFLP-PCR was evaluated with 62 Aeromonas reference strains. The analysis revealed that Aeromonas veronii biovar sobria strains produce various patterns, possibly leading to i...

A PCR-restriction fragment length polymorphism (RFLP) analysis method that analyzes a part of the dnaJ gene was designed for the rapid and accurate identification of Staphylococcus spp. XapI or Bsp143I digestion of the PCR-generated products rendered distinctive RFLP patterns that allowed 41 reference species and subspecies to be identified with a high degree of specificity. The novel method wa...

Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) is a technique used to identify single nucleotide polymorphisms (SNPs) based on the recognition of restriction sites by enzymes. RFLP-PCR an easy-to-perform and inexpensive tool for initial analysis SNPs potentially associated with some monogenic diseases, as well in genotyping, genetic mapping, lineage screening, for...

To separate the unknown Streptomyces strains isolated from soil samples, the interspacer regions of 16S-23S rDNA of 14 isolates were amplified with PCR (polymerase chain reaction) and digested with three restriction endonucleases, namely, Bsp143I, HaeIII and MnlI. The restriction patterns were used for RFLP (restriction fragment length polymorphism) analysis. A dendrogram were constructed using...
