The objective of this study was to determine the genetic diversity and virulence factors of Vibrio cholerae and V. parahaemolyticus from selected aquatic environments in Bachok, Kelantan, Malaysia. Out of 50 water samples, 33 were confirmed with the presence of presumptive V. cholerae and V. parahaemolyticus based on biochemical tests. Primers targeting toxR gene specific for V. cholerae (800bp...

Genetic similarities and distances between wild-type olives in Turkey were studied using an RAPD-PCR assay. Seven wild olive tree samples were collected from villages in Manisa and Izmir provinces. Genomic DNA was extracted from young leaves and the RAPD-PCR assay was used to generate RAPD markers. Sixty-five random primers obtained from Operon Technologies were tested for the assay (OP-A 1-20,...

In the present study, RAPD-PCR was used to assess genetic diversity of the rye including landrances and new rye cultivars coming from Central Europe and the Union of Soviet Socialist Republics (SUN). Five arbitrary random primers were used to determine RAPD polymorphism in the set of 38 rye genotypes. These primers amplified altogether 43 different DNA fragments with an average number of 8.6 fr...

OBJECTIVE To review the feasibility of coupling the techniques of random amplified polymorphic DNA (RAPD) with carbon nanotube-based modified electrode for guanine/deoxyguanine triphosphate (dGTP) electrochemical sensing for mapping of the pancreatic cancer genetic fingerprint and screening of genetic alterations. METHODS We developed a new method to study the electrochemical behavior of dGTP...

Random amplification of polymorphic DNA (RAPD) analysis using the polymerase chain reaction proved a useful technique in the biodiversity analysis of microorganisms but may lack reproducibility in the poorly standardized methodology. In the present investigation, the RAPD technique was optimized for characterizing cyanobacterial isolates in order to ensure its reproducibility and discriminatory...

Classification and differentiation of Bacillus anthracis isolates by genetic markers play an important role in anthrax research. We used a PCR based method--Random Amplification of Polymorphic DNA (RAPD)--to identify genetic markers in B. anthracis strains. Twenty-five differential genetic markers were identified which divided the strains into five different groups. Three selected RAPD-markers ...

The usefulness of random amplification of polymorphic DNA (RAPD) analysis for typing Indian strains of M. tuberculosis was investigated. M. tuberculosis H37Rv, M. tuberculosis DT and 42 clinical isolates of M. tuberculosis were subjected to RAPD-PCR using 7 random decamer primers. All 7 primers were found to be differentiated and produced specific RAPD profiles. The polymorphic amplicons served...

We compared the robustness and discriminatory power of the enterobacterial repetitive intergenic consensus (ERIC) and random amplified polymorphic DNA (RAPD) fingerprinting methods for detecting cases of mixed Helicobacter pylori infection in Peruvian shantytown residents. H. pylori isolates from 63 participants were cultured, and five single colonies and a pool of additional colonies from each...
