[Shigella; Escherichia coli; Campylobacter; Hybridization, as related to genomics, is the process in which two complementary single-stranded DNA and/or RNA molecules bond together to form a double-stranded molecule. The bonding is dependent on the appropriate base-pairing across the two single-stranded molecules. Hybridization is an important process in various research and clinical This method has many desir-able features including rapid detection, selectivity, and little required instrumentation. DNA hybridization is becoming an important new adjunct to conventional methods for the diagnosis of infectious diseases, inherited conditions, and neoplasia. DNA-DNA hybridization is used to find out the sequence identity between two or more DNA samples. It is used to detect and determine the size of specific DNA fragment in the given mixture of genomes. DNA hybridization provides an extremely powerful tool in molecular biology. DNA hybridization arrays measure simultaneously the expression of several genes. DNA hybridization techniques were used to detect Shigella species, enteroinvasive Escherichia coli, and enterotoxigenic E. coli.

Nucleic acid hybridization with a labeled probe is the only practical way to detect a complementary target sequence in a complex nucleic acid mixture. DNA hybridization involves hybridizing the DNA from two different species based on complementary base pairing. A single strand of DNA from each species is combined and allowed to anneal (recombine), and then it is heated to reach the melting temperature. The first section of this species should have at least 70% DNA homology by hybridization and at most 5% sequence divergence. Start studying DNA Hybridization & Applications. In the former area, DNA microarrays have become a standard tool for gene expression analysis.
