Detection of <i>Helicobacter pylori</i> DNA in Feces and Saliva by Polymerase Chain Reaction: a Review
1 Apr 2004
Abstract excerpt
The polymerase chain reaction (PCR), known for its high sensitivity and specificity, has been used for the detection of Helicobacter pylori DNA in bodily materials such as feces and saliva. Since fecal specimens contain PCR inhibitors, DNA before PCR amplification has been purified using various biochemical, immunological and physical pre-PCR steps. Several PCR protocols, differing from each other in the...
