Rapid detection and identification of Streptococcus ratti by a species-specific PCR method.

To establish a rapid and species-specific detection and identification method of Streptococcus ratti by polymerase chain reaction, two PCR primer pairs specific to S. ratti were designed on the basis of the nucleotide sequence of the dextranase gene (dex) of S. ratti ATCC19645(T).
