OBJECTIVE To establish a gene identification method of Yersinia pestis and Yersinia pseudotuberculosis for plague surveillance. METHODS According to the specific genomic sequences of Y. pestis and Y. pseudotuberculosis, i.e. "pestis Island (PeI)" and "pseudotuberculosis Island (PsI)" and the published genomic sequences of 12 strains of Y. pestis and 4 strains of Y. pseudotuberculosis, the specific identification primers of these sequences were designed. RESULTS A total of 52 strains of Y. pestis and 57 strains of Y. pseudotuberculosis and other intestinal bacteria strains were tested with PCR. Of the 5 pairs of Y. pestis identification primers, PeI2 and PeI11 were specific for Y. pestis. Besides Y. pestis, the primers PeI1, PeI3 and PeI12 could detect part of 57 Y. pseudotuberculosis strains. Of the 5 pairs of Y. pseudotuberculosis identification primers, PsI1 could detect all the 52 strains of Y. pestis and 57 strains of Y. pseudotuberculosis. PsI7, PsI16, PsI18 and PsI19 were specific for Y. pseudotuberculosis. CONCLUSIONS The primers PsI1, PeI 2 and PeI11, PsI7, PsI16, PsI18 and PsI19 can be used in the rapid identification of Y. pestis and Y. pseudotuberculosis, which can be also used to explore the circulation of atypical Y. pestis in quiescent plague foci.

UI MeSH Term Description Entries
D010930 Plague An acute infectious disease caused by YERSINIA PESTIS that affects humans, wild rodents, and their ectoparasites. This condition persists due to its firm entrenchment in sylvatic rodent-flea ecosystems throughout the world. Bubonic plague is the most common form. Bubonic Plague,Meningeal Plague,Pneumonic Plague,Pulmonic Plague,Black Death,Black Plague,Septicemic Plague,Yersinia pestis Infection
D011159 Population Surveillance Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy. Surveillance, Population

D015011 Yersinia pseudotuberculosis A human and animal pathogen causing mesenteric lymphadenitis, diarrhea, and bacteremia.
D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
