Rapid identification of Yersinia enterocolitica in blood by the 5' nuclease PCR assay.

ABSTRACT: Yersinia enterocolitica accounts for 50% of the clinical sepsis episodes caused by the transfusion of contaminated red blood cells. A 5' nuclease TaqMan PCR assay was developed to detect Y. enterocolitica in blood. Primers and a probe based on the nucleotide sequence of the 16S rRNA gene from Y. enterocolitica were designed. Whole-blood samples were spiked with various numbers of Y. enterocolitica cells, and total chromosomal DNA was extracted. When the TaqMan PCR assay was performed, as few as six bacteria spiked in 200 microliter of blood could be detected. The assay was specific and did not detect other Yersinia species. The TaqMan assay is easy to perform, takes 2 h, and has the potential for use in the rapid detection of Y. enterocolitica contamination in stored blood units.

Rapid 5' nuclease (TaqMan) assay for detection of virulent strains of Yersinia enterocolitica.

Project description:We have developed a rapid procedure for the detection of virulent Yersinia enterocolitica in ground pork by combining a previously described PCR with fluorescent dye technologies. The detection method, known as the fluorogenic 5' nuclease assay (TaqMan), produces results by measuring the fluorescence produced during PCR amplification, requiring no post-PCR processing. The specificity of the chromosomal yst gene-based assay was tested with 28 bacterial isolates that included 7 pathogenic and 7 nonpathogenic serotypes of Y. enterocolitica, other species of Yersinia (Y. aldovae, Y. pseudotuberculosis, Y. mollaretti, Y. intermedia, Y. bercovieri, Y. ruckeri, Y. frederiksenii, and Y. kristensenii), and other enteric bacteria (Escherichia, Salmonella, Citrobacter, and Flavobacterium). The assay was 100% specific in identifying the pathogenic strains of Y. enterocolitica. The sensitivity of the assay was found to be >/=10(2) CFU/ml in pure cultures and >/=10(3) CFU/g in spiked ground pork samples. Results of the assay with food enrichments prespiked with Y. enterocolitica serotypes O:3 and O:9 were comparable to standard culture results. Of the 100 field samples (ground pork) tested, 35 were positive for virulent Y. enterocolitica with both 5' nuclease assay and conventional virulence tests. After overnight enrichment the entire assay, including DNA extraction, amplification, and detection, could be completed within 5 h.

Detection of pathogenic Yersinia enterocolitica by a rapid and sensitive duplex PCR assay.

Project description:A duplex PCR assay targeting the ail and 16S rRNA genes of Yersinia enterocolitica was developed to specifically identify pathogenic Y. enterocolitica from pure culture. Validation of the assay was performed with 215 clinical Yersinia strains and 40 strains of other bacterial species. Within an assay time of 4 h, this assay offers a very specific, reliable, and inexpensive alternative to the conventional phenotypic assays used in clinical laboratories to identify pathogenic Y. enterocolitica.

Development of a fluorogenic 5' nuclease PCR assay for detection of the ail gene of pathogenic Yersinia enterocolitica.

Project description:In this report we describe the development and evaluation of a fluorogenic PCR assay for the detection of pathogenic Yersinia enterocolitica. The assay targets the chromosomally encoded attachment and invasion gene, ail. Three primer-probe sets (TM1, TM2, and TM3) amplifying different, yet overlapping, regions of ail were examined for their specificity and sensitivity. All three primer-probe sets were able to detect between 0.25 and 0.5 pg of purified Y. enterocolitica DNA. TM1 identified all 26 Y. enterocolitica strains examined. TM3 was able to detect all strains except one, whereas TM2 was unable to detect 10 of the Y. enterocolitica strains tested. None of the primer-probe sets cross-reacted with any of the 21 non-Y. enterocolitica strains examined. When the TM1 set was utilized, the fluorogenic PCR assay was able to detect </=4 Y. enterocolitica CFU/ml in pure culture and 10 Y. enterocolitica CFU/ml independent of the presence of 10(8) CFU of contaminating bacteria per ml. This set was also capable of detecting </=1 CFU of Y. enterocolitica per g of ground pork or feces after a 24-h enrichment in a Yersinia selective broth.

5' nuclease PCR assay to detect Yersinia pestis.

Project description:The 5' nuclease PCR assay uses a fluorescently labeled oligonucleotide probe (TaqMan) to rapidly detect and quantitate DNA templates in clinical samples. We developed a 5' nuclease PCR assay targeting the plasminogen activator gene (pla) of Yersinia pestis. The assay is species specific, with a detection threshold of 2.1 x 10(5) copies of the pla target or 1.6 pg of total cell DNA. The assay detected Y. pestis in experimentally infected Xenopsylla cheopis fleas and in experimentally infected monkey blood and oropharyngeal swabs. The TaqMan assay is simple to perform and rapid and shows promise as a future field-adaptable technique.

Development of a highly specific assay for rapid identification of pathogenic strains of Yersinia enterocolitica based on PCR amplification of the Yersinia heat-stable enterotoxin gene (yst).

Project description:The chromosomal gene yst, which encodes a heat-stable enterotoxin of Yersinia enterocolitica, is a useful diagnostic marker because it occurs only in invasive strains of this species. A homologous gene also occurs in some strains of Yersinia kristensenii. Sequence analysis of the yst genes from two different strains of Y. enterocolitica and from Y. kristensenii revealed a substantial number of mismatches at the 3' ends of the yst genes of the so-called American and European biotypes of Y. enterocolitica. Moreover, several mismatches and a deletion of 5 codons were found in the yst of Y. kristensenii. These findings were used to develop a PCR-based assay for yst of Y. enterocolitica which yielded a detectable product in as little as 50 min. The assay was 100% specific in terms of its ability to identify potentially pathogenic strains of Y. enterocolitica regardless of biotype or serotype. The PCR yielded an amplicon that was visible on agarose gel electrophoresis from as few as 100 CFU, or 10 CFU when the PCR was combined with dot blot hybridization with a digoxigenin-labeled oligonucleotide probe that corresponded to an internal sequence of yst. These results establish the value of the yst gene as a target for the identification of pathogenic bioserotypes of Y. enterocolitica and the usefulness of PCR for this purpose.

Multiplex PCR method for differentiating highly pathogenic Yersinia enterocolitica and low pathogenic Yersinia enterocolitica, and Yersinia pseudotuberculosis.

Project description:A multiplex PCR method for rapid and sensitive diagnosis, differentiating three pathogenic Yersinia groups such as the highly pathogenic Y. enterocolitica, including serotype O8, low pathogenic Y. enterocolitica, and Y. pseudotuberculosis, was developed. Four primer pairs were chosen to detect the genes fyuA, ail, inv, and virF, responsible for the virulence in pathogenic Yersinia species. Under the multiplex PCR conditions, the unique band patterns for the highly pathogenic Y. enterocolitica, low pathogenic Y. enterocolitica, and Y. pseudotuberculosis were generated from Yersinia strains. The detection limit of this method was 101-103 CFU per reaction tube. This multiplex PCR method could detect highly pathogenic Y. enterocolitica O8 from the wild rodent fecal samples that were culture-positive. Therefore, the new multiplex PCR method developed in this study is a useful tool for rapid and sensitive diagnosis, distinguishing three pathogenic Yersinia groups.

Automated 5' nuclease PCR assay for identification of Salmonella enterica.

Project description:A simple and ready-to-go test based on a 5' nuclease (TaqMan) PCR technique was developed for identification of presumptive Salmonella enterica isolates. The results were compared with those of conventional methods. The TaqMan assay was evaluated for its ability to accurately detect 210 S. enterica isolates, including 100 problematic "rough" isolates. An internal positive control was designed to use the same Salmonella primers for amplification of a spiked nonrelevant template (116 bp) in the sample tube. The PCR test correctly identified all the Salmonella strains by resulting in positive end-point fluorescence (FAM) signals for the samples and positive control (TET) signals (relative sensitivity [DeltaRn], >0. 6). The diagnostic specificity of the method was assessed using 120 non-Salmonella strains, which all resulted in negative FAM signals (DeltaRn, < or =0.5). All 100 rough Salmonella strains tested resulted in positive FAM and TET signals. In addition, it was found that the complete PCR mixture, predispensed in microwell plates, could be stored for up to 3 months at -20 degrees C. Thus, the diagnostic TaqMan assay developed can be a useful and simple alternative method for identification of Salmonella, particularly in large reference laboratories.

Development of a loop-mediated isothermal amplification assay for rapid detection of Yersinia enterocolitica via targeting a conserved locus.

Project description:BACKGROUND AND OBJECTIVES:Loop-mediated isothermal amplification is a novel nucleic acid amplification assay providing as a simple diagnostic tool for rapid identification of microbial diseases in developing countries. In this study, a LAMP assay was established for Yersinia enterocolitica, a leading cause of acute enterocolitis in young children. MATERIALS AND METHODS:LAMP assay was established with four primers targeting a specific locus for the detection of Y. enterocolitica. The assay was conducted at 65°C in thermo block for 90min. The sensitivity of LAMP was evaluated in comparison to conventional PCR using pTZ57R containing the target locus. Finally, specificity was assessed using DNA from common enteropathogenic bacteria. RESULTS:Results showed that the sensitivity of LAMP assay was 44-copy number, which was 10-fold higher than that of PCR. No cross-reactivity was observed when testing against other enteropathogenic pathogens. CONCLUSION:This study showed that LAMP assay is an alternative molecular diagnostic tool for infections with Y. enterocolitica. In addition, this method may be useful in diagnosis at field or in laboratories without PCR machine.
