Evaluation of PCR for diagnosis of Bordetella pertussis and Bordetella parapertussis infections.
PCR, using primers Plp1 and Plp2, was evaluated for the detection of DNA from Bordetella pertussis in bacterial strains and in nasopharyngeal samples from patients with a cough lasting at least 7 days. The assay could detect DNA from 6 CFU of B. pertussis/10 microl of sample. Results of the PCR assay were compared with those of cultures, a determination of serum antibodies against pertussis tox...
متن کاملMultiplex real-time PCR assay for detection and differentiation of Bordetella pertussis and Bordetella parapertussis
A triplex real-time PCR assay for detection and differentiation of Bordetella pertussis and Bordetella parapertussis was developed. Three targets were used for amplification in a single tube: the insertion sequence IS481 and the pertussis toxin promoter region (ptxP) for B. pertussis, and the insertion sequence IS1001 for B. parapertussis. The performance of this PCR assay was evaluated in para...
متن کاملReal-time LightCycler PCR for detection and discrimination of Bordetella pertussis and Bordetella parapertussis.
Real-time PCR assays based on the LightCycler technology were developed for individual (simplex PCR) and simultaneous (duplex PCR) detection and discrimination of Bordetella pertussis and Bordetella parapertussis in clinical samples. The assays were evaluated with 113 specimens from patients with and without symptoms of pertussis. Results were compared to those from conventional culture and Taq...
متن کاملmultiplex real-time pcr assay for detection and differentiation of bordetella pertussis and bordetella parapertussis.
background and objective: rapid diagnosis of pertussis is important for the timely isolation of the infection source and early prevention measures among the contact persons, especially among non-vaccinated infants for whom pertussis is life- threatening. materials and methods: targets is481 , is1001, bp0026 and human gapdh gene were used to develop a multiplex real- time pcr assay based on the ...
متن کاملEvaluation of real-time PCR for detection of and discrimination between Bordetella pertussis, Bordetella parapertussis, and Bordetella holmesii for clinical diagnosis.
PCR is increasingly being used as a diagnostic test for the detection of Bordetella pertussis and Bordetella parapertussis DNA, as it has improved sensitivity and specificity in comparison to conventional techniques. The assay described here uses the two insertion sequences IS481 and IS1001 for B. pertussis and B. parapertussis, respectively, with detection by molecular beacons. The real-time P...
