We developed a multiplex one-step quantitative reverse transcription-PCR (qRT-PCR) assay for detection of OPV Sabin strains 1, 2, and 3 directly in stool samples with an external control to normalize samples for viral quantity and compared its performance with that of viral culture. We applied the assay to samples from infants in Dhaka, Bangladesh, after the administration of trivalent OPV (tOPV) at weeks 14 and 52 of life (on days 0 [pre-OPV], +4, +11, +18, and +25 relative to vaccination). When 1,350 stool samples were tested, the sensitivity and specificity of the quantitative PCR (qPCR) assay were 89 and 91% compared with culture. A quantitative relationship between culture\n            <jats:sup>+<\/jats:sup>\n            \/qPCR\n            <jats:sup>+<\/jats:sup>\n            and culture\n            <jats:sup>\u2212<\/jats:sup>\n            \/qPCR\n            <jats:sup>+<\/jats:sup>\n            stool samples was observed. The kinetics of shedding revealed by qPCR and culture were similar. qPCR quantitative cutoffs based on the day +11 or +18 stool samples could be used to identify the culture-positive shedders, as well as the long-duration or high-frequency shedders. Interestingly, qPCR revealed that a small minority (7%) of infants contributed the vast majority (93 to 100%) of the total estimated viral excretion across all subtypes at each time point. This qPCR assay for OPV can simply and quantitatively detect all three Sabin strains directly in stool samples to approximate shedding both qualitatively and quantitatively.\n          <\/jats:p>","DOI":"10.1128\/jcm.02406-14","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T08:20:55Z","timestamp":1415348455000},"page":"206-211","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":14,"title":["Kinetics of Poliovirus Shedding following Oral Vaccination as Measured by Quantitative Reverse Transcription-PCR versus Culture"],"prefix":"10.1128","volume":"53","author":[{"given":"Mami","family":"Taniuchi","sequence":"first","affiliation":[{"name":"Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia, Charlottesville, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sharmin","family":"Begum","sequence":"additional","affiliation":[{"name":"Centre for Vaccine Science and Parasitology Lab, International Centre for Diarrhoeal Disease Research, Bangladesh, Dhaka, Bangladesh"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Md Jashim","family":"Uddin","sequence":"additional","affiliation":[{"name":"Centre for Vaccine Science and Parasitology Lab, International Centre for Diarrhoeal Disease Research, Bangladesh, Dhaka, Bangladesh"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James A.","family":"Platts-Mills","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia, Charlottesville, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Liu","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia, Charlottesville, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beth D.","family":"Kirkpatrick","sequence":"additional","affiliation":[{"name":"Department of Medicine (Infectious Diseases), University of Vermont College of Medicine, Burlington, Vermont, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anwarul H.","family":"Chowdhury","sequence":"additional","affiliation":[{"name":"National Polio and Measles Laboratory, Institute of Public Health, Dhaka, Bangladesh"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khondoker M.","family":"Jamil","sequence":"additional","affiliation":[{"name":"National Polio and Measles Laboratory, Institute of Public Health, Dhaka, Bangladesh"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rashidul","family":"Haque","sequence":"additional","affiliation":[{"name":"Centre for Vaccine Science and Parasitology Lab, International Centre for Diarrhoeal Disease Research, Bangladesh, Dhaka, Bangladesh"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"William A.","family":"Petri","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia, Charlottesville, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric R.","family":"Houpt","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia, Charlottesville, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.micro.58.030603.123625"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/risa.12031"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2013.11.056"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.ppat.1002599"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1086\/605331"},{"key":"e_1_3_3_7_2","volume-title":"Polio laboratory manual","author":"World Health Organization","year":"2004","unstructured":"World Health Organization. 2004.
