Nonetheless, sensitive and affordable methods for active screening of malaria parasites in low-transmission settings remain urgently needed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>We developed a molecular screening method, capture and ligation probe-PCR (CLIP-PCR), which achieved the sensitivity of reverse-transcription PCR but eliminated the reliance on RNA purification and reverse transcription. In this method, 18S rRNA of genus Plasmodium is released from blood, captured onto 96-well plates, and quantified by the amount of ligated probes that bind continuously to it. We first used laboratory-prepared samples to test the method across a range of parasite densities and pool sizes, then applied the method to an active screening of 3358 dried blood spot samples collected from 3 low-endemic areas in China.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Plasmodium falciparum diluted in whole blood lysate could be detected at a concentration as low as 0.01 parasites\/\u03bcL, and a pool size of \u226436 did not significantly affect assay performance. When coupled with a matrix pooling strategy, the assay drastically increased throughput to thousands of samples per run while reducing the assay cost to cents per sample. In the active screening, CLIP-PCR identified 14 infections, including 4 asymptomatic ones, with &amp;lt;500 tests, costing &amp;lt;US$0.60 for each sample. All positive results were confirmed by standard quantitative PCR.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>CLIP-PCR, by use of dried blood spots with a pooling strategy, efficiently offers a highly sensitive and high-throughput approach to detect asymptomatic submicroscopic infections with reduced cost and labor, making it an ideal tool for large-scale malaria surveillance in elimination settings.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1373\/clinchem.2014.237115","type":"journal-article","created":{"date-parts":[[2015,5,11]],"date-time":"2015-05-11T21:51:38Z","timestamp":1431381098000},"page":"821-828","source":"Crossref","is-referenced-by-count":21,"title":["Capture and Ligation Probe-PCR (CLIP-PCR) for Molecular Screening, with Application to Active Malaria Surveillance for Elimination"],"prefix":"10.1093","volume":"61","author":[{"given":"Zhibin","family":"Cheng","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and School of Basic Medicine, Peking Union Medical College, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duoquan","family":"Wang","sequence":"first","affiliation":[{"name":"National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, WHO Collaborating Center for Malaria, Schistosomiasis, and Filariasis, Key Laboratory of Parasite and Vector Biology, Ministry of Health, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyi","family":"Tian","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and School of Basic Medicine, Peking Union Medical College, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and School of Basic Medicine, Peking Union Medical College, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaodong","family":"Sun","sequence":"first","affiliation":[{"name":"Yunnan Institute of Parasitic Diseases, Puer, Yunnan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning","family":"Xiao","sequence":"first","affiliation":[{"name":"National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, WHO Collaborating Center for Malaria, Schistosomiasis, and Filariasis, Key Laboratory of Parasite and Vector Biology, Ministry of Health, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and School of Basic Medicine, Peking Union Medical College, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2015,6,1]]},"reference":[{"key":"2020022605225123500_B1","doi-asserted-by":"crossref","first-page":"900","DOI":"10.1016\/S0140-6736(13)60310-4","article-title":"The changing epidemiology of malaria elimination: new strategies for new challenges","volume":"382","author":"Cotter","year":"2013","journal-title":"Lancet"},{"key":"2020022605225123500_B2","doi-asserted-by":"crossref","first-page":"e2","DOI":"10.1016\/S2214-109X(13)70002-0","article-title":"Malaria eradication: Is it possible?
