Global poliovirus surveillance has relied on poliovirus isolation in cells, which may take a minimum of 10 days, involves maintaining two cell lines, and propagates virus in high titers. With eradication underway, a major objective of the Global Polio Eradication Initiative (GPEI) is to develop culture-independent detection of polioviruses as an alternative method to complement the current virus isolation technique. A culture-independent method on poliovirus-positive stool suspensions was assessed with commercially available recombinant soluble poliovirus receptor (PVR) coupled to Histidine (His) tags. Viral RNA was screened by quantitative real-time reverse transcription PCR using the poliovirus intratypic differentiation kit. Poliovirus recovery was optimized with PVR-His\u2013tagged protein and buffers supplemented with polyethylene glycol. To validate the poliovirus-PVR\u2013His tag purification assay, 182 poliovirus-positive stools of programmatic importance were parallel tested against the GPLN-accepted virus isolation method. The PVR-His tag enrichment method detected poliovirus in 164 of 171 poliovirus-positive stools, whereas the virus isolation method misidentified 38 stools as poliovirus-negative (McNemar \u03c7<jats:sup>2<\/jats:sup> <jats:italic>p<\/jats:italic>&lt;0.0001). Using this method in combination with RNA extraction, viral RNA recovery increased and showed similar (WPV1) or higher (Sabin 1) sensitivity than the World Health Organization accredited variation of the virus isolation method. The PVR-His enrichment method could be a viable addition to poliovirus surveillance; similar methods have the potential to capture other human pathogens such as EV71 using an appropriate soluble His tag receptor.<\/jats:p>","DOI":"10.1371\/journal.pone.0259099","type":"journal-article","created":{"date-parts":[[2021,11,2]],"date-time":"2021-11-02T17:36:18Z","timestamp":1635874578000},"page":"e0259099","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":6,"title":["Direct detection of polioviruses using a recombinant poliovirus receptor"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5696-8318","authenticated-orcid":true,"given":"Nancy","family":"Gerloff","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Mandelbaum","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Pang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikail","family":"Collins","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brittani","family":"Brown","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chelsea","family":"Harrington","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessica","family":"Hecker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chadi","family":"Agha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cara C.","family":"Burns","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Everardo","family":"Vega","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,11,2]]},"reference":[{"key":"pone.0259099.ref001","volume-title":"Fields Virology","author":"A Mark","year":"2013","edition":"6"},{"key":"pone.0259099.ref002","unstructured":"WHO.
