The World Health Organization (WHO) recommends a limit equal to or lower than one parasitic helminth egg per liter, to reuse reclaimed water for unrestricted irrigation. We present two new protocols of DNA extraction from large volumes of reclaimed water. Quantitative PCR (qPCR) and digital PCR (dPCR) were able to detect low amounts of<jats:italic>A. lumbricoides<\/jats:italic>eggs. By using the first extraction protocol, which processes 500\u2009mL of reclaimed water, qPCR can detect DNA concentrations as low as one<jats:italic>A. lumbricoides<\/jats:italic>egg equivalent, while dPCR can detect DNA concentrations as low as five<jats:italic>A. lumbricoides<\/jats:italic>egg equivalents. By using the second protocol, which processes 10\u2009L of reclaimed water, qPCR was able to detect DNA concentrations equivalent to 20<jats:italic>A. lumbricoides<\/jats:italic>eggs. This fact indicated the importance of developing new methodologies to detect helminth eggs with higher sensitivity and precision avoiding possible human infection risks.<\/jats:p>","DOI":"10.1155\/2017\/7515409","type":"journal-article","created":{"date-parts":[[2017,3,9]],"date-time":"2017-03-09T21:04:51Z","timestamp":1489093491000},"page":"1-9","source":"Crossref","is-referenced-by-count":22,"title":["Quantitative PCR and Digital PCR for Detection of<i>Ascaris lumbricoides<\/i>Eggs in Reclaimed Water"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3989-0218","authenticated-orcid":true,"given":"Lucrecia","family":"Acosta Soto","sequence":"first","affiliation":[{"name":"Department of Soil and Water Conservation and Organic Waste Management, Centro de Edafologia y Biologia Aplicada del Segura (CEBAS-CSIC), Campus de Espinardo, P.O.
