This technique was tested on 33 <jats:italic>L. infantum<\/jats:italic> strains from 19 different zymodemes, which were recognized equally. It was also used on human and canine clinical samples. PCR\u2013ELISA has a higher sensitivity than the other techniques used (IFAT, parasite cultures, optical microscopy of stained samples) and permits detection of a minimum of 0.1 promastigotes or 1\u00a0fg of genomic DNA. PCR\u2013ELISA can be used to diagnose human cutaneous leishmaniasis using material obtained by scraping the lesion margin, and human visceral leishmaniasis in HIV(+) individuals and canine leishmaniasis with peripheral blood samples. The presence of <jats:italic>L. infantum<\/jats:italic> in dogs with low antibody titres with IFAT technique (20 and 40) was demonstrated indicating that seroprevalence data from epidemiological studies underestimate the true rates of infection.<\/jats:p>","DOI":"10.1017\/s0031182001007909","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:16:36Z","timestamp":1027775796000},"page":"607-615","source":"Crossref","is-referenced-by-count":43,"title":["Diagnosis of infections with <i>Leishmania infantum<\/i> using PCR\u2013ELISA"],"prefix":"10.1017","volume":"122","author":[{"given":"J.","family":"MARTIN-SANCHEZ","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.\u00a0C.","family":"LOPEZ-LOPEZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"ACEDO-SANCHEZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.\u00a0J.","family":"CASTRO-FAJARDO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.\u00a0A.","family":"PINEDA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"MORILLAS-MARQUEZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2001,7,12]]},"reference":[{"key":"S0031182001007909_ref014","doi-asserted-by":"crossref","unstructured":"LOPEZ-VELEZ, R. , LAGUNA, F. , ALVAR, J. , PEREZ-MOLINA, J.\u00a0A. , MOLINA, R. , MARTINEZ, P. & VILLARRUBIA, J.
