This study evaluated the accuracy of serological tests, immunochromatographic (Dual Path Platform: DPP<jats:sup>\u00ae<\/jats:sup>) and enzyme-linked immunosorbent (ELISA EIE<jats:sup>\u00ae<\/jats:sup>), for CVL in relation to the detection of <jats:italic>Leishmania<\/jats:italic> DNA through real-time polymerase chain reaction (real-time PCR) in samples from symptomatic and asymptomatic dogs from a non-endemic area in the state of Rio Grande do Sul, Southern Brazil. Serum from 140 dogs (39 symptomatic and 101 asymptomatic) was tested by DPP and ELISA followed by real-time PCR. From a total of 140 samples evaluated, <jats:italic>Leishmania<\/jats:italic> DNA was detected by real-time PCR in 41.4% (58\/140). Moreover, 67.2% of samples positive in real-time PCR were positive in both DPP and ELISA (39\/58), showing moderate agreement between methods. In the symptomatic group, one sample non-reactive in both serological assays was positive in real-time PCR, whereas in the asymptomatic group, 17.8% non-reactive or undetermined samples in serological assays were positive in the molecular method. <jats:italic>Leishmania<\/jats:italic> DNA was not detected in 17.9% reactive samples by serological assays from the symptomatic group, and in 3.9% from asymptomatic dogs. Real-time PCR demonstrated greater homogeneity between symptomatic and asymptomatic groups compared with DPP and ELISA. The molecular method can help to establish the correct CVL diagnosis, particularly in asymptomatic dogs, avoiding undesirable euthanasia.<\/jats:p>","DOI":"10.1017\/s0950268818000225","type":"journal-article","created":{"date-parts":[[2018,2,25]],"date-time":"2018-02-25T21:27:41Z","timestamp":1519594061000},"page":"571-576","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":34,"title":["Canine visceral leishmaniasis diagnosis: a comparative performance of serological and molecular tests in symptomatic and asymptomatic dogs"],"prefix":"10.1017","volume":"146","author":[{"given":"Fl\u00e1vio Luiz Nunes","family":"de Carvalho","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emeline de Oliveira","family":"Riboldi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Graziele Lima","family":"Bello","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raquel Rocha","family":"Ramos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0901-2422","authenticated-orcid":false,"given":"Regina Bones","family":"Barcellos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirela","family":"Gehlen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Laura","family":"Halon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro Roosevelt Torres","family":"Rom\u00e3o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliane","family":"Dallegrave","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Lucia Rosa","family":"Rossetti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2018,2,26]]},"reference":[{"key":"S0950268818000225_ref37","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2006.01.011"},{"key":"S0950268818000225_ref1","unstructured":"World Health Organization (2015) Visceral leishmaniasis: control strategies and epidemiological situation update in East Africa, Ethiopia.
