Performance of IFAT, ELISA, direct parasitological examination and PCR on lymph node aspirates for canine visceral leishmaniasis diagnosis

Abstract: Canine visceral leishmaniasis (CVL) is endemic in numerous Brazilian regions. The greatest difficulty in controlling the disease is the diagnostic limitation. In the present study, the most common tests employed for visceral leishmaniasis diagnosis were compared: immunofluorescence antibody test (IFAT), immunoenzymatic assay (ELISA), direct parasitological examination and polymerase chain reaction (PCR). Samples of lymph node aspirates and blood were collected from 100 dogs that lived in an endemic area (Bauru… Show more

“…Thus, the sensitivity and specificity may be different between several diagnostic tests. According to Camargo et al (2010), even if the PCR technique is in huge demand for the diagnosis of CanL due to its high accuracy, this technique can reveal false-negative results in some cases. This study showed that the specificity of qPCR was 100 %, but it proved less sensitive.…”

“…Os testes sorológicos evidenciam a presença de anticorpos circulantes, mas podem falhar, por exemplo, no período pré-patente e antes da soroconversão (50). Pode realizar-se também, os métodos moleculares, como PCR de aspirados da medula óssea e linfonodos (51).…”

“…Este também utiliza o antígeno rK39, fato que melhora a sensibilidade dos testes (8). Alguns laboratórios utilizam a reação de imununofluorescência indireta (RIFI), bem como outros capazes de detectar a presença de anticorpos ou o próprio agente (9).…”
