In Brazil, the main strategy adopted to contain Visceral Leishmaniasis (VL) is the controversial culling of dogs with reagent serology for Canine VL (CVL). Despite there are studies showing that significant reduction of human cases has not been observed, as well as there are works demonstrating the occurrence of false-positive results in the confirmatory test, the protocol has been maintained. Researches that can reinforce the existence and persistence of this problem, as well as bring concrete alternatives are pivotal. In this context, the aim of this work was to evaluate and compare the serological, molecular and parasitological methods employed for CVL detection in Brazil, in dogs with diverse clinical profiles, from two endemic areas of Pernambuco state. Comparisons among TR-DPP®, EIE-LVC and qPCR (animals from Goiana-PE: 91) demonstrated that agreements varied from 'poor' to 'moderate' (kappa = 0.162-0.442), and a triple agreement occurred in 61.36% (54/88) of the samples. The highest percentage of agreement was obtained between TR-DPP® and EIE-LVC within the polysymptomatic group (93.33%; 14/15). Of the 34 dogs with reagent serology from Caruaru-PE, 17 (50%) and 29 dogs (85.29%) were positive for qPCR and parasitological exam, respectively. By comparing serology, qPCR and parasitological exam, the lowest percentage of agreements were obtained within the asymptomatic group (40%-72.72%). It was possible to observe that the percentage of agreement tended to decrease according to the absence of clinical manifestations in the dogs. Thus, from the fact that all diagnostic tools evaluated have their limitations, it is very important to be careful before to propose an alternative set of diagnostic criteria. Besides, the answer for better results in the control of CVL may not be in the choose of the best set of diagnostic tools, but it may be in the strategy of culling itself. In this context, it is very important to invest in alternative control measures, such as mass vaccination and treatment of dogs, thus reducing the transmission to the vector and helping to avoid new canine and human cases.
