Background There is limited information available on cytokine profiles in dogs with different degrees of disease severity due to natural infection of Leishmania infantum. The aim of this study was to investigate L. infantum-specific IFN-γ and IL-10 production in blood from dogs with leishmaniosis at diagnosis and correlate these findings with disease severity, humoral immune response and blood parasitemia. Methods Sixty dogs were diagnosed based on physical examination, routine laboratory tests, L. infantum-specific antibody levels measured by quantitative ELISA and blood parasitemia by real-time PCR. Heparin whole blood was stimulated with L. infantum soluble antigen (LSA) and concanavalin A (ConA) and incubated for 5 days. IFN-γ and IL-10 concentrations were measured in supernatants with sandwich ELISAs. Results The majority of dogs (n = 36) were classified as LeishVet stage II (moderate disease). The rest of the dogs were classified as stage I (n = 10), III (n = 10) and IV (n = 4). Dogs classified with stage I and IIa presented significantly higher (P = 0.02) LSA IFN-γ concentrations, lower (P
