Epidemiological serosurveys performed in Europe often lack a thorough assessment of clinical health status of studied dogs. The aim of this study was to evaluate signalment, immunological and parasitological status and clinicopathological findings of L. infantum-seropositive apparently healthy dogs (n = 212) living in endemic areas. Routine laboratory tests, endpoint inhouse ELISA to quantify the anti-Leishmania antibodies, blood Leishmania qPCR and IFN-ELISA were performed. All dogs enrolled were L. infantum-seropositive and were classified as healthy (n = 105) or sick (n = 107) according to LeishVet guidelines. The sick group presented a higher proportion of medium to high antibody levels and positive qPCR and lower IFN-concentration compared to the healthy group. Sick dogs were mostly classified in LeishVet stage IIa. Biochemical alterations (98%) were the most common clinicopathological findings, with fewer urinary tract (46%) and hematological (40%) alterations. Apparently healthy L. infantum-seropositive dogs can be classified between truly healthy dogs and sick dogs with clinicopathological findings. Sick dogs presented medium to high seropositivity and parasitemia and low IFN- concentrations, and their most common clinicopathological abnormalities were serum protein alterations followed by proteinuria and lymphopenia.application/pdfengcc-by (c) Baxarias, Marta et al., 2023https://creativecommons.org/licenses/by/4.0/LeishmàniaGossosMalalties infeccioses en els animalsLeishmaniaDogsCommunicable diseases in animalsinfo:eu-repo/semantics/article7337012023-07-03info:eu-repo/semantics/openAccess
