CD45+, CD68+ and E-cadherin+ expressions in skin dogs naturally infected by Leishmania infantum

Background: In canine leishmaniasis (CanL), infection occurs through phlebotomine vectors that inoculate the protozoan Leishmania infantum into the skin that infected macrophages and activated dendritic cells (CD). Dogs with CanL present variable clinical manifestations, being common the presence of cutaneous lesions. The aim of this study was to evaluate the expression of CD45+ , CD68+ and E-cadherin+ associating the skin sentinels cells and to compare the clinical-dermatological manifestations in the skin of dogs naturally infected by L. infantum. Materials, Methods & Results: Dogs infected (n = 22) by L. infantum were divided into asymptomatic group (AD, n = 9), and symptomatic group (SD, n = 13), according criteria based on the presence or absence of skin changes. Dogs non-infected (CD, n = 5) were included as control group. Samples of skin biopsies collected from scapular region were processed by routine histology and labeled by immunohistochemistry with monoclonal antibodies against CD45+ , CD68+ and E-cadherin+ , and were described as none, mild, moderate and intense. SD presented keratoconjunctivitis, onychogryphose, lichenification, depigmentation, alopecia, hypotrichosis, erythematous dermatitis, exfoliative dermatitis, ulcerative dermatitis and crusted dermatitis, and the frequency these alterations was expressed as percentage.
