Leishmaniasis has as obligatory intracellular parasitic etiological agents belonging to the genus Leishmania capable of infecting different species of mammals and reproducing them within the mononuclear phagocytic system. Domestic dogs are the main responsible for maintaining the epidemiological chain of the disease, presenting a wide variety of clinical profiles, from apparently healthy to severely affected. The expression of the cytokines from dogs naturally infected with Leishmania (Leishmania) chagasi was evaluated. Blood samples were collected from 50 animals, 20 from positive and symptomatic dogs for Leishmaniasis Canine (CVL), 20 from positive asymptomatic animals and 10 negative. Samples were analyzed by immunochromatographic test Dual Path Platform (DPP/Biomanguinhos®) and by indirect ELISA (EIE/Biomanguinhos®) for detection of anti-Leishmania antibodies. There was statistical difference between the groups observing an increase in IFN-γ levels in asymptomatic animals and an IL-10 increase in symptomatic. |
