Surveillance and monitoring of wildlife pathogens are essential in the environmental context and human public health, as these animals act as sentinels, reflecting environmental changes early on, whath gives more efficient environmental monitoring and allows quick access to information on the conditions of area. Birds are important in the epidemiology and life cycle of Toxoplasma gondii, because their tissues are important source of protein in the diet of felids and humans. The objective was to determine antibodies to Toxoplasma gondii in wild birds from three Federal Conservation Units of the states of Paraíba and Bahia by Modified Agglutination Test (MAT). From December 2011 to October 2013, 222 wild birds of 67 species from 27 families and 12 Orders were captured with mist nets. Blood samples were then collected and the serum was separated by centrifugation. The sera were tested (MAT≥1:25) using formalin-fixed whole tachyzoites and 2-mercaptoethanol. Antibodies to T. gondii were found in 3 of 222 (1.3%) birds: in 1 of 16 (6.2%) white-lined tanager (Tachyphonus rufus, titer 50), in 1 of 5 (20%) gray-fronted dove (Leptotilla rufaxila, titer 50), and in 1 of 1 (100%) ashy-throated casiornis (Casiornis fuscus, titer 25). This is the first report of occurrence of antibodies to T. gondii in these tree bird species from two Federal Conservation Units. |
