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.

A vigilância e monitoramento de doenças em animais silvestres são imprescindíveis no contexto ambiental e de saúde pública, pois estes animais agem como sentinelas, refletindo alterações ambientais precocemente, o que proporciona maior eficácia no monitoramento ambiental e permite o acesso rápido a informações sobre as condições da área. Neste contexto, as aves são importantes no ciclo biológico do Toxoplasma gondii e na epidemiologia da toxoplasmose, principalmente porque seus tecidos representam importantes fontes de proteína na alimentação de felídeos e humanos. Objetivou-se detectar anticorpos anti-T. gondii, por meio do teste de aglutinação modificada em aves silvestres de três Unidades de Conservação (UC) Federais dos Estados da Paraíba e Bahia. No período de dezembro de 2011 a outubro de 2013 foram capturadas com redes de neblina 222 aves silvestres pertencentes a 67 espécies, 27 famílias e 12 ordens. Após a captura, foi colhido sangue de cada animal e separado o soro, que foi submetido ao Teste de Aglutinação Modificada (MAT≥1:25) utilizando taquizoítos inativados na formalina e 2-mercaptoetanol. Dentre as 222 amostras analisadas, três (1,3%) foram sororreagentes: 1 de 16 (6,2%) pipira-preta Tachyphonus rufus (título 50), 1 de 5 (20%) juriti-gemedeira Leptotila rufaxilla (título 50) e 1 de 1 (100%) caneleiro-enxofre Casiornis fuscus (título 25). Este é o primeiro relato da ocorrência de anticorpos anti-T. gondii nas referidas espécies de aves silvestres de vida livre nas duas UC Federais estudadas.

From 253 wild birds attended at the Wild Animal Ambulatory of the Veterinary Hospital, Paraná Federal University, between August 2003 and August 2006, 45 cases (17.8%) were related to the species Serinus canarius (Belgian Canary). Within these attended birds and its respective orders, most morbid conditions occurred with the Psittaciforme order and were caused by traumatism, in 45 cases (14.32%). Of these, 17 animals (30.91%) had bone fractures; the most common were on radius-ulna (17.65%). Other conditions were presence of ectoparasites (12.50%) and endoparasites (10.68%), respiratory disease (10.42%), dermatological ailments (6.51%), neoplasms (4.95%), ophthalmic illnesses (4.43%), gastrointestinal diseases (3.91%), cachexia (3.39%), neurological diseases (2.86%), self-mutilation (2.86%), obesity (2.34%), aggression by other animals (1.56%), nutritional deficiencies (1.30%), egg retention (1.04%), avian poxvirus (0.78%) and uric gout (0.52%), as well as there was clinical routine measures to be taken (7.55%). Traumas and illnesses were observed as the highest prevalence on the casuistic, which could be prevented by correct husbandry practices.
