Aspecto médico veterinário legal das lesões em aves silvestres promovidas por colisões com aeronaves

ABSTRACT The objective of this study was to describe lesions in four birds, victims of collisions with aircraft, coming from the International Airport of Recife/Guararapes Gilberto Freyre, Pernambuco, Brazil. Contused wounds were predominant in birds in this study, characterized by the presence of fractures, bruises and hematomas and justified by the blunt action promoted by the type of vulnerant agent involved (aircraft). The analysis under medico-legal veterinary aspect of lesions in bird strike is essential, because in addition to the attempt to establish a standard for differentiating the aircraft lesions, it can guide the bird strike hazard management programs at airports, since the necropsy allows the identification of the species involved or at least facilitates the obtaining biological material for identification

Anticorpos anti-Toxoplasma gondii em carcarás (Caracara plancus) procedentes da região aeroportuária do Recife, Pernambuco, Brasil

RESUMO Objetivou-se com este estudo pesquisar a ocorrência de anticorpos anti-Toxoplasma gondii em carcarás (Caracara plancus) capturados no Aeroporto Internacional do Recife/Guararapes Gilberto Freyre, Pernambuco, Brasil. Foram analisadas 115 amostras de soros sanguíneos pelo teste de aglutinação modificada (IgG, MAT≥25) utilizando taquizoítos inativados em formalina. Do total de amostras analisadas, 5,21% (6/115) foram positivas para presença de anticorpos anti-T. gondii, 16,67% com título 1:25 (1/06) e 83,33% (5/06) com título 1:50. A ocorrência de anticorpos em carcarás procedentes de região aeroportuária fomenta a preocupação em relação a aspectos ainda pouco elucidados, relacionados principalmente à inserção de aves silvestres na cadeia epidemiológica da toxoplasmose conectada à ação antrópica, tornando próxima a interação entre animais silvestres, domésticos e o homem. Dessa forma, é notória a necessidade de estudos relacionados à dinâmica de transmissão entre os diferentes genótipos existentes nessa tríade e sua relação com o meio ambiente, a fim de determinar a influência dessa espécie animal na cadeia epidemiológica da toxoplasmose

Antibodies to Toxoplasma gondii in Crested Caracara (Caracara plancus) from Recife Airport, Pernambuco, Brazil

<p></p><p>ABSTRACT The objective of this study was to investigate the occurrence of antibodies against Toxoplasma gondii in carcarás (Caracara plancus) captured in the Recife/Guararapes Gilberto Freyre International Airport, in the State of Pernambuco, Brazil. 115 samples of blood sera were tested by the Modified Agglutination Test technique (IgG, MAT > 25) using tachyzoites inactivated in formalin. Of the total of the analyzed samples, 5,21% (6/115) were positive for the presence of antibodies against T. gondii, 16,67% with a titer of 1:25 (1/06) and 83,33% (5/06) with a titration of 1:50. The occurrence of antibodies in caracaras coming from airport region generate concern about aspects still poorly understood, mainly related to the inclusion of wild birds in the epidemiological chain of toxoplasmosis connected to human action, making close interaction between wild animals, domestic and man. Thus, the need for studies related to the dynamics of transmission between the different existing genotypes in this triad is evident as is its relationship with the environment to determine the influence of this animal species in the epidemiological chain of toxoplasmosis.</p><p></p
