RESUMEN

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.(AU)

RESUMEN

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.(AU)

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.(AU)

RESUMEN

Objetivou-se com este estudo investigar a ocorrência de Mycoplasma spp., Mycoplasma galissepticum (MG) e Mycoplasma synoviae (MS) em psitacídeos de cativeiro localizado no estado de Pernambuco, Brasil. Foram estudadas 85 aves provenientes do Parque Estadual Dois Irmãos, localizado no estado do Pernambuco, Brasil. De cada psitacídeo analisado foram obtidas três amostras por meio de swabs da cloaca, palato e conjuntiva totalizando 255 amostras. As amostras coletadas foram submetidas à extração de DNA e à reação em cadeia da polimerase (PCR), sendo as positivas submetidas ao isolamento em ágar Frey. O DNA de Mycoplasma spp. foi detectado em 16,47% (14/85) dos psitacídeos estudados. Das 255 amostras analisadas, 6,66% (17/255) foram positivas para a presença de Mycoplasma spp., sendo 41,18% (7/17) provenientes da conjuntiva, 35,29% (6/17) do palato e 23,53% (4/17) da cloaca. Nenhuma amostra foi positiva para MG ou MS na PCR. Os resultados obtidos permitem confirmar a presença do DNA de Mycoplasma spp. em conjuntiva, palato e cloaca nas aves estudadas. Foram detectadas colônias semelhantes a membros da classe Mollicutes em 17,64% das amostras (3/17). Esse é o primeiro relato da presença de Mycoplasma spp. em psitacídeos de cativeiro no Nordeste do Brasil.

The aim of this study was to investigate the occurrence of Mycoplasma spp., Mycoplasma galissepticum (MG) and Mycoplasma synoviae (MS) in captive psittacines. Eighty-five wild birds from Parque Estadual Dois Irmãos, Pernambuco state, northeastern Brazil, were used. From each psittacid analyzed three samples were obtained through cloaca, palate and conjunctiva swabs, totaling 255 samples. Samples collected were submitted to DNA extraction and Polimerase Chain Reaction (PCR). Mycoplasma spp. DNA was detected in 16.47% (14/85) of psittacines studied. From 255 samples, 6.66% (17/255) were positive for Mycoplasma spp.: 41.18% (7/17) of positivity in conjunctiva, 35.29% (6/17) in palate and 23.53% (4/17) in cloaca. There was no positive sample for MG or MS in PCR. Similar colonies were found for members of the Mollicutes Class in 17.64% of the samples (3/17). The results confirmed Mycoplasma spp. DNA in conjunctiva, palate and cloaca from the wild birds analyzed. This is the first record of Mycoplasma spp. in captive psittacines from northeastern Brazil.
