Pesquisa de Mycoplasma em aves da família Psittacidae mantidas em diferentes cativeiros no Brasil Central / Research of Mycoplasma in the family Psittacidae kept in different captivities in Central Brazil

O presente estudo teve como objetivo investigar a presença de Mycoplasma gallisepticum e M. synoviae em diferentes espécies de psitacídeos cativos no Brasil Central. Um total de 300 amostras foram coletadas e corresponderam a 41 espécies de psitacídeos da fauna brasileira, provenientes do CETAS, criadouro comercial e criadouro conservacionista. Quatorze espécies apresentaram amostras positivas para M. gallisepticum destacando a maracanã-verdadeira (Primolius maracana) (01/02, 50%), a arara-canindé (Ara ararauna) (15/48, 33,3%) e a jandaia-verdadeira (Aratinga jandaia) (03/10, 30%). Amostras do CETAS obtiveram total de 21,62% (16/74) de amostras positivas, do criadouro comercial 15,7% (19/121) e do criadouro conservacionista 6,66% (7/105). Apenas três espécies foram positivas para M. synoviae sendo essas, a maracanã-pequena (Primolius maracana) (1/10 - 10%), arara-macao (Ara macao) (1/12, 8,3%) e arara-canindé (Ara ararauna) (2/48, 4,1%). O CETAS obteve 2,7% (2/74) de amostras positivas totais, enquanto o criadouro conservacionista obteve total de 1,9% (2/105) de amostras. Não ocorreram amostras positivas para M. synoviae no criadouro comercial. Os resultados mostraram um considerável número de amostras positivas para M. gallisepticum em espécies da família Psittacidae, indicando que estes animais podem ser uma fonte de infecção silenciosa para outras aves, uma vez que não apresentaram sintomatologia clínica.(AU)

The study aimed to investigate the presence of Mycoplasma gallisepticum and M. synoviae in different species of captive parrots, in Central Brazil. A total of 300 samples were collected from 41 brazilian species of Psittacidae at three captivities: Centro de Triagem de Animais Silvestres (CETAS), a conservation and a commercial captivity. Fourteen species presented positive samples for M. galisepticum, the most affected were blue-winged macaw (Primolius maracana) (01/02, 50%), blue-and-yellow macaw (Ara ararauna) (15/48, 33.3%), and jandaia parakeet (Aratinga jandaia) (03/10, 30%). CETAS facility showed 21.62% (16/74) of positive samples, while the commercial captivity showed 15.7% (19/121), and the conservation captivity 6.66% (7/105). Only three species presented positive samples for M. synoviae: blue-winged macaw (Primolius maracana) (1/10, 10%), scarlet macaw (Ara macao) (1/12, 8.3%) e blue-and-yellow macaw (Ara ararauna) (2/48, 4.1%). CETAS facility showed 2.7% (2/74) of positive samples, while the conservation captivity presented 1.9% (2/105), and no positive samples were found in the commercial captivity. Results showed a considerable number of positive samples for M. galisepticum in species of Psittacidae family, indicating that these animals can be a silent source of infection for other birds, since they did not present clinical symptoms.(AU)

[Canine visceral leishmaniasis in dog from Caldas Novas, Goiás]. / Leishmaniose visceral canina em cão de Caldas Novas, Goiás.

The objective of the present work was to describe a visceral case of leishmaniasis in a dog from Caldas Novas, GO, region until then considered as a disease free area. The animal, attended in the Veterinarian Hospital of the Federal University of Goiás, presented loss of weight, alopecic area of irregular format at the nasal back, onicogrifosis, atrophy of the heads muscles and failure of the right popliteus lymphonode. For the laboratorial diagnosis, samples were collected by biopsy from the complete skin of the auricular region, by punsion from the popliteus lymphonode for preparation of Giemsa stained blades and 5 mL of the blood were also collected for serum diagnosis. The direct microscopy revealed, from the evaluation of the imprint obtained from the skin fragment and from the squash of the inhaled lymphonode, great amount of amastigoste forms of Leishmania in the cytoplasm of macrophages. Based on the clinical presentation, on the parasitologic and on the serology examination of the samples, we concluded the exams with the diagnosis of calazar disease.
