Research of Mycoplasma in the family Psittacidae kept in different captivities in Central Brazil

ABSTRACT:

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.
