Resumo
The investigation of pathogens in wild animals can be considered an important tool for conservation of species and ecosystem. Chlamydiosis was first identified and is a common disease in psittacines. It is considered the most important zoonosis spread by these birds. Due to its infectious nature, this disease is studied all around the world. The mycoplasmosis is a common respiratory disease in pigeons, chickens and birds. However, parrots can be affected if they get in contact with the agent, and they can become a source of infection for the environment and for other birds. This study aimed to identify, through the polymerase chain reaction PCR technique, bacteria Chlamydophila spp., Mycoplasma gallisepticum and M. synoviae in captivity parrots in three different facilities in Goiás state: CETAS Centro de Triagem de AnimaisSilvestres, a conservation and a comercial captivity. The results were compared in order to determine wich facility is more perserved or contaminated by pathogens. For Chlamydophilaspp, CETAS facility showed 25.6% of positive samples, while the commercial captivity showed 26.4%, and the conservation captivity had no positive samples (0%). For the presence of Mycoplasma gallisepticum, CETAS presented 21.62% of positive samples, while the commercial and conservation captivity showed 15.7% and 14% of positive samples, respectively. M. synoviae was almost absent in CETAS (2.7%) and in conservation captivity (1.3%), and absent in commercial captivity (0%). The results found were compared using Fischer s exact test, where CETAS and commercial captivity were more infected than conservation captivity. The bacteria studied were present in different species of parrots, especially on the genera Ara, Aratinga and Amazonas. The presence of Chlamydophila and Mycoplasma sp. should be investigated in captive birds, since it reveals the presence of the agents in the population, allowing its control.
