Resumo
The chlamydiosis or ornithosis is a major zoonosis of avian origin and it is
important for poultry breending. This study was carried out in order to
investigate the presence of Chlamydophila psittaci in pigeons (Columba livia),
turkeys (Meleagris gallopavo domesticus), broilers and free-range chickens
(Gallus gallus domesticus) and to estimate the occurrence of infected animals in
the Center-Souther region of the State of Goias. Cloacal and tracheal swabs
were colleted fron 120 pigeons captured near farms, 300 broiler chickens, 240
turkeys and 240 free-range chickens, analyzed by polymerase chain reaction
(PCR). We obtained by the PCR, 6,7% (8/120) positive trachea and cloaca
swabs in pigeons, 5,8% (7/120) positive tracheas swabs, and 17,5 % (21/120)
positive cloacal swabs, totaling 30% (36/120) of birds infected with C. psittaci.
We did not detect the bacterium in samples from broilers and turkeys. We found
17,5% (42/240) positive free-range chickens, being 8,3% (20/240) positive
trachea and cloaca swabs, 6,7% (16/240) positive swabs and 2,5% (6/240)
cloacal swabs. We concluded that the birds as well free- range chickens are
carries of C. psittaci while broilers and turkeys were not infected.
