RESUMO

In Brazil, Blue-fronted Parrot (Amazona aestiva) has been widely owned as a pet bird and, therefore, one of the Brazilians birds most frequently traded illegally in the Black Market. There are few reports in the current literature regarding to the microbiota of wild birds. The gastrointestinal tract of these birds has a wide variety of bacterial species; most of them are Gram positive bacteria and belongs to the lactic acid group. The present study has isolated and identified Lactobacillus, Bifidobacterium, Enterococcus, Pediococcus, and Lactococcus bacterias present in fecal samples of wild and captive Amazona aestiva parrots. Fifty two fecal samples were collected from 26 wild parrots and 26 parrots from commercial breeders. Enterococcus genus was the most frequently isolated (100%), followed by Pediococcus (63.46%), Lactobacillus (28.84%), Lactococcus and Bifidobacterium (15.38%). Twelve species of Enterococcus were identified. E. faecium was the most frequently isolated from the birds representing 63.46%, followed by E. faecalis (57.69%), Enterococcus sp. (46.15%), E. hirae (30.76%), and E. raffinosus (19.23%). P. pentosaceus was identified from 57.69% of the parrots. This specie was the most frequently isolated. Five different species of Lactococcus were found out. Lactococcus sp. was identified from 9.61% of the birds, while L. lactis subsp. lactis represented 3.84%. Fourteen different species of Lactobacillus were isolated, showing the biggest diversity among all the studied genera. L. coryniformis subsp. torquens and L. sanfrancisco were isolated from 7.69% of the birds. Three different species of Bifidobacterium were isolated, and B. bifidum was identified in 9.61% of the birds, being the most frequently isolated. Further studies are needed to a better comprehension of the microbiota in wild birds. Besides comparing differences and similarities between wildlife parrots and pet birds will allow appropriate and less empiric management of those birds in captivity.
