Resumo
The current study was developed to investigate the presence of Escherichia coli
and Salmonella sp., to determine the antimicrobial susceptibility profile and to
detect virulence genes of Escherichia coli isolates. For the study, 50
establishments were selected in Goiânia and municipalities in the metropolitan
region, in which 141 samples of excreta were collected, 141 of feed, and 141
drinkers' swabs of psittacine kept in cages for resale. Samples were submitted to
conventional bacteriology and PCR and Escherichia coli was identified in 9.7%
(41/423) of the samples, 12% (17/141) in excreta, 8.5% (12/141) in the feed and
8.5% (12/141) in the drinkers' swabs. In the determination of antimicrobial
susceptibility of Escherichia coli samples isolated, was found resistance to
ciprofloxacin 4.9% (2/41), gentamicin 17% (7/41), doxycycline 34.1% (14/41),
florfenicol 34.1% (14/41), trimethoprim 39% (16/41), tetracycline 41.5%
(17/41), enrofloxacin 43.9% (18/41), amoxycillin 48.8% (20/41 ), neomycin 61%
(25/41) and sulfonamide 90.2% (37/41). The iss gene was detected in three
isolates, tsh in three, papC in two and the traT and eae genes were not detected.
Salmonella sp. was not isolated in the samples. It concludes that Escherichia coli
isolates show resistance to the most commonly used antimicrobials and the
possibility exists that these birds are carriers of pathogenic strains.
