Resumo
Captive Psittaciformes may harbor Gram-negative
bacteria in their digestive tract, mainly due to poor hygienic
conditions and confinement. The present study was
carried out with the objective of isolating and identifyingEscherichia coli in samples collected from Psittaciformes cages
in 50 commercial establishments in the metropolitan region of
Goiania, with subsequent antimicrobial susceptibility testing and
detection of virulence genes. A total of 141 samples of excreta
and swab samples from feeders and water bowls were collected,
totaling 423 samples. Escherichia coli was isolated from 9.7%
(41/423) samples: 12% (17/141) in excreta, 8.5% (12/141) in feed,
and 8.5% (12 /141) in waterers. To determine the susceptibility
profile of E. coli isolates, resistance to ciprofloxacin 4.9% (2/41),
gentamicin 17.0% (7/41), doxycycline 34.1% (14/41), florfenicol
34.1% (14/41), trimethoprim 39.0% (16/41), tetracycline 41.5%
(17/41), enrofloxacin 43.9% (18/41), amoxicillin 48.8% (20/41),
neomycin 61.0% (25/41), and sulfonamide 90.2% (37/41) was
determined. In 20 isolates, resistance was determined at 4
or more antimicrobials, seven of excreta (7/17), five of feed
(5/12), and eight of waterers (8/12). One of the isolates from
the waterers showed resistance to all antimicrobials. The iss
gene was detected in three isolates, the tsh gene in three, the
papC gene in two, traT and eae genes were not detected. In this
study, it can be concluded that Psittaciformes commercialized as
pet are carry E. coli isolates resistant to most commonly used
antimicrobials, mainly sulfonamides and neomycin, besides
having virulence and serum resistance genes, which highlights
the possibility of the to cause disease in humans.
