Resumo
The objective of this study was to investigate the sanitary and
management characteristics of live-bird resellers as well asidentify and undertake an antigenic characterization of Salmonella
enterica and its sensitivity to antimicrobials. Structured questionnaires
were applied and 627 samples were collected from the cages, consisting
209 samples of excreta, 209 of feed and 209 drinker swabs. These
were processed by conventional bacteriology. The obtained isolates
were subjected to the susceptibility test and to 12 antimicrobial tests
by the disk diffusion method. Of the studied resellers, 91.7% house
Gallus gallus domesticus, together with other animal species; sell birds
with little zoosanitary documentation; have unsatisfactory active
surveillance; and use and sell antimicrobials indiscriminately. The
presence of Salmonella enterica was detected in 1.4% (9/627) of the
samples analyzed in the cages, with 1.9% (4/209) found in excreta,
0.95% (2/209) in feed and in 1.4% (3/209) in drinker swabs. These were
characterized antigenically as Salmonella Heidelberg, Gallinarum,
Risen, Ndolo, Saint Paul, Mbandaka and subsp enterica O:6,7. When
susceptibility to antimicrobials was determined, 44.4% resistance
(4/9) was detected for trimethoprim-sulfamethoxazole, 33.3% (3/9) for
enrofloxacin, 22.2% (2/9) for ciprofloxacin, ceftiofur and amoxicillin and
11.1% (1/9) for tetracycline and fosfomycin. Salmonella Heidelberg, as
well as serovars Gallinarum, Risen, Saint Paul and Mbandaka, showed
resistance to at least one of the tested antimicrobials. Trimethoprim sulfamethoxazole and enrofloxacin were the antimicrobials that
showed the least efficacy. Serovars such as Heidelberg, Gallinarum
and Mbandaka have multiresistance to antimicrobials commonly
used in human and veterinary medicine, implying potential risks to
One Health.
