RESUMO: Este estudo investigou a presença de bactérias potencialmente zoonóticas e resistentes a antimicrobianos em psitacídeos criados em ambiente doméstico. Esse projeto foi aprovado pela Comissão de Ética para o Uso de Animais da Universidade Estadual do Ceará (CEUA-UECE), registrado sob o número 03423745/2023. Foram coletadas 111 amostras de suabes cloacais de psitacídeos exóticos de seis espécies, incluindo, periquitos-australianos (Melopsittacus undulatus), calopsitas (Nymphicus hollandicus), agapornis (Agapornis sp.), periquitos-de-colar (Psittacula krameri), periquitos-dorso-vermelho (Psephotus haematonotus) e roselas (Platycercus eximius). Foi realizado o isolamento e a identificação de enterobactérias e determinado o perfil de resistência. Das amostras coletadas, 70,2% (78/111) apresentaram crescimento para uma ou mais enterobactérias. Foram isoladas 110 cepas pertencentes a 13 espécies bacterianas. Escherichia coli apresentou o maior índice de isolamento, com 30% (33/110). Em segundo lugar Pantoea agglomerans, com um percentual de isolamento de 27,2% (30/110). Observou-se que 35,4% (39/110) das enterobactérias apresentaram resistência à tobramicina, seguidas da tetraciclina com 34,5% (38/110) e da fosfomicina com 30,9% (34/110). E. coli apresentou maior taxa de resistência a tetraciclina com 51,5% (17/33), seguida de 36,6% (12/33) para tobramicina e 15,1% (5/33) para gentamicina. Das enterobactérias analisadas 28,9% (32/110), apresentaram multirresistência. Os resultados indicam uma alta prevalência de enterobactérias, a resistência antimicrobiana foi constatada em diversas classes de antimicrobianos.

ABSTRACT: This investigation elucidated the presence of potentially zoonotic and antimicrobial-resistant bacteria in domestically reared psittacines. The present study was sanctioned by the Animal Ethics Committee of the State University of Ceará (CEUA-UECE) and bears registration number 03423745/2023. A total of 111 cloacal swab samples were procured from exotic psittacines encompassing six distinct species: the Australian budgerigar (Melopsittacus undulatus), cockatiels (Nymphicus hollandicus), lovebirds (Agapornis sp.), rose-ringed parakeets (Psittacula krameri), red-rumped parrots (Psephotus haematonotus), and rosellas (Platycercus eximius). The process encompassed the isolation and characterization of enterobacteria and ascertaining their resistance profiles. Among the collected specimens, 70.2% (78/111) yielded growth indicative of one or more enterobacterial agents. The collective isolates comprised 110 strains encompassing 13 distinct bacterial species. Foremost among these was Escherichia coli, accounting for a significant percentage of the total isolates at 30% (33/110), followed by Pantoea agglomerans at 27.2% (30/110). The study revealed that 35.4% (39/110) of the isolates exhibited resistance to tobramycin, with tetracycline and fosfomycin showing resistance rates of 34.5% (38/110) and 30.9% (34/110), respectively. Particularly noteworthy was that E. coli showed a heightened propensity for tetracycline resistance at 51.5% (17/33), while resistance rates to tobramycin and gentamicin were 36.6% (12/33) and 15.1% (5/33), respectively. A noteworthy subset of the enterobacterial cohort exhibited multidrug resistance patterns (28.9%, 32/110). Collectively, these outcomes underscore not only an elevated prevalence of enterobacterial strains but also the pervasive phenomenon of antimicrobial resistance across a diverse spectrum of antimicrobial agents.
