Resistência antimicrobiana e perfil plasmidial de Escherichia coli isolada de frangos de corte e poedeiras comerciais no Estado de Pernambuco

Abstract: Embora existam linhagens de Escherichia coli não patogênicas para aves, muitas outras possuem a capacidade de causar sérios danos à saúde das mesmas, sendo capazes de ocasionar diferentes tipos de processos infecciosos. As linhagens patogênicas são denominadas Avian Pathogenic Escherichia coli (APEC), possuindo genes relacionados ao processo de patogênese em epissomos (plasmídios) ou no cromossomo. A presença de plasmídios, contendo genes de resistência a antibióticos em linhagens aviárias, patogênicas… Show more

“…A study performed with 91 cloacal swab samples from healthy broiler chickens revealed a con-siderably high resistance rate to this antibiotic (68.1%) [34], which was similar to another report with 86 E. coli strains isolated from air sacs of birds with respiratory signs and identified a 66.7% of isolates resistant to this antibiotic association [7]. However, a study performed in Pernambuco State with 16 E. coli from cecal content of healthy broiler chickens revealed a low resistance rate to trimethoprim-sulfamethoxazole (43.7%) when compared to the present study, while 13 birds that presented clinical signs of respiratory disease revealed a high resistance rate (84.6%) [3]. In addition, recent studies verified elevated resistance in 25 E. coli isolates from cloacal swab samples of healthy broiler chickens to the same antibiotic (84%) [2], unlike what was observed with 60 feces samples of intensive reared broiler chickens, which revealed 45% of resistance to trimethoprim-sulfamethoxazole [19].…”

“…Furthermore, multidrug resistance has been frequently reported. The majority of strains isolated from commercial poultry of Pernambuco State (NE) were MDR (33/35, 94%) [68]. In a study conducted in Bahia State (NE), the majority of ExPEC isolates were resistant to at least four antimicrobial agents from different classes.…”

“…Inibe a divisão celular e o crescimento e produz lise e elongação das bactérias sensíveis, particularmente as que sofrem rápida divisão, pois possuem maior grau de sensibilidade à ação das penicilinas (MISODOR, 2016). Barros et al (2012) isolaram 35 cepas de E. coli de frangos de corte e de poedeiras comercial, e evidenciaram alta percentagem de resistência quanto à amoxicilina e enrofloxacina, o que está próximo do resultado encontrado nesse estudo.…”
