Antibiotic resistance and extended-spectrum β-lactamase in Escherichia coli isolates from imported 1-day-old chicks, ducklings, and turkey poults

Abstract

<jats:p>Aim: Antimicrobial resistance is a global health threat. This study investigated the prevalence of Escherichia coli in imported 1-day-old chicks, ducklings, and turkey poults. Materials and Methods: The liver, heart, lungs, and yolk sacs of 148 imported batches of 1-day-old flocks (chicks, 45; ducklings, 63; and turkey poults, 40) were bacteriologically examined for the presence of E. coli. Results: We isolated 38 E. coli strains from 13.5%, 6.7%, and 5.4% of imported batches of 1-day-old chicks, ducklings, and turkey poults, respectively. They were serotyped as O91, O125, O145, O78, O44, O36, O169, O124, O15, O26, and untyped in the imported chicks; O91, O119, O145, O15, O169, and untyped in the imported ducklings; and O78, O28, O29, O168, O125, O158, and O115 in the imported turkey poults. The E. coli isolates were investigated for antibiotic resistance against 16 antibiotics using the disk diffusion method and were found resistant to cefotaxime (60.5%), nalidixic acid (44.7%), tetracycline (44.7%), and trimethoprim-sulfamethoxazole (42.1%). The distribution of extended-spectrum β-lactamase (ESBL) and ampC β-lactamase genes was blaTEM (52.6%), blaSHV (28.9%), blaCTX-M (39.5%), blaOXA-1 (13.1%), and ampC (28.9%). Conclusion: Imported 1-day-old poultry flocks may be a potential source for the dissemination of antibiotic-resistant E. coli and the ESBL genes in poultry production.</jats:p>

Environmental Perturbations during the Rehabilitation of Wild Migratory Birds Induce Gut Microbiome Alteration and Antibiotic Resistance Acquisition

“…Dietary modifications during rehabilitation may also have contributed to the acquisition of antibiotic resistance in wild birds. Indeed, 1-day-old chicks are a major source of in-farm-transmitted antibiotic resistance owing to their high antibiotic resistance levels ( 58 , 59 ). The remaining antibiotic-resistant microorganisms in the guts of chicks could have colonized the guts of wild birds during rehabilitation, resulting in increased antibiotic resistance.…”

Occurrence of Multidrug Resistant Escherichia coli in Raw Meat and Cloaca Swabs in Poultry Processed in Slaughter Slabs in Dar es Salaam, Tanzania

“…On the other hand, cefotaxime, and especially imipenem, which are not commonly used [ 23 ], were less resistant. ESBL-producing E. coli were detected in 10/212 (4.7%) and quinolone resistance genes in 80% of them, supporting observations of several studies that have found a strong association between qnr-positive and ESBL-positive isolates [ 24 , 25 , 26 , 27 ].…”

Antibiotic profiling of multidrug resistant pathogens in one-day-old chicks imported from Belgium to benin

“…No studies have been carried out on the screening of pathogens present in these chicks or their sensitivity to antibiotics. However, there is ample scientific evidence that the importation of day-old chicks can contribute to the introduction of resistant strains of bacteria into chicken farms [ 20 , 21 ].…”
