“…A high prevalence of E. coli from broiler chicken (89.3%) and farm environment (53.3%) was recorded, which can be influenced by factors such as age, strains and husbandry system of broiler chicken. For instance, the prevalence of E. coli is higher in free-range chickens than caged chickens [16]. However, similar to this study, a high prevalence of E. coli was recorded in chickens in Bangladesh [2][3][4]17].…”

The emergence of antimicrobial resistance in commensal bacteria poses a serious public health burden worldwide. Commensals can disseminate the resistance genes to pathogenic bacteria causing life-threatening infections. This cross-sectional study was designed to investigate the antimicrobial resistance pattern and molecular mechanism(s) of ciprofloxacin resistance in commensal E. coli from three major one health components (humans, animals and the environment) in Bangladesh. Samples were randomly collected from broiler chickens, broiler farm environments and hospitalized human patients from the same geographical area. Isolation and identification of E. coli were performed following standard bacteriological techniques. Antimicrobial susceptibility testing (AST) was performed by disk diffusion and broth microdilution methods. Mutation at the quinolone-resistance determining region (QRDR) was analyzed by sequencing. Of 450 samples, a total of 287 (63.8%; 95% CI 59.2–68.1%) E. coli strains was isolated, where 240 (83.6%; 95% CI 78.9–87.5%) strains were phenotypically resistant to ciprofloxacin. The prevalence of ciprofloxacin-resistant E. coli in broiler chicken, broiler farm environments and hospitalized human patients are 77.6%, 88.8% and 89% respectively. In AST against nine antimicrobials, all the isolates were found to be multidrug-resistant (MDR). The minimum inhibitory concentration (MIC) of ciprofloxacin was ranged from 4 to >128mg/L. Point mutations were detected in several sites of QRDR, specifically at 83 and 87 amino acid positions in gyrA gene, and 56, 57, 78, 80 and 84 amino acid positions in parC gene. Mutations resulted in amino acid substitutions. Phylogenetic analysis of gyrA and parC gene sequences showed a close relationship between the strains isolated from different sources. This study demonstrates a high prevalence of ciprofloxacin resistance in commensal E. coli in humans, animals and environment interface and their genealogically similarity poses an alarming public health consequence.

“…The widespread use of antimicrobials in food animal production, including poultry production, raises a significant global public health concern that is often associated with the emergence of resistance against antimicrobials that are commonly used in those animals [ 8 , 9 , 10 ]. Humans are exposed to resistant microorganisms through the consumption of raw or inadequately cooked eggs added to some desserts and sauces [ 11 ] or from cross-contamination during meal preparation [ 12 ], which promotes the risk of therapeutic failures if humans are infected with multidrug-resistant bacteria [ 13 , 14 ].…”

Comparison of Antimicrobial Resistance among Commensal Escherichia coli Isolated from Retail Table Eggs Produced by Laying Hens from the Cage and Non-Cage Housing Systems in Western Australia

Antimicrobial resistance (AMR) has become a global public health concern in recent decades. Although several investigations evaluated AMR in commensal and pathogenic bacteria from different foods of animal origin in Australia, there is a lack of studies that compared AMR in commensal E. coli isolated from retail table eggs obtained from different laying hen housing systems. This study aimed to determine AMR and differences in AMR patterns among E. coli isolates recovered from retail table eggs sourced from caged and non-caged housing systems in Western Australia. Commensal E. coli isolates were tested for susceptibility to 14 antimicrobials using a broth microdilution method. Clustering analyses and logistic regression models were applied to identify patterns and differences in AMR. Overall, there were moderate to high frequencies of resistance to the antimicrobials of lower importance used in Australian human medicine (tetracycline, ampicillin, trimethoprim, and sulfamethoxazole) in the isolates sourced from the eggs of two production systems. All E. coli isolates were susceptible to all critically important antimicrobials except the very low level of resistance to ciprofloxacin. E. coli isolates from eggs of non-caged systems had higher odds of resistance to tetracycline (OR = 5.76, p < 0.001) and ampicillin (OR = 3.42, p ≤ 0.01) compared to the isolates from eggs of caged systems. Moreover, the number of antimicrobials to which an E. coli isolate was resistant was significantly higher in table eggs from non-caged systems than isolates from caged systems’ eggs. Considering the conservative approach in using antimicrobials in the Australian layer flocks, our findings highlight the potential role of the environment or human-related factors in the dissemination and emergence of AMR in commensal E. coli, particularly in retail table eggs of non-cage system origin. Further comprehensive epidemiological studies are required to better understand the role of different egg production systems in the emergence and dissemination of AMR in commensal E. coli.

Salmonella enterica serotype Enteritidis (SE) is a pathogenic bacteria frequently isolated from shell eggs. Among the surface pasteurization methods, infrared heating provides an easy and eco‐friendly application. To eliminate SE on the surface of shell eggs, pasteurization was applied via two different approaches. First, conventionally far‐IR‐heated eggs were pasteurized for 480 s, 5‐log SE reduction was achieved, but finally they were soft‐cooked. As a second approach, eggs were far‐IR‐heated (60 s) then cooled (+4°C, 120 s) continuously, and this process was repeated five times. As a result of this process, 5‐log SE reduction was achieved with no quality changes inside the eggs. Although the physical (yolk‐index, Haugh‐unit, pH) and functional (foaming capacity) properties of conventionally pasteurized eggs began to change after 110 s, no change was observed inside the egg quality when the second method was applied. These results indicate that a continuous far‐IR‐heating–cooling combination system could be applied for the surface pasteurization of shell eggs. Novelty impact statement The inactivation of Salmonella, which can cause a serious health hazard, is also very important. In this study, it’s shown that applying FIR heating and cooling successively could eliminate SE on the surface of shell eggs without adverse effect in the shell egg. The fact that there is no waste, due to the process, and the easy applicability of the FIR heating creates its superiority over the other methods. This process could be applied to different products as well as a pre‐treatment of the egg process to maintain microbial safety.
