“…One of the major concerns regarding APEC colonization in broiler breeders is the vertical transmission of antibiotic-resistant genes down the poultry production pyramid [79]. Additionally, the possibility of the zoonotic potential of APEC, including the transfer of antibiotic-resistant genes to humans, has been suggested by Johnson et al [66].…”

“…Even though strict biosecurity is practiced at the top level of the breeding pyramid, there are still challenges at the lower levels, especially the broiler parents. Hence, the proper use of antibiotics in broiler breeders is critical [79,80]. Furthermore, more focus on alternative treatment approaches may also help to prevent antibiotic resistance.…”

“…The strain obtained from the chicks that died in the first week was also recovered from the broiler parents by following fluoroquinolone-resistant E. coli that was vertically transmitted down the integrated broiler production chain [82]. Furthermore, the extended-spectrum betalactamase (ESBL) and plasmid ampicillinase C (pAmpC) resistance were also found to be vertically transmitted from broiler breeders to broilers [18,79,83]. Another relevant finding supporting the vertical transmission potential is the recovery of tetracycline-resistant E. coli from the ovary and egg contents of broiler breeders [84].…”

Poultry meat is one of the major animal protein sources necessary to meet the global protein demand. Sustainability in broiler production is the key to achieving its continuous supply, and broiler breeders play a critical role in maintaining this sustainability by providing good quality chicks. Colibacillosis, the disease caused by avian pathogenic Escherichia coli (APEC), causes severe economic losses to the poultry industry globally. Moreover, APEC causes an additional burden among broiler breeders, such as a decrease in egg production and mortality among these birds. There is vertical transmission of APEC to the broiler chicks through eggs, resulting in increased first-week mortality and subsequent horizontal transmission at the hatchery. In this regard, the vertical transmission of antibiotic resistance genes is another concern that needs attention. Controlling several diseases in broiler breeders would possibly reduce the first-week mortality in chicks, thereby maintaining the production level. For that, constant monitoring of the bacterial populations is critical. Moreover, amidst the increased antibiotic resistance pattern, more focus on alternative treatment strategies like vaccines, probiotics, and bacteriophages is necessary. Future research focusing on strategies to mitigate APEC in broiler breeders would be one of the finest solutions for sustainable broiler production.

“…Eggs are important poultry products that play an essential role in the daily healthy diet of human beings and are the most consumed food all over the world [https://www.who.int/zh/newsroom/fact-sheets/detail/salmonella-(non-typhoidal)]. Poultry eggs are also considered as reservoirs and transmission vectors of resistance genes, such as mcr-1, fosA, qnrS1, bla CTX−M−1 , bla IMP , and bla OXA−48−like (Benameur et al, 2018;Kapena et al, 2020;Zhang et al, 2021Zhang et al, , 2022bKanaan et al, 2022;Li et al, 2022). Resistant bacteria and genes in eggs have the risk of spreading to humans through various ways, such as hand-toegg contact and storing unwashed eggs in fridge.…”

The New Delhi Metallo-β-lactamase (NDM) producing Enterobacterales has been detected from diverse sources but has rarely been reported in retail eggs. In this study, 144 eggshell and 96 egg content samples were collected in 2022 from Guangdong province and were screened for NDM-producing strains. Four Escherichia coli strains (ST3014, ST10, ST1485, and ST14747) recovered from two (1.39%, 2 of 144) eggshells and two (2.08%, 2 of 96) egg content samples were identified as blaNDM−5-positive strains. Oxford Nanopore MinION sequencing and conjugation assays revealed that the blaNDM−5 gene was carried by IncX3 (n = 1), IncI1 (n = 1), and IncHI2 (n = 2). The IncI1-plasmid-carrying blaNDM−5 displayed high homology with one plasmid pEC6563-NDM5 from the human clinic, while the IncHI2 plasmid harboring blaNDM−5 shared highly similar structures with plasmids of animal origin. To the best of our knowledge, this is the first report on the identification of blaNDM−5-positive bacteria in retail eggs. NDM-producing E. coli could be transmitted to humans by the consumption of eggs or direct contact, which could pose a potential threat to human health.
