“…Among all kinds of bacterial resistance, the CTX-M extended spectrum beta-lactamase (ESBL) is the most dominant beta-lactam enzyme, and it is found mostly among the members of Enterobacteriaceae (1). In recent years, the CTX-M gene has been reported in different countries (2)(3)(4)(5). The CTX-M β-lactamase family can be divided into five groups based on their amino acid identities (6): the CTX-M-1, CTX-M-2, CTX-M-8, CTX-M-9, and CTX-M-25 groups.…”

CTX-M extended spectrum beta-lactamase-producing Escherichia coli cause severe health hazards in livestock breeding. To date, little is known about antibiotic resistance differences among bacterial isolates from yaks, cows, and beef cattle; therefore, the aims of this study were to analyse the prevalence of CTX-M-producing E. coli in yak, beef cattle, and dairy cattle feces from different provinces in China. A total of 790 fecal samples from yaks, beef cattle, and dairy cows were used. Among all the samples, 523 non duplicate E. coli isolates were identified, and 29.6% of samples harbored CTX-M producers. The results showed that these E. coli strains harbored 15 clusters of CTX-M genes: CTX-M-79, CTX-M-55, CTX-M-15, CTX-M-14, CTX-M-28, CTX-M-179, CTX-M-65, CTX-M-24, CTX-M-27, CTX-M-102, CTX-M-105, CTX-M-173, CTX-M-238, CTX-M-196, and CTX-M-10. The dominant resistance genes were CTX-M-15, CTX-M-14, and CTX-M-55. Moreover, the distribution of CTX-M genes was related to geographical region. Based on the above findings, we reasoned that bovines are potential reservoirs of antibiotic resistance, and this problem should be given adequate attention.

“…In their analysis of chicken faeces from backyard chickens in Vietnam, Kawahara et al (2019) found that 97.2% of the chickens carried E. coli harbouring the mcr gene. Le et al (2021) investigated colistin resistance in ESBL-producing E. coli isolated from chickens. They found that 53.2% of ESBL-producing E. coli isolates were colistin-resistant, and all of these colistin-resistant isolates harboured mcr-1 (Le et al 2021).…”

Although the spread of plasmid-mediated antibiotic-resistant bacteria is a public health concern, food contamination with plasmid-mediated antibiotic-resistant Escherichia coli has not been well investigated in Vietnam. The aim of this study was to describe the prevalence of colistinresistant, carbapenem-resistant and endemic bla CTX−M in extended-spectrum β-lactamase (ESBL)-producing E. coli isolates. Colistin-and carbapenemresistant ESBL-producing E. coli were isolated from chickens in Vietnam and Japan. The results showed that 52% and 93% of Vietnamese chicken was isolated with colistin-resistant and AmpC/ESBL-producing E. coli, respectively, while 52.7% of Japanese chickens were isolated with AmpC/ESBLproducing E. coli. Carbapenem-resistant E. coli has not been isolated in Vietnam or Japan. Genotyping revealed that colistin-resistant E. coli harboured mcr-1, and most of the AmpC/ESBL-related genes were bla CTX−M−55 and bla CTX−M−65 together with bla TEM in Vietnamese chickens, and bla CMY−2 in Japanese chickens. Multidrug resistance analysis showed that ESBL-producing E. coli isolates were more resistant to quinolones, streptomycin, and chloramphenicol compared with colistin-resistant E. coli isolates from Vietnam, suggesting selection in ESBL-producing E. coli for multiple antibiotic resistance genes. In conclusion, colistin-resistant E. coli was detected in about half of the chicken meat samples, the majority of which were found to harbour mcr-1. The high prevalence of ESBL-producing E. coli has remained constant across the last ve years, and the predominant bla CTX−M for ESBL-producing E. coli was found to be bla CTX−M−55 or bla CTX−M−65 , with the coexistence of bla TEM in Vietnam. Our results can be implemented in monitoring systems to combat the development of antimicrobial resistance.

“…The genes bla CTX−M−1 and bla CTX−M−9 were each identified in 6 E. coli isolates from shrimp; bla TEM and bla SHV genes were isolated from 10 K. penumoniae isolates [ 52 ]. A study from Vietnam identified ESBL- E. coli in 19.6% (22/112) of retail shrimp examined [ 53 ]. Finally, a study from the United States found bla CTX−M in 42% and bla SHV genes in 6% of domestic wild caught imported shrimp; no ESBL genes were found in farmed shrimp imported from Ecuador [ 54 ].…”

A scoping review of the distribution and frequency of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in shrimp and salmon

Antimicrobial-resistant (AMR) bacteria are a threat to public health as they can resist treatment and pass along genetic material that allows other bacteria to become drug-resistant. To assess foodborne AMR risk, the Codex Guidelines for Risk Analysis of Foodborne AMR provide a framework for risk profiles and risk assessments. Several elements of a risk profile may benefit from a scoping review. To contribute to a larger risk profile structured according to the Codex Guidelines, our objective was to conduct a scoping review of the current state of knowledge on the distribution, frequency and concentrations of extended-spectrum β-lactamase (ESBL)producing Enterobacteriaceae in salmon and shrimp. Articles were identified via a comprehensive search of five bibliographic databases. Two reviewers screened titles and abstracts for relevance and characterized full-text articles with screening forms developed a priori. Sixteen relevant studies were identified. This review found that there is a lack of Canadian data regarding ESBL-producing Enterobacteriaceae in salmon and shrimp. However, ESBL-producing Escherichia coli, Klebsiella pneumoniae, and other Enterobacteriaceae have been isolated in multiple regions with a history of exporting seafood to Canada. The literature described herein will support future decision-making on this issue as research/surveillance and subsequent assessments are currently lacking.
