“…In particular, ARB that can be found either in water environments or in the human microbiome deserves special attention (Vaz-Moreira et al 2014). The ARB ubiquity explains why nowadays, gene families like bla-TEM, blaCTX-M, blaSHV, and plasmid-mediated quinolone resistance such as (aac-Ib-cr or qnrS), sul 1-3 or tetX/Q/S/W/O/M, besides clinically relevant, can be found in surface water, aquaculture environments, or in wildlife (Costa et al 2006;Simões et al 2010;Vredenburg et al 2014;Xiong et al 2015). If no control measures are taken, in a few years, this same scenario can be observed for other genes such as blaNDM-1 (New Delhi metallo-β-lactamase), blaVIM and blaKPC (carbapenemases), or vanA (vancomycin resistance operon gene), and then it may be too late to act.…”

Over the last decade, numerous evidences have contributed to establish a link between the natural and human-impacted environments and the growing public health threat that is the antimicrobial resistance. In the environment, in particular in areas subjected to strong anthropogenic pressures, water plays a major role on the transformation and transport of contaminants including antibiotic residues, antibiotic-resistant bacteria, and antibiotic resistance genes. Therefore, the urban water cycle, comprising water abstraction, disinfection, and distribution for human consumption, and the collection, treatment, and delivery of wastewater to the environment, is a particularly interesting loop to track the fate of antibiotic resistance in the environment and to assess the risks of its trans-mission back to humans. In this article, the relevance of different transepts of the urban water cycle on the potential enrichment and spread of antibiotic resistance is reviewed. According to this analysis, some gaps of knowledge, research needs, and control measures are suggested. The critical rationale behind the measures suggested and the desirable involvement of some key action players is also discussed.

“…ESBL producers were initially detected in human medical practice, but recent investigations have shown that ESBL producers have been found in farm animals and wild animals [5][6][7][8][9][10]. The increasing number of ESBL-producing isolates found in animals has led to the hypothesis that animals might become infection sources or even reservoirs contributing to the spread of these bacteria [11].…”

Introduction: Animals are considered to be reservoirs of extended-spectrum beta-lactamase (ESBL)-producing bacteria, but few epidemiological data on ESBL-producing Escherichia coli urinary tract isolates in pet dogs are available in China. Methodology: This study was conducted to describe the prevalence and characterization of ESBL producers among E. coli urinary tract isolates from pet dogs in Tai'an, China. Results: A total of 118 E. coli were obtained from urinary samples of 80 companion dogs suffering from acute or chronic cystitis, of which three isolates from different dogs were ESBL producers. One isolate from dog A was of phylogroup A/ST410/CTX-M-15/TEM-1; one from dog B was of phylogroup B1/ST533/CTX-M-15/TEM-1; one from dog C was of phylogroup D/ST648/CTX-M-15. All ESBL producers were resistant to ampicillin, cephalexin, cefalotin, cefpodoxime, ceftiofur, enrofloxacin, marbofloxacin, and trimethoprim/sulfamethoxazole, but were susceptible to imipenem and amoxicillin/clavulanic acid. E. coli of ST533 carrying blaCTX-M-15 were first detected in pet dogs in China. Conclusions: Collectively, the findings could expand our knowledge about the prevalence and characterization of ESBL-producing E. coli urinary tract isolates in pet dogs in China.

“…The ESBLs-CTX-M type was also reported in faecal samples of broilers [22], and healthy pets [23]. ESBLs-producing E. coli strains have been also identified in food animals [24][25] and wild animals [26].…”

“…The emergence of bla CTX-M has been detected in food animal populations [3], food products [4], and both domestic [5] and wild [6] animal species throughout the world. Saudi Arabia is one of many countries with higher rates of bacterial pathogens with ESBLs-producers in the clinical setting, mostly associated with CTX-M-types [7,8].…”
