pRKZ3 is a non-conjugative IncQ plasmid, while pKANJ7 is a conjugative IncX plasmid. The optimal mating time of pKANJ7 varied under different conditions. Both of the two transferable ARPs had little impact on the growth of their hosts. A relatively high level of fitness cost was observed for pKANJ7. The fitness cost of ARPs depended on their hosts.

The concentrations of four types of antibiotics in the Yitong River were detected. The concentration of total coliforms in summer was higher than that in spring. There was a seasonal difference in antibiotic resistance of E. coli. The E. coli in the Yitong River was found to have multiple antibiotic resistance.

结直肠癌是全球第三大癌症。宏基因组学已被广泛用于基于细菌属或种水平的比较来分析肠道微生物群与结直肠癌之间的关系,为结直肠癌发展中的生态失调提供了证据。然而,这种分析并不能为我们提供菌株水平的信息,进而理解一种细菌在结直肠癌发生发展中菌株水平的作用。本文利用培养组学方法分离结直肠癌黏膜样本,并选择了158株大肠杆菌,通过系统发育分析和炎症诱导实验,揭示它们在基因组学和功能上的差异。基因组比较可以将这些菌株分为5个系统群。选择代表性菌株进行THP-1细胞(人白血病单核细胞)Transwell实验以及动物实验,结果显示不同菌株经刺激后,细胞因子水平有显著性差异。进一步的生物信息学分析揭示了不同系统群间单核苷酸多态性、基因和代谢途径的不同特征,这些结果有助于了解这些菌株之间的表型差异。细菌菌株在基因组学和功能上的差异表明,菌株水平上的功能差异可以进一步了解宿主与肠道细菌的相互作用机制。

Although carbapenem use is prohibited in animals in China, carbapenem-resistant Escherichia coli (CREC), especially New Delhi metallo-β-lactamase (NDM)-producing strains, are widely prevalent in foodproducing animals. At present, the impact of livestock-associated CREC strains on human populations at the national level is unknown. Here, we conduct a retrospective cross-sectional study to investigate the prevalence of CREC from clinical settings across 22 Chinese provinces or municipalities and analyze anthropogenic factors associated with their presence. We also ascertain the blaNDM and blaKPC abundance among pig and chicken farms and present a detailed genomic framework for CREC of animal and human origin. Overall, 631/29799 (2.1%) clinical Escherichia coli (E. coli) isolates were identified as CREC. Multivariable analysis revealed that being male, an age below 1, an age between 13 and 18, provinces with greater chicken production, and provinces with higher pig production were associated with higher odds of CREC infection. In general, 73.8% (n = 45/61) of pig farms and 62.2% (n = 28/45) of chicken farms had a blaNDM abundance of 1×10-5 to 1×10-3 and 1×10-3 to 1×10-2, respectively. Among all the Chinese NDM-positive E. coli (n = 463) available at the National Center for Biotechnology Information (NCBI), the genomic analysis revealed that blaNDM-5 and IncX3 were the predominant carbapenemase gene-plasmid combination, while a highly homogeneous relationship between NDM-positive isolates from humans and animals was demonstrated at the plasmid and core genome levels. All the findings suggest frequent CREC transmission between humans and animals, indicating that further discussions on the use of antibiotics in animals and humans are needed, both in China and across the globe.

This study was designed to investigate the molecular epidemiology of mobile colistin resistance (mcr) using a "One-Health" approach in Laos and to predict whether any dominant plasmid backbone and/or strain type influences the dissemination of mcr. We collected 673 samples from humans (rectal normal flora), poultry, and the environment (water, flies, birds, etc.) in Vientiane, Lao People's Democratic Republic (Laos), from May to September 2018. A total of 238 Escherichia coli (E. coli) isolated from nonduplicative samples, consisting of 98 MCR-positive E. coli (MCRPEC) ("mcr" denotes the gene encoding mobile colistin resistance, and "MCR" denotes the subsequent protein encoded by mcr) and 140 MCRnegative E. coli (MCRNEC), were characterized by phenotype and Illumina sequencing. A subset of MCRPEC was selected for MinION sequencing, conjugation assay, plasmid stability, and growth kinetics in vitro. The prevalence of MCRPEC was found to be 14.6% (98/673), with the highest prevalence in human rectal swabs (45.9% (45/98), p < 0.0001, odds ratio (OR): 0.125, 95% confidence interval (CI): 0.077–0.202). The percentages of MCRPEC from other samples were 14.3% (2/14) in dog feces, 12.0% (24/200) in flies, 11.0% (11/100) in chicken meat, 8.9% (8/90) in chicken cloacal, 8.0% (4/50) in chicken caeca, and 7.5% (4/53) in wastewater. MCRPEC was significantly more resistant to co-amoxiclav, sulfamethoxazoletrimethoprim, levofloxacin, ciprofloxacin, and gentamicin than MCRNEC (p < 0.05). Genomic analysis revealed the distribution of MCRPEC among diverse clonal types. The putative plasmid Inc types associated with mcr-1 were IncX4, IncHI2, IncP1, IncI2, and IncFIA, and those associated with mcr-3 were IncFII, IncFIA, IncFIB, IncP1, and IncR. Recovery of highly similar plasmids from both flies and other sampling sectors implied the role of flies in the dissemination of mcr-1. mcr-positive plasmids were shown to be conjugative, and a significantly high transfer rate into a hypervirulent clone ST1193 was observed. Plasmids containing mcr irrespective of Inc type were highly stable and invariably did not exert a fitness effect upon introduction into a new host. These findings signify the urgent need for a standard infection control program to radically decontaminate the source of resistance.
