Poult Sci 2021; 100:101370. [PMID: 34332223 PMCID: PMC8339308 DOI: 10.1016/j.psj.2021.101370] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/25/2021] [Accepted: 06/25/2021] [Indexed: 11/05/2022] Open
Abstract
The extended-spectrum cephalosporin resistant E. coli from food animals transferring to community settings of humans causes a serious threat to public health. Unlike phylogroup B2 E. coli strains, the clinical significance of isolates in phylogroup F is not well revealed. Here, we report on a collection (n = 563) of phylogroup F E. coli isolates recovered from chicken colibacillosis tissues and retail raw chicken meat samples in Eastern China. There was an overlapped distribution of MLST types between chicken colibacillosis-origin and meat-source phylogroup F E. coli, including dominant STs (ST648, ST405, ST457, ST393, ST1158, etc). This study further investigated the presence of extended-spectrum β-lactamase (ESBL/pAmpC) producers in these chicken-source phylogroup F E. coli strains. The prevalence of extended-spectrum cephalosporin resistant strains in phylogroup F E. coli from chicken colibacillosis and raw meat separately accounted for 66.1 and 71.2%. The resistance genotypes and plasmid replicon types of chicken-source phylogroup F E. coli isolates were characterized by multiplex PCR. Our results revealed β-lactamase CTX-M, OXA, CMY and TEM genes were widespread in chicken-source phylogroup F E. coli, and blaCTX-M was the most predominant ESBL gene. Moreover, there was a high prevalence of non-lactamase resistance genes in these β-lactam-resistant isolates. The replicons IncB/O/K/Z, IncI1, IncN, IncFIC, IncQ1, IncX4, IncY, and p0111, associated with antibiotic-resistant large plasmids, were widespread in chicken-source phylogroup F E. coli. There was no obvious difference for the populations, resistance spectrums, and resistance genotypes between phylogroup F E. coli from chicken colibacillosis tissues and retail meats. This detail assessment of the population and resistance genotype showed chicken-source phylogroup F E. coli might hold zoonotic risk and contribute the spread of multidrug-resistant E. coli to humans.

Abstract
BACKGROUND The devolution of health to Scotland in 1999, led for the first time in the NHS, to different priorities and success indicators for infection prevention and control (IPC). This project sought to understand, compare and evaluate the national IPC priorities and available indicators of success. AIM To identify the national IPC priorities alongside national indicators of success. METHODS Critical analysis of nationally produced documents and publicly available infection-related data up to March 2018. FINDINGS For both NHS Scotland and England the local and national IPC priorities are evidenced by: (1) people being cared for in an IPC-safe environment; (2) staff following IPC-safe procedures; and (3) organisations continuously striving not just to attain standards, but to improve on them. If national agencies that produce data were also charged with using a Continuous Quality Improvement (CQI) model, then there would be further opportunities to detect and improve on successes.

Chicken-source Escherichia coli within phylogroup F shares virulence genotypes and is closely related to extraintestinal pathogenic E. coli causing human infections. Transbound Emerg Dis 2020; 68:880-895. [PMID: 32722875 DOI: 10.1111/tbed.13755] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 07/15/2020] [Accepted: 07/20/2020] [Indexed: 02/06/2023]
Abstract
ExPEC is an important pathogen that causes diverse infection in the human extraintestinal sites. Although avian-source phylogroup F Escherichia coli isolates hold a high level of virulence traits, few studies have systematically assessed the pathogenicity and zoonotic potential of E. coli isolates within phylogroup F. A total of 1,332 E. coli strains were recovered from chicken colibacillosis in China from 2012 to 2017. About 21.7% of chicken-source E. coli isolates were presented in phylogroup F. We characterized phylogroup F E. coli isolates both genotypically and phenotypically. There was a widespread prevalence of ExPEC virulence-related genes among chicken-source E. coli isolates within phylogroup F. ColV/BM plasmid-related genes (i.e. hlyF, mig-14p, ompTp, iutA and tsh) occurred in the nearly 65% of phylogroup F E. coli isolates. Population structure of chicken-source E. coli isolates within phylogroup F was revealed and contained several dominant STs (such as ST59, ST354, ST362, ST405, ST457 and ST648). Most chicken-source phylogroup F E. coli held the property to produce biofilm and exhibited strongly swimming and swarming motilities. Our result showed that the complement resistance of phylogroup F E. coli isolates was closely associated with its virulence genotype. Our research further demonstrated the zoonotic potential of chicken-source phylogroup F E. coli isolates. The phylogroup F E. coli isolates were able to cause multiple diseases in animal models of avian colibacillosis and human infections (sepsis, meningitis and UTI). The chicken-source phylogroup F isolates, especially dominant ST types, might be recognized as a high-risk food-borne pathogen. This was the first study to identify that chicken-source E. coli isolates within phylogroup F were associated with human ExPEC pathotypes and exhibited zoonotic potential.

Avian-source mcr-1-positive Escherichia coli is phylogenetically diverse and shares virulence characteristics with E. coli causing human extra-intestinal infections. Vet Microbiol 2019; 239:108483. [PMID: 31699469 DOI: 10.1016/j.vetmic.2019.108483] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2019] [Revised: 10/24/2019] [Accepted: 10/24/2019] [Indexed: 12/30/2022]
Abstract
Colisepticemia caused by bloodstream infection of the extraintestinal pathogenic Escherichia coli (ExPEC) has become a serious public health problem. The recent emergence of the colistin-resistant Enterobacteriaceae, especially mcr-1-positive E. coli (MCRPEC) exerts great concern around the world. The molecular epidemiology and zoonosis risk of avian-origin MCRPEC are reported to be substantially lower. Here, we presented a system-wide analysis of emerging trends and zoonotic risk of MCRPEC recovered from avian colibacillosis in China. Our results showed the majority of avian-source MCRPEC isolates were classified as ExPECs. We also found that not only MCRPEC in phylogroups B2 and D, but also several E. coli populations in groups B1 and F possessed high virulence in the two models of avian colibacillosis and three rodent models for ExPEC-associated human infections. The high-virulent MCRPEC clones belong to ST131, as well as ST-types (such as ST48, ST117, ST162, ST501, ST648, and ST2085). Our data suggested the zoonotic risk of MCRPEC appeared to be a close association with ColV/ColBM type virulence plasmids. A comprehensive genomic analysis showed the overlapped of ColV/ColBM plasmids contents between MCRPEC isolates from humans and poultry. Identification of ColV/ColBM plasmids among human MCRPEC isolates revealed the potential transmission of avian-source mcr-1-positive ExPECs to humans. Moreover, the presence of ColV/ColBM plasmid-encoded virulence determinants, could be used as a predictive label for pathogenic MCRPEC. These findings highlighted avian-origin MCRPEC isolates could be recognized as a foodborne pathogen.
