Introduction
Nguyen Vinh Trung is a PhD student at the University of Amsterdam and Oxford University Clinical Research Unit (Vietnam). He received his MSc in Veterinary Science from Murdoch University (Australia) in 2010. His PhD was registered with the Academic Medical Center – University of Amsterdam (the Netherlands) on the project entitled “Antimicrobial drug resistance at the human-animal interface in Vietnam”. His area of interests is epidemiology and zoonotic diseases.

To understand the dynamics behind the worldwide spread of the mcr-1 gene, we determined the population structure of Escherichia coli and of mobile genetic elements (MGEs) carrying the mcr-1 gene. After a systematic review of the literature we included 65 E. coli whole genome sequences (WGS), adding 6 recently sequenced travel related isolates, and...

We investigated the consequences of colistin use in backyard chicken farms in Vietnam by examining the prevalence of mcr-1 in fecal samples from chickens and humans. Detection of mcr-1–carrying bacteria in chicken samples was associated with colistin use and detection in human samples with exposure to mcr-1–positive chickens.
Detailed materials and methods describing the selection and recruitment of study subjects, data collection, sample analyses, real-time PCR detection of the mcr-1 gene, adjustment of prevalence estimates, whole-genome sequencing analyses, and risk factor analyses. Univariate analyses of the risk factors associated with the presence of mcr-1–carrying...
Characteristics of mcr-1–positive Escherichia coli from chickens and farmers, Vietnam, 2012–2013.
Background:
Enteroaggregative (EAEC) and Shiga-toxin producing Escherichia coli (STEC) are a major cause of diarrhea worldwide. E. coli carrying both virulence factors characteristic for EAEC and STEC and producing extended-spectrum beta-lactamase caused severe and protracted disease during an outbreak of E. coli O104:H4 in Europe in 2011. We asse...
Antimicrobials are extensively used as growth promoters in animal feeds worldwide, but reliable estimates are lacking. We conducted an internet-based survey of commercial chicken and pig feed products officially approved for sale in Vietnam over the period March-June 2015. Information on the antimicrobial contents in feed products, alongside animal...
Salmonellosis is a public health concern in both the developed and developing countries. Although the majority of human non-typhoidal Salmonella enterica (NTS) cases are the result of foodborne infections or person-to-person transmission, NTS infections may also be acquired by environmental and occupational exposure to animals. While a considerable...
Importance statement:
Our study provides accurate baseline information on levels of antimicrobial use, as well as on the dynamics of phenotypic and genotypic resistance for antimicrobials of critical importance amongE. coliover the different stages of production in emerging pig and poultry production systems in Vietnam.E. coliisolates showed a hig...
In Vietnam, commercial disinfectants containing quaternary ammonium compounds (QACs) are commonly used in pig and poultry farms to maintain hygiene during production. We hypothesized that sustained exposure to sub-bactericidal concentrations of QAC-based disinfectants may result in increased levels of antimicrobial resistance (AMR) among Enterobact...
To describe the prevalence of antimicrobial resistance among commensal Escherichia coli isolates on household and small-scale chicken farms, common in southern Vietnam, and to investigate the association of antimicrobial resistance with farming practices and antimicrobial usage.
We collected data on farming and antimicrobial usage from 208 chicken...
In Mekong Delta farms (Vietnam), antimicrobials are extensively used, but limited data are available on levels of antimicrobial
resistance (AMR) among Escherichia coli isolates. We performed a structured survey of AMR in E. coli isolates (n = 434) from 90 pig, chicken, and duck farms. The results were compared with AMR among E. coli isolates (n = 2...
Antimicrobials are used extensively in chicken production in Vietnam, but to date no quantitative data are available. A 2012–2013 survey of 208 chicken farms in Tien Giang province, stratified by size (10–200 chickens; >200–2000), was carried out to describe and quantify the use of antibacterial antimicrobials (usage per week per chicken and usage...
