The degree of contamination of retail meat with colistin-resistant bacteria and its potential contribution to dissemination within communities remains to be determined. Thus, we aimed to elucidate the contamination status of colistin-resistance genes, indicative of colistin-resistant bacteria, in retail meats in Vietnam. In total, 46 chicken and 49 pork meats from stores in Vietnam and Japan were examined.

Although the mechanism of the spread of colistin-resistant bacteria in communities is unknown, geographic and regional characteristics may influence it. To elucidate the spread mechanism of colistin-resistant bacteria, we analyzed the genomes of colistin-resistant Escherichia coli isolated from Vietnam and Ecuador residents, which are geographically and socially different.

The horizontal gene transfer of the mobile colistin resistance gene via plasmids is thought to be one of the main mechanisms for dissemination. However, genotypic evidence to prove this in community settings is limited.

This study aimed to assess the phenotypic and genotypic antimicrobial susceptibility patterns of the group (BFG) isolated from healthy individuals in Vietnam and Japan in order to elucidate the prevalence of antimicrobial resistance in human flora in the two economically and geographically different countries.
Materials And Methods: BFG was isolated from fecal samples of 80 healthy individuals in Vietnam (n=51) and Japan (n=29).
The spread of drug-resistant bacteria via food has contributed to the dissemination of resistant bacteria among humans. However, the status of food contamination with resistant bacteria, particularly the quantitative level of resistant bacteria in food, has not yet been well elucidated. In this study, the abundance of colistin-resistant in meat samples was quantified to understand the origin of the contamination of meat available in local Vietnamese markets.

Methods: Genome sequences were determined using MiSeq and MinION platforms. Genome assembly was performed using Platanus Assembler v.
The wide distribution of colistin-resistant bacteria in developing countries has become a common phenomenon. To understand the mechanisms underlying their distribution, we studied the genetic background of colistin-resistant isolates from the fecal microbiota of healthy human residents from a community in Vietnam with a high prevalence of colistin-resistant with Fifty-seven colistin-resistant isolates were obtained from 98 residents; one isolate was collected from each individual and analyzed for We found that 36.8% of the isolates carried chromosomal Further, 63.

Purpose: The dissemination of colistin-resistant bacteria harboring the colistin-resistance gene in developing countries has recently entered the spotlight as an emerging public health threat, which is attributed to the abuse of colistin use in these countries. However, the prevalence of these bacteria in developing countries has not been extensively investigated. Therefore, in the present study, we examined the prevalence of cefotaxime-resistant commensal harboring among residents of a representative Vietnamese village and assessed the characteristics of these isolates.
