Resistome and comparative genomics of clinical isolates of diarrheagenic Escherichia coli from Lima, Peru. Ronnie G. Bacterial resistance is a major global health problem associated with increased loss of economic productivity and human mortality. Approximately 23, people die annually in the United States due to infections caused by bacteria resistant to antibiotics 1e.

The group of E. According to their pathogenesis, this group is classified into seven pathotypes: Enteropathogenic E. Most studies focus on the phenotypic detection of extended spectrum beta-lactamases ESBL and quinolone resistance, however, in recent years the study of resistance genes has been carried out by using molecular methods, such as PCR and Sanger sequencing 4.

In recent years, the use of whole genome sequencing has been employed to characterize virulence genes of different DECs and to identify phylogenetic relationships between pathotypes 5. Since this aspect has been little explored in Peru, the aim of this research is to describe the characteristics of the resistome and comparative genomics of different DECs from the city of Lima. Motivation for the study: There has been an increase in gastrointestinal infections by antibiotic-resistant diarrheagenic Escherichia coli DEC in recent years, whose genomic characterization has been scarcely researched in Peru.

Main findings: The pathotypes of DEC from How are genes identified, Peru, with determinants of resistance to beta-lactams and quinolones are diverse, iedntified molecularly and phylogenetically. Implications: Genome sequencing allows a deep understanding of the continuous changes and adaptations that pathogens like DEC undergo, so its implementation would be important for the surveillance how to find the relationship in a scatter plot antimicrobial resistance in Peru.

We worked on 14 E. The selection criteria were based on the antimicrobial sensitivity profile by diffusion disc previously evaluated by the laboratory Appendix 1. Confirmation of E. The pathotypes were characterized based on primers according to Appendix 2. We evaluated the quality of the sequences using FastQC v0. Adapters and low-quality nitrogenous bases were removed with Trimmomatic v0. The sequences were assembled de novo using A5-miseq pipeline 7. Gnes used Kraken for gender identification and removal of contaminated contigs 8.

The assignment of clone complexes and the creation of a minimum spanning tree MST was carried out using BioNumerics v7. Prediction of coding sequences was made using the program Prodigal v2. For the detection of antibiotic resistance genes, we used online database CARD 10which includes chromosomal and plasmid how are genes identified. For comparative genomics, genomes assembled with Prokka v1. The annotation results were uploaded genrs the BPGA v1.

As a final step, the resulting matrix of pathotype annotation was used for inter-group comparative analysis using VennPainter All xre isolates were reconfirmed as E. Table 1 Genomic data of diarrheagenic Escherichia coli isolates in Lima, Peru. The sequencing error rate of 0. The fourteen genomes sequenced had an average of high quality contigs. Each genome was tenes as E. Figure 2 Minimum gejes tree of 14 allelic profiles of the multilocus sequence typing MLST arf the diarrheagenic Escherichia coli included in this study, according to Achtman and designed with the BioNumerics how are genes identified.

During the resistome analysis we detected genes encoding beta-lactamases: nine genomes presented the ampC gene; four presented bla TEM1, and only one presented bla CTX-M How are genes identified addition, genes related to resistance to quinolones were detected. The average number of coding sequences for the fourteen genomes analyzed was 5, The number of genes in the accessory genome varied between and what is a food web in simple words, while the number of unique genes varied between 0 and Finally, the number of genes in the central genome was 2, Table 1.

Pan-genomic functional analysis detected 2. In addition, annotation using the database of Clusters of Orthologous Groups of proteins COGs categories detected that 5. Comparative genomics between pathotypes revealed 2, genes from the central genome. Additional data on the grouping of ideentified or three pathotypes are detailed in Figure how are genes identified. Figure genrs Comparative genomics of Escherichia coli pathotypes. The central intersection indicates the genes shared by the four pathotypes central genome.

Diarrheagenic E. It is important to report the genomic characteristics of pathogenic isolates to understand bacterial resistance and pathogenesis features that will contribute to monitoring and implementation of new policies related to meaning of dictionary in nepali public health. In this study, nine E. On the contrary, the detection of ampC -type beta-lactamase is how are genes identified explored in our region, and usually only a low-frequency is phenotypically detected Quinolone resistance has how are genes identified been reported in Peru, including commensal strains due to the strong influence of persistent exposure to these antimicrobials 17 ; however, few studies focused on the use of molecular markers to determine quinolone resistance.

Furthermore, genomic sequencing has led to the discovery of additional genes related to resistance to what to write in tinder profile antibiotics. The analysis of the relationship between pathotypes non-taxonomic and phylogroups taxonomic of E. On the other hand, the ETCEs are mostly from the A and D phylogroups 19the seven isolates evaluated were also from this phylogroups.

In contrast, the EHECs were the most consistent group and were only associated with phylogroup E, and there is an evolutive explanation: the predominant serotype in this how are genes identified, O H7, derives from the gene acquisition of a non-pathogenic isolate O H7, called preEHEC Pan-genomic analysis of diarrheagenic E. Although the previous analysis only showed information regarding 14 genes associated with idenyified, we were able to ientified additional resistance-associated genes among mutations and other effectors ; however, due to the little information available regarding these gnees in E.

The latter result is interesting, since it contrasts with the work done by Hazen et al. On the contrary, most comparative genome studies are only based on the analysis of differences and similarities within the same pathotypes, so our research offers a first look at comparative genomes between different pathotypes and is one of the first studies on this subject in Peru. In conclusion, the isolates of diarrheagenic E.

We detected pathotypes, ST and phylogroups with molecular and phylogenetic diversity. We suggest to continue monitoring the antimicrobial resistance of these bacteria with modern sequencing techniques, since this information is useful for local public health. Antimicrobial Resistance.
