The Whole Genome Sequencing (WGS) provides the most comprehensive overview of a bacterial strain.The genome composition can be analyzed by using WGS variant identification techniques such as Single Nucleotide Polymorphisms (SNPs\/wgSNP<\/strong>) or whole genome MultiLocus Sequence Typing (wgMLST<\/strong>) to identifiying the virulome<\/strong>, resistome<\/strong> and antibioresistome.<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

wgMLST<\/strong> uses WGS datas (assembled or not) to complete MLST analysis on a genome extense scale. For each sample, locus presence is analyzed and, when present, allele variants are determined. For each locus, new sequences are assigned new consecutive allele numbers. wgMLST is progressively being advised for subtyping purposes at any taxonomic level. <\/strong>MultiLocus Sequence Typing data provides close-to-ultimate discriminatory power to differentiate isolated bacterial strains.<\/strong><\/p>\n

The wgSNP<\/strong> bioinformatic pipelines detects SNP variants by mapping the WGS reads to a reference sequence. This approach has been also demonstrated to be suitable for bacterial strain genotyping\/strain typing<\/strong>.<\/p>\n

Moreover WGS would give the opportunity from genomic data achievable to predict set of genes that contribute to the virulence of a bacterium even for resistome and antibioresistome map of bacterium<\/strong>.<\/p>\n

Bacterial WGS holds serious promise for enhancing pathogen diagnostics, as well as industrial, agricultural and environmental strain exploration<\/strong>. A variety of applications including comparative genomics (i.e. differentiations between strains, strain typing) can be evaluated through WGS.<\/p>\n

WGS has greatly transformed the field of epidemiology and is particularly useful for investigating outbreaks of foodborne diseases<\/strong>. WGS allows differentiation between outbreak and non-outbreak strains of foodborne pathogens by comparing their microbial genomes. It has been confirmed that strain typing foodborne pathogens by WGS gives superior resolution to existing subtyping methods such as pulsed-field gel electrophoresis (PFGE). WGS is now used as a method by the FDA and the CDC in the United States to characterize Salmonella and Listeria monocytogenes <\/em>food and clinical isolates.<\/p>\n

Agri-food chains are increasingly interested by these techniques to identify perfectly the contamination source and assess the risks associated with contaminating bacteria.<\/p>\n
