Contamination with food-borne pathogens, such as Listeria monocytogenes, remains a big concern for food safety. Hence, rigorous and continuous microbial surveillance is standard procedure. At this point, however, the industry authorities only focus on detection of monocytogenes without characterization individual strains into groups more or less concern. As whole genome sequencing (WGS) gains increasing interest in industry, methodology presents an opportunity to obtain finer resolution traits virulence. Within study, we therefore aimed explore use WGS combination Machine Learning (ML) predict L. virulence potential sub-species level.

Genome-wide association studies (GWASs) have the potential to reveal genetics of microbial phenotypes such as antibiotic resistance and virulence. Capitalizing on growing wealth bacterial sequence data, GWAS methods aim identify causal genetic variants while ignoring spurious associations. Bacteria reproduce clonally, leading strong population structure genome-wide linkage, making it challenging separate true ‘hits’ (i.e. mutations that cause a phenotype) from non-causal linked mutations. attempt correct for in different ways, but their performance has not yet been systematically comprehensively evaluated under range evolutionary scenarios. Here, we developed simulator (BacGWASim) generate genomes with varying rates mutation, recombination other parameters, along subset underlying phenotype interest. We assessed (recall precision) three widely used single-locus approaches (cluster-based, dimensionality-reduction linear mixed models, implemented plink , pyseer gemma ) one relatively new multi-locus model pyseer, across simulated sample sizes, mutation effect sizes.

Abstract The emergence of resistance to azithromycin complicates treatment Neisseria gonorrhoeae , the etiologic agent gonorrhea. Substantial remains unexplained after accounting for known mutations. Bacterial genome-wide association studies (GWAS) can identify novel genes but must control genetic confounders while maintaining power. Here, we show that compared single-locus GWAS, conducting GWAS conditioned on mutations reduces number false positives and identifies a G70D mutation in RplD 50S ribosomal protein L4 as significantly associated with increased ( p -value = 1.08 × 10 −11 ). We experimentally confirm our results demonstrate other macrolide binding site are prevalent (present 5.42% 4850 isolates) widespread (identified 21/65 countries across two decades).
