Researchers recently published a large-scale study based on almost 7,000 strains of Listeria monocytogenes — the bacterium responsible for human listeriosis, a severe foodborne infection. Through the integrative analysis of epidemiological, clinical and microbiological data, the researchers have revealed the highly diverse pathogenicity of isolates belonging to this bacterial species. Comparative genomics led them to discover new virulence factors, which were demonstrated experimentally as involved in cerebral and fetal-placental listeriosis.
