Amphitrophic Listeria monocytogenes causes one-third of invasive listeriosis yet remains undetected by clonal complex-based risk classification
The paper shows that a major fraction of invasive Listeria monocytogenes is misclassified by conventional clonal complex-based risk assessment and demonstrates that amphitrophic lineages, which combine virulence and persistence traits, constitute 31% of clinical isolates.
