1. Clinical manifestations, laboratory findings, and histopathological characteristics observed in pregnant women with listeriosis during gestation. Additionally, data on potentially contaminated food items implicated during the symptomatic period, along with maternal age and gestational age at disease onset. 2. Diagnostic criteria and confirmed diagnoses of neonatal listeriosis, including anatomical sites from which *Listeria monocytogenes* was isolated, as well as clinical outcomes (e.g., survival, sequelae, or mortality). 3. In vitro pressure resistance profiles of *Listeria monocytogenes* strains isolated from clinical specimens of infected patients.
