Late-Onset Sepsis in a Premature Infant Mediated by Breast Milk: Mother-to-Infant Transmission of Group B Detected by Whole-Genome Sequencing.

Background: Late-onset group B (LOGBS) sepsis is a cause of infection and death in infants. Infected breast milk has been considered a source of neonatal GBS infection and invasive infection. However, mother-to-infant transmission of GBS detected by the high-resolution diagnostic method is rarely reported.

Genomic and Phenotypic Diversity of Causing Pregnancy-Associated Listeriosis from Zhejiang Province, China, 2016-2018.

Introduction: There are few investigations describing the pregnancy-associated listeriosis in China, and the molecular characteristics of causing such infections remain largely unknown. We aim to investigate the phenotypic and genomic profiles of pregnancy-associated isolates and their association with isolates recovered from human and non-human in China.

Materials And Methods: In this study, we conducted a 3-year surveillance of listeriosis in a women's hospital in Zhejiang province, using whole genome sequencing and bioinformatics tools.
