Listeriosis is a rare and severe foodborne infection caused by Listeria monocytogenes. It manifests as septicemia, neurolisteriosis, and maternal-fetal infection. In pregnancy, it may cause maternal fever, premature delivery, fetal loss, neonatal systemic and central nervous system infections. Maternal listeriosis is mostly reported during the 2nd and 3rd trimester of pregnancy, as sporadic cases or in the context of outbreaks. Strains belonging to clonal complexes 1, 4 and 6, referred to as hypervirulent, are the most associated to maternal-neonatal infections. Here we review the clinical, pathophysiological, and microbiological features of maternal-neonatal listeriosis.

母婴李斯特菌病。


李斯特菌病是一种罕见且严重的食源性感染，由单核细胞增生李斯特菌引起。表现为败血症、神经李斯特菌病和母胎感染。在怀孕期间，可能会导致产妇发烧、早产、流产、新生儿全身和中枢神经系统感染。孕产妇李斯特菌病主要发生在妊娠第二和第三个月，为散发病例或暴发病例。属于克隆复合体 1、4 和 6 的菌株（称为高毒力菌株）与母婴感染最相关。在这里，我们回顾母婴李斯特菌病的临床、病理生理学和微生物学特征。
