Objective: To investigate maternal-fetal transmission at human bocavirus (HBoV).
Methods: IgG antibody to HBoV in serum samples of 316 mothers were determined with ELISA and HBoV DNA was determined with real time PCR in the sera of the mothers and their infants.
Results: HBoV-IgG was positive in 40.20 percent (127/316) of the mothers, while it was positive in 29.43 percent (93/316) of the cord blood specimens of the infants. The difference between the two groups was significant (X2=8.12, P less than 0.005); 93 samples of both the mothers and the infants were positive for HBoV-IgG.
Conclusion: HBoV-IgG can cross the placenta to the fetuses through placenta. Further study is needed to answer the question whether vertical maternal-fetal transmission occurs.

Introduction: Group B Streptococcus (GBS) is an opportunistic pathogen that can induce chorioamnionitis (CA), increasing the risk of neurodevelopmental disorders (NDDs) in the offspring. The placenta facilitates maternal-fetal communication through the release of extracellular vesicles (EVs), which may carry inflammatory molecules such as interleukin (IL)-1. Although the role of EVs in immune modulation is well established, their specific characterization in the context of GBS-induced CA has not yet been investigated.

Oropouche virus (OROV) is an orthobunyavirus endemic in the Brazilian Amazon that has caused numerous outbreaks of febrile disease since its discovery in 1955. During 2024, Oropouche fever spread from the endemic regions of Brazil into non-endemic areas and other Latin American and Caribbean countries, resulting in 13,014 confirmed infections. Similarly to other orthobunyaviruses, OROV can undergo genetic reassortment events with itself as well as other viruses.

Background: Fecal lipocalin-2 (LCN2) is a biomarker of neutrophil activation, which is elevated in patients with inflammatory bowel disease (IBD); however, its dynamic changes during pregnancy and early life are largely unknown. We characterized LCN2 levels by maternal IBD diagnosis, offspring feeding behavior, and gut microbiota composition.
Methods: In the prospective MECONIUM (Exploring Mechanisms of Disease Transmission In Utero through the Microbiome) study, we analyzed 559 fecal samples from 91 pregnant women with IBD, 78 healthy controls, and their 147 offspring for LCN2 levels at each trimester of pregnancy and multiple time points during early life using linear mixed-effects model and multiple logistic regression analyses.

Background: DNA methylation plays a crucial role in mammalian development. While methylome changes acquired in the parental genomes are believed to be erased by epigenetic reprogramming, accumulating evidence suggests that methylome changes in sperm caused by environmental factors are involved in the disease phenotypes of the offspring. These findings imply that acquired sperm methylome changes are transferred to the embryo after epigenetic reprogramming.
