Pulmonary arterial hypertension during pregnancy is associated with increased maternal mortality and adverse fetal outcomes. The present study aimed to investigate differences in the initial meconium microbiota between neonates born to mothers with congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH) and those born to mothers with congenital heart disease (CHD) alone, thereby elucidating the potential influence of pulmonary arterial hypertension on the establishment of the early-life gut microbiome.MethodsWe collected first-pass meconium samples from neonates in the pulmonary hypertension group (PH group, n = 23) and the control group without pulmonary hypertension (NC group, n = 17) and characterized microbial profiles using 16S rRNA sequencing.ResultsThe PH group showed lower alpha diversity, with reduced Shannon and observed features indices (both P < 0.05), whereas Bray–Curtis beta diversity showed substantial overlap between groups. At the phylum level, the overall gut microbial structure was broadly comparable between the PH and NC groups, with no statistically significant differences in the relative abundance of dominant taxa. At the genus level, the mean relative abundance of Streptococcus was significantly lower in the PH group than in the NC group (0.20% vs. 2.09%, P = 0.0072). Predicted functional profiling suggested potential differences in dominant metabolic pathways between groups, including enrichment of ubiquinone biosynthesis and aromatic amino acid/chorismate biosynthesis pathways in the PH group.ConclusionCollectively, these findings extend current evidence on PAH-related alterations in early-life microbial ecosystems and provide a plausible microbiome-based basis for investigating the biological mechanisms underlying adverse maternal–fetal outcomes associated with pulmonary arterial hypertension.]]> https://www.frontiersin.org/articles/10.3389/frmbi.2026.1774429 https://www.frontiersin.org/articles/10.3389/frmbi.2026.1774429 <![CDATA[The interplay between bile acid metabolism and gut microbiome in biliary tract cancers]]> 2026-05-28T00:00:00Z Review Ifeoma IkeFarzad TeymouriChristiana CrookSofia GuzmanMax HazeltineDani CastilloDaneng LiGagandeep Brar https://www.frontiersin.org/articles/10.3389/frmbi.2026.1808609 https://www.frontiersin.org/articles/10.3389/frmbi.2026.1808609 <![CDATA[Soil microbial communities shift in response to cropping sequence diversification with perennial seed crops]]> 2026-05-26T00:00:00Z Original Research Newton Z.
