Maternal_fetal virome contigs (clean)

clean vOTUs data from a maternal-fetal viral transmission study in sheep. The dataset includes samples from 6 ewes and 12 fetuses collected across multiple anatomical sites (maternal: oral cavity, rumen, ileum, vagina; fetal: placenta, umbilical cord blood, amniotic fluid, meconium) using sterile cesarean procedures. Samples underwent virus particle concentration and Illumina paired-end sequencing to investigate vertical viral transmission patterns. Rigorous contamination controls and negative controls were included.
