Introduction Numerous factors are known to influence reproductive efficiency in ewes, but few studies have investigated the potential role of vaginal microbiota sheep success. The objective this study was thoroughly characterize ewe throughout course pregnancy. Methods Vaginal samples were collected from 31 pregnant Hampshire and X Suffolk crossbred ewes on a weekly basis pre-breeding pregnancy testing then biweekly until just after lambing. To microbial communities, DNA extracted 16S rRNA...
Investigating the livestock vaginal microbiota is of increasing interest due to its relationship with animal reproductive performance. Recent publications have uncovered a high degree variability microbiota, making it difficult focus functional research on individual microorganisms. To address this variability, we conducted combined analysis publicly available 16S rRNA gene amplicon sequencing datasets reveal core in cattle, sheep, and pigs. The goal was identify bacterial genera that were...
Little is known regarding the vaginal microbiota of sheep that undergo spontaneous abortions. The aim this pilot study was to characterize, using 16S rRNA gene sequencing and shotgun metagenomics, throughout gestation two ewes (Ewe1 Ewe2) spontaneously aborted. Ewe1’s contained high abundances Histophilus, Staphylococcus, Unclassified Pasteurellaceae. Most notable abundance Campylobacter in following abortion. Ewe2’s characterized by Pasteurella gestation. Shotgun metagenomic produced...
