CHARACTERIZATION OF THE VAGINAL MICROBIOTA OF EWES AND COWS AND IDENTIFICATION OF THE MICROBIOTAS ROLE IN VAGINAL HEALTH, PREGNANCY OUTCOMES, AND NEONATAL HEALTH

We seek to examine the hypotheses that i) specific livestock vaginal communities increase or decrease the risks of acquisition of livestock venereal pathogens alike Brucella ovis, Campylobacter fetus, Helicobacter trogontum, or Arcobacter cryaerophilus; ii) that the vaginal microbiota are the first colonizers of neonatal animals and directly influence perinatal health and performance; iii) that specific vaginal microbial communities of cattle and sheep impact reproductive outcomes, including spontaneous abortion.

本研究旨在探讨以下假设：i) 特定的家畜阴道微生物群落会增加或降低类似布鲁氏菌（Brucella ovis）、胎儿弧菌（Campylobacter fetus）、胃螺杆菌（Helicobacter trogontum）或霜冻弧菌（Arcobacter cryaerophilus）等家畜性传播病原体的感染风险；ii) 阴道微生物群落是新生动物的首次定植者，并直接影响围产期健康与性能；iii) 特定的牛和羊阴道微生物群落会影响繁殖结果，包括自发性流产。
