Bacterial communities in the reproductive tract of avian species play an important role in keeping birds healthy and encouraging growth. Infection can occur during egg formation with pathogens that can be transmitted to the embryo. In this study, we investigated the bacterial composition in the turkey reproductive tract using a taxa identification based on the amplicon sequence of the V3-V4 region of the 16S rRNA gene. The microbial composition and relative abundance of bacteria differed between individual birds. Among the 19 phyla detected in turkey oviduct were unique taxa like Planctomycetes or Petescibacteria. Differences in composition of bacterial diversity were found at the family and genus level. Oviducts contained also several genus with well-recognized avian pathogens like Escherichia-Shigella, Enterococcus, Staphylococcus, and Ornithobacterium. Some of the bacteria described in this study have not been so far identified in turkeys. The objective of this study was to identify bacterial communities in the turkey oviduct and compared the composition of the oviduct with that in chickens broadening the knowledge of the microbial composition in the reproductive tract of poultry.
禽类生殖道中的细菌群落对于保持鸟类健康和促进生长起着重要作用。病原体可能在蛋形成过程中感染，并传播给胚胎。在这项研究中，我们使用基于 16S rRNA 基因 V3-V4 区扩增子序列的分类鉴定方法，研究了火鸡生殖道中的细菌组成。个体鸟类之间的微生物组成和细菌相对丰度存在差异。在火鸡输卵管中检测到的 19 个门中，存在像浮霉菌门或 Petescibacteria 门这样的特有类群。在科和属水平上也发现了细菌多样性组成的差异。输卵管中还含有一些公认的禽类病原体，如大肠杆菌-志贺氏菌、肠球菌、葡萄球菌和鸟分枝杆菌。本研究中描述的一些细菌迄今尚未在火鸡中被识别。本研究的目的是鉴定火鸡输卵管中的细菌群落，并将输卵管的组成与鸡的组成进行比较，从而拓宽对家禽生殖道微生物组成的认识。
