Genital myasis is one of the most important diseases that affects the reproductive organs of Bactrian camels in which can cause serious mechanical damage to the vaginal tissue. The accumulation of bacteria in the vagina of female camels can affect their health and reproductive ability. The effect of this damage is commonly manifested in the vaginal flora and vaginal mucosal immune system. Therefore, this investigation is a study of the diversity of the vaginal flora and the differences between healthy Bactrian camels and those suffering from genital myiasis.
Vaginal microbiota samples were collected from two groups of female Bactrian camels of the same age. An Illumina MiSeq was used to sequence the 16S rRNA V3-V4 hypervariable sequence in the samples. The results showed that the vaginal microflora of the infected camels had a significantly greater operational taxonomic unit (OTU) value. According to the assessment of the alpha diversity index and the vaginal pH, the diversity index of the infected camel flora was higher than that of the normal camel flora, and the vaginal pH was lower than that of the normal camels (p < 0.01). There were no significant differences between the two groups in the abundance of dominant genera in the Bactrian camel vagina (P > 0.05), indicating that the certain stability is maintained.
Overall, this comparison revealed the differences and similarities between the vaginal microbiota of Bactrian camels in various health statues. In addition, these data provide a reference point for understanding the types of bacteria that cause genital myiasis affecting the healthy development of Bactrian camels.
生殖器蝇蛆病是影响双峰驼生殖器官的最重要疾病之一,可导致阴道组织严重机械损伤。雌性骆驼阴道内细菌的积累会影响它们的健康和生殖能力。这种损伤的影响通常表现在阴道菌群和阴道黏膜免疫系统上。因此,本研究旨在研究阴道菌群的多样性以及健康双峰驼和患有生殖器蝇蛆病的双峰驼之间的差异。
从两组年龄相同的雌性双峰驼中采集阴道微生物群样本。使用 Illumina MiSeq 对样本中的 16S rRNA V3-V4 高变区序列进行测序。结果表明,感染骆驼的阴道微生物菌群的操作分类单元(OTU)值显著更高。根据 alpha 多样性指数和阴道 pH 值评估,感染骆驼菌群的多样性指数高于正常骆驼菌群,阴道 pH 值低于正常骆驼(p<0.01)。两组骆驼阴道中优势属的丰度无显著差异(P>0.05),表明其具有一定的稳定性。
总体而言,本研究比较了不同健康状态下双峰驼阴道微生物群的差异和相似之处。此外,这些数据为了解引起生殖器蝇蛆病的细菌类型提供了参考,有助于促进双峰驼的健康发展。
