概括

马匹白病会导致无声的生殖问题,包括胎盘异常和堕胎. 这项研究发现,在有这些生殖问题的马匹中,50%的马匹感染了Leptospira interrogans.

科学领域:

兽医科学兽医科学兽医科学
生殖医学生殖医学
微生物学微生物学

背景情况:

马匹白病是被忽视的生殖功能衰竭的原因.
它通常呈现为一种沉默的慢性综合征,导致堕胎,死产和弱小的小.

研究的目的:

为了调查与Leptospira interrogans感染有关的胎盘异常的发生,在自然感染的马匹中调查.
评估在表现出生殖问题的马匹中Leptospira interrogans的流行率.

主要方法:

选择了10只怀孕的母马,超声波显示有胎盘异常的证据.
收集的血清用于血清学和宫性阴道粘液 (CVM) 用于PCR.
在CVM样本上进行了lipL32PCR,然后对阳性病例进行secY基因测序.

主要成果:

50% (5/10) 的马匹在CVM中通过lipL32PCR检测出Leptospira interrogans的阳性.
所有已识别的Leptospira菌株都被证实为Leptospira interrogans.
这些发现表明,Leptospira interrogans和胎盘异常之间存在显著的关联.

结论:

胎盘异常是亚临床马匹白螺旋症的一个关键特征.
兽医应该考虑在马匹生殖健康管理中进行白螺杆菌检测.
早期检测和治疗白病可以改善马匹的生殖结果.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
