概括
传染性马甲状炎 (CEM) 在冰岛完整的雄性中比 draft 和 Haflinger 马更为普遍. 非繁殖动物可能充当泰勒氏菌 (Taylorella equigenitalis) 的储存体,需要对冰岛马进行常规检测.
科学领域:
- 兽医科学 兽医科学 兽医科学
- 马的健康 马的健康
- 微生物学 微生物学
背景情况:
- 传染性马甲状炎 (CEM) 是一种由 Taylorella equigenitalis 引起的性病,影响马的生育能力.
- 在冰岛完整的雄性中感知到CEM病例的增加促使进一步调查.
- 由于检测和卫生协议,CEM可以导致暂时的不孕症和重大经济损失.
研究的目的:
- 为了调查泰勒罗拉equigenitalis在冰岛的完整的男性的流行.
- 为了比较T. equigenitalis在冰岛,草稿和Haflinger完整的雄性之间的流行情况.
- 为了测试T. equigenitalis在冰岛完整的男性中更高的流行率的假设.
主要方法:
- 进行了一项横截面研究,涉及来自38个农场的76只冰岛马,35只哈夫林格马和51只完好无损的拉马雄体的抽样.
- 量化聚合酶连锁反应 (qPCR) 用于T. equigenitalis检测.
- 统计分析包括费舍尔的精确测试和混合效应的后勤回归,分层动物的繁殖状态和年龄.
主要成果:
- 在研究的完整的男性中,T. equigenitalis的总流行率为16.7% (27/162).
- 冰岛的完整的雄性在T. equigenitalis阳性的几率明显高,相比于草稿和Haflinger雄性 (OR = 6.42,p = 0.02).
- 非繁殖动物的T.equigenitalis阳性概率明显低于活跃的繁殖动物 (OR = 0.09,p = 0.009).
结论:
- 冰岛的完整的雄性在T. equigenitalis的患病率较高,相比于龙头和Haflinger品种.
- 非繁殖马可以作为T.equigenitalis的储存库,突出其流行病学重要性.
- 建议在育种前对冰岛马进行常规CEM测试,并进一步研究疾病储库.

3.4K
A complete procedure of testing a hypothesis about a population mean when the population standard deviation is unknown is explained here.
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
