The effectiveness of breeding for inherent disease resistance in animals could be considerably increased by identifying the genes and mutations that cause diversity in disease resistance. One hundred and twenty adult female Baladi goats (sixty pneumonic and sixty apparently healthy) were used in this study. DNA and RNA were extracted from blood samples collected from the jugular vein of each goat. , , , , , , , , , , , , , , , and SNPs that have been previously found to be associated with pneumonia resistance/susceptibility were identified via PCR-DNA sequencing. The pneumonic and healthy goats differed significantly, according to a Chi-square analysis of the discovered SNPs. The mRNA levels of the studied immune markers were noticeably greater in the pneumonic goats than in the healthy ones. The findings could support the significance of the use of immune gene expression profiles and nucleotide variations as biomarkers for the susceptibility/resistance to pneumonia and provide a practical management technique for Baladi goats. These results also suggest a potential strategy for lowering pneumonia in goats by employing genetic markers linked to an animal's ability to fend off infection in selective breeding.
通过识别导致抗病性差异的基因和突变,动物固有抗病性育种的有效性可以得到显著提高。本研究使用了120只成年雌性巴拉迪山羊(60只患肺炎的和60只看似健康的)。从每只山羊颈静脉采集的血样中提取DNA和RNA。通过PCR-DNA测序鉴定了先前发现与肺炎抗性/易感性相关的、、、、、、、、、、、、、、、和单核苷酸多态性(SNP)。根据对发现的SNP进行的卡方分析,患肺炎的山羊和健康山羊有显著差异。在所研究的免疫标志物的mRNA水平上,患肺炎的山羊明显高于健康山羊。这些发现可以支持将免疫基因表达谱和核苷酸变异用作肺炎易感性/抗性生物标志物的重要性,并为巴拉迪山羊提供一种实用的管理技术。这些结果还表明了一种潜在策略,即通过在选择性育种中采用与动物抵御感染能力相关的遗传标记来降低山羊肺炎的发病率。
