is a widely distributed opportunistic pathogenic bacterium that can infect livestock, wildlife, community animals, and humans, resulting in suppurative infection of tissue and organ mucosa, including pneumonia, liver abscessation, mastitis, metritis, endocarditis, and osteoarthritis. TP1804 and TP1808 were isolated from the uterine lavage fluid of cows with endometritis. This study analyzed the prokaryotic transcriptomics and proteomics of two strains of with similar growth curves but different cytotoxicity. Studying the metabolic mechanisms of these differentially expressed genes and proteins can greatly promote the discovery of new biomarkers and improve the accuracy of biomarker identification, which is of great value for molecular mechanisms, biomarkers, early diagnosis of diseases, molecular typing, and prognosis. Our results indicate that the control of the virulence by tRNAs to bacteria during ribosome biosynthesis is crucial.
是一种广泛分布的机会致病菌,可感染家畜、野生动物、群居动物和人类,导致组织和器官黏膜的化脓性感染,包括肺炎、肝脓肿、乳腺炎、子宫炎、心内膜炎和骨关节炎。TP1804和TP1808是从患有子宫内膜炎的奶牛子宫灌洗液中分离出来的。本研究分析了两株生长曲线相似但细胞毒性不同的该菌的原核转录组学和蛋白质组学。研究这些差异表达基因和蛋白质的代谢机制可极大地促进新生物标志物的发现并提高生物标志物鉴定的准确性,这对于分子机制、生物标志物、疾病早期诊断、分子分型和预后具有重要价值。我们的结果表明,在核糖体生物合成过程中,tRNA对细菌毒力的控制至关重要。
