The present study aimed to perform molecular characterization of Ehrlichia canis populations in dogs residing in underexplored regions of southeastern Brazil, and to investigate the phylogenetic and haplotypic relationships of 16S-rDNA sequences obtained from hosts across five different continents. As a result, two lineages of E. canis were identified, with the potential to significantly contribute to the understanding of the genetic diversity of this species. The analyses in a global perspective revealed extensive genetic diversity both within and among localities, as well as variations among hosts, marking the first comprehensive exploration of the evolutionary relationships of this species on a global scale.
本研究旨在对巴西东南部未充分探索地区的犬只中犬埃立克体种群进行分子特征分析，并研究从五大洲宿主获得的16S - rDNA序列的系统发育和单倍型关系。结果，鉴定出了犬埃立克体的两个谱系，这可能对理解该物种的遗传多样性有显著贡献。从全球角度进行的分析揭示了不同地点内部和之间广泛的遗传多样性，以及宿主之间的差异，这标志着首次在全球范围内对该物种的进化关系进行全面探索。
