Abstract

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.

巴西犬犬埃利希体的分子特征：全球视角

本研究旨在对居住在巴西东南部未开发地区的狗的犬埃利希体种群进行分子表征，并研究从五大洲不同宿主获得的16S-rDNA序列的系统发育和单倍型关系。结果，鉴定出了两个犬种谱系，这可能对了解该物种的遗传多样性有重大贡献。在全球范围内的分析揭示了广泛的遗传多样性，在地方内和地方之间，以及宿主之间的差异，标志着该物种在全球范围内的进化关系的第一次全面探索。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
