Abstract：
Background: Ehrlichia canis is transmitted by ticks causing Canine monocytic ehrlichiosis, which is considered one of the most critical tickborne pathogens. Materials and Methods: This study aimed to identify by PCR technique E. canis in ticks associated with dogs from urban and rural homes in Nuevo Leon, Mexico. The study was conducted at 13 localities in eight municipalities from 2012 to 2021. Results: A total of 1873 ticks of three species were captured: Amblyomma tenellum, Dermacentor variabilis, and Rhipicephalus sanguineus s.l. The overall infection rate of E. canis in ticks was 59.12% (149/252). Of the 15 sequences, three haplotypes were identified. Conclusion: The urban transmission cycle of canine ehrlichiosis is demonstrated, where the potential vector is the tick R. sanguineus s.l.
摘要：
背景：犬埃里希体是通过蜱传播的，导致犬单核细胞埃里希体病，被认为是最关键的蜱传病原体之一。材料和方法：本研究旨在通过PCR技术鉴定与新莱昂市城市和农村家庭的狗相关的蜱中的E.canis，墨西哥。该研究于2012年至2021年在8个城市的13个地区进行。结果：共捕获了三个物种的1873个蜱：Dermacentorvariabilis,和血象phanuss.l.E.canis在蜱中的总感染率为59.12％（149/252）。在15个序列中，确定了三个单倍型。结论：证明了犬埃里希体病的城市传播周期，其中潜在向量是滴答R.sanguineuss.l.
