Ehrlichia chaffeensis is a small, gram negative, obligately intracellular bacterium that preferentially infects mononuclear phagocytes. It is the etiologic agent of human monocytotropic ehrlichiosis (HME), an emerging life-threatening tick-borne zoonosis. Mechanisms by which E. chaffeensis establishes intracellular infection, and avoids host defenses are not well understood, but involve functionally relevant host-pathogen interactions associated with tandem and ankyrin repeat effector proteins. In this review, we discuss the recent advances in our understanding of the molecular and cellular mechanisms that underlie Ehrlichia host cellular reprogramming strategies that enable intracellular survival.
查菲埃立克体是一种小型革兰氏阴性专性细胞内细菌，优先感染单核吞噬细胞。它是人类单核细胞埃立克体病（HME）的病原体，HME是一种新出现的、危及生命的蜱传人畜共患病。查菲埃立克体建立细胞内感染并逃避宿主防御的机制尚未完全了解，但涉及与串联和锚蛋白重复效应蛋白相关的功能相关的宿主-病原体相互作用。在这篇综述中，我们讨论了我们对埃立克体宿主细胞重编程策略背后的分子和细胞机制的最新理解进展，这些策略使细胞内生存成为可能。
