无形体属立克次体种类繁多,现已发现无形体属中的几个种对人类和动物致病。近年来,世界范围内新发及再发无形体病逐年上升,对人类和家畜健康造成重大威胁。为更好的了解病原体的保存和传播方式,国内外已对其宿主动物和传播媒介进行了大量的研究。本文就无形体属中确定的几个种的宿主动物和传播媒介作一综述。 Anaplasma is a wide range of rickettsia, and it has been found that several species of the anaplasma are pathogenic to humans and animals. In recent years, the worldwide incidence of new and recurrent aphakia has risen year by year, posing a significant threat to human and livestock health. To better understand how pathogens are stored and disseminated, a great deal of research has been conducted on their host animals and vectors at home and abroad. This article reviews several species of host animals and vectors identified in the Anaplasma.
