原生动物犬肝孢子虫通过犬宿主摄入受感染的扁虱传播，并不是欧洲中纬度地区的地方性疾病。它的分布被认为与其主要扁虱媒介血吸虫的发生有关。在奥地利维也纳附近被发现的一只年轻的雄性金丝雀(Canis Aureus)被这种病原体感染。对扩增产物进行克隆和测序，发现犬嗜血杆菌有6种不同单倍型。根据这些序列，无法追踪到与感染来源的明确关系。这是奥地利首次报告犬疟原虫，目前发现的野狗等野犬可能是这种寄生虫自然传播到非流行地区的来源。这种野生动物的自然迁徙代表了一种病原体引进的方式，除了由于动物进出口而人为引入之外，在疾病预防中也必须考虑这种方式。(C)2012年爱思唯尔股份有限公司。版权所有。
The protozoan Hepatozoon canis, which is transmitted via ingestion of infected ticks by canine hosts, is not endemic to mid-latitude regions in Europe. Its distribution is supposed to be linked to the occurrence of its primary tick vector Rhipicephalus sanguineus. A young male golden jackal (Canis aureus) found as road kill close to Vienna, Austria, was infected by this pathogen. Cloning and sequencing of the PCR product revealed 6 different haplotypes of H. canis. Based on the sequences, no clear relationship to the origin of infection could be traced. This is the first report of H. canis for Austria, and wild canines such as the currently found jackal may provide a source of natural spread of this parasite into non-endemic areas. This natural immigration of wild animals represents a way of pathogen introduction, which has to be considered in disease prevention in addition to human-made introduction due to animal import and export.
