Increasing amount of data attest that (in the context of vector-borne infections) birds are not only important as hosts of blood-sucking arthropod vectors, but also as reservoirs of vector-borne pathogens. From 2015 to 2019 cadavers of 100 birds (from 45 species, nine orders) were collected in Hungary, and their organs were screened for DNA from a broad range of vector-borne bacteria with PCR and sequencing. Molecular analyses revealed the presence of Anaplasmataceae, and sequencing identified bacteria closely related to Neorickettsia helminthoeca and Ehrlichia chaffeensis in a Eurasian teal (Anas crecca) and a song thrush (Turdus philomelos), respectively. All samples were PCR negative for rickettsiae, borreliae, Francisella and Coxiella spp., as well as for piroplasms. To our knowledge, this is the first report of a Neorickettsia and an Ehrlichia sp., which belong to the phylogenetic groups of N. helminthoeca and E. chaffeensis, respectively, from Europe. The potential presence of these two vector-borne bacteria needs to be taken into account during future studies on the eco-epidemiology of Anaplasmataceae in Europe.

Anaplasmataceae与中欧，匈牙利鸟类中的Ehrlichia chaffeensis和Neorickettsia helminthoeca密切相关。

越来越多的数据证明（在媒介传播的感染中）鸟类不仅作为吸血节肢动物媒介的宿主，而且作为媒介传播的病原体的储存地，都非常重要。从2015年到2019年，在匈牙利收集了100只鸟类的尸体（来自45种，9个顺序），并通过PCR和测序从广泛的载体传播细菌中筛选了它们的器官中的DNA。分子分析揭示了无形纲科的存在，并测序鉴定出分别与欧亚水鸭（Anas crecca）和鹅口疮（Turdus philomelos）中新立克次氏菌和恰菲埃里希氏菌密切相关的细菌。所有样品的立克次氏体，疏螺旋体，弗朗西斯菌属和Coxiella属菌以及子质均为PCR阴性。据我们所知，这是新立克次体和埃里希氏菌属的第一份报道，它们分别来自欧洲的赫尔辛基猪笼草和查菲埃希菌。在欧洲关于无形纲科的生态流行病学的未来研究中，需要考虑这两种载体传播细菌的潜在存在。
