BACKGROUND
Candidatus Neoehrlichia mikurensis is a newly emerging tick-borne bacterium from the family Anaplasmataceae. Its presence in Ixodes ricinus ticks was reported from various European countries, however, it's ecology and co-circulation with another member of the same family, Anaplasma phagocytophilum has not been rigorously studied yet.
FINDINGS
Candidatus N. mikurensis was detected in all sampling sites. In total, 4.5% of ticks were positive including larvae. The highest positivity was detected in Austria with a prevalence of 23.5%. The probability of Candidatus N. mikurensis occurrence increased with the proportion of ticks infected with Anaplasma phagocytophilum.
CONCLUSION
A positive association between the occurrences of Candidatus N. mikurensis and A. phagocytophilum indicates that both bacteria share similar ecology for their natural foci in Central Europe.
背景
“候选新立克次体”（Candidatus Neoehrlichia mikurensis）是一种从立克次体科中新兴的蜱传细菌。从各种欧洲国家的硬蜱（Ixodes ricinus）中报告了该菌的存在，然而，其生态学及其与同科的另一个成员（嗜吞噬细胞无形体，Anaplasma phagocytophilum）的共同循环尚未得到严格研究。
结果
在所有采样点均检测到候选新立克次体。总的来说，有 4.5%的蜱虫呈阳性，包括幼虫。在奥地利的阳性率最高，为 23.5%。候选新立克次体的出现概率随着感染嗜吞噬细胞无形体的蜱虫比例的增加而增加。
结论
候选新立克次体与嗜吞噬细胞无形体的发生之间存在正相关关系，表明这两种细菌在中欧的自然疫源地具有相似的生态学特征。
