在过去的二十年里,细胞毒菌属。一直在征服欧亚大陆,尽管这一事实只是在帕拉斯猫发现C.manul之后,通过最近更深入的研究才被揭露出来。在欧洲,Cytauxzoon主要在南部国家发现,后来在中欧发现。这种病原体现已在俄罗斯首次发现(距莫斯科50公里),这是欧亚大陆最北部的一次目击。发现一名俘虏(Leptailurusserval)被感染。血液学分析显示白细胞和红细胞数量显著减少,以及血红蛋白浓度。遗传分析证实了细胞生长素的存在。在疾病期开始时的血液中。在同一繁殖中心的一只山猫中发现了相同的病原体。细胞生长素的其他两种单倍型。是从同一地点的家猫那里获得的,与来自意大利的样品相同。一种新的单倍型,这是第一次测序,在7/7调查的阿穆尔野猫中发现(100%)。这些病原体的高发生率和多样性表明,它们存在于俄罗斯的自由放养的家猫和野生猫科动物中,并可能被认为是对濒危物种的潜在威胁。目前的研究表明,这种病原体的遗传多样性可能比以前提出的还要高。需要进一步的遗传研究来描述这种病原体在欧亚大陆的多样性和系统发育。
Over the last two decades, Cytauxzoon spp. has been conquering Eurasia, although this fact has only been brought to light through recent more intensive research after the discovery of C. manul in Pallas\' cat. In Europe, Cytauxzoon was detected mainly in southern countries and later in central Europe. This pathogen has now been found in Russia for the first time (50 km from Moscow), this being the most northern sighting in Eurasia. A captive serval (Leptailurus serval) was found to be infected. Hematological analysis showed a crucial decrease in the number of leukocytes and erythrocytes, as well as in hemoglobin concentration. Genetic analysis confirmed the presence of Cytauxzoon spp. in serval blood at the beginning of the disease period. The identical pathogen was found in one bobcat at the same breeding center. Two other haplotypes of Cytauxzoon spp. were obtained from domestic cats at the same location, identical to the samples from Italy. One new haplotype, which was sequenced for the first time, was found in 7/7 investigated Amur wildcats (100%). The high occurrence and diversity of these pathogens suggest that they are present in free-ranging domestic cats and wild
felids in Russia, and may be considered a potential threat to the endangered species. Current research shows that the genetic diversity of this pathogen may be even higher than it was suggested previously. Further genetic research is necessary to describe the diversity and phylogeny of this pathogen in Eurasia.
