Feline haemoplasma infection studies are lacking in Russia. This retrospective study was conducted to estimate the prevalence of feline haemoplasmas in domestic cats in the Moscow region, Russia. A risk of haemoplasma coinfection with feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) was also determined. qPCR analysis for feline haemoplasmas was performed on EDTA blood samples from 753 cats from the Moscow region, Russia. Subsets of these samples were tested also for FIV and FeLV by qPCR. Of the 753 blood samples, 104 (13.8 %) were positive for one of the Mycoplasma species. The prevalence of 'Candidatus Mycoplasma haemominutum' (CMhm), Mycoplasma haemofelis (Mhf), and 'Candidatus Mycoplasma turicensis' (CMt) was 7.6 %, 5.5 %, and 0.7 %, respectively. One sample (0.1 %) was simultaneously infected with two haemoplasmas, namely, Mhf and CMt. Haemoplasma positive cats were more likely to be infected with FIV than haemoplasma negative (17.6 % vs 6.7 %), but these differences were not statistically significant. The prevalence of FeLV was comparable among haemoplasma positive and negative cats (23.5 % vs 25.7 %) All three known species of feline haemoplasma were detected, confirming their presence in Russia. The overall and species-specific rates of haemoplasma infections in Russian cats are generally similar to the rates in the countries of central Europe. This report documents for the first time the prevalence of feline hemotropic mycoplasmas in domestic cats not only in Russia but also in eastern Europe.
俄罗斯的猫类血巴尔通体感染研究较为匮乏。本回顾性研究旨在评估俄罗斯莫斯科地区家养猫中猫类血巴尔通体的流行率，并确定其与猫白血病病毒（FeLV）和猫免疫缺陷病毒（FIV）的共感染风险。对来自俄罗斯莫斯科地区的 753 只猫的 EDTA 血液样本进行了 qPCR 分析，以检测猫类血巴尔通体。对这些样本的子集也进行了 qPCR 检测，以确定 FIV 和 FeLV 的感染情况。在 753 份血液样本中，有 104 份（13.8%）对一种支原体物种呈阳性。“类马支原体贫血亚种”（CMhm）、猫支原体（Mhf）和“土耳其支原体”（CMt）的流行率分别为 7.6%、5.5%和 0.7%。有 1 份样本（0.1%）同时感染了两种血巴尔通体，即 Mhf 和 CMt。感染血巴尔通体的猫比未感染的猫更有可能感染 FIV（17.6%比 6.7%），但这些差异无统计学意义。感染血巴尔通体的猫和未感染的猫之间 FeLV 的流行率相当（23.5%比 25.7%）。本研究共检测到三种已知的猫类血巴尔通体，证实了它们在俄罗斯的存在。俄罗斯猫类血巴尔通体的总体感染率和种特异性感染率与中欧国家的感染率相似。本报告首次记录了不仅在俄罗斯，而且在东欧地区的家养猫中存在猫类血巴尔通体感染的流行率。
