The current status of Nosema spp. infections in A. mellifera throughout Eurasia was characterized using electronic databases. Although N. ceranae was predominantly detected in southwestern and south-central regions and N. apis in northwestern and north-central areas, most studies reported the occurrence of both species in Eurasia. In addition, the occurrence of Nosema spp. and Ptp3 gene haplotypes was investigated in the Republic of Tatarstan, Russia. Most of the examined honey bees were infected with both N. apis and N. ceranae. N. apis and N. ceranae isolates were either heterozygous or belonged to different strains and showed infection with more than one strain. New haplotypes were found for N. apis and N. ceranae in the Republic of Tatarstan, Russia. This study expands the data regarding existing haplotypes of Nosema species: there are currently 9 shared and 56 unique Ptp3 nucleotide sequence haplotypes of N. ceranae, and 2 shared and 7 unique haplotypes of N. apis, respectively.
利用电子数据库描述了欧亚大陆蜜蜂中 Nosema 属感染的现状。尽管 N. ceranae 主要在西南和中南部地区检测到，N. apis 在西北和中北部地区检测到，但大多数研究报告称这两个物种在欧亚大陆都有发生。此外，还在俄罗斯鞑靼斯坦共和国调查了 Nosema 属和 Ptp3 基因单倍型的发生情况。大多数检查的蜜蜂都感染了 N. apis 和 N. ceranae。N. apis 和 N. ceranae 分离株要么是杂合的，要么属于不同的菌株，并感染了一种以上的菌株。在俄罗斯鞑靼斯坦共和国发现了 N. apis 和 N. ceranae 的新单倍型。本研究扩展了有关 Nosema 种现有单倍型的数据：目前有 9 个共享和 56 个独特的 N. ceranae Ptp3 核苷酸序列单倍型，以及 2 个共享和 7 个独特的 N. apis 单倍型。
