Сurrent state of Vairimorpha spp. infection cases and haplotype distribution across Eurasian countries

Abstract

Abstract Current state of Vairimorpha spp. infection cases in A. mellifera across Eurasia was characterized using electronic databases. Most of the study regions reported presence of mixed infection with Vairimorpha spp, excluding South-West and South-Central parts of Eurasia, where only V. ceranae was present. No reports were found in the North-East part of Eurasia. Additionally, the presence of Vairimorpha spp. Ptp3 amino acid local haplotypes in the Republic of Tatarstan, Russian Federation was examined. As a result, two local haplotypes of V. ceranae were found: the first one was identical to those from Netherlands and South Korea and the second one was a new haplotype, different from those isolated in Slovenia and Thailand. Two local haplotypes of V. apis were found in the local apiary of Republic of Tatarstan: first one was identical to those isolated in Slovenia, Spain and Turkey and the second one was a new haplotype, similar to above mentioned ones.
