Abstract

Investigated the distribution of microsporidia Nosema ceranae-the pathogen of so-called «Asian» Nosema disease in the apiaries of Ukraine. Investigated 784 samples of bee's podmore in a large extent affected by Nosemosis, that have been sent by beekeepers for research from 11 regions of Ukraine (Kyiv, Poltava, Vinnytsia, Chernihiv, Zhytomyr, Sumy, Zaporizhia, Donetsk, Volyn, Lviv, Khmelnytsky) in 2014-2016. Microsporidia Nosema ceranae was found in 74.5 % of the analyzed bee samples, i. e. on prevalence it dominated the microsporidia Nosema apis. Clinical signs and course of Nosema disease in bee families, where been found microsporidia Nosema ceranae, were classic, namely the weak development of families in the spring, in some families-the presence of traces of diarrhea.
