Although attempts to develop methods for the in vitro cultivation of microsporidia began as early as 1937, the interest in the culture of these organisms was confined mostly to microsporidia that infect insects. The successful cultivation in 1969 of Encephalitozoon cuniculi, a microsporidium of mammalian origin, and the subsequent identification of these organisms as agents of human disease hei...

In order to study the effects of Nosema ceranae infection on honey bee microRNA (miRNA) expression, we deep-sequenced honey bee miRNAs daily across a full 6-day parasite reproduction cycle. Seventeen miRNAs were differentially expressed in honey bees infected by N. ceranae that potentially target over 400 genes predicted to primarily involve ion binding, signaling, the nucleus, transmembrane tr...

Medonosna pčela (Apis mellifera L.) jedan je od najznačajnijih oprašivača. Međutim, klimatske promjene, uz bolesti koje uzrokuju stradanje pčela, prepoznate su kao osnovnih problema pčelarstva u budućnosti. Sušna ljeta i hladna proljeća, ukoliko pčelar ne intervenira, mogu dovesti do stradanja zajednica ili sporog proljetnog razvoja. U ovom istraživanju tijekom dvije sezone ispitan utjecaj stim...

A longitudinal study was carried out in order to evaluate Nosema spp. spore counts two key moments of the year (late autumn and spring) honeybee colonies from five eco-regions Argentina. Three hundred sixty were randomly selected infestation level Varroa destructor assessed spring 2015. In addition, a questionnaire concerning all management practices applied answered by beekeepers.
