Prevalence of the Microsporidian Nosema spp. in Honey Bee Populations (Apis mellifera) in Some Ecological Regions of North Asia

Veterinary Sciences, 2020
Two species of microsporidia, Nosema apis and Nosema ceranae, are obligate intracellular parasites that are widespread in the world and cause the infectious disease (Nosemosis) of the Western honey bee Apis mellifera.

Epidemiology of the Microsporidium Nosema ceranae in Four Mediterranean Countries. [PDF]

Insects, 2022
Nosema ceranae is a highly prevalent intracellular parasite of honey bees’ midgut worldwide. This Microsporidium was monitored during a long-term study to evaluate the infection at apiary and intra-colony levels in six apiaries in four Mediterranean countries (France, Israel, Portugal, and Spain).

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]

, 2013
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.

A miR-JL-5 inhibitor modulates the proliferation of <i>Nosema cerana</i>e in <i>Apis cerana</i>. [PDF]

Front Insect Sci
Background and aimsApis cerana is the native host of Nosema ceranae (N. ceranae). Previous studies reported that N. ceranae was more harmful to the new host (Apis mellifera) than the original host that had spread globally and become one of the factors implicated in honeybee colony collapses. Therefore, it was essential to study the relationship between

Targeting the honey bee gut parasite Nosema ceranae with siRNA positively affects gut bacteria

BMC Microbiology, 2020
Background Gut microbial communities can contribute positively and negatively to host health. So far, eight core bacterial taxonomic clusters have been reported in honey bees. These bacteria are involved in host metabolism and defenses. Nosema ceranae is

North American Propolis Extracts From Upstate New York Decrease Nosema ceranae (Microsporidia) Spore Levels in Honey Bees (Apis mellifera)

Frontiers in Microbiology, 2020
Nosema ceranae infections in honey bees (Apis mellifera) pose a severe threat to colony health. Beekeepers have used dicyclohexylammonium fumagillin to control Nosema apis, although it may be ineffective against N. ceranae. We investigated the ability of

Comparative Identification of MicroRNAs in Apis cerana cerana Workers’ Midguts in Response to Nosema ceranae Invasion [PDF]

Insects, 2019
Here, the expression profiles and differentially expressed miRNAs (DEmiRNAs) in the midguts of Apis cerana cerana workers at 7 d and 10 d post-inoculation (dpi) with N. ceranae were investigated via small RNA sequencing and bioinformatics. Five hundred and twenty nine (529) known miRNAs and 25 novel miRNAs were identified in this study, and the ...
