Extracts From Grapefruit (Citrus paradisi) Peel via Microwave-Assisted and Conventional Extractions: Evaluation of Nosema Infection and Toxicity in Honey Bees. [PDF]

open access: yesVet Med Sci
Conventional and microwave‐assisted extractions of grapefruit peels were optimized using response surface methodology (RSM) based on TPC, TFC, and antioxidant activity (DPPH). The phytochemical profiles of the two optimum extracts were characterized via HPLC before evaluating their acute and chronic toxicity, as well as their effects on honey bee (Apis

Immune priming of honey bees protects against a major microsporidian pathogen. [PDF]

open access: yesPest Manag Sci
We immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...

Unbiased RNA shotgun metagenomics in social and solitary wild bees detects associations with eukaryote parasites and new viruses [PDF]

open access: yes, 2016
The diversity of eukaryote organisms and viruses associated with wild bees remains poorly characterized in contrast to the well-documented pathosphere of the western honey bee, Apis mellifera.

The Effects of Nosema apis and Nosema ceranae Infection on Survival and Phenoloxidase Gene Expression in Galleria mellonella (Lepidoptera: Galleriidae) Compared to Apis mellifera

open access: yesInsects, 2021
The study aims to prove the possibility of colonization of N. apis and N. ceranae to the intestine of the greater wax moth, detect the differences of greater wax moth based on the presence of Nosema species and examine the effect of Nosema species on the

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

open access: yes, 2008
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.

Nosema Ceranae Interactions with Nosema apis and Black Queen Cell Virus [PDF]

open access: yesAgriculture, 2021
Nosema ceranae is a relatively new pathogen of the honeybee (Apis mellifera) and the course of type C nosemosis (the disease that it causes) is not entirely known. In order to better understand the course and the consequences of this disease, laboratory experiments were performed. They aimed to compare the course of N. ceranae infection with the course

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

open access: yesVeterinary 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.
