RNA Interference-Mediated Knockdown of Genes Encoding Spore Wall Proteins Confers Protection against Nosema ceranae Infection in the European Honey Bee, Apis mellifera

open access: yesMicroorganisms, 2021
Nosema ceranae (Opisthosporidia: Microsporidia) is an emergent intracellular parasite of the European honey bee (Apis mellifera) and causes serious Nosema disease which has been associated with worldwide honey bee colony losses.

Immune priming of honey bees protects against a major microsporidian pathogen

open access: yesPest Management Science, Volume 81, Issue 12, Page 7939-7949, December 2025.
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 ...

Determination of Nosema Disease in Colonies of Kırşehir Province

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2017
The aim of the study was to determine the prevalence of Nosema disease caused by Nosema ceranae and Nosema apis in bee colonies in Kırşehir. A hundred worker honey bee samples were collected from each of 51 beekeepers in 31 locations in 5 provinces of ...

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

open access: yesInsect Science, Volume 32, Issue 6, Page 1911-1925, December 2025.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

A comprehensive transcriptome data of normal and Nosema ceranae-stressed midguts of Apis mellifera ligustica workers

open access: yesData in Brief, 2019
Honeybees are pivotal pollinators of crops and wild flora, and of great importance in supporting critical ecosystem balance. Nosema ceranae, a unicellular fungal parasite that infects midgut epithelial cells of honeybees, can dramatically reduce honeybee

Molecular Surveillance of Honey Bee Hives Using eDNA Metabarcoding During Pollination Season

open access: yesEnvironmental DNA, Volume 7, Issue 6, November–December 2025.
Healthy honey bees are critical in safeguarding our food supply, but monitoring their health may present a significant challenge. Here, we used environmental DNA (eDNA) metabarcoding on bee hive debris and detected species of arthropods, bacteria and fungi contributing to form the bee hive environment, including hive pests and pathogens as well as hive

Evaluation of Antimicrosporidian Activity of Plant Extracts on Nosema ceranae

open access: yesJournal of Apicultural Science, 2016
Nosemosis is one of the most common protozoan diseases of adult bees (Apis mellifera). Nosemosis is caused by two species of microsporidia; Nosema apis and Nosema ceranae.

How Population Structure and Nest Membership Shape Pathogen Patterns in Bumble Bees

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Host density, genetic diversity and social groups are key factors influencing pathogen transmission in wildlife populations, but their interactions remain poorly understood in insects. Islands can provide natural laboratories with distinct populations that vary in density and genetic diversity, whereby dense, genetically homogeneous ...

First Detection of Nosema Ceranae and Nosema Apis in Greater Wax Moth Galleria Mellonella

open access: yesJournal of Apicultural Science, 2017
The greater wax moth Galleria mellonella L. (Lepidoptera: Pyralidae), one of the pests of honey bee (Apis mellifera L.) colonies, has spread almost all over the world. Although the G.

The gut parasite Nosema ceranae impairs olfactory learning in bumblebees

open access: yesJournal of Experimental Biology, 2022
ABSTRACT Pollinators are exposed to numerous parasites and pathogens when foraging on flowers. These biological stressors may affect critical cognitive abilities required for foraging. Here, we tested whether exposure to Nosema ceranae, one of the most widespread parasites of honey bees also found in wild pollinators, impacts ...
