A Nosema ceranae isolate from the honeybee Apis mellifera

, 2007
Microsporidiosis (nosema disease) of the honeybee, Apis mellifera, has spread worldwide and caused heavy economic losses in apiculture. We obtained a spore isolate from worker ventriculi of A.

Immune priming of honey bees protects against a major microsporidian pathogen

Pest 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 ...

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

Insect 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 ...

Evaluation of the Effectiveness of Selected Treatments of Nosema Spp. Infection by the Hemocytometric Method and Duplex Pcr

Acta Veterinaria, 2016
Recent years have witnessed an increase in the mortality of honey bees in many regions of the world. The observed decrease in the bee population results from a combination of factors, and microsporidian parasites Nosema apis and N.

Animal medical systems from Apis to apes: history, recent advances and future perspectives

Biological Reviews, Volume 100, Issue 6, Page 2608-2624, December 2025.
ABSTRACTAnimal medical systems encompass a wide range of behaviours aimed at maintaining or improving health. It has become clear that these behaviours are not limited to animals treating themselves (self‐medication) but also include the treatment of group members, resulting in the adoption of the more inclusive term “animal medication”. Behaviour with

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

Environmental 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

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

Molecular 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 ...
