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

Nosema Apisin Drone Honeybees

Journal of Apicultural Research, 1972
SummaryDrone honeybees were found to be at least as susceptible as workers to infection by Nosema apis, and the median infective dose was fewer than 100 spores. Nevertheless proportionately many fewer drones than workers became infected in enzootically infected, undisturbed honeybee colonies.

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 ...

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

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.

Effect of Fumagillin upon Nosema apis (Zander)

Nature, 1953
A PRELIMINARY report by Katznelson and Jamieson1 on the effect of the antibiotic fumagillin (derived from an Aspergillus culture designated H–32) upon the infection of the adult honey bee by the microsporidian Nosema apis indicated promising results. They suggested that the action of the drug was prophylactic in nature, killing the infective amœboid ...

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

Nosema Apisand Dysentery of the Honeybee

Journal of Apicultural Research, 1967
SUMMARYSevere winter losses of honeybee colonies and poor growth or dwindling in spring were associated with dysentery. They were not caused simply by an enzootic infection with Nosema apis. Infection, although it is common, is usually slight in most colonies, and is spread by dysentery, but it is not the primary cause.
