Distribution and transmission of American foulbrood in honey bees [PDF]

, 2006
The distribution of Paenibacillus larvae spores, the causative agent of American foulbrood, was studied on three different levels in the honey bee system; the apiary level, the colony level and the individual honey bee level.

Honey Bee Colony Health in Thiamethoxam‐Treated Sugar Beet Fields: A Field‐Based Case Study

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Using multi‐site field trials during Germany's 2021 emergency authorization of thiamethoxam‐treated sugar beet, we combined colony demography and residue analyses with complementary worker survival assays to characterize honey bee exposure under realistic conditions.

Development and validation of a novel field test kit for European foulbrood [PDF]

Apidologie, 2008
European foulbrood (EFB) is a serious and widespread disease of honey bee larvae. It is a notifiable disease in the United Kingdom under existing legislation, so colonies must be officially screened for signs of disease. The current study developed a rapid and sensitive test to diagnose EFB in the field.

Honey Bee Pathogen Prevalence and Interactions within the Marmara Region of Turkey

Veterinary Sciences, 2022
Beekeeping has yet to reach its full potential in terms of productivity in Turkey where it has a relatively large role in the economy. Poor colony health is suspected to be the reason for this, but comprehensive disease monitoring programs are lacking to

Integrative Genomics Reveals the Genetics and Evolution of the Honey Bee’s Social Immune System [PDF]

, 2019
Social organisms combat pathogens through individual innate immune responses or through social immunity—behaviors among individuals that limit pathogen transmission within groups.

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

Synthesis, Characterization and in Vitro Antibacterial Activities of CdO Nanoparticle and Nano-sheet Mixed-ligand of Cadmium(ІІ) Complex [PDF]

Nanochemistry Research, 2016
Here, we report the synthesis of a Schiff-base mixed-ligand complex of cadmium(ІІ) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. The complex formula is [Cd(3-bpdh)(3-bpdb)Cl2]n (1), where the ligands are 3-bpdh = 2,

Landscape‐Wide Metabarcoding Shows Interactions Among the Gut Microbiome and Pollen Diversity in the Invasive Bumblebee, Bombus terrestris

Ecology and Evolution, Volume 15, Issue 7, July 2025.
The study examines how environmental factors and dietary diversity influence the gut microbiome of the invasive European buff‐tailed bumblebee (Bombus terrestris) in Tasmania. We found that gut bacterial composition and diversity were significantly affected by annual precipitation, pasture percentage, temperature and interactions between pollen ...
