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,

Ecology and Pathogenicity for Honey Bee Brood of Recently Described Paenibacillus melissococcoides and Comparison With Paenibacillus dendritiformis, Paenibacillus thiaminolyticus

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
ABSTRACT Honey bee colonies contain thousands of individuals living in close proximity in a thermally homeostatic nest, creating ideal conditions for the thriving of numerous pathogens. Among the bacterial pathogens, Paenibacillus larvae infects larvae via the nutritive jelly that adult workers feed them, causing the highly contagious American ...

Peritrophic matrix-degrading proteins are dispensable virulence factors in a virulent Melissococcus plutonius strain

Scientific Reports, 2021
European foulbrood (EFB) caused by Melissococcus plutonius is a major bacterial disease of honey bees. Strains of the causative agent exhibit genetic heterogeneity, and the degree of virulence varies among strains.

Osmia cornuta Is a More Suitable Managed Pollinator for Cherry and Apple Orchards Than Osmia bicornis

Journal of Applied Entomology, Volume 149, Issue 4, Page 524-535, May 2025.
ABSTRACT Managed crop pollination strongly relies on the honeybee Apis mellifera and the bumblebee Bombus terrestris, which is risky, may impact wild pollinator communities and does not always give the best pollination outcomes. The mason bees Osmia cornuta and Osmia bicornis are increasingly used as alternative crop pollinators, but it is not clear ...

A Mathematical Model of Intra-Colony Spread of American Foulbrood in European Honeybees (Apis mellifera L.).

PLoS ONE, 2015
American foulbrood (AFB) is one of the severe infectious diseases of European honeybees (Apis mellifera L.) and other Apis species. This disease is caused by a gram-positive, spore-forming bacterium Paenibacillus larvae.

Insect immunity in the Anthropocene

Biological Reviews, Volume 100, Issue 2, Page 698-723, April 2025.
ABSTRACT Anthropogenic activities result in global change, including climate change, landscape degradation and pollution, that can alter insect physiology and immune defences. These changes may have contributed to global insect decline and the dynamics of insect‐transmitted diseases.

The smell of infection: Disease surveillance in insects using volatile organic compounds

Agricultural and Forest Entomology, Volume 27, Issue 1, Page 81-89, February 2025.
Abstract Insects play crucial roles in nearly every ecosystem and provide a wide array of ecosystem services. However, both managed and wild insect populations face threats from parasites and pathogens, which require surveillance to mitigate. Current infectious disease surveillance methods for insects often involve invasive, time‐consuming and ...

What proteomics has taught us about honey bee (Apis mellifera) health and disease

PROTEOMICS, Volume 25, Issue 1-2, January 2025.
Abstract The Western honey bee, Apis mellifera, is currently navigating a gauntlet of environmental pressures, including the persistent threat of parasites, pathogens, and climate change – all of which compromise the vitality of honey bee colonies.

Pathogen and Hemocyte Dynamics in Three Apiaries Across a Bee Season

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Honey bees are dying due to a disease complex consisting of viruses, parasites, chemicals, nutritional deficiencies, and management problems. In the present study, pathogens and hemocytes were analyzed in honey bee hemolymph samples using third‐generation sequencing and flow cytometry in three apiaries over a honey bee season. Using nanopore sequencing,
