So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]

open access: yes, 2014
Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.

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

open access: yesScientific 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.

Biological effects of paenilamicin, a secondary metabolite antibiotic produced by the honey bee pathogenic bacterium Paenibacillus larvae [PDF]

open access: yes, 2014
Paenibacillus larvae is the etiological agent of American Foulbrood (AFB) a world-wide distributed devastating disease of the honey bee brood. Previous comparative genome analysis and more recently, the elucidation of the bacterial genome, provided ...

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

open access: yesJournal 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.).

open access: yesPLoS 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.

Diversity of honey stores and their impact on pathogenic bacteria of the honeybee, Apis mellifera [PDF]

open access: yes, 2014
Honeybee colonies offer an excellent environment for microbial pathogen development. The highest virulent, colony killing, bacterial agents are Paenibacillus larvae causing American foulbrood (AFB), and European foulbrood (EFB) associated bacteria ...

Insect immunity in the Anthropocene

open access: yesBiological 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 detection of Melissococcus pluton in honey bees (Apis mellifera) and their products using a hemi-nested PCR [PDF]

open access: yes, 2003
A hemi-nested polymerase chain reaction (PCR) was further developed for the detection of Melissococcus pluton in adult bees and honey bee products. A chloroform:isoamyl alcohol DNA extraction method was used to provide template from 154 samples of adult ...

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

open access: yesAgricultural 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 ...

Controlling European foulbrood with the shook swarm method and oxytetracycline in the UK [PDF]

open access: yesApidologie, 2003
Colonies infected with European foulbrood (EFB) were treated with the shook swarm method in combination with oxytetracycline (OTC) and compared with those treated with OTC alone, the usual treatment for EFB in England and Wales. Success rates and instances of recurrence in the following season were recorded in the seasons 2000 and 2001 respectively ...
