Disentangling the heterogeneity of Crithidia bombi infections in bumblebee populations [PDF]

open access: yes, 2015
Weltweiter Biodiversitätsverlust und (neu) auftretende Infektionskrankheiten stellen eine ernsthafte Gefahr für Mensch und Umwelt dar und stehen im Fokus derzeitiger Forschungsaktivitäten. Hummeln spielen eine Schlüsselrolle bei der effektiven Bestäubung

Recognition and avoidance of contaminated flowers by foraging bumblebees (Bombus terrestris). [PDF]

open access: yesPLoS ONE, 2011
Bumblebee colonies are founded by a single-mated queen. Due to this life history trait, bumblebees are more susceptible to parasites and diseases than polyandrous and/or polygynous social insects.

Short communication: First data on the prevalence and distribution of pathogens in bumblebees (Bombus terrestris and Bombus pascuorum) from Spain

open access: yesSpanish Journal of Agricultural Research, 2017
Bumblebees provide pollination services not only to wildflowers but also to economically important crops. In the context of the global decline of pollinators, there is an increasing interest in determining the pathogen diversity of bumblebee species.

Unbiased RNA Shotgun Metagenomics in Social and Solitary Wild Bees Detects Associations with Eukaryote Parasites and New Viruses. [PDF]

open access: yesPLoS ONE, 2016
The diversity of eukaryote organisms and viruses associated with wild bees remains poorly characterized in contrast to the well-documented pathosphere of the western honey bee, Apis mellifera.

Immune gene expression in Bombus terrestris: signatures of infection despite strong variation among populations, colonies, and sister workers. [PDF]

open access: yesPLoS ONE, 2013
Ecological immunology relies on variation in resistance to parasites. Colonies of the bumblebee Bombus terrestris vary in their susceptibility to the trypanosome gut parasite Crithidia bombi, which reduces colony fitness.

The Epidemiological Situation of the Managed Honey Bee (Apis mellifera) Colonies in the Italian Region Emilia-Romagna

open access: yesVeterinary Sciences, 2022
The recent decades witnessed the collapse of honey bee colonies at a global level. The major drivers of this collapse include both individual and synergic pathogen actions, threatening the colonies’ survival.

Amplicon Sequencing of Variable 16S rRNA from Bacteria and ITS2 Regions from Fungi and Plants, Reveals Honeybee Susceptibility to Diseases Results from Their Forage Availability under Anthropogenic Landscapes

open access: yesPathogens, 2021
European Apis mellifera and Asian Apis cerana honeybees are essential crop pollinators. Microbiome studies can provide complex information on health and fitness of these insects in relation to environmental changes, and plant availability.

Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? [PDF]

open access: yesPLoS ONE, 2008
The conservation of insect pollinators is drawing attention because of reported declines in bee species and the 'ecosystem services' they provide. This issue has been brought to a head by recent devastating losses of honey bees throughout North America ...

Genetic variation and microbiota in bumble bees cross-infected by different strains of C. bombi

open access: yesPLoS ONE, 2022
The bumblebee Bombus terrestris is commonly infected by a trypanosomatid gut parasite Crithidia bombi. This system shows a striking degree of genetic specificity where host genotypes are susceptible to different genotypes of parasite.
