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.

Seasonal variability of prevalence and occurrence of multiple infections shape the population structure of Crithidia bombi, an intestinal parasite of bumblebees (Bombus spp.) [PDF]

open access: yesMicrobiologyOpen, 2012
AbstractErgonomic growth phases of annual social insect societies strongly influence horizontally transmitted parasites. Herein, we focused on the impact of temporal changes in host demography on the population structure of a horizontally transmitted parasite.

Trypanosoma spp. Neobats: Insights about those poorly known trypanosomatids

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2021
Bats are infected with several trypanosomatid species; however, assessing the diversity of this interaction remains challenging since there are species apparently unable to grow in conventional culture media.

Parasites of the genus Nosema, Crithidia and Lotmaria in the honeybee and bumblebee populations: a case study in India

open access: yesВавиловский журнал генетики и селекции, 2018
The populations of honeybees and bumblebees have been decreasing around the world in the recent decades. A variety of pathogens and parasites, including  bacteria, fungi, protozoa, nematodes, mites and insects play signi ficant role in honeybee and ...

The Pathogens Spillover and Incidence Correlation in Bumblebees and Honeybees in Slovenia

open access: yesPathogens, 2021
Slovenia has a long tradition of beekeeping and a high density of honeybee colonies, but less is known about bumblebees and their pathogens. Therefore, a study was conducted to define the incidence and prevalence of pathogens in bumblebees and to ...

Methods matter: the influence of method on infection estimates of the bumblebee parasite Crithidia bombi

open access: yesParasitology, 2023
The bumblebee gut parasite, Crithidia bombi, is widespread and prevalent in the field. Its interaction with Bombus spp. is a well-established epidemiological model.

Do pesticide and pathogen interactions drive wild bee declines?

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2022
There is clear evidence for wild insect declines globally. Habitat loss, climate change, pests, pathogens and environmental pollution have all been shown to cause detrimental effects on insects. However, interactive effects between these stressors may be

Core symbionts, age at inoculation and diet affect colonization of the bumblebee gut by a common bacterial pathogen. [PDF]

open access: yesJ Anim Ecol
This paper examines ecological interactions within the bumblebee gut microbiome and between the microbiome and host using field sampling and controlled experiments. We demonstrate that non‐core bacteria occur frequently in high abundance in wild bumblebee gut microbiomes.

Prevalence of infection by the microsporidian Nosema spp. in native bumblebees (Bombus spp.) in northern Thailand.

open access: yesPLoS ONE, 2019
Bumblebees (tribe Bombini, genus Bombus Latreille) play a pivotal role as pollinators in mountain regions for both native plants and for agricultural systems.
