Primeira detecção molecular de co-infecção de vírus de abelhas em Bombus atratus assintomática na América do Sul [PDF]

, 2013
Pollination is critical for food production and has the particularity of linking natural ecosystems with agricultural production systems. Recently, losses of bumblebee species have been reported worldwide.

Organic farming and annual flower strips reduce parasite prevalence in honeybees and boost colony growth in agricultural landscapes

Journal of Applied Ecology, Volume 61, Issue 9, Page 2146-2156, September 2024.
Landscape features can affect pollinators directly through the provision of food resources and indirectly through modulation of parasite prevalence. To promote honeybee colony health in agro‐ecosystems, our results suggest that organic agriculture and annual flower strips should be prioritized conservation measures. Landscape management should consider

Evaluation of the Effectiveness of Selected Treatments of Nosema Spp. Infection by the Hemocytometric Method and Duplex Pcr

Acta Veterinaria, 2016
Recent years have witnessed an increase in the mortality of honey bees in many regions of the world. The observed decrease in the bee population results from a combination of factors, and microsporidian parasites Nosema apis and N.

Individual Variability of Nosema ceranae Infections in Apis mellifera Colonies

Insects, 2012
Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N.

Honey bee-collected pollen is a potential source of Ascosphaera apis infection in managed bumble bees [PDF]

, 2019
The trade of bumble bees started in the early nineties for pollinator-dependent greenhouse plants. Nowadays, its rearing and transport have received public attention, since managed bees can transfer pathogens to wild bee populations.

Interactions between microsporidia and other members of the microbiome

Journal of Eukaryotic Microbiology, Volume 71, Issue 5, September/October 2024.
Abstract The microbiome is the collection of microbes that are associated with a host. Microsporidia are intracellular eukaryotic parasites that can infect most types of animals. In the last decade, there has been much progress to define the relationship between microsporidia and the microbiome.

Sex-specific differences in pathogen susceptibility in honey bees (Apis mellifera).

PLoS ONE, 2014
Sex-related differences in susceptibility to pathogens are a common phenomenon in animals. In the eusocial Hymenoptera the two female castes, workers and queens, are diploid and males are haploid.

Genome evolution in intracellular parasites: Microsporidia and Apicomplexa

Journal of Eukaryotic Microbiology, Volume 71, Issue 5, September/October 2024.
Abstract Microsporidia and Apicomplexa are eukaryotic, single‐celled, intracellular parasites with huge public health and economic importance. Typically, these parasites are studied separately, emphasizing their uniqueness and diversity. In this review, we explore the huge amount of genomic data that has recently become available for the two groups. We

The role of disease in bee foraging ecology [PDF]

, 2017
Diseases have important but understudied effects on bee foraging ecology. Bees transmit and contract diseases on flowers, but floral traits including plant volatiles and inflorescence architecture may affect transmission. Diseases spill over from managed
