The Role of Nosema ceranae (Microsporidia: Nosematidae) in Honey Bee Colony Losses and Current Insights on Treatment [PDF]
Veterinary Sciences, 2022 Honeybee populations have locally and temporally declined in the last few years because of both biotic and abiotic factors. Among the latter, one of the most important reasons is infection by the microsporidia Nosema ceranae, which is the etiological ...

Regulation of Nosema ceranae gene expression by Bidens pilosa phytogenic treatment in infected honey bees [PDF]
Frontiers in Insect ScienceIntroductionNosema ceranae is an obligate microsporidian parasite that causes nosemosis in honey bees (Apis mellifera).MethodsIn controlled laboratory cage experiments, newly emerged worker bees were experimentally infected with N.

Development of Enzyme-Linked Immunosorbent and Immunochromatography Assays for Diagnosing Nosema ceranae Infection in Honey Bees [PDF]
InsectsNosema ceranae (N. ceranae) infection is prevalent globally, causing a decline in bee populations and significant economic losses to apiarists. Although several methods have been proposed for diagnosing Nosema infections, limitations in these methods ...

Exploring Eco-Friendly Microbial Strategies for Nosemosis Control in Honeybee. [PDF]
MicroorganismsNosemosis is an intestinal infection caused by intracellular fungal organisms from the Vairimorpha (formerly Nosema) group, which seriously harms honeybee colonies and is a factor in their worldwide decline. With the ban on fumagillin use in European apiculture and the limitations of conventional treatments, it is essential to identify sustainable ...

Prevalence of Nosemosis and Varroosis in Honey Bees in Sinop Province
Kastamonu Üniversitesi Orman Fakültesi Dergisi, 2023 Aim of study: Sinop province has a potential to progress in beekeeping. In this study, it was aimed to investigate the presence and distribution of nosemosis and varroosis in honey bees in Sinop province. Area of study: 12 villages from 7 districts (Ayancık, Boyabat, Dikmen, Durağan, Erfelek, Gerze and Saraydüzü) in Sinop province were determined

Honeybee visitation to shared flowers increases Vairimorpha ceranae prevalence in bumblebees
Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023 We conducted an observational study among different pollinator communities in agricultural fields to understand (1) how floral visitation patterns differ among pollinator species and (2) whether the visitation patterns are linked with V. ceranae prevalence in honeybees and bumblebees.

Global Change Biology, Volume 29, Issue 15, Page 4193-4211, August 2023., 2023 Metagenomics is a powerful tool to track both the population genetics and environmental stressors wildlife encounter across landscapes. This study examines wild bees across an urban gradient to determine gene flow and changes in microbiome. Densely urban areas have lower habitat connectivity and higher pathogen loads indicating regions of immediate ...
