Kontroversen über Nosema ceranae (Mikrosporidien)

, 2022
Honey bees are likely to be the best-known bees, but they represent only a fraction of the world's existing bee species. The vast majority of bees is not kept by humans but considered as wildlife species. For these wild bees, according to current reports, declines in number and diversity can be observed.

First Identification of Nosema Ceranae (Microsporidia) Infecting Apis Mellifera in Venezuela [PDF]

Journal of Apicultural Science, 2017
Nosema ceranae is a pathogen of Apis mellifera, which seems to have jumped from its original host Asiatic honey bee Apis ceranae. Nosemosis which affects the honey bee Apis mellifera is caused by two parasitic fungi described as etiologic agents of the ...

Presence of Nosema ceranae associated with honeybee queen introductions

Infection, Genetics and Evolution, 2014
Microsporidiosis caused by Nosema species is one of the factors threatening the health of the honeybee (Apis mellifera), which is an essential element in agriculture mainly due to its pollination function. The dispersion of this pathogen may be influenced by many factors, including various aspects of beekeeping management such as introduction of queens

Nosema ceranae Escapes Fumagillin Control in Honey Bees

PLoS Pathogens, 2013
Fumagillin is the only antibiotic approved for control of nosema disease in honey bees and has been extensively used in United States apiculture for more than 50 years for control of Nosema apis. It is toxic to mammals and must be applied seasonally and with caution to avoid residues in honey.

Effect of Baicalin on the Proliferation of <i>Nosema ceranae</i> in <i>Apis cerana</i>. [PDF]

Insects
Nosema ceranae is a common and highly contagious fungal pathogen that primarily infects the gut of adult honeybees, causing nosemosis. As a chronic disease of the digestive system, it poses a global threat to honeybee health and colony sustainability.

Colonisation Patterns of Nosema ceranae in the Azores Archipelago. [PDF]

Vet Sci, 2022
Nosema ceranae is a highly prevalent pathogen of Apis mellifera, which is distributed worldwide. However, there may still exist isolated areas that remain free of N. ceranae. Herein, we used molecular tools to survey the Azores to detect N. ceranae and unravel its colonisation patterns.

Proteasome Inhibition Is an Effective Treatment Strategy for Microsporidia Infection in Honey Bees

Biomolecules, 2021
The microsporidia Nosema ceranae is an obligate intracellular parasite that causes honey bee mortality and contributes to colony collapse. Fumagillin is presently the only pharmacological control for N. ceranae infections in honey bees.

A serological method for detection of Nosema ceranae [PDF]

Journal of Applied Microbiology, 2012
We developed a new method for detection of the intracellular parasite, Nosema ceranae, one of the most economically devastating pathogens of the honeybee.The SWP-32 antibody was used for the development of an enzyme-linked immunosorbent assay (ELISA). We also compared the efficiency of this ELISA to microscopy and quantitative real-time (qRT) PCR, the ...
