Screening of anti-nosemosis active compounds based on the structure-activity correlation

Journal of Asia-Pacific Entomology, 2021
Abstract Nosema ceranae infection in Apis mellifera acts as a virulent pathogenic factor of honeybee colony collapse. Fumagillin is the only effective antimicrobial agent currently used against the microsporidial parasite N. ceranae. However, the toxicity of fumagillin is a concern.

A Simple Model of Between-Hive Transmission of Nosemosis

Springer Proceedings in Mathematics and Statistics, 2018
We present a simple metapopulation extension of a mathematical model of Nosemosis for the between-hive transmission of the disease in an apiary. The transmission of the disease between neighbouring colonies is modeled by impulsive transfer of pathogens. The model is studied in computer simulations.

Antimicrosporidian activity of sulphated polysaccharides from algae and their potential to control honeybee nosemosis

Carbohydrate Polymers, 2015
Nosemosis is one of the most common and widespread diseases of adult honeybees. The causative agents, Nosema apis and Nosema ceranae, belong to microsporidia some obligate intracellular eukaryotic parasites. In this study, 10 sulphated polysaccharides from algae were evaluated for their antimicrosporidian activity.

The Prevalence of Nosemosis in Honey Bee in The Province of Kars

, 2004
 Kars yöresindeki bal arılarında (Apis mellifera) nosemosis’ in prevalansını saptamak amacıyla 8 ana yerleşim yerinden tesadüfen seçilen 50 arılıktan arı numuneleri alınmıştır. Arılıklar Mayıs 2001- Eylül 2002 tarihleri arasında bir kez ziyaret edilmiş ve toplam 1892 koloniden rastgele seçilen 343 (% 18.13) arı kovanından arı örnekleri alınmıştır.
