AIMS We developed a new method for detection of the intracellular parasite, Nosema ceranae, one of the most economically devastating pathogens of the honeybee. METHODS AND RESULTS 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 methods current...
Pathogens and parasites represent significant threats to the health and well-being of honeybee species that are key pollinators of agricultural crops and flowers worldwide. We conducted a nationwide survey to determine the occurrence and prevalence of pathogens and parasites in Asian honeybees, Apis cerana, in China. Our study provides evidence of infections of A. cerana by pathogenic Deformed ...
Microscopic and molecular detection of Nosema apis and Nosema ceranae in the southwest Aegean region
The honeybee pathogens Nosema ceranae and deformed wing virus (DWV) cause the collapse of honeybee colonies. Therefore, it is plausible that these two pathogens act synergistically to increase colony losses, since N.ceranae causes damage to the mid-gut epithelial ventricular cells and actively suppresses the honeybees' immune response, either of which could increase the virulence of viral patho...
The causes underlying the increased mortality of honeybee colonies remain unclear and may involve multiple stressors acting together, including both pathogens and pesticides. Previous studies suggested that infection by the gut parasite Nosema ceranae combined with chronic exposure to sublethal doses of the insecticide fipronil generated an increase in oxidative stress in the midgut of honeybee...
