Flight performance of actively foraging honey bees is reduced by a common pathogen [PDF]

, 2016
ArticleSudden and severe declines in honey bee (Apis mellifera) colony health in the US and Europe have been attributed, in part, to emergent microbial pathogens, however, the mechanisms behind the impact are unclear.

The microsporidian parasites Nosema ceranae and Nosema apis are widespread in honeybee (Apis mellifera) colonies across Scotland [PDF]

, 2013
Nosema ceranae is spreading into areas where Nosema apis already exists. N. ceranae has been reported to cause an asymptomatic infection that may lead, ultimately, to colony collapse.

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 ...

Nosema apis and Nosema ceranae in Beehives of the Apulian Region of Italy: How Citizen Science Can Support Scientific Research

Agriculture
Nosema apis and Nosema ceranae are two well-known pathogens affecting the health of honeybees. To help understand how honeybee colonies are affected by these pathogens, the aim of this study was to analyze the impact of Nosema ceranae and Nosema apis in ...

Stable genetic diversity despite parasite and pathogen spread in honey bee colonies [PDF]

, 2015
In the last decades, the rapid spread of diseases, such as varroosis and nosemosis, associated with massive honey bee colonies mortality around the world has significantly decreased the number and size of honey bee populations and possibly their genetic ...

Sublethal effects of acaricides and Nosema ceranae infection on immune related gene expression in honeybees [PDF]

, 2016
Nosema ceranae is an obligate intracellular parasite and the etiologic agent of Nosemosis that affects honeybees. Beside the stress caused by this pathogen, honeybee colonies are exposed to pesticides under beekeeper intervention, such as acaricides to ...
