The measurement and interrelationships of infections with Nosema apis and Malpighamoeba mellificae of honey-bee populations

, 1968
The numbers of spores of Nosema apis or cysts of Malpighamoeba mellificae, in samples of honey bees, (Apis mellifera) were correlated with the percentage of bees infected.

Apis cerana gut microbiota contribute to host health though stimulating host immune system and strengthening host resistance to Nosema ceranae [PDF]

Royal Society Open Science, 2020
Gut microbial communities play vital roles in the modulation of many insects' immunity, including Apis mellifera. However, little is known about the interaction of Apis cerana gut bacteria and A. cerana immune system.

Detection of Nosema spp. in Worker Bees of Different Ages During the Flow Season

Journal of Apicultural Science, 2012
Celem badań było ustalenie, który gatunek Nosema występuje u robotnic Apis mellifera pobieranych z różnych miejsc ula w sezonie pasiecznym. W lutym 2010 roku zbadano osypy zimowe pszczół z 30 rodzin pszczelich.

Environment and Pollen Diversity Differentially Affect the Gut Microbiomes of Introduced Honeybees and Bumblebees

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Invasive species may exhibit shifts in their gut microbiome in response to novel environments and diet, but this may differ across host species and their time since colonisation. We investigate if site environmental variables and foraged pollen resources differentially shape the gut microbiomes of two bee species with contrasting introduction ...

North American Propolis Extracts From Upstate New York Decrease Nosema ceranae (Microsporidia) Spore Levels in Honey Bees (Apis mellifera)

Frontiers in Microbiology, 2020
Nosema ceranae infections in honey bees (Apis mellifera) pose a severe threat to colony health. Beekeepers have used dicyclohexylammonium fumagillin to control Nosema apis, although it may be ineffective against N. ceranae. We investigated the ability of

Comparison of the energetic stress associated with experimental Nosema ceranae and Nosema apis infection of honeybees (Apis mellifera)

Parasitology Research, 2011
Nosema ceranae is a relatively new and widespread parasite of the western honeybee Apis mellifera that provokes a new form of nosemosis. In comparison to Nosema apis, which has been infecting the honeybee for much longer, N. ceranae seems to have co-evolved less with this host, causing a more virulent disease. Given that N. apis and N.

Drivers of Viral Prevalence in Landscape‐Scale Pollinator Networks Across Europe: Honey Bee Viral Density, Niche Overlap With This Reservoir Host and Network Architecture

Ecology Letters, Volume 29, Issue 1, January 2026.
Viral spill‐over from honey bees is a potential threat to wild pollinators. We used causal modelling approaches to detect the main drivers of spill‐over. Honey bee viral density, niche overlap with honey bees, urbanisation and plant‐pollinator network structure all played an important role in the transmission of BQCV, DWV‐A and DWV‐B.

Translocation of imidacloprid from coated rape (Brassica napa) seeds to nectar and pollen [PDF]

, 2013
Bees and other pollinating insects contribute significantly to the world’s production of edible crops. Bees and bumblebees are threatened by modern agricultural practices like monocropping, destruction of natural habitats and pesticide use.

Zymography of proteases in honey bees (Apis Mellifera) infected with Nosema ceranae [PDF]

Veterinarski Glasnik
Nosemosis is one of the most important honey bee diseases and is caused by two fungal species of the genus Nosema, i.e., Nosema apis and Nosema ceranae.
