A Review of Nosema cerane and Nosema apis: Caracterization and Impact for Beekeeping
Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2019 Two microsporidia have been described infecting honey bees worldwide: Nosema apis and Nosema ceranae. The infecting forms of the parasite are the spores, ingested by the adult host insects. Studies demonstrated that the infection with Nosema spp. range from less than 1 to 100 percent, this disease reduces worker longevity by 22-44% which in turn ...

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees
Ecology and Evolution, Volume 16, Issue 6, June 2026.Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Ecology and Evolution, Volume 16, Issue 6, June 2026.In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

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.

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 ...

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.

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.

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.
