Infra-population and -community dynamics of the parasites Nosema apis and Nosema ceranae, and consequences for honey bee (Apis mellifera) hosts. [PDF]
PLoS ONE, 2014 Nosema spp. fungal gut parasites are among myriad possible explanations for contemporary increased mortality of western honey bees (Apis mellifera, hereafter honey bee) in many regions of the world.

The Effects of Nosema apis and Nosema ceranae Infection on Survival and Phenoloxidase Gene Expression in Galleria mellonella (Lepidoptera: Galleriidae) Compared to Apis mellifera [PDF]
Insects, 2021 The study aims to prove the possibility of colonization of N. apis and N. ceranae to the intestine of the greater wax moth, detect the differences of greater wax moth based on the presence of Nosema species and examine the effect of Nosema species on the

Extracts From Grapefruit (Citrus paradisi) Peel via Microwave-Assisted and Conventional Extractions: Evaluation of Nosema Infection and Toxicity in Honey Bees. [PDF]
Vet Med SciConventional and microwave‐assisted extractions of grapefruit peels were optimized using response surface methodology (RSM) based on TPC, TFC, and antioxidant activity (DPPH). The phytochemical profiles of the two optimum extracts were characterized via HPLC before evaluating their acute and chronic toxicity, as well as their effects on honey bee (Apis

Nosema Ceranae Interactions with Nosema apis and Black Queen Cell Virus [PDF]
Agriculture, 2021 Nosema ceranae is a relatively new pathogen of the honeybee (Apis mellifera) and the course of type C nosemosis (the disease that it causes) is not entirely known.

Winter Bottom Beehive Cadavers as a Tool for Assessing Nosema ceranae Infestation Intensity in Honeybee Colonies in Regions with Different Beekeeping Densities in Slovakia [PDF]
MicroorganismsHoneybee (Apis mellifera) colony density is frequently assumed to influence the level of Nosema ceranae infestation in managed colonies. In Slovakia, winter bottom beehive debris (dead worker bees) is routinely collected between January and February ...

First Molecular Detection and Characterization of Nosema ceranae in Honey Bees (Apis mellifera) from the Northern Highlands of Ecuador [PDF]
InsectsThe development of beekeeping in Ecuador has generated the need to strengthen the bee health program. Research on the main pathogens responsible for diseases like nosemosis, which can severely impact bee health, is of special interest. This study aims to

Dynamics of Nosema apis and Nosema ceranae Co-Infection Seasonally in Honey Bee (Apis mellifera L.) Colonies [PDF]
Journal of Apicultural Science, 2019 Nosema apis is a pathogen spesific for the European honeybee, Apis mellifera L., while Nosema ceranae is specific for the Asian honeybee, Apis cerana. Turkey provides different environmental and host conditions for both Nosema species.

The microsporidian parasites Nosema ceranae and Nosema apis are widespread in honeybee (Apis mellifera) colonies across Scotland [PDF]
Parasitology Research, 2012 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. It is thought that there may be a temperature barrier to its infiltration into countries in colder climates.

Population Genetics of Nosema apis and Nosema ceranae: One Host (Apis mellifera) and Two Different Histories. [PDF]
PLoS One, 2015 Two microsporidians are known to infect honey bees: Nosema apis and Nosema ceranae. Whereas population genetics data for the latter have been released in the last few years, such information is still missing for N. apis. Here we analyze the patterns of nucleotide polymorphism at three single-copy loci (PTP2, PTP3 and RPB1) in a collection of Apis ...

Immune priming of honey bees protects against a major microsporidian pathogen. [PDF]
Pest Manag SciWe immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...
