Does Nosema ceranae Wipe Out Nosema apis in Turkey? [PDF]

Iranian Journal of Parasitology, 2016
Background: The aim of this study was to determine the prevalence of the Nosema ceranae and Nosema apis among apiaries using both spore counts and multiplex PCR and the replacement of N. apis by N. ceranae in some regions of Turkey.

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 Sci
Conventional 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

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]

Microorganisms
Honeybee (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]

Insects
The 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

Individual Variability of Nosema ceranae Infections in Apis mellifera Colonies

Insects, 2012
Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N.
