Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

open access: yes, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Genome-Wide Characterization and Comparative Genomic Analysis of the Serpin Gene Family in Microsporidian Nosema bombycis

open access: yesInternational Journal of Molecular Sciences, 2022
Microsporidia are ubiquitous in the environment, infecting almost all invertebrates, vertebrates, and some protists. The microsporidian Nosema bombycis causes silkworms pébrine disease and leads to huge economic losses.

Prevalence of the Microsporidian Nosema spp. in Honey Bee Populations (Apis mellifera) in Some Ecological Regions of North Asia

open access: yesVeterinary Sciences, 2020
Two species of microsporidia, Nosema apis and Nosema ceranae, are obligate intracellular parasites that are widespread in the world and cause the infectious disease (Nosemosis) of the Western honey bee Apis mellifera.

The impact of a vertically transmitted microsporidian, Nosema granulosis on the fitness of its Gammarus duebeni host under stressful environmental conditions [PDF]

open access: yes, 2003
Although purely vertically transmitted parasites are predicted to cause low pathogenicity in their hosts, the effects of such parasites on host fitness under stressful environmental conditions have not previously been assessed.

Nosema Disease of European Honey Bees

open access: yesJournal of Fungi, 2021
Nosematosis is currently a frequently discussed honey bee disease caused by two types of Microsporidia: Nosema apis and Nosema ceranae. Nosematosis as an intestinal disease caused by these species is one of the main factors associated with the weakening ...

Horizontal transfer of parasitic sex ratio distorters between crustacean hosts [PDF]

open access: yes, 1998
Parasitic sex ratio distorters were artificially transferred within and between crustacean host species in order to study the effects of parasitism on host fitness and sex determination and to investigate parasite–host specificity. Implantation of Nosema

Determination of spore longevity and viability of Nosema apis and Nosema ceranae according to storage conditions

open access: yesThe EuroBiotech Journal, 2017
Honey bee colonies are often infected with Nosema apis and Nosema ceranae which cause adult honey bee disease called nosemosis. All honey bee colony members can be infected with these species.

Physiological effects of the interaction between Nosema ceranae and sequential and overlapping exposure to glyphosate and difenoconazole in the honey bee Apis mellifera.

open access: yesEcotoxicology and Environmental Safety, 2021
Pathogens and pollutants, such as pesticides, are potential stressors to all living organisms, including honey bees. Herbicides and fungicides are among the most prevalent pesticides in beehive matrices, and their interaction with Nosema ceranae is not ...

Microsporidia and invertebrate hosts: genome-informed taxonomy surrounding a new lineage of crayfish-infecting <i>Nosema</i> spp. (Nosematida). [PDF]

open access: yesFungal Divers
The Microsporidia, an often overlooked fungal lineage, exhibit increasing diversity and taxonomic understanding with the use of genomic techniques. They are obligate parasites infecting a diversity of hosts, including crustaceans.
