The Impact of Vairimorpha (Nosema) ceranae Natural Infection on Honey Bee (Apis mellifera) and Bee Bread Microbiota

چکیده

Honey bees face new challenges, ranging from climate crisis to emerging pathogens such as Vairimorpha (Nosema) ceranae that synergistically cause a syndrome designated colony collapse disorder (CCD). This study employed metataxonomic approach in order investigate if V. affects gut microbiota (bacteria and fungi) of adult A. mellifera honey well bee bread (BB) stored colonies demonstrating severe infection (spore counts >2,500,000 per bee) compared with exhibiting very low spore (<40,000 bee). Alpha-diversity analysis revealed an overall decrease microbial diversity reflected by number observed unique operating taxonomic units (OTUs) regarding both bacteria fungi ΒΒ samples. Further demonstrated Podosphaera spp. were absent BB samples collected high counts, while relative abundance Blumeria was significantly decreased. Interestingly, Rosenbergiella increased counts. The reason for these findings remains elusive. Although further research is warranted, reduced certain groups may serve biomarkers collapse.

Effects of Nosema apis, N. ceranae, and coinfections on honey bee (Apis mellifera) learning and memory

Western honey bees (Apis mellifera) face an increasing number of challenges that in recent years have led to significant economic effects on apiculture, with attendant consequences for agriculture. Nosemosis is a fungal infection of honey bees caused by either Nosema apis or N. ceranae. The putative greater virulence of N. ceranae has spurred interest in understanding how it differs from N. api...

Immune suppression in the honey bee (Apis mellifera) following infection by Nosema ceranae (Microsporidia).

Two microsporidia species have been shown to infect Apis mellifera, Nosema apis and Nosema ceranae. This work presents evidence that N. ceranae infection significantly suppresses the honey bee immune response, although this effect was not observed following infection with N. apis. Immune suppression would also increase susceptibility to other bee pathogens and senescence. Despite the importance...

Chronic Bee Paralysis Virus and Nosema ceranae Experimental Co-Infection of Winter Honey Bee Workers (Apis mellifera L.)

Chronic bee paralysis virus (CBPV) is an important viral disease of adult bees which induces significant losses in honey bee colonies. Despite comprehensive research, only limited data is available from experimental infection for this virus. In the present study winter worker bees were experimentally infected in three different experiments. Bees were first inoculated per os (p/o) or per cuticle...

Honey Bee Apis mellifera Parasites in the Absence of Nosema ceranae Fungi and Varroa destructor Mites

Few areas of the world have western honey bee (Apis mellifera) colonies that are free of invasive parasites Nosema ceranae (fungi) and Varroa destructor (mites). Particularly detrimental is V. destructor; in addition to feeding on host haemolymph, these mites are important vectors of several viruses that are further implicated as contributors to honey bee mortality around the world. Thus, the b...

Gut Pathology and Responses to the Microsporidium Nosema ceranae in the Honey Bee Apis mellifera

The microsporidium Nosema ceranae is a newly prevalent parasite of the European honey bee (Apis mellifera). Although this parasite is presently spreading across the world into its novel host, the mechanisms by it which affects the bees and how bees respond are not well understood. We therefore performed an extensive characterization of the parasite effects at the molecular level by using geneti...
