Project description:Newly emerged adult workers (24 hours old) were infected with 25,000 Nosema apis spores and 25,000 Nosema ceranae spores in sucrose solution. Controls were fed sucrose. Workers were maintained in cages in an incubator and collected at 14 days post-infection. Fat bodies (eviscerated abdomens) were dissected and whole genome expression in this tissue was compared across treatments using microarrays.
Project description:The microsporidia Nosema ceranae are intracellular parasites that proliferate in the midgut epithelial cells of honey bees (Apis mellifera). To analyze the pathological effects of those microsporidia, we orally infected honey bee workers 7 days after their emergence. Bees were flash frozen 15 days after the infection. Then, the effects on the gut ventriculi were analyzed and compared to non-infected (control) bees. Comparisons of control vs Nosema ceranae bees
Project description:In this study we addressed whether the transcriptome profile in the honey bee brain is similar for two major parasites of honey bee, Varroa destructor and Nosema ceranae. Honey bees parasitized by these two parasites show accelerated behavioral maturation and deficiences in orientation and learning/memory that we hoped to characterized at the transcriptomic level. honey bee adults infested by Varroa destructor or Nosema ceranae compared to control bees, in duplicate
