Gas chromatography-mass spectrometry metabolite profiling of worker honey bee (Apis mellifera L.) hemolymph for the study of Nosema ceranae infection

► GC/MS profiling of hemolymph for the study of infection of honey bee by Nosema ceranae. ► Development of a metabolomics model for N. ceranae diagnosis. ► N. ceranae imposes nutritional and energetic stress to the host. ► Infection results in decreased levels of various carbohydrates and amino acids.
