Several studies have outlined that changes in the honeybee gut microbial composition may impair important metabolic functions supporting honeybees' life. Gut dysbiosis be caused by diseases like Nosema ceranae or other anthropic, environmental experimental stressors. The present work contributes to increasing knowledge on dynamics of microbiome acquisition caged honeybees, an condition frequently adopted researchers, with without infection N. ceranae, and fed a bacterial mixture control development. Changes microbiota were elucidated comparing profile open-field reared honeybees. absolute abundance major taxa was studied both NGS qPCR approaches, whereas functionality based RAST annotations manually curated. In general, all honeybees showed microbiota, [Formula: see text]-proteobacteria (Frischella, Gilliamella Snodgrassella) lacking groups. Caged infected also strong colonization Citrobacter, Cosenzaea Morganella, as well possibly pathogenic bacteria such Serratia. Serratia did not occur presence mixture. prediction revealed supplemented increased potential compared field controls.
