Isolation and characterization of A14.2, a strain with immunomodulating activity on .

Considering the economic and environmental role played by bees and their present threats it is necessary to develop food supplements favoring their health. The aim of this work was to isolate and characterize an immunomodulating probiotic capable to improve the health of honeybee colonies. For this purpose, bacterial strains were isolated from bees (N = 180) obtained at three apiaries.
