In this work samples of bees, honey, brood, and other material were collected from an experimental apiary located in the area of Caprarola (Viterbo, Italy). These samples were used for enrichment cultures that led to the isolation of 45 strains as representatives of the existing microflora. Following physiological (growth rate, acidic pH tolerance) and taxonomic (BIOLOG system) analyses, 6 strains showing probiotic traits were selected and tested in vitro to evaluate their antagonistic activities against Paenibacillus larvae and Paenibacillus alvei.

The results obtained in this work can be considered as valuable preliminary data, useful to introduce probiotics into the world of beekeeping. It is expected, as far as regards veterinary and microbiological issues, an increasing interest of pharmaceutical industries and beekeepers into the potential development of probiotic in vivo applications.

The exploitation of beneficial microorganisms to assure the overall quality of beekeeping is then desirable and applied microbiological initiatives are expected to be pursued to accomplish the task.
