Abstract

The invention relates to a probiotic mixture for the protection of bees'"'"' health, and more specifically for the protection from microbial pathologies, such as those caused by Paenibacillus larvae, etiological agent of the American Foulbrood Disease (AFD).

Claims

1. Composition for the prevention and control of bacterial diseases in bees, comprising symbiotic bacteria of Apis mellifera or of other pollinating insects isolated therefrom.

2. Composition as claimed in claim 1, wherein the symbiotic bacteria comprise one or two spore-forming bacteria combined with one another and/or combined with one or more acetic bacteria.

3. Composition as claimed in claim 2, wherein the spore-forming bacteria are selected from Bacillus thuringensis and Brevibacillus laterosporus and the acetic bacterium is Saccharibacter sp.

4. Composition as claimed in claim 1, wherein the disease is a bacterial disease of bees.

5. Composition as claimed in claim 4, wherein the bacterial disease of bees is caused by Paenibacillus larvae or Melissococcus pluton.

6. Composition as claimed in claim 1 in the form of a dry bacterial biomass in powder form for dilution in water, syrup, sugar syrup, solid bar or cake.

7. Method for the control and prevention of diseases of bees, comprising contacting bees/larvae, honeycombs or hives with an effective quantity of a composition comprising two spore-forming bacteria.

8. Method as claimed in claim 7, wherein the bee disease is a bacterial disease.

9. Method as claimed in claim 8, wherein the bacterial bee disease is caused by Paenibacillus larvae or Melissococcus pluton.

10. Method as claimed in claim 7, wherein the spore-forming bacteria are selected from Bacillus thuringensis and Brevibacillus laterosporus and the acetic bacterium is Saccharibacter sp.

11. Method as claimed in claim 7, wherein the composition is in the form of a dry bacterial biomass in powder form for dilution in water, syrup, sugar syrup, solid bar or cake.

12. Method as claimed in claim 7, wherein the two spore-forming bacteria are combined with an acetic bacterium.
