  • Patent number: 3954969
    Abstract: A process for treating and restoring honeycombs infected with American Foulbrood Disease (Bacillus larvae). Includes the steps of applying a liquid suspension containing living spores of the mold Penicillium waksmani Zaleski (or near) to the cell wall surfaces of a honeycomb infected with American Foulbrood. The concentration of living spores of Penicillium waksmani Zaleski (or near) in the suspension is approximately 5 to 10 million spores per milliliter of suspension. After the application of the liquid suspension to the honeycomb, the honeycomb is then allowed to remain at a temperature of about 65.degree. to 75.degree.F and at a relative humidity of about 85% for a period of time to permit sufficient growth of the mold Penicillium waksmani Zaleski (or near) so that the mold covers the honeycomb, including the cell walls. The honeycomb is then placed in a well populated beehive where the bees remove American foulbrood scales and the dried mold and consequently clean each honeycomb cell.
