Colonies infected with European foulbrood (EFB) were treated with the shook swarm method in combination with oxytetracycline (OTC) and compared with those treated with OTC alone, the usual treatment for EFB in England and Wales. Success rates and instances of recurrence in the following season were recorded in the seasons 2000 and 2001 respectively. Both treatments had similar success rates with respect to elimination of EFB in 2000. Shook swarm plus OTC treatment resulted in a lower level of EFB recurrence in the 2001 season than OTC treatment alone. Colonies treated with the shook swarm plus OTC method showed a recurrence rate of 4.8%, whereas those treated with OTC alone had a recurrence in 21.1% of cases. The differences were shown to be significant at the 10% level. These results suggest that the shook swarm plus OTC method could be a valid method for EFB treatment and control in the UK.
