The Action organised several meetings and symposia, sometimes organised together with international conferences. There were almost no books of abstracts or proceedings (except for the larger conference) produced from these meetings. Detailed STSM reports are not available. Members of COST 845 produced a large number of publications in the area of brucellosis research covered by the Action. The original chair of this Action resigned in 2005 leaving it in a moribund state. Special mention must be made of the efforts made by the rapporteur (Professor Peter Raspor) and the COST office to have a new chair elected. This was achieved succcessfully, and the new chair (Dr. David O’Callaghan) is to be congratulated in bringing the Action back to life and to concluding it successfully under these very difficult circumstances.
