The CEC common research programme on enzootic bovine
leukosis (EBL) was terminated last year. During the eight-
year period a number of workshops and symposia were sponsored
by the CEC. This volume contains the proceedings of the last
the "Fifth International Symposium on Enzootic Bovine
Leukosis" held at Tübingen (1982), where the first workshop
(1974) marked the beginning of the research programme.
Included are also the papers of the last workshop held at the
Moredun Institute, Edinburgh, 13-15 September 1983, a
leftover from the fourth symposium (Bologna, 1980) and the
"Evaluation of the CEC Common Research Programme on Enzootic
Bovine Leukosis (EBL)" by Professor Y.BECKER, Scientific adviser,
Hebrew University of Jerusalem conceived after the workshop held in
Dublin (1981).
At this point I wish to express the appreciation of the
participants to Professor Becker for his engagement and
advice offered during those years.
Eight years of EBL research have greatly widened our
knowledge on this slow disease in the fields of basic and
applied science. Without the support of the CEC this progress
would not have been achieved during such a relatively short
period of time. Not only EC countries will benefit from this
research programme but all those which have a cattle
population infected with bovine leukosis virus.
Although funds became rather limited during the later
years it was still possible to invite scientists from non-EC
countries to participate at the symposia and have their
papers included in the proceedings. Some blemishes will be noticeable during the study of
the proceedings. Those are partly due to different spelling
by the authors. I am specially indebted to Mrs. Helen C.
Jackson for help in improving the English of papers written
by scientists whose mother tongue is not English (American),
to Mrs. Marie-Luise Donner, Mrs. Christel Roming and Mrs.
Claudia Dicker for their efforts in typing the manuscripts
and to Mr. Peter Schröter for the improvement of a number of
figures. I am especially grateful for the skilful technical
assistance provided through many years by Mrs. Gabriele
Kuebart and Mrs. Barbara Zoeth.
Last but no least I would like to thank Mr. J. Connell,
CEC Brussels, for his tremendous interest in the subject and
his personal engagement in this matter.
Although the EBL programme has been concluded I am sure
that contacts beyond borders will continue whereeyer EBL
research is still conducted. A number of problems have been
solved, many questions, however, remain still open.
