Approximately five years have elapsed since the Conference on
"Tick-borne Diseases and their Vectors" (Wilde, 1978, University of
Edinburgh) was held at the Centre for Tropical Veterinary Medicine in
Edinburgh. Theileriosis was one of the main topics at that Conference
and some 20 scientific presentations were given. Also in the same year a
Workshop on "Theileriosis" was held at the Kenyatta Conference Centre in
Nairobi (Henson & Campbell, 1977, IDRC, Ottawa). Both of these meetings
provided a valuable up- dating of theilerial diseases, and the
Proceedings have been a constant source of reference for scientists in
the ensuing years. The meetings played a significant role in setting the
scene for a number of important advances which have been made since
then. In February of this year, attention was focused on these advances
when nearly 200 scientists from over 30 countries were assembled at the
International Laboratory for Research on Animal Diseases in Nairobi for
the international conference on "Advances in the Control of
Theileriosis". The interest and concern shown in this subject has now
grown to the extent that more than 70 scientific presentations were
given over the course of a very busy week. An important facet of the
Conference was the attention given to the control of Theileriosis, since
this must be the ultimate aim of all those involved with the disease.
Control will be difficult.
