As the pace of veterinary
research and discovery accelerated in the 1970s and 1980s, knowledge and understanding
about many facets of M. paratuberculosis and Johne's disease became more
complete. It is impossible to single out any one individual or scientific achievement
that was of primary importance. Instead, progress was made by a global research
effort that advanced the field of paratuberculosis research.

Some of the
many individuals making
substantial contributions to this effort were:
- F. Saxegaard
Norway
- J.B. Jørgensen
Denmark
- A. Lepper Australia
- M. Thorel France
- N.J.L. Gilmour Scotland
- R. Juste Spain
- D. Collins and G. de
Lisle New Zealand
- J. Goudswaard and
G. Benedictus The Netherlands
- B. Kormendy
Hungary
- Y. Yokomizo
Japan
- C. Buergelt, R. Chiodini,
M.T. Collins, A.B. Larsen, R.Merkal,
and D. Whipple USA

 
Birth of
the International Association for Paratuberculosis and other Intestinal Mycobacterioses
Dr.
Richard Merkal (1928-1992), working at the National Animal Disease Center,
Ames, Iowa, USA, saw a need to foster closer collaboration and international
communication for individuals addressing the increasingly numerous aspects
of Johne's disease. He organized the First International Colloquium on
Paratuberculosis held in Ames in the summer of 1983. A second International
Colloquium was organized by Richard Merkal and Marie Thorel and held at
the Veterinary School in Maisons-Alfort, France in 1988. At that meeting,
Rod Chiodini and Richard Merkal decided to form the International Association
for Paratuberculosis and other Intestinal Mycobacterioses. The first Paratuberculosis
Newsletter was published on January 1, 1989. Four more international colloquiums
followed. The third, organized by Claus Buergeldt and Rod Chiodini was
held in Orlando, Florida in 1991, and the fourth, organized by John Hermon-Taylor
and Mike Collins, was held in Cambridge, England in 1994. The Fifth International
Colloquium on Paratuberculosis, organized by Mike Collins and Rod Chiodini,
was held in Madison, Wisconsin, September 29- October 4,1996. The Sixth
International Colloquium on Paratuberculosis, organized by Robin Condron,
was held February14-18, 1999 in Melbourne, Australia. The Seventh International
Colloquium on Paratuberculosis is being organized by Ramon Juste and will
be held June 12-14, 2002 in Bilbao, Spain. The proceedings of these international
colloquia provide a concise summary of the latest developments in the
field of paratuberculosis and can be obtained from the Association via
its website: http://www.paratuberculosis.org
