The ADG held its first International Symposium at Churchill College,
Cambridge, in July 1979. The second symposium was also held at Churchill
College on 30-31 July, 1981, and this, the third, took place at the same
college on 30-31 July, . 1983. The meeting was structured in a format
which we hoped would appeal to the full range of our membership. The
philosophy of the ADG is that medical microbiologists, veterinarians,
toxicologists and dental bacteriologists have much to learn from each
other and can best be achieved by bringing these various disciplines
together frequently and in informal surroundings. Again the symposium
was very generously sponsored by May and Baker Limited who met all costs
of the meeting and entertained us splendidly. David Jackson and Donald
Bedford were re- sponsible for coordinating with the ADG on behalf of
May and Baker and, as usual, gave us their full cooperation. This book
contains the full-length papers, followed by the posters presented at
the meeting. This book also serves as a vehicle for the abstracts of the
first meeting of the Society for Intestinal Microbial Ecology and
Disease, SIMED, held in Boston, Massachusetts. An introduction to this
new society by its President, Sydney M. Finegold, M.D., precedes the
abstracts. M.J. Hill VI CONTENTS Preface v List of contributors VIII
