Clostridial enteric infections in domestic animals remain a substantia
l problem for producers, veterinary practitioners, and diagnosticians
in spite of the ready availability of putatively effective immunoproph
ylactic products An accompanying problem is the near-anecdotal nature
of much of our information on the incidence, prevalence, and nature of
many clostridial diseases. As traditional in vivo diagnostic methods
fall into increasing disfavor, the demand for rapid and definitive in
vitro diagnostics is increasing. Effectively addressing the challenges
of the future will be facilitated by accurate assessment of the incid
ence and/or prevalence of these infections and the informed participat
ion of diagnosticians and practitioners to better define clinical, mic
robiologic, and pathologic characteristics which may be useful in diag
nosis and improving immunoprophylactic products. Equally important wil
l be integration of the findings of laboratory research to provide dia
gnostic tools and application of these tools to rapid diagnosis, allow
ing timely application of therapy or prophylaxis.
