Scientific Information
Presenting authors will be allowed to make
only one (1) oral presentation. We will accept more
than one (1) poster, however, the Organizing Committee will
make the final decision as to the number of posters
per presenter according to availability of space. Send all abstracts (indicating either oral or poster
presentation and topic number from the list under Conference Program
Overview, deadline is April 15, 2003) either by mail (hardcopy
and disk) or e-mail (preferred over mail) to:
Jim Miller
Department of Pathobiological Sciences
School of Veterinary Medicine
Louisiana State University
Baton Rouge, LA 70803 USA
E-mail: jmille1@lsu.edu
Notification of acceptance of abstracts is
May 15, 2003.
Abstracts
Abstract format requirements: MS Word or
WordPerfect (for disk and electronic submissions) to fit
a 7 x 18 cm box, Times New Roman font (10pt). Title (bold),
authors (* indicating presenting author) and affiliations
will be arranged in one block. Skip one line and then present
the text in one block. Entire abstract will be single spaced
with full justification (see example below). If a mailed
disk is defective, the hardcopy will be scanned into electronic
format. Any abstract that does not meet these requirements
will be edited accordingly, which may result in loss of
some text.

Infection with
gastrointestinal nematodes, particularly Haemonchus
contortus, is a major constraint to goat
production in the southeastern United States. The traditional control
method in this region is frequent use of anthelmintics,
which leads to increased rates of anthelmintic
resistance. The nematode trapping fungi Duddingtonia
flagrans was evaluated as an alternative to anthelmintic control. Five levels of D flagrans spores were fed to 15 two-year-old Spanish
meat goat does to evaluate effectiveness at reducing
larval development in fecal cultures. The treatment
concentrations were 1) 5 x 105 fungal spores/kg BW, 2) 2.5 X 105
spores/kg BW, 3) 105 spores/kg BW, 4) 5 x 104 spores/kg
BW, and 5) no spores. Each doe was fed individually for 14 d (day 1-7, feed ration+spore formulation, day 8-14, feed ration+no spores), and feces were
collected daily to determine FEC and to establish fecal
cultures. After incubation at 27 C for 10 d, infective larvae were
recovered from cultures by baermannization. The
highest dose level reduced larval development by 90% within 2 d, and this level
of reduction or higher (up to 98%) was maintained until 2 d after fungus
feeding was terminated. The medium dose levels reduced larval development
between 67 and 97%, and the lowest dose level between 50 and 73% over the same
time period. Larval development returned
to pretrial levels within 4 days of termination of
fungus feeding. D. flagrans appears to be an
effective tool for biocontrol of parasitic nematodes
in goats.
Oral Presentations
Only Microsoft PowerPoint presentations
will be accepted and used. Presenters need to bring a zip
or CD disk and it might be prudent to also have a backup
disk.
Presentations will be pre-loaded to correspond
to the schedule, so presenters will need to drop off their
disk in the speaker ready room the night before their talk.
There will be no setup to accommodate connecting personal
laptop computers. Presentations will be scheduled for
12 minutes followed by 3 minutes for discussion (time limits
will be strictly enforced).
Poster Presentations
There will be 3 poster sessions (0730-0900
Tuesday, Wednesday and Thursday) which will be accompanied
by a continental breakfast. Presenters are to be at their
posters on the assigned day to discuss their results and
answer questions. Presenters should plan to put their posters
up the evening before their session and take down at the
end of their session (space does not allow leaving them
up). Each poster should fit a space of 4 ft. (approx.
120 cm) height x 3 ft. (approx. 90 cm) width.
Workshops and Symposia
Coordinators are responsible for inviting
participants (there will be no compensation provided for
them) and running their session as they desire. Symposia
will be set up for multimedia (PowerPoint) presentations.
Audiovisual equipment will be determined by Workshop Coordinators.
