July 26 - August 17, 2007
Real Time Sessions: Tuesday evenings; July 31 and August 7, 2007; 8:30pm-10:00pm ET (USA)


This course is designed to help veterinary support staff understand the how and the why of the proper diagnosis and identification of common parasites in horses, cattle and small ruminants. Data will be presented to bring enthusiasm for the fecal flotation with centrifugation technique. Quantitative procedures to arrive at Eggs Per Gram (EPG) of feces will be presented.

Dr. Payne teaches parasitology at the College of Veterinary Medicine, Kansas State University and obtained her PhD in veterinary parasitology. She is the director of the parasitology division of the Kansas State Veterinary Diagnostic Laboratory that includes both large and small animal diagnostics. She is an equally talented instructor for veterinarians and veterinary staff and has an avid interest in providing valuable up-to-date information on parasites for any area. This course has been submitted for RACE approval for veterinarians and veterinary technicians.

Upon completion of this course, participants should be able to:

TEXTBOOK: TThere is no required textbook for this course.
The instructor has recommended the following texts:


Week 1: Techniques and Identification
Content: Why do eggs and oocysts float? Things you can do to make sure that they do. Fecal flotation with centrifugation is the best way to find what eggs and oocysts are present; quantitative techniques are the best way to find out how many eggs and oocytes are present. The Baerman technique will allow you to isolate and identify lung worm larvae. Eggs and oocysts of common parasites will be presented with helpful tips on how to make sure you know the difference and can pick out pseudoparasites as well.

Week 2: FECR tests and ectoparasites
Content: Fecal egg count reduction Tests (FECRT) the only way to know if your parasite control program is working or if anthelmintic resistance is a problem. Ectoparasites of horses, cattle and small ruminants: lice, mites, ticks and flies. Correct identification makes a big difference in treatment options and success.

Library materials will be made available prior to the topic week so participants will have plenty of time to prepare for the real time sessions and discussion.

Message board discussions regarding the topic presented will begin on the day the course opens and continue for one week following the last real time session. These discussions will be held in the VSPN CE course area.
