COURSE DESCRIPTION:  This course will introduce students to common internal and external parasites of veterinary importance.  Emphasis will be placed on morphological features of parasitic organisms, diagnosis & treatment of parasitic infection, including pathological changes to the host, and epidemiology of parasitic infections.

 

TEXTBOOK:       Parasitology Reference Manual, 5th edition (2001) by Foreyt

Laboratory Procedures for Veterinary Technicians, 4th edition (2002) by Hendrix.

READINGS:  Additional readings and activities may include handouts, computer exercises, and Internet sites

 

COURSE OBJECTIVES:

·         Describe the phenomenon of parasitism compared to other symbiotic relationships.

·         Identify the major taxa of parasites from the Phyla Acanthocephala, Arthropoda, Nematoda, Platyheminthes, and Kingdom Protista.

·         Learn the names, life cycles, hosts, and relative importance of common parasites of domestic animals.

·         Apply basic knowledge of modes and patterns of transmission and use of parasiticides to solve animal health problems associated with parasitism.

 

EXAMINATION AND GRADING:  Course grade for lecture will be based on examinations and class

attendance and participation.  The instructor reserves the right to normalize the overall grades and/or any individual set of grades.

LABORATORY

 

 

OBJECTIVES:

 

1.        To develop the skills necessary for diagnosing and intervening in parasitologic disease.

2.        To competently perform the following diagnostic procedures:  fecal floatation, direct fecal smears, Baerman exams, ELISA tests, Knott’s tests, filter tests.

3.        To become skillful in identifying the various parasite eggs, cysts, and larvae of domestic animals.

 

SPECIFIC ACTIVITIES:

 

1.        Perform diagnostic test on fecal and blood samples of animals and identify the parasite products present.  Document your results into the log book.

2.        Choose appropriate diagnostic test(s) based on the presenting history for each animal presented.

3.        Make recommendations for treatment and control based on the results obtained from the diagnostic tests and case history accompanying the sample.

4.        Completion of assigned case histories prior to laboratory period and discussion of case history during laboratory session.

 

SPECIFIC ASSIGNMENTS:

 

1.        Preparation for discussion of case histories assigned at the previous class period.

2.        Oral presentation of a parasitologic problem of veterinary or wildlife concern based on a published article from a recent (2000+) parasitology/veterinary journal (literature/internet).

These presentations should contain the following information

A.      Taxonomic placement of parasitic organism

B.       Life cycle – host(s), environmental stages, method of infection to host(s)

C.       Clinical history, symptoms, pathological changes (cause of disease)

D.      Treatment, control, and prevention

E.       Discussion of selected article with parasitological problem

3.        At the end of the semester, you will be given an “unknown” fecal sample to identify any parasite products.  You will report on your findings and answer questions
